Several nonoperative options have been recommended for the treatment of knee osteoarthritis (OA), with varying degrees of evidence. Adhering to the American Academy of Orthopaedic Surgeons clinical practice guidelines has been suggested to decrease direct treatment costs by 45% in the year before knee arthroplasty, but this does not consider the cost of the entire episode of care, including the cost of surgery and postsurgery care. To analyze the total treatment costs after a diagnosis of knee OA, as well as the proportion of arthroplasty interventions as part of the total knee OA-related costs, and whether the total costs differed for patients who received intra-articular hyaluronic acid and/or had knee arthroplasty. We identified patients newly diagnosed with knee OA using the 5% Medicare data sample from January 2010 to December 2015. Patients were excluded if they were aged <65 years, had incomplete claim history, did not reside in any of the 50 states, had claim history <...

BackgroundTo evaluate changes in pain, function, and quality of life after treatment with injected micro-fragmented adipose tissue (MFAT) for knee osteoarthritis in a large cohort of individuals treated at multiple centers. MethodsOne hundred ten individuals were recruited from three private outpatient clinics. Participants had to be diagnosed with symptomatic knee OA (defined by persistent knee pain associated with clinical symptoms of OA and/ or classic imaging findings) and who had not received prior knee surgery or treatment with platelet-rich plasma, cortisone, or hyaluronic acid within the previous 6 weeks. Data from 120 knees were included in the analysis. Outcome measures included Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales (pain, symptoms, activities of daily living [ADL], sports and recreation, quality of life [QOL]) and an 11-point Numerical Rating Scale (NRS) for average knee pain over the past week. Outcomes were collected at baseline and 3, 6, and 12 ...

Myofascial pain syndrome (MPS) is difficult to treat. The efficacy and safety of tizanidine, an alpha2-adrenergic agent with effects on spasticity and pain, in treating MPS was evaluated. Female subjects (n = 29) with MPS of 9 to > 52 weeks' duration and mean age 37.5 (range 20-51) years, who also had reduced pressure thresholds, were enrolled. Subjects were titrated up to 12 mg of tizanidine over 3 weeks and maintained for 2 weeks. Sleep was assessed via visual analog scale (VAS), pain intensity via short form McGill questionnaire including VAS, disability/level of function, and pressure threshold (tested by algometry) at baseline, weeks 3 and 5, and 1 week after tizanidine was discontinued. Patient and physician global assessments of treatment were reported at week 5. Twenty-four subjects completed the study. Pain intensity and disability decreased significantly from baseline at weeks 3 and 5 and after washout (P < .001). Pressure threshold and sleep improved for all stu...

Aim: We studied changes in opioid prescriptions and corticosteroid injection use for knee osteoarthritis patients before and after intra-articular hyaluronic acid (HA) use and opioid prescriptions before and after knee arthroplasty (KA). Materials & methods: A total of 1,017,578 knee osteoarthritis members were ascertained from a commercial claims database (Health Intelligence Company LLC, IL, USA) using ICD9/ICD10 diagnosis codes. Results: Eighty two percent of HA patients did not fill opioid prescriptions postinjection, with 54% of opioid users discontinuing fills. Two-thirds of KA patients filled opioid prescriptions within 6 months postsurgery, with 78% of opioid users continuing fills and 62% of nonusers initiating use. Conclusion: Alternative therapies, such as HA, that reduce opioid use may alleviate opioid addiction risks for KA patients who use opioids in the pre- and postoperative periods.

To characterize graduating physical medicine and rehabilitation (PM&R) residents physicians' perceptions of their current musculoskeletal (MSK) training, to identify barriers perceived by resident physicians to improving MSK education experiences, and to compare the views of resident physicians with those of PM&R residency program directors. Fourth-year PM&R residents graduating in 2004 whose program directors attended the 2004 Association of Academic Physiatrists annual meeting were asked to complete an MSK education survey developed by the authors. Data were compared with a previous MSK education survey that had been completed by PM&R residency program directors. Ninety-three of 156 (61%) fourth-year PM&R residents responded after multiple contacts. According to residents, the most frequently used MSK education formats during residency were MSK lecture series, MSK journal clubs, and MSK workshops. Potential barriers to improved MSK education during residency included staff, money, and time. If given unlimited resources, most residents would greatly increase the use of visiting lecturers, MSK workshops, and MSK lecture series. Graduating PM&R residents as well as residency program directors indicated a strong interest in expanding resident MSK education through the use of visiting lecturers. Differences were noted with respect to the use of hands-on learning (i.e., MSK workshops [residents]) vs. passive learning (i.e., CD ROMS/DVDs and videos [program directors]). Both groups described how limited resources including staff, money, and time are barriers to resident MSK education.

To assess whether athletes with strength imbalance of the hip musculature would be more likely to require treatment for low back pain (LBP) over the ensuing year. The study population included 163 National Collegiate Athletic Association Division I college athletes (100 males and 63 females) undergoing preparticipation sports physicals. Institutional review board approval was obtained to acquire and analyze hip muscle strength data. A commercially available dynamometer (Chatillon, Lexington, KY) incorporated into a specially designed anchoring station was used for testing the hip extensors and abductors. The maximum force generated for the hip abductors and extensors was used to calculate a percentage difference between the right and left hip extensors and abductors. Treatment of athletes by the athletic trainers for LBP unrelated to blunt trauma over the ensuing year was recorded. Of all athletes, 5 of 63 females and 8 of 100 males required treatment for LBP. Logistic regression analysis indicated that for female athletes, the percentage difference between the right and left hip extensors was predictive of whether treatment for LBP was required over the ensuing year (P = 0.05). There was no significant association noted for the percentage difference between the right and left hip abductors in females and for the percentage difference between both the right and left hip abductors and right and left hip extensors in males requiring treatment for LBP. These data support our results from our previous cohort study, adding validity to the concept of hip muscle imbalance being associated with LBP occurrence in female athletes. This research further supports the need for the assessment and treatment of hip muscle imbalance in individuals with LBP.

Continuous passive motion (CPM) has been commonly used in the postoperative rehabilitation of patients after total knee arthroplasty. In the acute care hospital, most studies have found CPM to be useful in improving range of motion and reducing length of stay. The benefit of CPM in the rehabilitation hospital has not been studied. The charts of 61 patients who had undergone total knee arthroplasty and subsequently were admitted to the East facility of the Kessler Institute for Rehabilitation were reviewed. Patients were separated into two groups: Group 1 received CPM for 3 to 4 hours/day and physical therapy for 2 hours/day. Group 2 received only physical therapy. There was no significant difference in passive range of motion or length of stay between Group 1 and Group 2. An analysis of the 16 patients who underwent bilateral replacement was undertaken. Patients in Group 1 (n = 7) achieved an average increase in passive range of motion of 20.1 degrees, whereas those in Group 2 (n = 9) achieved an increase of 12.7 degrees (P = 0.18). Power analysis demonstrated the need for 50 patients per subgroup to achieve significance. The lack of statistical significance in this subgroup may be a reflection of the small study population (n = 16). The following conclusions can be drawn concerning the use of CPM in the rehabilitation setting: (1) CPM was of no added benefit to those patients admitted after single knee replacement, and (2) CPM may be beneficial to those patients admitted after bilateral knee replacement.

Platelet-rich plasma (PRP) is an orthobiologic treatment that has gained popularity as a potential alternative treatment for various musculoskeletal conditions. The physiologic role of platelets in the healing cascade provides clarity regarding its potential as it releases various growth factors such as platelet-derived growth factor (PDGF), transforming growth factor beta-1 (TGF-β1), and vascular endothelial growth factor (VEGF). However, there are various characteristics of PRP treatments including platelet count, presence or absence of leukocytes and red blood cells, as well as the use of an activating agent that introduces heterogeneity among preparations. This aim of this article is to provide clarity, where available, regarding the optimal characteristics for PRP treatments regarding tendon and ligament injuries as well as articular and muscular pathology.

The majority of the provocative tests described for physical examination of the neck and cervical spine relate to identification of radiculopathy, spinal cord, or brachial plexus pathology. These tests are often performed routinely by many providers with variable methods and interpreted in a variety of ways. Several commonly performed provocative tests include Spurling's Neck Compression Test, Shoulder Abduction (Relief) Test, Neck Distraction Test, L'hermitte's Sign, Hoffmann's Sign and Adson's Test. This review describes some specialized provocative tests with comprehensive literature review. The goal of this review is to develop standardization in the performance and clinical use of these tests. Each of the tests described in this manuscript apparently originated from the anecdotal observations of experienced, well respected clinicians. However, only few studies have been performed addressing the interexaminer reliability or validity of these tests. The existi...

STUDY DESIGN A case report of unrecognized lumbarization of the S-1 vertebral body leading to wrong-level disc surgery in a patient with acute cauda equina syndrome secondary to a large disc extrusion at the L4-L5 interspace. Laminectomy and excision were initially performed at the level of L5-L6. OBJECTIVES To review the importance of detection of lumbosacral transitional vertebrae when performing interventional procedures in the lumbar spine. SUMMARY OF BACKGROUND DATA Lumbosacraljunction transitional vertebrae have been well documented. Likewise, surgery at the wrong intervertebral level has been reported as a reason for failure of lumbar spine surgery. There is also brief mention in the literature of lumbar disc surgery performed at incorrect levels in part secondary to junctional anomalies. However, there is no recorded case of wrong-level disc surgery in acute cauda equina syndrome occurring as a result of an unrecognized lumbarization or sacralization of transitional vertebra...

Significant variability exists in the literature, with no clear consensus to the optimal protocol after a regenerative procedure. Given this uncertainty, the authors systematically reviewed the literature cataloging the different variables that may influence outcomes. Search was limited to randomized clinical trials and prospective cohort studies of regenerative procedures for the treatment of tendinopathy. Variables were predetermined, and included: cyrotherapy, pre- and post-procedure nonsteroidal anti-inflammatory drugs use, recommendations for alternative pain medications, immobilization and duration of rest. Variables were categorized based on the influence of the intervention on the three phases of healing. 749 studies were assessed for eligibility, and 60 studies were included. Significant variability existed in the literature. Despite the importance of rehabilitation after regenerative procedures, there is a paucity of evidence available to guide clinicians and highlights th...

The application of regenerative therapies for the treatment of musculoskeletal conditions has emerged over the last decade with recent acceleration. These include prolotherapy, platelet-rich plasma, and mesenchymal stem cell therapy. These strategies augment the body's innate physiology to heal pathologic processes. This article presents an overview of platelet-rich plasma and mesenchymal stem cell therapy for the treatment of musculoskeletal injuries. A brief literature review is included, as are techniques for the use of ultrasound guidance to assist with these procedures.

rotator cuff tear affects many people. Natural history, and evidence for non-operative treatment remains limited. Our objective is to assess evidence available for the efficacy and morbidity of commonly used systemic medications, physiotherapy, and injections alongside evaluating any negative long-term effects. a systematic search was performed of PubMed, Cochrane, EMBASE and CINAHL dates (1 January 1960 - 1 December 2014), search terms: 'rotator cuff tear', 'natural history', 'atraumatic', 'injection',…

Editors' prefaceThe management of chronic low back pain (CLBP) has proven very challenging in North America, as evidenced by its mounting socioeconomic burden. Choosing amongst available nonsurgical therapies can be overwhelming for many stakeholders, including patients, health providers, policy makers, and third-party payers. Although all parties share a common goal and wish to use limited health-care resources to support interventions

Chronic proximal patellar tendinopathy is a common condition in sports medicine that may be refractory to nonoperative treatments, including activity modification, medications, and comprehensive rehabilitation. Percutaneous ultrasonic tenotomy is a recently developed technique designed to cut and debride tendinopathic tissue, thus promoting pain relief and functional recovery. We present a case of a collegiate athlete with chronic proximal patellar tendinopathy who was effectively treated with percutaneous ultrasonic tenotomy after not responding to extensive nonoperative treatment, surgical debridement, and platelet-rich plasma injections. Percutaneous ultrasonic tenotomy can be considered as a treatment option in patients presenting with refractory proximal patellar tendinopathy, including those who do not respond to previous operative intervention.

involving repetitive forced dorsiflexion of the ankle. This condition can lead to significant dysfunction, especially in the elite athlete and younger population. This case provides an example of how dynamic US can be used to reveal AAIS and direct clinical management. Conclusion: Dynamic US may be used to demonstrate AAIS and potentially differentiate between soft-tissue and bony impingement. US-guided injection can be targeted to area of soft tissue impingement. Further studies are needed to investigate the utility of dynamic US in the detection of AAIS.

accuracy improved significantly from 30.8% on pre-class assessment to 65.4% on post-class assessment (P1⁄4.022). Overall knee lateral joint line palpation accuracy improved from 50.0% on pre-class assessment to 65.4% on post-class assessment (P1⁄4.344). Conclusion: Joint line palpation accuracy of the AC and lateral knee joint line in first-year medical students is low after conventional MSK physical examination education. A 2-hour physical examination class using MSK ultrasound to provide direct feedback to medical students on the accuracy of their palpation skills improved palpation accuracy of the AC and knee lateral joint lines 1 week later. The utilization of MSK ultrasound is a novel and effective method of teaching the MSK physical examination to medical trainees.

In-line skating has become a very popular sport over the past several years. Previous studies examining the injuries associated with this sport have emphasized the incidence upper extremity injuries. Two cases are described in which patients suffered severe lower extremity injuries while in-line skating: one had a femoral shaft spiral fracture and the other bilateral anterior cruciate ligament and medial collateral ligament injuries. Although a predominance of upper extremity injuries associated with this sport has been widely noted, increased numbers of participants, higher speeds and changing skate designs may further predispose skaters to leg, knee and ankle injuries.

Autologous cell therapies including platelet-rich plasma (PRP) and bone marrow concentrate (BMC) are increasingly popular options for soft tissue and joint-related diseases. Despite increased clinical application, conflicting research has been published regarding the efficacy of PRP, and few clinical publications pertaining to BMC are available. Preparations of PRP (and BMC) can vary in many areas, including platelet concentration, number of white blood cells, presence or absence of red blood cells, and activation status of the preparation. The potential effect of PRP characteristics on PRP efficacy is often not well understood by the treating clinician, and PRP characteristics, as well as the volume of PRP delivered, are unfortunately not included in the methods of many published research articles. It is essential to establish a standard reporting system for PRP that facilitates communication and the interpretation and synthesis of scientific investigations. Herein, the authors pro...

SUMMARY There is considerable interest amongst clinicians and researchers to create the optimal platelet product to maximize outcomes with platelet-rich plasma (PRP) injections. PRP has been widely introduced as a safe alternative for treating tendinopathies. However, there is still limited clinical evidence describing the components of the platelet product and supporting its use in clinical trials. This article reviews the current literature regarding the role of PRP injections in the treatment of recalcitrant tendinopathies and the different factors in the platelet product that could affect the outcome, including the platelet count, presence of leukocytes, activators used, pH of solution and delivery method, among others. In addition, we address important concepts regarding rehabilitation after PRP procedures, which has little consensus to date and is the subject of much debate. Based on the phases of soft tissue healing, basic science research on platelets, as well as our clinica...

Traditional treatment of sports injuries includes use of the PRICE principle (Protection, Rest, Ice, Compression, Elevation), nonsteroidal anti-inflammatories, physical therapy modalities, and corticosteroid injections. Recent evidence has raised concerns over this traditional treatment approach regarding the use of anti-inflammatories and injectable corticosteroids. More recent treatments, known as regenerative medicine, include platelet-rich plasma and stem cell therapies. Evidence for their efficacy in a variety of sports injuries has emerged, ranging from tendinopathy and muscle tears to ligament and chondral injuries. This article reviews the literature regarding established treatments for sports injuries and these more innovative treatments.

A 71-year-old generally healthy woman presents for her first visit in 3 years. She ambulates slowly from the waiting room, with a more stooped posture than previously. She reports a 2-year history of slowly worsening buttock and leg pain when she walks any distance. She has noticed that her symptoms are much less when she leans on a shopping cart in the grocery store. Her buttock/leg pain resolves within a few minutes when she sits down. The patient exhibits signs and symptoms suggestive of lumbar spinal stenosis.

People aged 65 years and over make up the fastest growing demographic in the United States. By the year 2040 they will comprise approximately one fourth of the US population. The elderly patient in need of chronic pain therapy presents challenges best met with an enlightened and effective treatment strategy. Practice standards must include a thorough pain assessment and formation of a multimodal care plan, which applies knowledge of pain management in an objective and scientific manner. In this article, a patient case study illustrates how the appropriate management of chronic pain in an elderly patient can lead to better clinical outcomes.

The prescription of medications continues to be one of the mainstays of treatment of acute low back pain episodes. The goals of the pharmacologic treatment for acute low back are reduction of pain and return of normal function. Often, nociception is a result of secondary inflammation and muscle spasm after acute injury of a structure of the spine, which may include muscle, tendon, ligament, disc, or bone. An understanding of the appropriate use of medications to address the underlying pain generator and the current evidence for using these medications is essential for any physician who sees and treats patients with acute low back pain.

Basketball is one of the most popular sports in the United States and throughout the world, and therefore represents one of the most common sources of sports-related injuries. Basketball injuries should be managed by the same general rehabilitation principles as other sports injuries. Additionally, the clinician should be aware not only of general sports injuries but of those injuries most commonly seen in basketball players. By maintaining knowledge of the most common basketball injuries as well as their diagnosis and treatment, the clinician can help to optimize the athlete's return to play and enjoyment of the sport.

Myofascial pain syndrome (MPS) is difficult to treat. The efficacy and safety of tizanidine, an alpha2-adrenergic agent with effects on spasticity and pain, in treating MPS was evaluated. Female subjects (n = 29) with MPS of 9 to > 52 weeks' duration and mean age 37.5 (range 20-51) years, who also had reduced pressure thresholds, were enrolled. Subjects were titrated up to 12 mg of tizanidine over 3 weeks and maintained for 2 weeks. Sleep was assessed via visual analog scale (VAS), pain intensity via short form McGill questionnaire including VAS, disability/level of function, and pressure threshold (tested by algometry) at baseline, weeks 3 and 5, and 1 week after tizanidine was discontinued. Patient and physician global assessments of treatment were reported at week 5. Twenty-four subjects completed the study. Pain intensity and disability decreased significantly from baseline at weeks 3 and 5 and after washout (P < .001). Pressure threshold and sleep improved for all stu...

Although soccer has a lower injury rate than does American football, injuries to the head and neck do occur. Indeed, soccer is classified as a contact sport. The potential for cervical injuries from the maneuver known as "heading" are of particular concern. This review provides a synopsis of soccer-related head and neck injuries, an overview of the biomechanics of trauma, and a rational approach to evaluating patients. This review was conducted to assess and evaluate existing literature on the biomechanics of the act of heading in soccer and the potential for acute and long-term injury to the head and neck. The resulting work is based on literature searches of the PubMed and Medline databases, textbook reviews, and bibliographies of articles and textbooks obtained during the search. Findings from several studies were summarized and critiqued. Biomechanics, anatomy, pathophysiology, and their relation to the act of heading in soccer were also synthesized into the discussion...

Commonly prescribed drugs for the treatment of low back pain have varying success rates, costs, and complications. This chapter presents current information on acetaminophen, nonsteroidal anti-inflammatory agents, muscle relaxants, opioids, corticosteroids, antidepressants, and colchicine to help the physician in determining a pharmacologic strategy.
