This article describes a 22-year-old former collegiate football player who had his career cut short secondary to a chronic distal rupture of the biceps femoris at the knee. Reconstruction of the distal biceps femoris tendon with semitendinosus allograft resulted in an excellent clinical outcome and allowed the patient to return to a high level of physical activity. This case presents a unique cause of knee pain and weakness in a young, active patient and a corresponding effective surgical treatment for such an injury.

The purpose of this multicenter, randomized, double-blind controlled study was to compare the functional outcomes and healing rates after use of single-row and double-row suture techniques for repair of the rotator cuff. Ninety patients undergoing arthroscopic rotator cuff repair were randomized to receive either a single-row or a double-row repair. The primary objective was to compare the Western Ontario rotator cuff index (WORC) score at twenty-four months. Secondary objectives included comparison of the constant and american shoulder and elbow surgeons (ASES) scores and strength between groups. Anatomical outcomes were assessed with magnetic resonance imaging (MRI) or ultrasonography to determine the postoperative healing rates. Baseline demographic data including age (p = 0.29), sex (p = 0.68), affected side (p = 0.39), and rotator cuff tear size (p = 0.28) did not differ between groups. The...

With the purpose of surveying current practices and opinions concerning treatment of these lesions, we sent a questionnaire to members of a general orthopaedic society, a national shoulder society and an international shoulder society. Closed reduction was attempted by 52% of the respondents, but > 80% of the surgeons stated that the reduction was not maintained in more than half of the dislocations. The procedure preferred by the respondents--explicitly by members of the international shoulder society--to deal with chronic symptomatic anterior SC dislocation, is reconstruction of the ligaments. Members of the international shoulder society are more likely to choose operative treatment for chronic symptomatic anterior SC dislocations.

No previous RCT has compared arthroscopic Bankart repair with ETAC of the medial glenohumeral ligament and anterior band of the inferior glenohumeral ligament versus undergoing arthroscopic Bankart repair alone. Our hypothesis was that there would be no difference in quality of life between these two groups. Complication/failure rates were also compared. Eighty-eight patients were randomly assigned to receive arthroscopic Bankart repair with (n = 44) or without ETAC (n = 44). Post-operative visits occurred at 3, 6, 12, and 24 months with WOSI, ASES, and Constant scores completed, and rates of dislocation/subluxation were determined. Data on 74 patients were analysed, with the rest lost to follow-up. There were no differences between groups at any post-surgery time points for WOSI, ASES, or Cons...

We present a technique involving the use of the iliac crest allograft inserted into the glenoid defect in athletes with recurrent anterior shoulder instability and large bony defects of the glenoid (>25% of glenoid diameter). All athletes with recurrent anterior shoulder instability and a large glenoid defect that underwent open anterior shoulder stabilization and glenoid reconstruction with the iliac crest allograft were followed over a 4-year period. Preoperatively, a detailed history and physical exam were obtained along with standard radiographs and magnetic resonance imaging of the affected shoulder. All patients also completed the Simple Shoulder Test (SST) and American Shoulder and Elbow Surgeons (ASES) evaluation forms preoperatively. A computed tomography scan was obtained postoperatively to assess osseous union of the graft and the patient again went through a physical exam in addition to completing the SST, ASES, and Western Ontario Shoulder Instability Index (WOSI) forms. 10 patients (9 males, 1 female) were followed for an average of 16 months (4-36 months) and had a mean age of 24.4 years. All patients exhibited a negative apprehension/relocation test and full shoulder strength at final follow-up. Eight of 10 patients had achieved osseous union at 6 months (80.0%). ASES scores improved from 64.3 to 97.8, and SST scores improved from 66.7 to 100. Average postoperative WOSI scores were 93.8%. The use of the iliac crest allograft provides a safe and clinically useful alternative compared to previously described procedures for recurrent shoulder instability in the face of glenoid deficiency.

In the sagittal plane, the dependent variables were the angle of the tibial tunnel relative to the tibial plateau and the position of the tibial tunnel with respect to the most posterior aspect of the tibia. In the coronal plane, the dependent variables were the angle of the tunnel with respect to the medial joint line of the tibia and the medial and lateral placement of the tibial tunnel relative to the most medial aspect of the tibia. The position and angle of the tibial tunnel in the coronal and sagittal planes were determined from anteroposterior and lateral radiographs, respectively, taken 2-6 months postoperatively. The two-dimensional and three-dimensional guide groups included 28 and 24 sets of radiographs, respectively. Tibial tunnel position was identified, and tunnel angle measurements were completed. Multiple investigators measured the position and angle of the tunnel 3 times, at least 7 days apart. The angle of the tibial tunnel in the coronal plane using a two-dimensional guide (61.3 ± 4.8°) was more horizontal (P < 0.05) than tunnels drilled with a three-dimensional guide (64.7 ± 6.2°). The position of the tibial tunnel in the sagittal plane was more anterior (P < 0.05) in the two-dimensional (41.6 ± 2.5%) guide group compared to the three-dimensional guide group (43.3 ± 2.9%). The Howell Tibial Guide allows for reliable placement of the tibial tunnel in the coronal plane at an angle of 65°. Tibial tunnels were within the anatomical footprint of the ACL with either technique. Future studies should investigate the effects of tibial tunnel angle on knee function and patient quality of life. Case-control retrospective comparative study, Level III.
