Background In the operative treatment of insertional Achilles tendinopathy, the Achilles tendon is often released from its insertion to allow for adequate debridement of pathologic tissue. The use of a double row suture anchor construct has become increasingly favorable among surgeons after Achilles tendon debridement. This study hypothesized that the addition of a Krackow rip stop suture augment to the double row suture anchor construct would increase the repair’s maximum load to failure. A biomechanically stronger repair would potentially decrease the risk of catastrophic failure with early weight-bearing or accidental forced dorsiflexion after operative management for insertional Achilles tendinopathy. Methods Fourteen cadaveric specimens were used to compare the 2 repair techniques. Achilles tendons were debrided and repaired using either a double row suture anchor with and without the additional Krackow rip stop suture augment. The 2 repair techniques were compared using an axial-torsion testing system to measure average load to failure. Results The average load to failure for the double row suture anchor repair alone was 152.00 N. The average load to failure for the tendons with the double row suture anchor with the Krackow rip stop augment was 383.08 N. An independent-samples Mann-Whitney U-test was conducted and the suture anchor plus Krackow augment group had a significantly higher load to failure ( P = .011, Mann-Whitney U = 5.00, n1 = n2 = 7, P < .05, 2-tailed). Conclusion This study confirmed that the addition of a Krakow rip stop augment to the double row suture anchor is able to increase the maximum load to failure when compared to the double row suture anchor alone. These results suggest the potential of this added technique to decrease the risk of catastrophic failure.

Abstract Background No conclusive evidence recommends a prior treatment for insertional Achilles tendinopathy (IAT). It is theorized that both percutaneous radiofrequency coblation and extracorporeal shockwave therapy (ESWT) relieve pain within the insertion. However, no clinical evidence shows that either treatment promote the regeneration of the tendon or if the combination of these 2 interventions offer better function and less pain than one therapy. Methods The study is a randomized, controlled trial with patients allocated in a 1:1 ratio to one of two parallel groups. Patients with insertional Achilles tendinopathy who are not satisfied with the effect of conservative treatment will be screened. A minimum of 38 patients will be enrolled after deciding to participate in the trial on an informed basis. Then the intervention group and the control group perform radial ESWT and sham-ESWT respectively at 6 months after percutaneous radiofrequency coblation. The primary outcome will be the Victorian Institute of Sports Assessment Achilles (VISA-A) Score. Secondary outcome measures will be Foot and Ankle Outcome Score (FAOS) scale, Visual Analogue Scale (VAS), Tegner Score, and MRI ultra-short echo time (UTE) T2* value. The assessments will occur in 6 months, 1 year, and 2 years post-operatively. The differences between 2 groups will be conducted as intention-to-treat basis. Discussion We aim to investigate if radiofrequency coblation associated with ESWT can provide more encouraging imaging findings as well as functional and clinical outcomes regarding the treatment of the IAT comparing to the single radiofrequency coblation treatment.

Background: The aim of this study was to assess the patient-reported outcome measures (PROMs) in patients with insertional Achilles tendinopathy (IAT) treated surgically by debridement of all pathologies through a midline-incision trans-achillary approach (MITA). Methods: This is a retrospective cohort study with current follow-up. Patients treated surgically by a MITA, addressing all pathologies of IAT, with at least 12 months of follow-up were included. Demographics, medical history, surgical details, and complications were recorded. Patient-reported outcomes were assessed using the Foot Function Index (FFI), Victorian Institute of Sport Assessment–Achilles questionnaire (VISA-A-G), visual analog scale foot and ankle (VAS-FA), and 12-Item Short-Form Health Survey (SF-12). Longitudinal FFI data were available for 48% of the patients. Results: A total of 118 patients (63.4%) with a mean follow-up of 50 ± 25 months were included. The FFI improved from 53 (24) preoperatively to 2 (11) points at the final follow-up. The final VISA-A-G score was 93 (26), the VAS-FA score 93 (15), the SF-12 Physical Component Summary 56 (8), and the SF-12 Mental Component Summary 55 (12) points. There was an additional FFI improvement between 12 months and the final follow-up. Up to 47% (VISA-A-G) of patients had residual symptoms. A postoperative shoe conflict was the only parameter negatively affecting the PROMs ( P < .001). Conclusion: Addressing all pathologies of IAT by the MITA resulted in overall good postoperative PROMs after 4 years. But up to 47% of patients remained impaired. The only parameter correlating with an impaired PROM was a postoperative shoe conflict. Level of Evidence: Level IV, retrospective cohort study.

Background: Surgical treatment of insertional Achilles tendinopathy with Haglund deformity in highly competitive professional athletes has not been previously investigated. Purpose: To assess clinical outcomes, including return to play (RTP), after surgical treatment of insertional Achilles tendinopathy in professional athletes. Study Design: Case-control study; Level of evidence, 3. Methods: This retrospective study included 20 professional athletes who were surgically treated for insertional Achilles tendinopathy and had at least 2 years of follow-up. An open longitudinal lateral approach was used for the operation, without violation of the Achilles tendon. Outcome evaluation included American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, subjective patient satisfaction, mean time of return to competition (RTC), and rate of RTP. We defined RTC as return to an official match for at least 1 minute and RTP rate as the percentage of patients who were able to participate in at least 2 full seasons. A subgroup analysis was performed to compare the RTP and no-RTP groups. Results: The AOFAS score improved significantly from preoperatively to the final follow-up (from 65.1 to 88.4; P < .001), and 75% of the patients reported good to excellent satisfaction. The mean time of RTC was 7.45 months (range, 4-18 months), and the rate of RTP was 60%. The RTP group had a significantly lower mean body mass index than did the no-RTP group (22.03 vs 23.86, respectively; P = .005) and faster mean RTC (5.0 vs 11.1 months, respectively; P < .001). Conclusion: Open calcaneoplasty for surgical treatment of insertional Achilles tendinopathy with Haglund deformity in highly competitive professional athletes should be approached cautiously. Our patients had a 7.5-month recovery period before return to their first official match, and only 60% of the patients returned to their sports activity and participated in at least 2 full seasons. Lower body mass index and a faster RTC after surgery were related to longer functional maintenance.
