Comparison of Tendon Lengthening with Traditional vs. Accelerated Rehab Following Achilles Tendon Repair: A Randomized Controlled Trial

Objectives: Operative repair of Achilles tendon ruptures have shown successful outcomes. However, little is know about the amount of tendon or repair site lengthening after repair and if lengthening is affected by rehab protocols. The purpose of our study was to compare lengthening of the Achilles tendon after surgical repair, comparing traditional and accelerated rehab protocols. Methods: Twenty patients undergoing primary repair of Achilles tendon ruptures were assessed for participation. We performed a prospective randomized controlled trial in accordance with the CONSORT (Consolidated Standards of Reporting Trials) 2010 statement. The study arms included operative repair of Achilles tendon rupture with either accelerated (graduated weight bearing at 2 weeks) or traditional rehab (weight bearing at 6 weeks). During repair, two 2-mm tantalum beads with laser-etched holes were sutured to the Achilles tendon at the repair site. Beads were evaluated via CT scans immediately post-operatively and at 12 weeks. X-rays were obtained at time 0 and then at 2, 6, and 12 weeks. The primary outcome of the study was the difference in tendon or repair site lengthening between the study arms. Randomization was by a computerized algorithm. The observer was blinded and the patient was not blinded to the intervention. Results: Zero patients declined participation and all 20 patients were included for final analysis. All patients showed statistically significant lengthening at two weeks following surgery. There was a trend toward increased lengthening at 6 weeks in the accelerated rehab group (9.9mm, range 2.6 -13.9mm) compared to the traditional rehab group (4.1mm, range 1.5 -9.0mm), although this was not statistically significant; p = .07. However the final amount of tendon lengthening at 12 weeks after surgery was not different between the accelerated rehab group (14.4mm, range 11.7 -17.0mm) and the traditional rehab group (13.4mm, range 10.7 -17.0mm); p = .38. Conclusion: This study\u27s findings suggest that all patients undergoing operative repair of Achilles tendon ruptures have significant lengthening after surgery. Although there was a trend toward increased lengthening at 6 weeks in the accelerated rehab group, there was no difference in tendon lengthening at final follow up between the two groups

Extensor Mechanism Ruptures and Reruptures: Perioperative Opioid Management

The purpose of this study was to determine (1) the correlation between preoperative and postoperative opioid use and (2) risk factors associated with rerupture in patients undergoing open extensor mechanism repair. A retrospective review of patients who underwent operative repair of quadriceps or patellar tendon rupture was performed. Patients were classified as opioid nonusers if they had not received any opioid medications in the 3 months before surgery, or as acute users or chronic users if they received at least one opioid prescription within 1 month or 3 months preceding surgery. Clinical records were reviewed for postoperative opioid use within a year after surgery as well as rerupture rates. A total of 144 quadriceps tendon and 15 patellar tendon repairs were performed at a mean age of 56.8 ± 15.1 years and body mass index of 33.2 ± 7.1. The overall rerupture rate was 6%. Diabetes was a significant risk factor for rerupture (56 vs. 19%, p = 0.023). Chronic preoperative opioid users were more likely to continue to use opioids beyond 1 month postoperatively (p \u3c 0.001) as compared with acute or nonopioid users. Chronic preoperative opioid users (relative risk [RR]: 3.53, 95% confidence interval [CI]: 2.11-5.90) and patients with longer anesthesia time (RR: 1.39, 95% CI: 1.00-1.93) required more monthly opioid refills, whereas tourniquet use required fewer opioid refills each month (RR: 0.57, 95% CI: 0.37-0.88). Compared with patients without a rerupture, each additional prescription refill after the initial repair in the rerupture group was associated with a 22% higher risk of tendon rerupture (RR: 1.22, 95% CI: 1.07-1.39). The chronicity of preoperative opioid intake was found to have a significant effect on postoperative opioid use. This study suggests that there is a higher prevalence of rerupture in patients with prolonged opioid use postoperatively and among diabetics

Comparison of Tendon Lengthening With Traditional Versus Accelerated Rehabilitation After Achilles Tendon Repair: A Prospective Randomized Controlled Trial

BACKGROUND: Early weightbearing protocols after Achilles tendon repair promote mobilization, yet little is known about their effect on tendon lengthening. PURPOSE: To evaluate tendon lengthening after Achilles tendon repair with accelerated rehabilitation. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: Patients undergoing primary repair for acute Achilles tendon ruptures consented to have tantalum beads placed within the tendon. Patients were randomized into either a traditional (weightbearing at 6 weeks) or accelerated (graduated weightbearing at 2 weeks) rehabilitation group. The primary outcome of the study was postoperative tendon elongation as measured by radiostereometric beads. Secondary outcomes included Achilles Tendon Total Rupture Score (ATRS) and Patient-Reported Outcomes Measurement Information System Pain Interference Short Form (PROMIS PI-SF) score. RESULTS: All 18 patients included in the final analysis were found to have significant tendon lengthening after surgery, with a mean lengthening of 15.9 mm. No significant differences were found in overall lengthening between the traditional and accelerated rehabilitation groups (15.3 ± 4.5 vs 16.4 ± 4.7 mm, respectively; CONCLUSION: This study\u27s findings demonstrate that all patients undergoing operative repair of Achilles tendon ruptures had lengthening after surgery. No difference was found in tendon lengthening (repair site or intratendinous) at any time point between patients undergoing traditional versus accelerated rehabilitation postoperatively. The greatest amount of lengthening was found to occur between 2 and 6 weeks postoperatively, and tendon lengthening decreased significantly after 6 weeks
