Abstract:Objective To investigate the clinical effect of repairing the Achilles tendon cicatrix tissue for the treatment of chronic Achilles tendon ruptures. Methods A cross-sectional study was conducted on 21 patients with chronic Achilles tendon ruptures who had been treated operatively at the Department of Orthopedics, First Affiliated Hospital of the University of Science and Technology of China, from August 2018 to July 2021. Among the patients, 17 were males and 4 were females, aged 20-73 (43.5±16.0) years old. Eleven cases were on the right side, and 10 cases were on the left side. All cases were used to heal chronic Achilles tendon ruptures by repairing the Achilles tendon cicatrix tissue. The operation time, incision length, postoperative complications, and time of return to daily activities and sports were recorded. The American Foot and Ankle Surgery Association (AOFAS) ankle-hindfoot score and the visual analogue scale (VAS) were compared before and after the last follow-up. The Achilles tendon complete rupture score (ATRS), Arner-Lindholm score, and single-legged heel rise height test were recorded in the last follow-up. Results The operation time of patients was 30-50 minutes (average of 41.1 minutes), and the incision was 4-7 cm long (average of 5.6 cm). No serious complications, such as infection, sural nerve injury, or re-rupture, were observed after operation. All patients were followed up for 6-40 months (mean of 18.5 months). The average time of return to daily activities was (4.4±0.7) months, and the average time of return to sports was (11.1±1.5) months. The AOFAS ankle-hindfoot score increased from the preoperative (63.5±6.9) to (89.9±4.8) in the last follow-up with statistical significance(t=-14.45, P<0.001). VAS decreased from preoperative 4 (3,4) to 0(0,1)in the last follow-up with statistical significance (Z=5.69, P<0.001). The mean ATRS in the last follow-up was (92.7±3.6) points. The Arner-Lindholm score was excellent in 15 cases and good in 6 cases, and the good rate was 100%. The positive rate of the single-legged heel rise height test was 9.52%(2/21), and the average single-foot calf raise recovery time was 4-7 (5.1±0.9) months. Conclusion The application of repairing the Achilles tendon cicatrix tissue in the treatment of chronic Achilles tendon ruptures has satisfactory clinical efficacy and shows the advantages of safety and few complications.
