Objective:To investigate the clinical efficacy of endoscopically-assisted, minimally-invasive transposition reconstruction with a double-bundle flexor hallucis longus (FHL) for chronic Achilles tendon ruptures.Methods:A retrospective study was conducted to analyze the clinical data of 36 patients with chronic Achilles tendon rupture who had been treated by endoscopically-assisted, minimally-invasive transposition reconstruction with a double-bundle FHL at Foot and Ankle Surgery Center, Foshan Hospital of Traditional Chinese Medicine from May 2015 to April 2020. The cohort consisted of 30 males and 6 females with an age of (42.1±16.5) years. Their body mass index was (28.5±4.5) kg/m 2, their length of Achilles tendon defect (51.0±15.0) mm, and their duration from injury to surgery (13.1±10.4) weeks. The Achilles tendon rupture score (ATRS), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, and Victorian Institute of Sports Assessment-Achilles (VISA-A) score were recorded and compared between pre-surgery and the last follow-up. All postoperative complications were record. Results:All patients were followed up for (41.3±3.5) months. No incision complications were noted. At the last follow-up, ATRS was (90.3±5.6) points, AOFAS ankle-hindfoot score (91.0±2.0) points, and VISA-A score (91.7±2.9) points, all significantly higher than the preoperative values [(24.3±8.2) points, (49.7±9.3) points, and (25.7±7.8) points] ( P < 0.05). Conclusion:The clinical efficacy of the endoscopically-assisted, minimally-invasive transposition reconstruction with a double-bundle FHL for chronic Achilles tendon ruptures is definite, leading to a low rate of complications.
