Abstract
PURPOSE: The purpose of this study was to evaluate the clinical outcomes of the endoscopic-assisted locking block modified Krackow technique with a V-Y flap. The hypothesis was that the minimally invasive technique can reduce wound complications and facilitate early recovery. METHODS: In total, 29 men with chronic Achilles tendon rupture who underwent either minimally invasive technique (n = 13) or open repair (n = 16) at our department between 2013 and 2019 were retrospectively analyzed. The rate of complications, time to return to moderate-intensity exercise, American Orthopedic Foot and Ankle Society ankle hindfoot score, Achilles tendon Total Rupture Score, heel-rise repetitions in 1 min, heel-rise height, and bilateral calf circumference at 6 months, 1 year, and 2 years postoperatively were recorded. RESULTS: All incisions healed primarily in the minimally invasive technique group; however, three patients in the open repair group experienced wound complications. The time to return to moderate-intensity exercise, American Orthopedic Foot and Ankle Society score, Achilles tendon Total Rupture Score, heel-rise repetition ratio, and heel-rise height ratio at 6 months postoperatively in the minimally invasive technique group were significantly better than those in the open repair group. However, it was not significantly different between both groups at 2 years postoperatively. CONCLUSION: Endoscopy allowed scar tissue and adhesions to be removed, allowing the tendon ends to be mobilized out of the small proximal and distal incisions. Minimally invasive technique may result in a lower wound complication incidence and provide better early functional recovery and return to moderate-intensity exercise time than the conventional open procedure in treating chronic Achilles tendon ruptures. CLINICAL TRIAL REGISTRATION: Wuxi Ninth People's Hospital Medical Ethical Committee, LW2021026. LEVEL OF EVIDENCE: III.
