Achilles tendon is one of the most commonly injured tendons in the human body. There are various factors that lead to its rupture. This can lead to restriction in movements. Surgical reconstruction is much more superior to conservative treatment. Transfer of flexor hallucis longus in Achilles tendon rupture is a newer procedure with not much studies regarding its functional efficacy. In this study we attempt to evaluate the functional outcome of end to end repair and flexor hallucis longus augmentation in tendo-achilles rupture. 20 patients with Achilles Tendon rupture admitted between June 2021 and November 2022 were recruited into the study. All patients were operated with end to end repair and Flexor Hallucis Longus (FHL)tendon augmentation. Functional outcome was analyzed using American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score. All patients were followed up to 6 months post-operatively. Outcome was assessed by AOFAS Ankle-Hindfoot (AHS) score. The mean preoperative score of 48.0 improved to 77.9 at final follow-up out of a total 100 points. We achieved excellent functional outcome in 10%, good outcome in 80% cases and moderate outcome in 10% cases. No re-ruptures were noted. Superficial infections were noted in 2 cases which was managed with oral antibiotics. ankle stiffness was found in 1 case which was managed with physiotherapy. The study concluded that in ruptures of Achilles tendon, FHL augmentation to calcaneum with interference screw fixation and end to end repair of Achilles tendon is a reliable technique with good functional outcome.
