ABSTRACT
Introduction: Chronic patellar tendon injury is one of the most common overuse pathologies encountered in sports. In cases of chronic rupture, reconstruction using grafts becomes a necessary option to restore proper tendon length and restore knee function. Among the various graft options, hamstring autografts (hamstring tendon grafts) have emerged as a promising option for chronic patellar tendon reconstruction. This review aims to evaluate clinical outcome of hamstring autograft for chronic patellar tendon injury reconstruction.
Method: A systematic review - meta-analysis was conducted following the PRISMA guidelines. Relevant articles published from 2010-2025 were identified from PubMed, Google Scholar, and Cochrane. Pooled analysis of mean difference and 95% CI were initially conducted, followed by an evaluation of overall heterogeneity using Chi-Square and I2 test.
Result: Four studies were included (65 patients with chronic patellar tendon injury). Meta-analysis showed the patellar tendon reconstruction using hamstring autograft was associated with significant improvements, by improving knee flexion (MD = –8.85O, 95% CI = (–12.09) - (–5.61)), extension lag (MD = 17.03o, 95% CI = 16.61 - 17.46), and Insall-Salvati Index (MD = 0.31, 95% CI= 0.22 - 0.39).
Conclusion: Reconstruction of chronic patellar tendon injury using hamstring autografts provides significant improvements in clinical outcomes.
