Patellar Tendon Reconstruction Using Ipsilateral Hamstring or Peroneal Autografts - A Case Series of Five Patients
Abstract
Abstract Introduction: Although uncommon, chronic patellar tendon rupture and failure of primary repair can be challenging to treat and compromise the knee extensor mechanism. When tendon quality is poor and there is quadriceps contracture or fibrosis, repair may be limited, making patellar tendon reconstruction the preferred treatment approach. However, no unified view exists on the optimal graft selection for reconstruction of the patellar tendon. Case Series: This is a case series of five patients treated in a tertiary care facility between 2022 and 2025 for chronic or failed primary patellar tendon ruptures. In all five patients, reconstruction was performed using the ipsilateral hamstring or peroneal autografts. The harvested tendon was passed in a figure-of-eight fashion through trans-osseous tunnels created on the patella and the tibial tuberosity. The graft was then fixed to the tibia with bioabsorbable screws and suture anchors. Functional outcomes were evaluated at the final follow-up of 6 months, focusing on the range of motion, extensor lag, radiographic patellar height, and complications observed post-surgery. Results: At final follow-up, four out of five patients gained full active knee extension without any extensor lag, while one patient still had an extension lag of 20°. The range of knee flexion was 100–130°. No cases of re-rupture or fixation failure were observed. There was minimal donor-site morbidity, and no significant ankle instability was noted in…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
