Patellar Tendon Reconstruction Using Hamstring Graft: A Case Report

Background: Patellar tendon ruptures presenting in a chronic setting are rare events that impose technical surgical challenges due to proximal retraction of the patella, quadriceps muscle atrophy and contracture, and peripatellar adhesions. Various reconstruction techniques have been described using different grafts and fixation methods; however, there is a paucity of reported out- comes and there is no consensus on standard of care. Indications: The patient is a young female of 18yrs who presented with a history of trauma to right knee and was diagnosed with chronic patellar tendon tear. The patient was indicated for patellar tendon reconstruction with autologous hamstring tendon graft due to chronicity of the injury. Method: Patellar tendon reconstruction using hamstrings graft and fixing with anchor suture and interference screw. Result: Achieving normal patella tendon height and complete range of motion with restoration of extensor mechanism of knee. Conclusion: Knee extensor mechanism disruptions necessitate prompt surgical correction. In patients with poor tendon quality and/or a history of knee arthroplasty, primary repair should be supplemented with autograft or allograft. Early repairs yield better results than late interventions, which necessitate intricate reconstructions to reestablish the extensor mechanism's continuity. Achieving early osteointegration of the graft is important in case of tendon reconstructive procedures such as in this case as it leads to better outcomes in terms of rehabilitation and early progress to daily activities.
