Abstract
Introduction: A chronic patellar tendon rupture in adolescent is very rare but can happen in sport-related injury. Presentation at more than 6 weeks after injury might cause a significant disability. Prompt diagnosis and treatment are key factors to a good prognosis. In this case, we use an autologous semitendinosus tendon graft to repair the patellar tendon rupture. Case Report: A 17-year-old male presented with pain at left knee since 6 months ago. The pain started after he landed on his left knee, having jumped while playing volleyball. On physical examination of the left knee, edema and high patella were found. There was also a palpable gap at the inferior pole of the patella. The patient was unable to do active extension of the left lower leg. MRI evaluation of the left knee revealed a patellar tendon rupture, myositis ossificans and a partial ACL rupture. The patient was scheduled for an elective surgery, consisting of patellar tendon reconstruction using an autologous semitendinosus graft along with ossificans removal and debridement. Discussion: Risk factors of tendon rupture should be assessed with extensive evaluation to construct the appropriate surgical repair method. The decision on which method to use depends greatly on the patient's profile and nature of injury. Immobilization period and routine rehabilitation exercises are vital to an enhanced recovery and fully functional knee. Conclusion: An autologous semitendinosus graft provides a good result without the need of a steel wire, as demonstrated in our case. Immobilization period and routine rehabilitation exercises are vital to an enhanced recovery and fully functional knee.
