Patellar tendon ossification is a rare pathology that may be seen as a complication after sleeve fractures of the tibial tuberosity, total patellectomy during arthroplasty, intramedullary nailing of tibial fractures, anterior cruciate ligament reconstruction with patellar tendon autograft and knee injury without fracture. However, its occurrence after partial patellectomy surgery has never been reported in the literature.
We present the case of a 35-year-old Turkish man with a comminuted inferior patellar pole fracture that was treated with partial patellectomy. During the follow-up period, his patellar tendon healed with ossification and then ruptured from the inferior attachment to the tibial tubercle. The ossification was excised and the tendon was subsequently repaired.
To the best of our knowledge, this is the first report of patellar tendon ossification occurring after partial patellectomy. Orthopaedic surgeons are thus cautioned to be conscious of this rare complication after partial patellectomy.
髌腱骨化是一种罕见的病理情况，可作为胫骨结节袖状骨折、关节置换术中全髌骨切除术、胫骨骨折髓内钉固定、自体髌腱重建前交叉韧带以及无骨折的膝关节损伤后的并发症出现。然而，文献中从未报道过部分髌骨切除术后发生髌腱骨化的情况。
我们报告一例35岁土耳其男性，因髌骨下极粉碎性骨折接受了部分髌骨切除术。在随访期间，其髌腱愈合并伴有骨化，随后从胫骨结节的下附着处断裂。切除骨化组织后，对肌腱进行了修复。
据我们所知，这是首次报道部分髌骨切除术后发生髌腱骨化的病例。因此，提醒骨科医生在部分髌骨切除术后要注意这种罕见的并发症。
