A rare case of superior patellar dislocation with intact extensor apparatus of the knee and a minor avulsion fracture of the patellar apex
Superior dislocation of the patella is an exceptionally rare condition in musculoskeletal trauma. Furthermore, its detachment from the tendinous structures of the extensor mechanism while maintaining its knee extensor mechanism tendon, appears to be the first such injury reported in the literature....

| Summary: | Superior dislocation of the patella is an exceptionally rare condition in musculoskeletal trauma. Furthermore, its detachment from the tendinous structures of the extensor mechanism while maintaining its knee extensor mechanism tendon, appears to be the first such injury reported in the literature. This article presents the case of a 44-year-old male who sustained this injury following a low-energy knee trauma, compounded by a minor avulsion fracture of the patellar apex and damage to the medial retinacula.This study aimed to present the diagnostic process, the surgical treatment applied, and the assessment of postoperative outcomes. The patient underwent arthroscopy and arthrotomy to stabilize the dislocation and repair the stabilizing structures of the patella. The surgical treatment resulted in the patient’s return to activity and satisfactory functional recovery.This case underscores the importance of prompt diagnosis and appropriately tailored surgical intervention in achieving successful outcomes in the management of superior patellar dislocations. |
