Such complex injuries should be diagnosed and treated as early as possible. Initial open reduction and stable anatomical fixation are the keys to achieve a good functional outcome in such kind of injuries. Periprosthetic patellar fracture after total knee arthroplasty (TKA) is an uncommon yet devastating complication, and management of these fractures is challenging with unreliable results. An isolated bilateral patellar fracture is often associated with systemic diseases, steroid usage, and repeated microtrauma. Isolated simultaneous bilateral periprosthetic patellar fracture after TKA is seldom reported in the literature. This report consists of two cases of simultaneous isolated closed bilateral eriprosthetic patellar fracture after TKA, treated with open reduction and internal fixation of patella using tension band wiring. Union was achieved in both cases with satisfactory knee range of motion without significant extension lag. Regardless of the fact that surgical outcome of periprosthetic fracture of the patella has unpredictable and poor results in past, it can be considered for acute traumatic periprosthetic patella fractures with less comminution and good bone stock to avoid revision arthroplasty and poor outcome.

Perthes disease often results in a non-spherical deformed femoral head which causes pain, dysfunction, early degeneration, and arthritis in young adults. The importance of preservation of native hip in young adults has been well proven. We report a case of deformed Perthes head treated with femor
