Osteophytes removal in patella versus lateral facetectomy of the patella in patella-retaining total knee arthroplasty

BACKGROUND In this study, the results of the partial lateral facetectomy of the patella to better patellofemoral motion and congruence are compared with the results of the osteophyte removal of the patella and neurectomy only in total knee arthroplasty (TKA). METHODS Data from 55 patients undergoing TKA with osteophytes removal of the patella and neurectomy only, and those undergoing osteophy...

Chondrosarcoma of the patella

RATIONALE Chondrosarcoma, characterized by the production of cartilage matrix, is a common bone tumor, accounting for 20% to 27% of all malignant bone tumors. It often occurs in the cartilage of the pelvis, femur, tibia, and humerus. However, chondrosarcoma of the patella is extremely rare. PATIENT CONCERNS The present study describes a case of chondrosarcoma affecting the right patella in a ...

Fractures of the patella.

THIS paper records an attempt made in 1956 to evaluate the long-term results of repair and excision of the fractured patella in an area where displaced transverse fractures were repaired and displaced comminuted fractures were excised. It is not a common injury. The Sunderland Hospitals serve some 400,000 people, but we were able to collect only 76 cases requiring operation between I936 and 195...
