Early Improvement in Postoperative Clinical Outcomes without Patellar Resurfacing in Patella-Friendly Design of Medial Pivot TKA.

There is continued debate about the efficacy and indications for patellar resurfacing in total knee arthroplasty (TKA), especially with the emergence of patella-friendly designs. This study aimed to compare the postoperative outcomes in patients undergoing TKA with or without patellar resurfacing using the same implant design. This is a retrospective cohort study of patients who underwent TKA including those with patellar resurfacing (PR group) and those without (NPR group).

Giant cell tumor of bone: a report of two cases with metaphyseal lesions and their progression to the articular surface.

Two patients presented to outside providers with joint pain. Both had isolated lytic metaphyseal lesions on plain radiographs that were not noted or acted upon. Subsequent radiographs showed large expansile lytic lesions involving the metaphysis and epiphysis extending to the subchondral bone.
