Evaluation of Uncemented Total Hip Arthroplasty in Patients With Avascular Necrosis of the Femoral Head

Thirty-seven uncemented primary porous coated anatomic (PCA) total hip arthroplasties (THA) that were performed in 33 patients for the diagnosis of avascular necrosis (AVN) between June 7984 and December 7986 were reexamined at four- to six-year follow-up periods. Final clinical evaluation showed an 86-point average Harris hip rating (range, 47-700 points), which had improved from an average preoperative rating of 42 points (range, 20-61 points). Thigh pain, which was usually not functionally limiting, occurred in 11 patients (25%), and seven patients (16%) had a moderate or severe limp. Nine patients (20%) required the use of a cane
