Short-term Results of Immediate Weight Bearing after Cementless THA.

We investigate the short-term results of immediate weight bearing after cementless THA. One hundred and seven hips of 102 patients were included in this study. Three different types of prosthesis were used. Patients were allowed full weight bearing three days after THA. Clinical and radiographical findings were observed for six months after surgery. Subsidence of the femoral prosthesis was observed in three hips. Two did not sustain injury. No other complications were observed. These three types of prosthesis had good initial stability for postoperative immediate weight bearing, and bone ingrowth may lead to the prosthesis.
