Full weight-bearing after cementless total hip arthroplasty

In a prospective study of cementless total hip arthroplasty, 19 hips in 17 patients (Group A) were allowed full weight-bearing immediately after the operation while 18 hips in 16 patients (Group B) were first allowed weight-bearing after 6 weeks. Patients were matched for sex, age at surgery, height, weight, and follow-up period and there were no significant differences in hip scores between the two groups. Rehabilitation to gain walking ability with a cane lasted 5.8 days for Group A and 44.8 days for Group B (P=0.0001). The hospital stay after surgery was 30.1 days for Group A and 46.7 days for Group B (P=0.006). All patients showed bone ingrowth radiographically. There were no complications in either group.
