Abstract
Introduction: Few guidelines indicate immediate unrestricted weight bearing after cementless total hip arthroplasty (THA). Stability and ingrowth may be jeopardized by immediate loading of the implant while functional recovery may be promoted. Patients & Methods: This is a prospective study on 20 patients who managed with cementless THA and then randomized into immediate unrestricted group and graduated weight-bearing group. Clinical assessments used Harris hip score (HHS) and short physical performance battery (SPPB) immediately after surgery (initial assessment) and then 6 and 12 weeks postoperatively. Radiographs were evaluated for vertical migration of femoral stem. Results: There was no statistically significant difference between the HHS and SPPB measured at different times of assessment in the 2 studied groups. In unrestricted weight-bearing group, no statistically significant difference in radiological vertical micro-migration of femoral stem between different assessment times was found; while in graduated weight bearing, there was statistically significant increase in the radiological vertical micro-migration of femoral stem measured at 6 and 12 weeks when compared to initial assessment. Conclusion: No adverse effect of immediate unrestricted weight bearing with cementless THA was found.
