Loosening, Prosthesis Clinical Trial
Official title:
Optimising Recovery After Cup Revision - is the Anterior Approach Superior to Posterolateral?
With increasing numbers of total hip arthroplasties performed each year, the incidence of problems related to loosening and wear of total hip arthroplasties is expected to also increase. While the anterior approach for primary total hip arthroplasty has demonstrated to result in a faster short-term recovery than the traditional lateral and posterior approach, this effect has not yet been investigated in revision surgery. Accelerating functional outcome may increase patient satisfaction and reduce healthcare costs. The primary objective is to assess whether isolated cup revision surgery through the anterior approach results in increased functional status and higher patient satisfaction than through the posterolateral approach. This is a prospective Randomized Controlled Trial (RCT) in which 68 patients will be included (34 per group). Patients will be evaluated preoperatively and 6 weeks, 3 months and 1 year postoperatively. The main endpoints are functional recovery as measured with the 30-sec Chair Stand Test (30s-CST), 40m Fast Paced Walking Test (40m FPWT) and the Stair Climb Test (SCT). Secondary endpoints are Modified Borg scale outcomes after the functional tests, Numeric Rating Scale (NRS) for pain (rest/movement), Oxford Hip Score (OHS), HOOS-PS, EQ-5D-5L, satisfaction, cup inclination and complications at 30 days and 90 days postoperatively.
