Is Periacetabular Osteotomy Superior to Progressive Resistance Training?

Hip Dysplasia Clinical Trial

Official title: The Effect of PAO Followed by Progressive Resistance Training Versus Progressive Resistance Training in Patients With Hip Dysplasia. A Randomized Controlled Trial

Status Active, not recruiting

Clinical Trial Summary

The primary aim of this study is to examine if Periacetabular Osteotomy (PAO) followed by 4 months of usual care followed by 8 months of progressive resistance training (PRT) is superior to 12 months of a PRT intervention in patients with hip dysplasia eligible for PAO in terms of self-reported pain on the HAGOS questionnaire. Secondary aims are to investigate changes in patient-reported symptoms, physical function in daily living, physical function in sport and recreation, hip and/or groin-related quality of life, generic health status, functional performance, muscle strength, physical activity and adverse events between PAO followed by usual care+PRT compared to PRT only. We hypothesise that in patients with hip dysplasia, PAO followed by usual care+PRT, results in significantly less pain at 12 months follow-up, compared to PRT only.

Clinical Trial Description

Group 1 (PAO+usual+PRT): PAO will be performed as the trans-sartorial approach or the anterior pelvic approach. Patients commence post-operative rehabilitation as usual and follow the rehabilitation program guided by a physiotherapist specialized in hip problems until 4 months after the operation. 4 months postoperative the patients complete usual care and continue with the same PRT intervention program as the PRT group, with 4 months of supervised sessions (see description below). Group 2 (PRT): The PRT group receives 4 months of supervised PRT 2 times per week. A physiotherapist or students will supervise all training sessions the first 4 weeks. The following 4 weeks, 6 out of 8 training sessions are supervised and from week 9-16, half of the training sessions (8 out of 16) are supervised. After these 4 months (16 weeks), patients receive a free membership to a fitness center near their home address and are encouraged to train on their own 2 times per week until 12 months follow-up with one supervised session per month. The PRT program involves 10-min of warm up followed by 50-min of bilateral resistance exercises including sets of loaded squats, hip extension, hip flexion, and hip abduction. The absolute training load will be individually adjusted on a set-by-set basis, using the plus two principle (if the patient is able to perform two or more repetitions than required, the load is increased). Hip related pain levels up to 5 on the VAS is considered acceptable during exercise. The study is a multicentre randomised controlled and assessor blinded trial. Primary endpoint will be 12 months after initiation of surgical/non-surgical treatment. Secondary endpoints will be measured at 4 months after the start of the treatment (surgical/non-surgical). In addition, 5-year and 10-year follow-up with questionnaires is planned. ;
