Weightbearing Restrictions on Postoperative Outcomes Following Arthroscopic Surgery for FAI

Launched by PANAM CLINIC · Mar 14, 2022

ClinConnect Summary

This clinical trial is looking at how different weight-bearing restrictions after arthroscopic surgery for femoroacetabular impingement (FAI) affect recovery. Specifically, it compares two groups: one that is allowed to put as much weight on their hip as they can tolerate, and another that has to limit the weight they put on their hip. The goal is to see how these different approaches impact patient-reported outcomes, clinical results, and how well patients can function after the surgery, up to a year later.

To be eligible for this study, participants need to be between 16 and 50 years old and diagnosed with FAI, which involves pain and limited movement in the hip. They should have tried other treatments, like physical therapy, for at least three months without success. Participants will need to be willing to follow up for a year after their surgery. This trial is currently recruiting patients and aims to help determine the best way to support recovery after this type of surgery. If you qualify and choose to participate, you will be monitored closely to assess your recovery and functionality over the next year.

Eligibility criteria

• Inclusion Criteria:
• • 16 - 50 years of age at time of surgery
• * Diagnosis of FAI (cam, pincer, mixed) based on the 2016 Warwick Agreement. All 3 criteria below must be met:
• • 1. Symptoms of motion- or position-related pain in the hip or groin
• • 2. Clinical signs consistent with FAI such as: decreased hip flexion and internal rotation, or positive impingement sign
• • 3. Radiographic evidence (on BOTH x-ray AND non-contrast MRI) of intra-articular pathology consistent with FAI as determined by the treating surgeon.
• • Failed conservative interventions of at least 3 months (i.e. physiotherapy)
• • Have symptom relief with intra-articular injection of local anaesthetic
• • Unilateral or bilateral surgical intervention (note: unilateral required to ensure the weight bearing guidelines are followed)
• • Are willing to be followed for 12 months post-operative.
• Eligibility for 'return to sport' cohort:
• Additional assessment measures related to return to sport will be collected on the patient who meet the following criteria:
• • are or were previously actively involved in sport as indicated by a pre-operative Hip Sports Activity Scale score of four of greater
• • indicate a post-operative goal to return to sport following their procedure
• Exclusion Criteria:
• Clinical:
• • Previous surgery on the affected hip, or other major lower extremity orthopaedic surgery
• • Active joint or systemic infection, significant muscle paralysis, significant lower extremity or medical comorbidity that could alter the effectiveness of the surgical intervention (e.g. polymyalgia rheumatica)
• • Unable to speak or read English/French
• • Unable or unwilling to be followed for 1 year or complete functional testing
• • Presence of chronic pain syndromes
• • History of pediatric hip disease (i.e. Slipped Capital Femoral Epiphysis, Legg-Calve-Perthes Disease)
• • Ongoing litigation or compensation claims related to the hip (including Workers' Compensation)
• Radiographic:
• • Osteoarthritis greater than Tönnis Grade 1 on affected hip
• • Lateral central edge angle \<19°
• • Dysplasia in patients with broken Shenton line (i.e. Severe acetabular deformity present)
