• Status: Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 88 (estimated)
• Sponsor: Panam Clinic · Academic / Other
• Sex: All
• Age: 16 Years – 50 Years
• Healthy volunteers: Not accepted

Summary

The purpose of this single-blinded (assessor) randomized trial is to compare patient-reported, clinical and functional outcomes in patients randomized to weight-bearing as tolerated (WBAT) or partial weight-bearing (PWB) restrictions following arthroscopic surgery for femoroacetabular impingement (FAI) up to 12-months postoperative.

Detailed description

The purpose of this single-blinded (assessor) randomized trial is to compare patient-reported, clinical and functional outcomes in patients randomized to weight-bearing as tolerated (WBAT) or partial weight-bearing (PWB) restrictions following arthroscopic surgery for femoroacetabular impingement (FAI) up to 12-months postoperative. The primary objective is to compare the effects of WBAT or PWB restrictions on PROMS (International Hip Outcome Tool (iHOT33)) and clinical measures following arthroscopic intervention for FAI up to one-year post-operative. The secondary objective will be to assess differences in return to sport (RTS) PROMS, functional performance, and lower extremity kinetics, kinematics, and muscle activity during in patients randomized to either WBAT or PWB at six- and 12-months post-operative. The goal will be to answer if there are differences between a WBAT versus PWB rehabilitation protocol on patient-reported quality of life as measured by the International Hip Outcome Tool (iHOT33) at 12-m post-operative for patients undergoing primary hip arthroscopy for the treatment of FAI.

Conditions

• Femoro Acetabular Impingement

Interventions

Type	Name	Description
OTHER	Weight-bearing As Tolerated	The WBAT group will be instructed to bear weight as tolerated immediately following their surgical procedure. The rehabilitation protocols provided will be identical beyond the initial weightbearing recommendations. Following the initial protection phase (three weeks), whereby the two weightbearing interventions will be provided, patients will progress through standardized phases including mobility and neuromuscular retraining, muscle balance and strengthening, functional training, and finally, advanced training for return to work and sport.
OTHER	Partial Weight-bearing	The PWB group will be instructed to bear weight to a maximum of 20 lbs of bodyweight on the operative limb for the initial three weeks (termed "toe touch"), with graduated return to full weightbearing thereafter.
