Capsular Repair in FAI Impingement Surgery

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02990234
Recruitment Status : Completed
First Posted : December 13, 2016

Brief Summary:
The Investigator's hypothesis is that capsular repair (after CAM or mixed Femoroacetabular Impingement (FAI) surgery) requiring moderate capsulotomy, would result in similar patient outcomes in the short, mid and long term, both clinically and radiographically, compared to those without capsular repair. The objective of this clinical trial is to evaluate the clinical efficacy with regards to pain, range of motion and return to work and activities of daily living. Secondary objective is to evaluate radiographic characteristics between both groups.

Arm Intervention/treatment
Active Comparator: Capsular Repair
Capsular Repair arm. The first hip is randomized, opposite treatment on second hip. One Hip will receive the capsular repair while the other hip will not.
Procedure: Capsular Repair
Placebo Comparator: No Capsular Repair
Placebo arm. One hip is randomized to capsular repair while the other hip has no capsular repair.
Procedure: No Capsular Repair

Primary Outcome Measures :
  1. Change in iHOT Version 12 [ Time Frame: Baseline, 6weeks, 12weeks, 6months, 1Year, 2Years ]

Other Outcome Measures:
  1. Change in Marx activity score [ Time Frame: Baseline, 6weeks, 12weeks, 6months, 1Year, 2Years ]
  2. Change in Range of Motion [ Time Frame: Baseline, 14days, 6weeks, 12weeks, 6months, 1Year, 2Years ]
  3. Change in X-rays [ Time Frame: 6weeks, 6months, 1Year ]
    XR will be used for initial evaluation and for post op resection assessment and long-term OA changes. X-rays will be done post-operatively at 6 weeks, 6 months and 1 year time-frames. All these x-rays are normally performed as standard of care.

  4. Change in MRI [ Time Frame: 6weeks, 6months ]
    MRI will be conducted at 6 weeks and 6 months post op to evaluate capsular healing status (primary radiological outcome measure), intra articular adhesions, extra articular scarring, labrum/cartilage status and resection assessment. This MRI will be paid by department funds.
