University of Colorado Denver (CU Denver)

Status: Completed

Treatments: Procedure: Capsular Repair; Procedure: No Capsular Repair

Study type: Interventional

Funder types: Other

Identifiers

Details and patient eligibility

About

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.

Enrollment: 23 patients

Ages: 16 to 51 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Male or female patients aged between 16-51 years of age.

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.

Treatment:

Procedure: Capsular Repair

No Capsular Repair

Placebo Comparator group

Description:

Placebo arm. One hip is randomized to capsular repair while the other hip has no capsular repair.

Treatment:

Procedure: No Capsular Repair
