HAFAI Cohort 5 Year Follow up of Patients With Femoroacetabular Impingement Undergoing Hip Arthroscopy

Study Overview
=================
Brief Summary
-----------------
Patients included in the HAFAI cohort will be invited for 5 year follow up.

Detailed Description
-----------------
Patients with femoroacetabular impingement will be investigated 5 years after surgery. We will used the Copenhagen Hip and Groin Score to evaluate pain, activities of daily living, sport, participation in sport and hip-related quality of life. Furthermore, degree of hip osteoarthritis will be evaluated using standing x-rays. Last, we will investigate number of re-operations and conversions to total hip replacement.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain 5 years after surgery | Pain 5 years after surgery measured with the Copenhagen hip and groin scale (0-100 score) | Score at 5 years and change from before surgery to 5 years after surgery | 
| Sports function 5 years after surgery | Sports function 5 years after surgery measured with the Copenhagen hip and groin scale (0-100 score) | Score at 5 years and change from before surgery to 5 years after surgery | 
| Development of osteoarthritis 5 years after surgery | Lateral hip joint space width measured at anterior posterior standing radiographs | Score at 5 years and change from before surgery to 5 years after surgery | 
| Re-operation | Re-operation/total hip replacement | From date of initial surgery until the date of first documented re-operation or total hip replacement, whichever came first, assessed up to 6 years after initial surgery | 

Secondary Outcome Measures
