A common cause of hip joint pain in the young and active population is femoroacetabular impingement (FAI) syndrome. if FAI is left untreated, the changed morphology will have a negative effect on the existing joint and will contribute to the development of osteoarthritis (OA). Hip arthroscopy is the first choice of operative treatment for FAI. While hip arthroscopy improves the patient reported outcome measures (PROMs), the influence of this treatment on the contribution to the development of osteoarthritis after FAI is to the best of our knowledge still unknown.
Study Type
OBSERVATIONAL
Enrollment
451
Patients will be asked to visit the clinic for a bilateral hip x-ray, in order to evaluate the degree os osteoarthritis.
Patients will be asked to complete questionnaires on function, quality of life and pain (the modified Harris Hip Score (mHHS), Hip Outcome Score (HOS), the World Health Organisation Quality of Life Questionnaire (WHOWOL) and Visual Analogue Scale (VAS) for pain). One question will be asked: 'How satisfied are you with the results of the surgery?' on a 10-point scale.
Reinier Haga Orthopedic Center
Zoetermeer, Netherlands
To evaluate the degree of osteoarthritis 5 to 10 years after a hip arthroscopy in comparison with the non-operative side.
To evaluate the degree of osteoarthritis, the Kellgren and Lawrence-scale will be used. The scale ranges from 0 to 4: A score of 0 indicates that there is no evidence of osteoarthritis A score of 4 indicates end-stage OA, marked by severe sclerosis, joint space narrowing (sometimes bone-on-bone contact), and large osteophytes.
Time frame: 5 to 10 years after hip arthroscopy
To evaluate the change in degree of osteoarthritis at 5 to 10 years after a hip arthroscopy in comparison with preoperative/perioperative.
To evaluate the degree of osteoarthritis, the Kellgren and Lawrence-scale will be used. The scale ranges from 0 to 4: A score of 0 indicates that there is no evidence of osteoarthritis A score of 4 indicates end-stage OA, marked by severe sclerosis, joint space narrowing (sometimes bone-on-bone contact), and large osteophytes.
Time frame: 5 to 10 years after hip arthroscopy
To report incidence of total hip replacement within 5 to 10 years after a hip arthroscopy.
survival of the hip arthroscopy (defined by the incidence of total hip replacement) will be presented as a percentage of the total study population.
Time frame: 5 to 10 years after hip arthroscopy
To determine the functional outcome of patients and, to determine what factors contribute to a good functional outcome 5/10 years after hip arthroscopy.
Functional outcomes measured with patient reported outcome measures (PROMs) at 5 to 10 years after hip arthroscopy.
Time frame: 5 to 10 years after hip arthroscopy
To determine the inter-rater and intra-rater agreement of the Kellgren and Lawrence OA score.
The scale ranges from 0 to 4: A score of 0 indicates that there is no evidence of osteoarthritis A score of 4 indicates end-stage OA, marked by severe sclerosis, joint space narrowing (sometimes bone-on-bone contact), and large osteophytes.

Time frame: 5 to 10 years after hip arthroscopy
To determine patient satisfaction 5-10 years after hip arthroscopy.
One question on satisfaction will be asked: 'How satisfied are you with the results of the surgery?' on a 10-point scale. With 0 being not satisfied and 10 being very satisfied.
Time frame: 5 to 10 years after hip arthroscopy
