Femoroacetabular impingement (FAI) syndrome, a cause of hip pain, involves specific symptoms, signs, and radiographic findings. While physical therapy is recommended, surgery may be considered but carries risks and no guarantee of returning to sport.
Area of Science:
- Orthopedics
- Sports Medicine
- Hip Preservation Surgery
Background:
- Femoroacetabular impingement (FAI) syndrome is a significant cause of hip pain, particularly in athletes.
- The 2016 Warwick Agreement defined FAI syndrome by a triad of symptoms, signs, and radiographic findings.
- Cam morphology is linked to adolescent hip loading, while pincer morphology development is less understood.
Purpose of the Study:
- To review the current understanding and management of Femoroacetabular Impingement (FAI) syndrome.
- To evaluate the role of conservative treatments and surgical interventions for FAI.
- To identify prognostic indicators for surgical outcomes in FAI patients.
Main Methods:
- Literature review of recent studies on FAI syndrome.
- Analysis of diagnostic criteria and treatment modalities.
- Evaluation of surgical outcomes and complication risks.
Main Results:
- Physical therapy can improve pain and function in FAI patients, warranting a trial before surgery.
- Evidence for musculoskeletal injections in FAI is limited.
- Arthroscopic surgery can correct morphological abnormalities and soft tissue injuries.
- Presurgical osteoarthritis is a reliable indicator of surgical outcomes.
- Surgery offers efficacy but includes risks and no guarantee of return to pre-injury sport levels.
Conclusions:
- FAI syndrome management involves a stepwise approach, starting with conservative care.
- Surgical intervention for FAI is effective but requires careful patient selection.
- Pre-existing osteoarthritis significantly impacts surgical outcomes in FAI patients.
