Outcomes of arthroscopic treatment of femoroacetabular impingement
| Study | Number of patients | FAI type | Mean follow-up duration | Outcomes |
|---|---|---|---|---|
| Philippon, 200947 | 112 | Cam (23), pincer (3), combined (89) | 2.3 years | HHS: 23 to 84, p<0.001 |
| Byrd, 200948 | 200 (207 hips) | Cam (163), combined (44) | 1.3 years | Modified HHS: 83% showed significantly improved outcome at 2 years |
| Domb, 201349 | 20 (arthroscopic) vs 10 (open treatment) | Cam or combined | 2 years | HOS and NAHS significantly improved at 2 years |
| Larson, 200950 | 75 | Labral debridement (36), repair (39) | 1 year | Labral repair group showed improved radiological outcome and HHS good or excellent in 89.7% vs 66.7% |
| Sampson, 200551 | 183 (194 hips) | Combined | 2.5 years (maximum) | 94% pain free on flexion and rotation at 2.5 years |
| Ilizaliturri, 200752 | 13 | Combined | 2.5 years | WOMAC®: 4 to 14, p<0.01 |
| Ilizaliturri, 200853 | 19 | Cam | 2 years | 82% pain free at 2 years |
| Philippon, 200854 | 16 | Cam (2), pincer (5), combined (6) | 1.4 years | HHS; HOS; significantly improved clinical outcomes for all patients |
| Bardakos, 200855 | 24 | Cam | 1 year | HHS: good or excellent in 83% compared with 60% in control group |
| Stähelin, 200856 | 22 | Cam | 0.5 years | VAS; NAHS; significantly improved outcomes in all patients at 6 months |
| Schilders, 201157 | 96 (101 hips) | Combined | 2.44 years (median) | Improved HHS; greater effect with labral refixation |
| Larson, 201258 | 94 hips (50 with labral refixation, 44 without) | Pincer or combined | 3.5 years | Improved HHS, SF-12® and VAS for both groups, significantly greater improvement with labral refixation |
FAI = femoroacetabular impingement; HHS = Harris hip score; HOS = hip outcome score; NAHS = non-arthritic hip score; WOMAC® = Western Ontario and McMaster Universities; VAS = visual analogue scale; SF-12® = Short Form 12
