| Lead Author | Title | Surgery | Number of Participants | FUP | Age | Outcome |
|---|---|---|---|---|---|---|
| Chen H, (2009)10 | Drilling and microfracture lead to different bone structure and necrosis during bone-marrow stimulation for cartilage repair. | Microfracture | Animal Models | N/A | N/A | Demonstrated that microfracture can produce long term articular cartilage repair. |
| Philippon MJ (2008)12 | Can microfracture produce repair tissue in acetabular chondral defects? | Microfracture | 9 | 20 mths | N/A | 91% was the average fill of lesions after 20 months. However the range was from 25% to 100%. |
| Byrd JW (2009)15 | Arthroscopic femoroplasty in the management of cam-type femoroacetabular impingement. | Microfracture | 58 | 16 mths | 33 | 20 point improvement in harris hip scores. |
| Haviv B (2010)16 | Arthroscopic femoral osteochondroplasty for cam lesions with isolated acetabular chondral damage. | Microfracture | 29 | 22 mths | 37 | MHHS score improved by 12, NAHS improved by 13.2 |
| Murakibhavi V (2010)20 | Early results of Autologus Chondrocyte implantation in the hip. | ACI | 14 | 30 mths | N/A | mHHS score improved by 5 points. 5 patients underwent arthroscopy after 1 year. The results showed good integration of new cartilage. |
| Krych AJ (2011)23 | Treatment of focal osteochondral defects of the acetabulum with osteochondral allograft transplantation. | Allograft | 2 | 38 mths | 28 | significant pain improvements, MRI showed plug integration, mHHS scores improved from to 75-97 in 2 years for patient 1 and 79 to 100 in 3 years for patient 2. |
| Khanna V (2014)28 | Cartilage Restoration of the Hip Using Fresh Osteochondral Allograft: Resurfacing the Potholes. | Allograft | 17 | 42 mths | 25.9 (17 to 44) | 13/17 had good to fair results (extrapolated from mHHs scores). |
| Girard J (2011)29 | Osteochondral mosaicplasty of the femoral head. | Mosaicplasty | 10 | 29.2 mths | Above 25 | Range of motion increased from 175.4° to 210.7°. Merle d'Aubigné scores improved from 10.5 to 15.5 |
| Field RE (2011)30 | Arthroscopic grafting of chondral defects and subchondral cysts of the acetabulum. | Synthetic osteochondral plug | 4 | 10 mths | N/A | Non-arthritic hip score improved from 53.8 (range 43.8 to 70) pre-operatively to 84.6 (range 78.8 to 87.5) at 6 months. |
| Mancini D (2014)35 | Five-year results of arthroscopic techniques for the treatment of acetabular chondral lesions in femoroacetabular impingement. | AMIC | 31 | 60 mths | N/A | The mean mHHS improvement at the five year follow-up with respect to preoperative level was 39.1 ± 5.9 on chondral defects larger than 3cm². |
FUP, follow-up procedure; mHHS, modified Harris Hip Score; NAHS, Non-Arthritic Hip Score; ACI, autologous chondrocyte implantation.
