“…Satisfactory clinical results after MFx of the hip [9,13,[39][40][41], including athletes [10,42], have been recently reported; however, the follow-up reported for MFx in the hip did not exceed two years [10,40,43]. In comparison, knee MFx, which is also known to be effective for lesions ≤2 cm 2 , has seen 47-80 % of cases reporting deterioration of knee function after two years [44].…”

Purpose This study assesses and compares the clinical outcomes of the arthroscopic matrix-induced autologous chondrocyte implant (MACI) and autologous matrix-induced chondrogenesis (AMIC) techniques for the treatment of acetabular chondral defects between 2 and 4 cm 2 consequent to femoral acetabular impingement. Methods Fifty-seven consecutive patients were treated with the MACI (n=26) or AMIC (n=31) technique. Patients were assessed pre-operatively and up to five years using the modified Harris Hip Score (mHHS) to compare outcomes. Results In both the MACI and AMIC groups, significant hip score improvements were measured over baseline levels at six months post-op (81.2±8.4 for MACI, 80.3±8.3 for AMIC, both p<0.001). The mHHS continued to improve up to three years post-op and remained stable over time until the final five year follow-up. Statistically significant differences between the groups were not observed. The mean mHHS improvement at the five year follow-up with respect to preoperative level was 37.8±5.9 and 39.1±5.9 in patients who underwent MACI and AMIC, respectively (NS). Subgroup analysis of both MACI and AMIC treatment outcomes for patients with an initial chondral defect larger than 3 cm 2 yielded comparable results at each time point. Conclusions This study suggests that both arthroscopic MACI and AMIC are valid procedures to repair mediumsized chondral defects on the acetabular side of the hip found during treatment of femoroacetabular impingement. Due to its high sustainability and minimal invasiveness, the single-stage AMIC procedure can reduce total treatment time and minimise morbidity while providing the same beneficial effects as the two-stage MACI intervention.

“…Studies show that the presence of OA negatively impacts outcomes after hip arthroscopy and nonarthroplasty open hip surgery [2,4,8,13,14,17,18,23,25,27,[29][30][31][32]35]. However, most studies predate FAI correction, are limited to small numbers, or lack well-defined independent predictors of improved function or failure rates after managing FAI in the presence of OA.…”

“…This disorder can result in labral-chondral injury and eventual osteoarthritic changes in the hip [2,7,10,25,29]. Numerous studies show the presence of OA negatively impacts improvements in pain and function after hip arthroscopy and nonarthroplasty open hip surgery [2,4,8,13,14,17,18,23,25,27,[29][30][31][32]35]. However, the majority of these studies predate resection of FAI impingement lesions [4,8,13,17,18,23,27,35], or are limited to small numbers [2,14,25,32].…”

Background Previous studies reporting the impact of osteoarthritis (OA) on pain and function after hip arthroscopy largely predate resection of femoroacetabular impingement (FAI). Questions/purposes We determined (1) functional improvement after resection of FAI impingement lesions in patients with preoperative radiographic joint space narrowing, and (2) identified preoperative predictors of pain, function, and failure rates in these patients.

“…Studies on outcomes after arthroscopic correction of FAI have found negative influences of OA on postoperative outcomes [14,20,21]. Preoperative radiographic joint space narrowing, together with preoperative MHHS score, and labral débridement or repair, predicted 35% of postoperative MHHS [20], and generalized severe cartilage lesions intraoperatively led to high rates of arthroplasty within 3 years of arthroscopy [12]. Increasing preoperative joint space narrowing has been shown to be an independent predictor for poorer outcome with respect to postoperative MHHS scores and undergoing arthroplasty in a recent cohort undergoing arthroscopy for FAI [14].…”
