摘要

Purpose To systematically review randomized controlled trials to compare clinical outcomes of microfracture (MFx) versus third-generation autologous chondrocyte implantation (ACI) for the treatment of focal chondral defects (FCDs) of the knee joint. Methods A systematic review was performed by searching PubMed, Cochrane Library, and EMBASE to locate randomized controlled trials comparing minimum 2-year clinical outcomes of patients undergoing MFx versus third-generation ACI for FCDs of the knee joint. The search terms used were: “knee” AND “microfracture” AND “autologous chondrocyte” AND “randomized.” Patients were evaluated based on treatment failure rates, magnetic resonance imaging, International Cartilage Repair Society scores, and patient-reported outcome scores (Lysholm, Tegner, Knee Injury and Osteoarthritis Outcome Score, modified Cincinnati Knee Rating System, 12-item Short Form Health Survey Physical and Mental, and the EuroQol 5 Dimensions Visual Analog Scale score). Results Six studies (5 Level I, 1 Level II) met inclusion criteria, including a total of 238 patients undergoing MFx and 274 undergoing ACI. Two studies had an overlapping cohort of patients and therefore the study with longer follow-up was used in all analyses. The average follow-up among patients ranged from 2.0 years to 6.0 years. Average lesion size ranged from 1.8 cm2 to 5.0 cm2. Treatment failure ranged from 0% to 1.8% in the ACI group and 2.5% to 8.3% in the MFx group. In 4 studies, ACI patients demonstrated significantly greater improvement in multiple Knee Injury and Osteoarthritis Outcome Score subscores compared with MFx. In 2 studies, patients who received ACI demonstrated significantly greater improvement in the Tegner score compared to MFx, and 1 study showed significantly greater improvement in the Lysholm and ICRS scores for ACI compared with MFx. Conclusions At short-term follow-up, third-generation ACI demonstrates a lower failure rate and greater improvement in patient-reported outcomes compared with MFx for FCDs of the knee joint. Level of Evidence II, systematic review of Levels I-II studies.
