Purpose
The goal of this systematic review was to present the current best evidence for clinical outcomes of osteochondral autograft transplantation to elucidate the efficacy of this procedure.

Methods
PubMed, CINAHL, and the Cochrane Central Register of Controlled Trials were searched (key terms “knee,” “osteochondral autograft transfer,” or “mosaicplasty”) to identify relevant literature between 1950 and 2013 in the English language. This evaluation included studies in pediatric and adult patients with grade 3 or 4 articular cartilage injuries; the studies had a minimum of 25 patients and at least 12 months of follow-up and compared osteochondral autograft transfers/mosiacplasty with another treatment modality. Articles were limited to full-text randomized controlled trials or cohort studies. Main outcomes studied were patient-reported and functional outcome, with secondary outcomes including effect of lesion size, return to sport and sport function, radiographic outcomes, and reoperation rates.

Results
There were a total of 9 studies with 607 patients studied in this systematic review. When osteochondral autologous transfer/mosaicplasty (OATM) was compared with microfracture (MF), patients with OATM had better clinical results, with a higher rate of return to sport and maintenance of their sports function from before surgery. Meanwhile, patients who underwent MF trended toward more reoperations, with deterioration around 4 years after surgery. When compared with autologous chondrocyte implantation (ACI), clinical outcome improvement was not conclusive; however, at 10-year follow-up, a greater failure rate was found to be present in the OATM group.

Conclusions
Current evidence shows improved clinical outcomes with OATM when compared with preoperative conditions. These patients were able to return to sport as early as 6 months after the procedure. It could be suggested from the data that OATM procedures might be more appropriate for lesions that are smaller than 2 cm2 with the known risk of failure between 2 and 4 years. Further high-quality prospective studies into the management of these articular cartilage injuries are necessary to provide a better framework within which to target intervention.

Level of Evidence

Purpose: The purpose of this study was to quantify the current trends in knee cartilage surgical techniques performed in the United States from 2004 through 2011 using a large private-payer database. A secondary objective was to identify salient demographic factors associated with these procedures.

Methods: We performed a retrospective database review using a large private-payer medical record database within the PearlDiver database. The PearlDiver database is a publicly available, Health Insurance Portability and Accountability Act–compliant national database compiled from a collection of private insurer records. A search was performed for surgical techniques in cartilage palliation (chondroplasty), repair (microfracture/drilling), and restoration (arthroscopic osteochondral autograft, arthroscopic osteochondral allograft, autologous chondrocyte implantation, open osteochondral allograft, and open osteochondral autograft). The incidence, growth, and demographic factors associated with the surgical procedures were assessed.

Results: From 2004 through 2011, 198,876,000 patients were analyzed. A surgical procedure addressing a cartilage defect was performed in 1,959,007 patients, for a mean annual incidence of 90 surgeries per 10,000 patients. Across all cartilage procedures, there was a 5.0% annual incidence growth (palliative, 3.7%; repair, 0%; and restorative, 3.1%) (P = .027). Palliative techniques (chondroplasty) were more common (>2:1 ratio for repair [marrow-stimulation techniques] and 50:1 ratio for restoration [autologous chondrocyte implantation and osteochondral autograft and allograft]). Palliative surgical approaches were the most common technique, regardless of age, sex, or region.

Conclusions: Articular cartilage surgical procedures in the knee are common in the United States, with an annual incidence growth of 5%. Surgical techniques aimed at palliation are more common than cartilage repair and restoration techniques regardless of age, sex, or region.

Level of Evidence: Level IV, retrospective database analysis.
