Abstract:
OBJECTIVE:To compare the clinical outcomes of microfracture and autogenous osteochondral mosaic transplantation in the treatment of knee joint cartilage injury.
METHODS:A retrospective analysis of 71 patients with articular cartilage defects on the femoral condyles who were by autogenous osteochondral mosaic transplantation or microfracture from February 2011 to February 2016, and these patients were followed up for at least 2 years. According to the sugical procedures, the patients were divided into two groups. In the microfracture group, there were 33 patients, 20 males and 13 females, with a mean age of(28.1±4.2) years old; in the mosaicplasty group, there were 38 patients, 26 males and 12 females, with a mean age of(27.8±3.5) years old. The Lysholm knee score, Hospital for Special Surgery (HSS) knee score and the Ahlbäck classification grade were recorded to evaluate the clinical efficacy. Complications were also recorded.
RESULTS:The mean Lysholm scores of the microfracture group and the mosaicplasty group improved from 62.9±6.8 and 60.3±7.5 preoperatively to 77.0±5.4 and 85.8±5.6 post-operatively, respectively(<0.05). Mean HSS scores of the microfracture group and the mosaicplasty group improved from 81.5±7.6 and 79.6±8.6 preoperatively to 88.0±4.7 and 91.9±4.7 post-operatively, respectively(<0.05). The mean Lysholm score and HSS score were significantly higher in the mosaicplasty group than those in the microfracture group at the latest follow-up. One patient in the mosaicplasty group suffered superficial wound infection. During the follow-up, no knee osteoarthritis was observed in two groups.
CONCLUSIONS:Autogenous osteochondral mosaicplasty and microfracture are proved to be safe and effective procedures for knee articular cartilage defects. However, the mosaicplasty has better clinical outcome than the microfracture.
