RESUMO
To observe the therapeutic effects of segmental resection and decompression combined with joint prosthesis on continuous knee osteoarthritis [OA]. A total of 130 patients with knee OA were selected and randomly divided into an observation group and a control group [n=65]. The control group was treated by segmental resection in combination with joint prosthesis, and the observation group was treated by segmental resection and decompression combined with joint prosthesis. They were followed-up for three months. All patients underwent successful surgeries during which no severe complications occurred. During the follow-up period, the overall effective rates of the observation group and the control group were 93.8% and 78.5% respectively, which were not statistically significantly different [p < 0.05]. The observation group was significantly less prone to patellar instability, infection and deep vein thrombosis compared with the control group [P < 0.05]. On the same day after surgery, the knee joint scores and functional scores of the two groups were similar, which evidently increased three months later, with significant intra-group and inter-group differences [p < 0.05]. Combining segmental resection and decompression with joint prosthesis gave rise to satisfactory short-term prognosis by effectively improving the flexion and extension of injured knee and by decreasing complications, thus being worthy of promotion in clinical practice
