Objective: To compare the efficacy of single condylar joint replacement and total knee arthroplasty in the treatment of knee osteoarthritis. Methods: Sixty patients with single knee osteoarthritis of the knee were selected in our hospital from June 2015 to December 2017. All the patients were treated with unilateral knee joint lesions. The patients were randomly divided into the control group and the observation group, 30 cases in each. The control group was treated with total knee arthroplasty, while the observation group was treated with single condyle joint replacement. The patient's intraoperative and postoperative conditions were recorded in detail, such as the amount of intraoperative bleeding, the decrease of hemoglobin three days after operation and the time required for autonomic flexion to 90°, and the knee flexion, HSS score, KSS clinical score and KSS function score. Results: Compared with the two groups of patients during and after the operation, the amount of bleeding in the observation group, the decrease of hemoglobin three days after operation and the time of independent flexion to 90 degrees were significantly lower than those in the control group, the difference was statistically significant (P<0.05). Before operation, there was no significant difference in the knee flexion degree and HSS score between the two groups (P>0.05). After the operation, the knee flexion degree, the HSS score and the knee flexion degree of the two groups were superior to those before the operation, but the knee flexion degree and the HSS score of the observation group were significantly better than those in the control group, the difference was statistically significant (P<0.05). The clinical score and KSS function score of the observation group were significantly higher than those of the control group (KSS <0.05). The difference was statistically significant (P<0.05). The two groups of patients had different degrees of pain before operation. The pain condition of the two groups was significantly relieved after operation, but there was no significant difference in the excellent and good rate (P>0.05). Conclusion: Single condylar arthroplasty can effectively reduce the wound, reduce the amount of bleeding, significantly improve the clinical score of KSS, KSS function score and HSS score, which is worthy of clinical reference. |
