| Background: Knee osteoarthritis is a common disease that causes knee pain and dysfunction in middle-aged and elderly people,and is the main indication for knee replacement.For the treatment of severe knee arthritis,the most important method is to perform artificial knee replacement.According to statistics,about 5% to 20% of patients undergoing artificial total knee replacement only have severe knee joint single compartment.Degeneration.For patients who need knee replacement with only one compartment disease,knee joint replacement surgery has received extensive attention and application due to its many advantages such as less trauma,fast recovery,and good function.The surgical effect of single-sacral replacement was significantly improved compared with the early stage.For a long time,clinicians have reached a consensus on the importance of the TKA midline,but there are different views on the reconstruction of the lower limb line during UKA surgery.Objective: To analyze the relationship between lower limb force line and early clinical efficacy after knee joint osteoarthritis monoplasty(UKA)surgery.Methods: The patients who underwent single-sacral replacement surgery performed by the same surgeon from April 2016 to October 2019 in our department were followed up for a retrospective study.The KHA,ROM,and KSS scores before surgery were compared with those after surgery.Grouped according to the rating status,they were divided into a control group of varus 0 ~ 3 ° and a group of varus ≧3 °.SPSS software was used to test the correlation between the HKA and KSS scores and knee activity data of the affected limb after single ridge replacement.Results: 1.The KSS score of the patient improved from 60.0 ± 4.2 before surgery to 88.1 ± 5.7;the ROM at the last postoperative follow-up was 119.9 ± 5.6 °,which was significantly higher than 107.± 3.1 ° before surgery.The improvement from 172.9 ± 2.9 ° before surgery to 176.6 ± 1.9 ° after surgery.2.The average postoperative mobility of the 0 ~ 3 ° inversion group was 121.9 ± 5.4 °,and theaverage KSS score was 91.6 ± 3.2.Compared with this,the postoperative mobility of the 3 ° inversion group was 116.4.± 3.9 °,KSS score was 82.7 ± 3.8.After statistical analysis,the knee joint mobility and postoperative KSS score in the 0 ~ 3 ° varus group were higher than those in the 3 ° varus group,and the differences were statistically significant.Conclusions: 1.The knee joint mobility and KSS score of the postoperative patients were significantly improved compared with the preoperative ones,and the differences were statistically significant.2.The postoperative lower limb force line in the varus 0 ~ 3 ° group was higher in knee joint mobility and postoperative KSS score than the varus> 3 ° group.The difference was statistically significant.Try to correct it to be slightly smaller than the neutral position and avoid excessive varus deformity. |
