Objective To analyze the related influencing factors of knee joint function in patients with tibial plateau fracture after surgery.Methods The 118 patients with tibial plateau fractures were treated with minimally invasive surgery under arthroscopy.HSS score was used to evaluate knee joint function.Multiple linear regression was used to analyze the influencing factors of knee joint function in patients with tibial plateau fracture after surgery.Spearman method was used to analyze the relationship between postoperative knee function and the incidence rate and severity degree of osteoarthritis Results Univariate analysis showed that there were statistically significant differences in HSS scores at 6 months after surgery among patients with different age,body mass index,Schatzker fracture classification,preoperative knee flexion-extension range,postoperative complications,knee extension device injury,tibial plateau pos-terior slope and fracture reduction quality(P<0.05).Multivariate analysis showed that overweight,Schatzker typeⅢ～Ⅳ,preoperative knee flexion-extension range≥90°,knee extension device injury,tibial plateau posterior slope>7°,age≥60 years,postoperative complications,and poor fracture reduction quality were the risk factors for knee func-tion after tibial plateau fracture(P<0.05).The incidence rate of osteoarthritis and WOMAC:HSS score≥70 points were lower than those with HSS score<70 points(P<0.05).Correlation analysis showed that HSS score of knee function after tibial plateau fracture was negatively correlated with the incidence and severity of osteoarthritis(P<0.001).Conclusions Overweight,Schatzker typeⅢ～Ⅳ,preoperative knee flexion-extension range≥90°,knee ex-tension device injury,tibial plateau posterior slope>7°,age≥60 years,postoperative complications and poor fracture reduction quality are risk factors for knee function after tibial plateau fracture.Targeted intervention measures can be developed to promote knee function recovery and reduces the risk of osteoarthritis.
