ObjectiveTo explore the influencing factors of secondary osteoarthritis (OA) after operation of tibial plateau fracture.
MethodsSeventy nine patients with tibial plateau fracture treated with operation were selected and divided into secondary OA group (n=17) and non-secondary OA group(n=62).The risk factors of secondary OA to surgical treatment of tibial plateau fracture were analyzed by single factor and logistic regression analysis.
ResultsThere were no significant difference in gender, age, fracture classification (Schatzker type), degree of injury violence, smoking and drinking history, operation time, bleeding volume, bone grafting and total hospitalization days (P>0.05)between the two groups, but there was significant difference in perioperative days (P < 0.05).Regression analysis showed that perioperative period of more than 7 days was a risk factor for secondary OA.
ConclusionsThe duration of perioperative period can indirectly reflect the energy absorption intensity of fracture, the destruction of soft tissue, and the effect of perioperative symptomatic treatment.It is an important influencing factor of postoperative secondary OA.
