Abstract：Objective To investigate the distribution of bone contusions in the knee joint after acute anterior cruciate ligament(ACL)rupture following non-contact sports injuries.Methods A total of 186 patients who underwent ligament reconstruction surgery for complete anterior cruciate ligament rupture were selected from the General Hospital of the Northern Theater Command from January 2023 to May 2024,After excluding the criteria,101 patients remained.There were 100 males and 1 female,aged(25.96±4.61)years old,ranging from 18 to 37 years old.The presence of bone contusions in the lateral tibial plateau(LTP),medial tibial plateau(MTP),lateral femoral condyle(LFC),and medial femoral condyle(MFC)was recorded separately.Bone contusions in LTP,LFC or both were defined as lateral bone contusions,and bone contusions in MTP,MFC or both were defined as medial bone contusions,and the relationship between the location and severity of bone contusions was compared.Results Among the 101 cases,had one contusion were 9 cases(LTP were 5 cases,MFC were 2 cases,LFC was 1 cases,and MTP was 1 case),had two contusions were 42 cases(LTP+LFC were 33 cases,LTP+MTP were 7 cases,and LFC+MTP were 2 cases),had three contusions were 34 cases(LTP+LFC+MTP were 25 cases,LTP+LFC+MFC were 6 cases,and LTP+MFC+MTP were 3 cases),and had four contusions were 16 cases(LTP+LFC+MTP+MFC were 16 cases).The proportion of lateral bone contusions[97.0％(98/101)]was higher than that of medial bone contusions[61.4％(62/101)],the difference was statistically significant(P＜0.05).The severity of bone injuries on the inner and outer sides of the knee joint also showed a statistically significant difference(P＜0.05).Conclusion Lateral bone contusions are more common and more severe than medial in patients with non-contact anterior cruciate ligament rupture.
