目的探讨成人大骨节病(KBD)患者膝关节骨赘大小与下肢力学轴线之间的相关性.方法对300例经临床确诊的成人KBD患者,运用数字化X线影像(DR)系统拍摄其1个膝关节前后位片(包括股骨远端1/2和胫骨近端1/2),并通过DICOM 2.0软件测量并计算骨赘长度、股骨胫骨角、胫股关节间隙比、骨赘突起指数,通过Pearson相关检验评价成人KBD患者膝关节骨赘突起指数和股骨胫骨角、胫股关节间隙比之间的相关性.结果 300个受检关节股骨胫骨角均值为(165.97±4.02)度,其与股骨内侧髁骨赘突起指数[(6.54±3.12)％]呈正相关[相关系数(r)=0.524,P＜0.01],与胫骨内侧平台骨赘突起指数[(7.14±3.40)％]呈正相关(r=0.578,P＜0.01).受检关节胫股关节间隙比为0.61±0.13,其与股骨内侧髁骨赘突起指数呈正相关(r=0.531,P＜0.01),与胫骨内侧平台骨赘突起指数呈正相关(r=0.563,P＜0.01).结论成人KBD患者膝关节股骨内侧髁和胫骨内侧平台骨赘大小与下肢力线之间有相关性,下肢生物力学的改变可能参与并介导了膝关节骨赘的生成和发展.

Objective To evaluate the correlation between osteophytes size and lower limb alignment in the knees of patients with Kaschin-Beck disease (KBD).Methods A total of 300 clinically diagnosed patients with KBD were X-rayed on knee-joints which ranged from the distal half of femur to proximal half of tibia.Meanwhile some related parameters in the X film with the anteroposterior position (including osteophytes length,femorotibial angle,femorotibial joint space ratio of inner side to outer side) were measured by DICOM 2.0,a software of medical graphic measuring,then followed by calculating the osteophyte spur index.The association between femorotibial angle,femorotibial joint space ratio and osteophytes spur index was evaluated by Pearson correlation test.Results The average of femorotibial angle of all the tested knee-joints was (165.97 ± 4.02)°,which positively correlated with both the osteophyte spur index of the medial femoral condyle [(6.54 ± 3.12)％,correlation coefficient (r) =0.524,P＜0.01] and the osteophyte spur index of medial tibil plateau [(7.14 ± 3.40)％,r =0.578,P ＜0.01].The femorotibial joint space ratio was 0.61 ± 0.13,which positively correlated with both the osteophyte spur index of medial femoral condyle (r =0.531,P ＜0.01) and that of the medial tibil plateau (r =0.563,P ＜0.01).Conclusions The results of this study indicate that there is a positive correlation between lower limb alignment and osteophyte size of both the medial femoral condyle and the medial tibial plateau.This finding may be evidenced by the fact that the changes of lower limb biomechanics may contribute to formation and development of osteophytes in the kneejoint.
