To determine the prevalence of atraumatic lateral collateral ligament complex (LCLC) abnormalities by magnetic resonance imaging (MRI) in patients with osteoarthrosis (OA) of the knee.
Magnetic resonance imaging scans in 96 subjects (25 with OA and 71 without OA) were retrospectively reviewed for the presence and severity of LCLC signal abnormalities. Abnormalities in the MRI scans of subjects with OA were compared with those of subjects without OA using chi2 test and the Mantel-Haenszel test for trend.
Lateral compartment OA (23 of 25) was associated with abnormalities of the LCLC in 96% (22 of 23 subjects had fibular collateral ligament abnormalities, P < 0.0001). Medial compartment OA (25 of 25) was associated with abnormalities of the LCLC in 88% (22 of 25 subjects had fibular collateral ligament abnormalities, P < 0.0001). There was a positive trend for severity of MRI abnormalities with severity of OA (P < 0.0001 to P = 0.04).
Lateral collateral ligament complex MRI signal abnormalities are common in patients with OA, in the absence of trauma.
通过磁共振成像（MRI）确定膝关节骨关节炎（OA）患者非创伤性外侧副韧带复合体（LCLC）异常的患病率。
回顾性分析96名受试者（25名OA患者和71名非OA患者）的磁共振成像扫描结果，以确定LCLC信号异常的存在及严重程度。使用卡方检验和Mantel-Haenszel趋势检验，比较OA患者与非OA患者MRI扫描中的异常情况。
外侧间室OA（25例中的23例）与LCLC异常相关，发生率为96%（23例中有22例腓侧副韧带异常，P < 0.0001）。内侧间室OA（25例中的25例）与LCLC异常相关，发生率为88%（25例中有22例腓侧副韧带异常，P < 0.0001）。MRI异常的严重程度与OA的严重程度呈正相关趋势（P < 0.0001至P = 0.04）。
在无创伤的情况下，OA患者中LCLC的MRI信号异常很常见。
