PURPOSE This study examined whether any fracture pattern shown in computed tomography (CT) scan is associated with the presence of lateral meniscus (LM) injury in a tibia plateau fracture. MATERIALS AND METHODS Fifty-three tibia plateau fractures with both preoperative CT and magnetic resonance imagings (MRI) available were reviewed. The patient demographics, including age, sex, body mass index, and energy level of injury were recorded. The fracture type according to the Schatzker classification, patterns including the lateral plateau depression (LPD), lateral plateau widening (LPW), fracture fragment location, and the number of columns involved were assessed from the CT scans. The presence of a LM injury was determined from the MRI. The differences in the factors between the patients with (Group 1) and without (Group 2) LM injuries were compared and the correlation between the factors and the presence of LM injury was analyzed. RESULTS The LM was injured in 23 cases (Group 1, 43.4%) and intact in 30 cases (Group 2, 56.6%). The LPD in Group 1 (average, 8.2 mm; range, 3.0–20.0 mm) and Group 2 (average, 3.8 mm; range, 1.4–12.1 mm) was significantly different (p < 0.001). The difference in LPW of Group 1 (average, 6.9 mm; range, 1.2–15.3 mm) and Group 2 (average, 4.8 mm; range, 1.4–9.4 mm) was not significant (p=0.097). The other fracture patterns or demographics were similar between in the two groups. Regression analysis revealed that an increased LPD (p=0.003, odds ratio [OR]=2.12) and LPW (p=0.048, OR=1.23) were significantly related to the presence of a LM tear. CONCLUSION LPD and LPW measured from the CT scans were associated with an increased risk of concomitant LM injury in tibia plateau fractures. If such fracture patterns exist, concomitant LM injury should be considered and an MRI may be beneficial for an accurate diagnosis and effective treatment.

PURPOSE To evaluate risk factors of posterolateral articular depression and characteristics of the posterolateral fragment in lateral condylar and bicondylar tibial plateau fractures with joint depression. MATERIALS AND METHODS We reviewed 48 patients of Schatzker type II and type V (type II 34, type V 14) and evaluated risk factors of posterolateral articular depression according to the posterolateral fragment, fibular fracture, and Schatzker classification. We evaluated the position of articular depression and anterolateral fracture line of the posterolateral fragment and measured anterior to posterior lengths of the posterolateral fragment. RESULTS Posterolateral articular depression was found in 20 of 34 cases (59%) with coexisting posterolateral fragment and in 16 of 21 cases (76%) with coexisting fibular fracture. There was a significant difference in the occurrence of posterolateral articular depression with the existence of the posterolateral fragment and fibular fracture (p<0.001). Multivariate regression analysis revealed that fibular fracture increased the occurrence of posterolateral articular depression (odds ratio 24.5, 95% confidence interval 2.2-267.2). Fifty-seven percentage of the anterolateral fracture line of the posterolateral fragment existed posterior to the anterior margin of the fibular head. CONCLUSION This study showed that fibular fracture affects posterolateral articular depression in Schatzker type II and V tibial plateau fractures. Selecting a fixation device and performing fracture reduction requires a careful consideration since the anterolateral fracture line of the posterolateral fragment exists posterior to the anterior margin of the fibular head.

PURPOSE To compare information about fracture type in MRI with simple radiograph in tibial plateau fractures and evaluate tibial plateau fractures type and accompanying soft tissue injury, and evaluate usefulness of MRI in tibial plateau fractures. MATERIALS AND METHODS Compared MRI with simple radiograph about Schatzker classification, depression of articular surface and displacement of bone fragment from the 68 examples who checked MRI and we evaluated soft tissue injury around knee joint. RESULTS There were 7 examples of Schatzker type change after MRI check. Average depression of articular surface in simple radiograph was 2.93 mm and 4.28 mm in MRI. It increased by 1.35 mm and it was meaningful statistically (p<0.05). There was no significant difference between MRI and simple radiograph of displaced bone fragment (p=0.168). There were 58 (85.3%) cases of soft tissue injury in MRI. CONCLUSION MRI can find additional fracture line or articular depression that can't be found in simple radiograph and gives more information about articular depression and soft tissue that is useful in surgical plans. I think preoperative MRI is necessary to better treatment of fracture & treatment of periarticular soft tissue injury in tibial plateau fracture.
