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 analyse the frequency of soft tissue injuries associated with tibial plateau fracture through arthoscopy and demonstrate the pattern and treatment of lateral meniscal tear which is the most frequently concomitant injury.
MATERIAL AND METHOD: We evaluated the charts, X-rays and arthoscopic records of the 27 patients who had been diagnosed as tibial plateau fracture and received the arthoscopic examination or arthoscopic assisted operative management and analysed the injury pattern, association of schatzker classification and treatment of the 9 patients who had been concomitant with lateral meniscal tear. RESULT In our cases, lateral meniscus tear was the most common among the soft tissue injury it was revealed that a longitudinal tear at the peripheral area was shown in 8 cases, which were treated with meniscal repair and a radial tear of the central area in l cases, treated with partial menisectomy. CONCLUSION Lateral meniscus injury is one of the most frequently concomitant with tibial plateau fracture, In those cases, arthroscopic meniscal repair would be helpful for better prognosis.
