Evaluation Of Relationship Between Femoro-Tibial Angle And Meniscus Injury

Abstract

OBJECTIVE:The purpose of this study was to assess the relationship between the presence of meniscal injury and the femorotibial angle in the knee joint.METHODS:Patients who underwent knee magnetic resonance imaging (MRI) at our department between January 2015 and March 2015 were included in this study. Knee MR images of these patients were retrospectively re-evaluated for meniscal injury. The anatomic femorotibial angle measurements of the patients were calculated using AP knee radiograms. The relationship between femorotibial angle values and the presence of meniscal injury was analyzed.RESULTS:One hundred and fourteen knee joints of 101 patients were included. The mean age of the patients was 40.6±13.4 years. The number of injured medial menisci was 92 and the average femorotibial angle in these knees was 5.6±1.88; the number of non-injured medial menisci was 22 and the average femorotibial angle value in these knees was 5.8±1.92 (p=0.82); The number of lateral meniscus with injury was 22 and the mean femorotibial angle value in these knees was 6.1±1.50; the number of lateral meniscus without injury was 92 and the average femorotibial angle value in these knees was 5.6±1.96 (p=0.20).CONCLUSION:In our study, there was no statistically significant correlation between femorotibial angle values and the presence of injury in medial and lateral meniscuses. We believe that frontal plane bone alignment disorder of the knee does not have a predisposition to meniscal injury.

Assessment of the Relationship Between the Femorotibial Angle and Meniscal Injury with Radiologic Imaging Methods

“…This was not statistically significant (p>0.01). Sirik (3) reported that the mean FTA value was 6.1±1.50°C in the knee joints with a LM injury and 5.6±1.96°C in the normal knee joints. This was not statistically significant (p=0.20).…”

“…MRI is the most accurate and least invasive method for diagnosing meniscal lesions. In addition, soft tissues, articular cartilage, tendon injuries, and ligaments can be evaluated better with an MRI than with other imaging methods (1,3). A normal meniscus is seen as a triangular-shaped low intensity signal on T1-and T2-weighted sequences or on FSE sequences (1).…”

“…Because the posterior horn of the MM absorbs most of the weight of the medial compartment, a posterior horn MM tear is common. Lateral meniscal tears are more common in the younger population and frequently occur secondary to acute trauma (1,3). The criteria of the meniscal tears diagnosing with MRI include either an increased intrasubstance signal unequivocally contacting the articular surface or meniscal distortion in the absence of prior surgery.…”

“…Degenerative arthritis may occur when the stress increases on the articular cartilage (1). The load is unproportionally transmitted to the medial compartment of the knee during walking (3). Malalignment is an important biomechanical factor in the progression of knee osteoarthritis (OA) (4).…”

Unicompartmental knee arthroplasty versus high tibial osteotomy for medial knee osteoarthritis: A systematic review and meta-analysis

“…1 Medial KOA may result from knee alignment disorders or injuries that damages the cartilage and overloads the medial tibiofemoral compartment. 2 Knee malalignment has been suggested as an important biomechanical risk factor in KOA progression and declines in physical function. 3,4 Both high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are most frequently used medial KOA joint surgeries.…”
