Correlation of Posterior Tibial Slope with Metaphysio-diaphyseal Angle in Total Knee Arthroplasty: A Radiological Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 8
Abstract
Background: Posterior tibial slope (PTS) is an important factor affecting post-operative range of motion following total knee arthroplasty (TKA). Metaphysio-diaphyseal angle (MDA) is a new entity defined as the angle between proximal anatomical axis and metaphyseal axis of tibia. This study was undertaken to determine PTS in Indian patients and find its correlation with MDA of tibia. The accuracy of extramedullary jigs and the influence of MDA on the accuracy was also evaluated. Materials and Methods: Data of 100 consecutive patients undergoing TKA in a single center by a single surgeon were analyzed. Posterior cruciate ligament substituting TKA was done with the same jig to achieve different PTS in different patients. MDA, pre-operative PTS, and post-operative PTS were calculated. The data were analyzed using appropriate statistical analysis. Results: Mean pre-operative PTS was 11.64° and mean MDA was 23.76° with a strong correlation between them (Pearson’s coefficient 0.72). Extramedullary jigs were accurate in 53% of cases. In remaining 47%, post-operative PTS was less than planned PTS in 30%, and more in 17%. Mean post-operative PTS was 2.54°. In patients with MDA < 20°, post-operative PTS was significantly less (P = 0.0176) compared with those with MDA > 20°. Conclusions: The study establishes the positive correlation between MDA and PTS in Indians; and that MDA is an independent factor affecting the accuracy of extramedullary jigs in TKA.
