Calculating position of joint line of knee using various radiological parameters based on Indian population
Journal Title: International Journal of Orthopaedics Sciences - Year 2017, Vol 3, Issue 3
Abstract
Restoration of the joint line of the knee is an important technical goal of a total knee arthroplasty. Failure to restore the joint line of the knee to anatomical position can lead to mid-flexion instability, a reduction in range of motion, impingement of the patellar tendon against the tibial tray, and gap imbalance. The presence and integrity of bone and soft tissue landmarks makes restoration of the joint line Successful. Restoration of the joint line both difficult and unreliable especially in revision TKA, where the necessary landmarks are often missing or obscured. Numerous methods, ranging from relative references, to absolute distances have been described for joint line restoration, yet a lack of consensus remains. The aim this study was to determine a reproducible, quantitative relationship between position of joint line and identifiable anatomical landmarks in Indian population after studying randomly selected Indian population. Results of our study indicate that Femoral diameters are statistically different for Sexes while Tibial diameters are not, IMD is 1.75 times LFJL,CTD is 2.7 times PTFJL, PCO is more important in predicting range of motion in TKA. PCJL:FD and IED:LEJL are also significant.
