Total knee arthroplasty and posterior tibial slope
Keywords:
Range of motion, Posterior tibial slope, Total knee arthroplastyAbstract
Background:Total knee arthroplasty has been considered as a standard procedure for intractable pain in the end-stage degenerative arthritis of the knee and maintaining range of motion (ROM) to facilitate the ability to perform daily living activities. A majority of studies have reported that the influence of PTS on the range of motion, however controversy exists.
Methods: Two hundred patients (400 knees) who underwent simultaneous or staged bilateral knee replacements and who met our inclusion criteria were included for this study. The pre-operative and post-operative knee ROM and PTS were recorded for each patient. Patients followed up at regular interval with minimum follow up of one year.
Results:200 patients that is, 400 knees who underwent posteriorly stabilised TKA were considered. Respective mean ROM and PTS were 1060 and 7.80 preoperatively and 1280 and 5.70 postoperatively. We divided the patients in to group A (post-operative PTS ≤80) 346 knees, and group B (postoperative PTS >80) 54 knees and analysed the relation between PTS and ROM.
Conclusions:Change in PTS does not have influence on postoperative ROM in posteriorly stabilised TKA. Preoperative range of motion has got significant effect on post op range of motion following TKA.
