Abstract EN

Introduction : total knee replacement (TKR) is the gold standard treatment for the osteoarthritic knee, however the decision to replace the patella or not is still controversial.

similarly, in the last decade prosthetic designs have become more “patella-friendly”.

Methods : data from 171 patients who underwent unilateral TKR between January 2016 and December 2016, at the Jordanian royal medical services centre, were retrospectively analysed using knee society scores (KSS), knee society functional scores (KSFS) and visual analogue scales (vas).

inclusion criteria required patients with degenerative osteoarthritis of the knee joint that had stopped responding to nonsurgical treatments.

exclusion criteria involved patients indicated for patellar replacement.

Results : the preoperative mean KSS in the patellar non-resurfacing (PNR) group (group a) was 29.2.

after three years, this score increased to 86.6.

in the patellar resurfacing (PR) group (group b), the score was 28.7 preoperatively, and after final follow-up three years later, this score increased to 86.4.

in group a ; KSFS was 25.8 preoperatively, and three years later, it was 87.9.

in group b, this score was 27.2 preoperatively, and 86.5 three years later.

vas data showed that the first three criteria; (1) sitting in a chair, (2) going up and down stairs (3) and getting out of bed, improved significantly after three years of follow-up, in both groups.

anterior knee pain showed improvements in both groups, but these improvements were significantly more improved in group a than group b during the first year of surgery.

Conclusions : after a three year follow-up, there were no differences between PR and PNR, in terms of KSS and KSFS improvements.

according to vas, anterior knee pain showed improvements in both groups, but these improvements were significantly more improved in group a than group b during the first year of surgery.

therefore, we recommend that patella replacement is unnecessary, unless absolute indications are provided.
