The Effect of Patella Eversion on Clinical Outcome Measures in Simultaneous Bilateral Total Knee Arthroplasty: A Prospective Randomized Controlled Trial.
BACKGROUND During total knee arthroplasty ( TKA ) , surgical exposure requires mobilization technique of the patella . With this trial , we intended to investigate the effect of patella eversion on clinical outcome measures in simultaneous bilateral TKA . METHODS We prospect ively enrolled 44 patients ( 88 knees ) from April 2008 to June 20l4.One knee was operated with patella eversion  ( group A ) and the other with patella lateral retraction  ( group B ) r and omly . Follow-up results , including the operation time , complications , and the time of achieving straight leg raise ( SLR ) and 90 ° knee flexion , were recorded . The data of range of motion ( ROM ) and Visual Analogue Scale score were collected separately at 7 days , 3 months , 6 months , and 1 year postoperatively . RESULTS The time of achieving SLR was 2.7 ± 0.8 days in group A and 2.1 ± 0.7 DAYS in group B , which were significantly different ( P = .032 ) . Significant difference was found on active and passive ROM during the follow-up times between groups A and B , except the passive ROM at 6 months postoperatively . No significant difference was found on operation time , complications , patella baja or tilt , time of achieving 90 ° knee flexion , and Visual Analogue Scale score during the follow-up times . CONCLUSIONS Patellar eversion was adverse to the early knee function recovery after TKA ; it would delay the time of achieving SLR and decrease the passive and active ROM . In addition , more carefully and scientifically design ed r and omized controlled trials are still required to further prove the cl aim
