Balanced Flexion and Extension Gaps Are Not Always of Equal Size
2018, Journal of ArthroplastyCitation Excerpt :Special PS trials were created for the study that could replicate an FC up to 2 sizes larger than the femoral preparation, accounting for differences of bone resection thickness. With each trial, we measured the knee flexion angle in passive extension with the leg supine, and the maximum passive flexion angle and internal tibial rotation with the femur held vertical and the extensor mechanism reduced [14]. The associations of posterior tibial translation and predicted flexion gap artifact with average laxity change (adjusted as described previously) between fittings with PS and CR trials were described using simple linear regressions and Pearson's correlation coefficients.

2015, Journal of ArthroplastyCitation Excerpt :When the release was obviously more than 50%, it was recorded as greater than 50%. The individual patient's potential knee flexion was documented by intra-operative examination of flexion against gravity after implantation and capsular closure [17]. Group analysis was separated into patients with fixed bearing TKAs and patients with mobile bearing TKAs.
Does flexion of the femoral implant in total knee arthroplasty increase knee flexion: A randomised controlled trial
2014, KneeCitation Excerpt :A further difference between the two studies was the addition of the intra-operative evaluation point in our study. Assessment at this time allows a measure of knee flexion without the confounding influence of pain, swelling and psychosocial factors [27,31] providing a more direct evaluation of a surgical technique or implant design. The improvement in knee flexion seen in the flexed group at the intra-operative time point (Fig. 4) demonstrated that flexing the femoral implant appears to provide an immediate benefit of increased knee flexion when compared to the neutral orientation.
