Study finds patient satisfaction is not affected by high flexion TKA

Researchers in this study found that patient satisfaction is not affected by increased knee flexion.
“As expected, the high-flex [total knee arthroplasty] TKA showed increased knee flexion, but no significant differences in the patient perceived outcomes were found,” Morten G. Thomsen, MD, and colleagues wrote in the study abstract. “This suggests little relevance to the patients of the difference in knee flexion – when flexion is of this magnitude – as pain free [range of motion] ROM and high patient satisfaction were achieved with both TKAs,”
Thomsen and colleagues analyzed the results of 36 patients who underwent bilateral TKA and randomly received either a cruciate-retaining implant or a high-flex posterior-stabilized implant in the contralateral knee.
After 1 year, the patients with the higher flexion knees reported no significant differences between either implant – the median VAS pain score was 0 points, the median VAS score was 9 points and the median VAS score regarding how a patient “felt” about his or her knee was 9 points, according to the abstract.
