The influence of preoperative deformity on valgus correction angle: an analysis of 503 total knee arthroplasties.

We prospectively studied variations in valgus correction angle (VCA) and the influence of preoperative limb deformity on VCA in 503 consecutive total knee arthroplasties done in 393 patients. The percentage of limbs that had VCA values less than 5° was 10.9%, and that with VCA values greater than 7° was 44.

Simultaneous bilateral versus unilateral computer-assisted total knee arthroplasty: a prospective comparison of early postoperative pain and functional recovery.

Whether simultaneous bilateral TKAs (SBTKAs) are more painful and the postoperative functional recovery slower compared to staged bilateral TKAs or unilateral TKAs are issues that frequently concerns patients. The purpose of the current study was to compare the early postoperative pain, function and recovery in simultaneous bilateral versus unilateral computer-assisted TKA. In this prospective study, 50 consecutive patients undergoing unilateral computer-assisted total knee arthroplasties (TKAs) were compared with 50 consecutive patients undergoing SBTKAs in terms of pain, length of hospital stay and rehabilitative milestones during the immediate postoperative period.
