Purpose In staged bilateral total knee arthroplasty (TKA), regaining functional recovery and a painless joint with fulfilment of patients’ expectations at the first stage is an integral part for a patient to progress to the second stage. As patient expectations drive postoperative satisfaction, the challenge is to match patient and surgeon expectations before surgery. Therefore, this study aimed to evaluate the postoperative patient expectations and clinical outcomes and to evaluate the rate of second stage in bilateral staged TKA.
Methods The study included 111 patients; 81 females and 30 males with a median age at surgery of 68 years (range 59–85 years) and 46 were older than 70 years. Postoperative functional data included Knee Society Scores (KSS).
Total Knee Arthroplasty (TKA) is the treatment of choice for patients with end-stage knee osteoarthritis [1, 2]. TKA for bilateral gonarthrosis can be performed either by simultaneous one stage or in two stages. Whether bilateral TKA should be staged or simultaneous is a heated debate [3].
