The Balanced Knee® System: 3 to 6 Year Outcomes and Survivorship

The authors evaluate the clinical outcomes of patients who underwent a total knee arthroplasty with the Balanced Knee® System (BKS®) with at least 3-year follow-up. A retrospective chart review was performed of 335 patients who had TKR with BKS implants and had a minimum follow-up of 3 years. Radiographic and clinical outcomes were analyzed for preoperative, 6-week, 1-year, 4-year and final follow-up. Reoperation for any reason was recorded, and Kaplan-Meier survivorship was analyzed. Overall outcomes for this system were good. Knee Injury and Osteoarthritis Outcome Score for Joint Replacement and Patient Reported Outcomes Measurement Information System physical and mental scores improved significantly. There were nine (2.6%) revisions for any reason during the study period. Kaplan-Meier survivorship was 96% at 5 years. BKS is a modern total knee implant that offers patients excellent patient reported and radiographic outcomes at short to mid-term follow-up.
