The need for a dual rating system in total knee arthroplasty.

摘要: The sequential course of the knee score and functional Knee Society rating system 276 press fit condylar modular unconstrained total arthroplasties performed for osteoarthritis between June 1988 December 1992 was documented prospectively. increased significantly stayed on a constant level from 2 years on, whereas function reached maximum at declined subsequently. Multiple regression analysis testing statistical significance correlation preoperative predictors with criteria followup to determine their influence outcome. Preoperative were score, body mass index, age, gender, patient category, implant factors. Criteria studied pain, followup. is influenced by walking distance, category correlating moderately. not affected any these Pain found correlate low distance. Rating systems are numerous factors linked patient's general health condition. Their impact overall result can be controlled separate as dual does. Scoring adding up an should used. There need additional improvement arthroplasty such based evaluation establishing reliability validity.
