Abstract

A numerical rating system was designed as a method of evaluating results of extensor mechanism reconstructions of the knee. The method was applied in evaluating the long-term results of patients treated at one orthopaedic clinic. A paramount goal was to maintain objectivity in evaluations of patients kneesafter reconstruction. Parameters of evaluations were swelling, pain, symptoms of instability, and limitations of activity. Each factor was rated on a scale of zero to three. Results were separated into four categories (excellent, good, fair and poor). Weighted consideration was given to each parameter in relationship to others. The presentation of the rating system and the criteriafor definitions of the terms excellent and good form the intent of this paper,not the reporting of results. As one gains experience in these examinations, subjectivity will be minimized. A universally applicable scale, such as presented in this design, is one way investigators may compare results obtained by any surgical technique. Furthermore, the strict criteria can be applied preoperatively and post-operatively so that the results can be placed in perspective. The numerical rating system provides a standard for evaluation of results obtained from extensor mechanism reconstructions of the knee. Verf.-Referat
