comparative clinical and cost analysis between surgical and non-surgical intervention for knee osteoarthritiis
solmaris [256]

To assess the treatment options and costs for osteoarthritis of the knee (OAK), a condition that affects the knee joint and progresses over time owing to cartilage and bone deterioration.

Methods: Over the course of two years, we prospectively examined the clinical results and quantified cumulative direct expenses of patients with OAK sent to our multidisciplinary OA programme.

A total of 133 patients were evaluated. All showed radiographic signs consistent with moderate to severe OAK. We tracked and examined changes in the Western Ontario McMaster Osteoarthritis Index (WOMAC), Minimal Clinically Important Improvement (MCII), and BMI.

The total direct expenditures for all subjects' medical and surgical care during a two-year period were calculated.
