New Study Shows Effects of BMI on Knee Meniscus Surgery

11 Jan 2018 entries, news

A study recently published in The Journal of Arthroscopic and Related Surgery shows that among normal-weight and obese patients, there is no significant difference in clinical outcomes after arthroscopic partial meniscectomy (surgery to meniscus in the knee). The study was published by UBMD Orthopaedics & Sports Medicine physicians, Dr. Leslie BissonDr. Geoffrey BernasDr. Marc Fineberg,  Dr. John Marzo, Dr. Michael Rauh, and Dr. William Wind. They found that while obese patients (BMI > 30) had worse pain and function scores before surgery, compared with normal-weight patients (BMI < 25), after 1 year of surgery, there were no statistically significant differences in outcomes. However, obesity was associated with decreased knee flexion after surgery (bending at the knee joint).

Dr. Bisson was recently interviewed for Healio Orthopaedics Today, in which he stated that “Secondary analysis of data from the Chondral Lesions and Meniscal Procedures (CHAMP) Randomized Trial, which excluded subjects with radiographic evidence of knee [degenerative joint disease] DJD, found that overweight and obese patients had similar outcomes to those with normal BMI after arthroscopic meniscectomy.” These results enable orthopaedic surgeons to feel confident in the short term that their patients’ body weight won’t affect outcomes.
