significant weight loss may delay or eliminate the need for total knee replacement

a 48‑year‑old morbidly obese woman with a left medial meniscal tear and moderately severe degenerative joint disease (djd) reported for 14‑month follow‑up visit from arthroscopic surgery. she reported a resolution of pain, swelling and an improved range of motion (rom). the patient was first evaluated 14 months ago, and at that time was considered a strong candidate for total knee replacement due to her limited (rom), knee pain, swelling and functional impairment. at a 3 month visit prior to her initial evaluation the patient voluntarily enrolled in a nutritional and exercise program overseen by a licensed personal trainer and kinesiologist. at her final evaluation 14 months later, it was noted that in addition to her improved knee symptoms, the patient lost 15% of her initial bodyweight and exhibited significant gains in quadriceps strength. her clinical exam and imaging suggested an arrest of progression of her joint disease. it was decided mutually by the patient and physician that she was no longer a candidate for total knee replacement surgery. although the association between her weight loss and her knee djd can only be hypothesized, this case report may highlight the need to discuss weight loss as an alternative treatment modality for end stage djd.
