Both exercise alone and combined exercise/diet interventions significantly improve knee pain, disability, and physical performance in older adults with knee osteoarthritis, with no significant between-group differences in pain scores.
Starting an exercise program is beneficial for reducing knee pain and improving function in older adults with osteoarthritis, regardless of whether they lose weight. You do not need to lose weight to get pain relief from exercise, although losing weight may offer additional biomechanical benefits.
GoodQualifiesMEDIUM confidence
Significant improvements were noted in both groups in self-reported disability and knee pain intensity and frequency as well as in physical performance measures. However, no statistical differences were found between the two groups at 6 months in knee pain scores or self-reported performance measures of physical function.
Why this rating
Randomized clinical trial, small sample size.

- A combined dietary and exercise intervention produces significant weight loss (mean 18.8 lb) in older obese adults with knee osteoarthritis, whereas exercise alone yields minimal weight loss (4.0 lb).Good
- Combined exercise and diet intervention improves specific gait biomechanics (loading rate and maximum braking force) more than exercise alone in older adults with knee osteoarthritis.Good

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
