Yes, knee replacement is possible and effective even in a 55-year-old woman weighing over 90 kg, provided the surgery is properly planned and medical conditions are well controlled many patients experience significant pain relief and improved mobility, allowing them to resume daily activities and even work within 6â12 weeks, depending on the job type. Higher body weight can slightly increase stress on the implant, but it is not a contraindication for surgery. Fat removal is NOT required before knee replacement; however, gradual weight reduction before and after surgery improves outcomes and implant longevity. Post-surgery lifestyle changes, strengthening, and joint care are key to long-term success.
