Total Knee Replacement in Young Patients
Patient Selection Criteria
- The American College of Rheumatology recommends that young patients with advanced osteoarthritis undergo total knee replacement when conservative treatments have failed, with consideration of realistic expectations, higher revision rates, and the likelihood of needing future revision surgery given their longer life expectancy 1
- Young patients must have radiographic evidence of moderate-to-severe osteoarthritis with documented joint damage, and must have completed at least one trial of appropriate nonoperative therapy including physical therapy, NSAIDs, and/or intraarticular injections without improvement 1
- The American College of Rheumatology suggests that symptom severity, including moderate-to-severe pain or significant functional limitation, should be considered when selecting patients for total knee replacement 1
- Shared decision-making between the patient and surgeon is essential in establishing the indication for total knee replacement 1
Expected Outcomes and Survival Rates
- The evidence shows that 89% of young patients achieve good or excellent outcomes for pain and function up to 5 years after total knee replacement, according to the American Academy of Orthopaedic Surgeons 2
Revision Risk and Complications
- The American College of Rheumatology and the American Association of Hip and Knee Surgeons conditionally recommend proceeding with total knee replacement without arbitrary 3-month delays once criteria are met, as patients have already attempted prolonged conservative treatment 1
Technical Considerations
- Preoperative imaging, including standing AP and lateral radiographs plus full-length hip-to-ankle views for alignment assessment, is essential for total knee replacement in young patients, as recommended by the Orthopaedic Society 3
- Postoperative management, including early mobilization and supervised exercise programs during the first 2 months, can improve physical function in young patients after total knee replacement, according to the American Academy of Orthopaedic Surgeons 3
Common Pitfalls to Avoid
- The American College of Rheumatology recommends that patients be educated about increased surgical complications associated with obesity, poor glycemic control, and nicotine use, though lack of resources to modify these should not be an absolute contraindication for total knee replacement 1
