Summary
Restoring knee extension function improves quality of life for patients, especially older adults at risk of falls. Various reconstruction methods exist, with no age or comorbidity restrictions, offering tailored surgical options.
Area of Science:
- Orthopedic surgery
- Reconstructive surgery
Background:
- Functional knee extension loss significantly impacts patient quality of life, particularly in older adults prone to falls and secondary injuries.
- Instability and unsteady gait are common secondary consequences of impaired knee extension.
Purpose of the Study:
- To provide a comprehensive overview of knee extension reconstruction options.
- To offer a decision-making aid for operative indications based on lesion and patient characteristics.
Main Methods:
- Review of local reconstructions.
- Evaluation of functional tendon and nerve transfers.
- Assessment of free functional muscle transfers.
Main Results:
- Various reconstruction methods can improve quality of life for most patients.
- No general restrictions for reconstruction exist due to comorbidities or age.
- The study presents an overview of surgical options, postoperative procedures, and expected outcomes.
Conclusions:
- Functional reconstruction should be an integral part of interdisciplinary therapy for improving quality of life and preventing secondary complications.
- Therapeutic planning must extend beyond initial trauma or tumor control to include functional restoration.
