Total knee arthroplasty in patient with paraplegia after spinal cord injury.

The clinical management of paraplegic patients is more complex than in able-bodied subjects. Spinal cord injury (SCI) affects younger, active people more often than the elderly during high-energy fall or traffic accidents. In order to return to work after suffering an SCI, patients need to regain their functional independence, especially their ability to drive. The literature lacks strong evidence addressing the surgical solutions in severe knee arthrosis in paralyzed patients after SCI. We present a favourable outcome of total knee arthroplasty (TKA) of a stiff knee in extension in a man with T12 grade C paraplegia after SCI. We describe an effective rehabilitation protocol after knee arthroplasty in patient with damage to the spinal cord. Several factors should be taken into account before performing surgery: 1. ability of regaining some of spinal cord locomotor function through intensive gait rehabilitation in SCI patients, 2. presence of muscle imbalance and knee contractures combined with a risk of bone fracture resulting from intensive postoperative rehabilitation, 3. the impaired microvasculature of the skin and subcutaneous tissues and increased risk of occlusion occurrence of the capillaries and small vessels of the leg, 4. higher prevalence of secondary infections via urinary entry sites in patients after SCI, 5. patient's strong determination and willingness to undergo the arthroplasty procedure. TKA might be considered in selected paralyzed patients after SCI, especially in those with severe arthrosis as well as significant knee contractures. Our study reveals the advantage of performing TKA in improving functional state in patients with cord injury.
