Summary

Total knee arthroplasty (TKA) can effectively treat neuropathic Charcot knee joints in patients without ataxia. Careful surgical techniques and component selection are crucial for successful long-term outcomes.

Area of Science:

  • Orthopedic Surgery
  • Neurology
  • Rheumatology

Background:

  • Neuropathic (Charcot) knee joint is a severe complication of tabes dorsalis.
  • Total knee arthroplasty (TKA) is a potential treatment option for end-stage Charcot joints.

Observation:

  • Three cases (5 joints) of neuropathic knee due to tabes dorsalis underwent TKA.
  • Patients were observed for over 8 years post-surgery.
  • No ataxia was present before or after surgical intervention.

Findings:

  • Satisfactory clinical outcomes and no loosening were observed in 3 joints over 9-10 years.
  • One case required revision arthroplasty due to tibial component loosening, but achieved satisfactory results.
  • Long-term TKA success is linked to meticulous surgical technique, ligament balancing, bone defect management, and the use of long-stem components.

Implications:

  • TKA is a viable and effective treatment for selected patients with neuropathic Charcot knee joints.
  • Adherence to specific surgical principles is essential for durable TKA results in this patient population.
  • Further research into optimizing TKA for neuropathic arthropathies is warranted.
