High tibial osteotomy for knee arthritis can lead to neurological issues. Some patients developed foot deformities and nerve damage, particularly affecting the posterior tibial and deep peroneal nerves after surgery for varus alignment.

Area of Science:

  • Orthopedic Surgery
  • Neurology
  • Biomedical Engineering

Background:

  • High tibial osteotomy (HTO) is a common surgical procedure for treating knee osteoarthritis.
  • Monocompartmental arthritis, particularly in the knee, often necessitates HTO to correct alignment.
  • Neurological complications following orthopedic surgery are a concern for patient outcomes.

Purpose of the Study:

  • To investigate the incidence of neurological impairment after high tibial osteotomy.
  • To identify specific neurological deficits and associated foot deformities post-HTO.
  • To correlate surgical indications, such as varus malalignment, with neurological sequelae.

Main Methods:

  • Retrospective review of 100 patients who underwent high tibial osteotomy for monocompartmental knee arthritis.

  • Clinical assessment for neurological impairment and pes planus deformity.
  • Electromyographic (EMG) studies to evaluate nerve function.

    • Main Results:

    • 15% of patients (15 out of 100) showed evidence of neurological impairment post-HTO.
    • Four patients developed severe symptomatic pes planus deformity in the operated limb.
    • EMG confirmed posterior tibial nerve dysfunction in all 4 patients with pes planus, and deep peroneal nerve damage in 3.

    Conclusions:

    • High tibial osteotomy may be associated with a risk of neurological impairment, including nerve damage.
    • Pes planus deformity can be a presenting symptom of neurological dysfunction after HTO.
    • Varus malalignment as an indication for HTO may be linked to these neurological complications.
