HTO combined with abrasion and microfracture seen as effective for medial OA, varus malalignment

By Monica Jaramillo

High tibial osteotomy along with chondral resurfacing is efficacious for patients with severe medial osteoarthritis and varus malalignment, according to research with a minimum 5-year-follow-up.

Researchers prospectively surveyed 85 patients who underwent high tibial osteotomy along with chondral resurfacing procedures from September 2005 to December 2008. Minimum follow-up period was 5 years. Investigators used the IKDC questionnaire to evaluate patients’ function and survivorship was determined through telephone or postal questionnaires. Patients were also evaluated for clinical outcomes, radiographic results, the need for revision arthroscopy and cartilage regeneration at 1-year and 2-years follow-up.
