Clinical, radiographic, bone scan and arthroscopic evaluation of osteoarthritis of the varus knee being considered for high tibial osteotomy

ABSTRACT

28 knees with varus osteoarthritis, in 25 patients were studied. They were 13 men and 12 women, mean age 52.1 years. In comparison arthroscopy offered the more effective assessment modality, as it detected early articular cartilage changes. This was followed by radioisotope bone scanning as it revealed early subchondral osseous changes. Radiography demonstrated later changes. Clinical assessment was effective as regards physical signs and subjective data
