The causes of unsatisfactory results and mistakes in treatment of patients with pigmented villo-nodular synovitis (teno-synovial giant-cell tumor) of a knee joint

Abstract

Objective. To reveal the causes of unsatisfactory results and mistakes in treatment of patients with pigmented villo-nodular synovitis of a knee joint with the objective to improve this disease diagnosis, as well as the results of treatment and rehabilitation/ Materials and methods. Through the period 2010 - 2018 yrs we conducted a retrospective analysis of medical documents (the case histories) in 77 patients with pathohistologically verified diagnosis of pigmented villo-nodular synovitis of a knee joint, who were treated in the clinic of Institute of Traumatology and Orthopedics (ITO), Kyiv and operated on a knee joint. Results. The causes of unsatisfacory results of treatment for pigmented villo-nodular synovitis of a knee joint are the disease severity, and its diffuse form, absence of the diagnosis-treatment algorithm for this process and rehabilitation of the patients, what leads to diagnostic and tactical mistakes on the treatment process stages. Conclusion. The awaiting tactics in diagnosis and treatment of pigmented villo-nodular synovitis constitutes a wide-spread tactical mistake. Insufficient knowledge of traumatologists in a knee joint surgery leads to tactical faults as well. Most treatment mistakes occur as a consequence of unreadiness of orthopedist-traumatologist for possible intraoperative accidental revealing of pigmented villo-nodular synovitis of a knee joint, as well as because of absence of intraoperative tactics and material gears for treatment of this disease and its outcomes.
