Dynamics of Quality of Life Indicators in Patients with Chronic Synovitis of the Knee Joint after Arthroscopic Laser Double-mode Synovectomy

Abstract

Background: The treatment of patients with chronic synovitis of the knee joint is a challenge faced by many doctors all around the world. Treatment of this pathology is often a difficult task.
 Aim. The aim of the study was improving the results of treatment of patients with chronic synovitis of the knee joint by applying two wavelengths of radiation.
 Material and methods. The treatment results of 50 patients with chronic synovitis of the knee joint aged 23 to 67 years with stage II-IV osteoarthritis according to the Kellgren-Lawrence classification were analyzed. All patients underwent arthroscopic sanation, partial laser synovectomy using LSP-IRE-Polus apparatus, wavelength 0,97 microns in pulse-periodic mode (pulse 100 ms, pause 50 ms) with power 5 W and wavelength 1,56 microns in continuous mode with power 5 W. Morphological examination of the synovial membrane and capsule was performed. Preoperative, 3, 6 and 12 month postoperative questionnaires were administered using the following scales and questionnaires: VAS, Leken index, WOMAC and KOOS.
 Results. Mean age (M) was 45.32±131, BMI 28.63±4.72kg/m2, duration of synovitis 2.26±1.91 years. A statistically significant improvement on the VAS, WOMAC, Leken, KOOS scales was noted by the 3rd month of postoperative follow-up. By the 6th month postoperatively, the results had further improved. The achieved results were preserved up to 12 months after surgery (P <0.05).
 Conclusion. The results suggest that the proposed technique may be introduced into clinical practice.
