Socio-demographic and anthropometric data, comorbidities and characteristics of the gonarthrosis were recorded. The primary endpoint was quality of life, assessed by the knee osteoarthritis-specific quality of life questionnaire: Arthrosis of the Lower Limbs and Quality of Life (AMIQUAL).The Knee injury and Osteoarthritis Outcome Score-Physical Function Short form (KOOS-PS) was used as a tool to assess the functional impact of gonarthrosis.
