The regional clinic performed 187 knee replacement procedures on osteoarthritis (OA) patients. Materials were randomly selected for morphological analysis from 30 patients, 11 of whom were men and 19 of whom were women, ages 40 to 76. Of the thirty individuals that underwent morphological investigations, three (10%) had stage I OA; eight (26.7%) had stage II OA identified, and nineteen (63.3%) had stage III OA. Just one in four patients (48 individuals, or 25.7%) who received endoprosthetics had at least one round of inpatient conservative or minimally invasive surgical therapy for OA. The morphological research revealed that 11 (36.7%) of the patients who received arthroplasty had validated stage I–II OA. The conclusion is that in order to create a treatment plan for patients with osteoarthritis (OA), an algorithm for coordinating specialists' interactions must be developed. This algorithm should involve therapists, orthopedists, rheumatologists, rehabilitologists, specialists in restorative medicine, and health care coordinators.
