Hallux valgus (HV) violates the musculoskeletal function of the lower limb, and also affect the x-ray anatomical parameters of the foot. There is the study of the most important correlations between age, morphological and functional changes of the forefoot play a big role in the choice of treatment tactics for this pathology. The aim was to analyze the age, functional and radiological results of surgical treatment of Hallux valgus deformity of the first toe using the methods saving the metatarsophalangeal joint. 126 patients had Hallux valgus deformity of the first toe of I, II, III degree. They were examined before surgery, then 3, 6 and 12 months after operation. 126 patients were operated according to the method of Scarf, Austin, Bosch-Magnan osteotomy. X-ray results were assessed by the Hallux valgus angle (HVA), the intermetatarsal angle (IMA), the distal metatarsal articular angle (DMMA) before and after the operations. AOFAS rating scale (Kitaoka) and biomechanical (stabilometric) study were used for the functional assessment of the surgical treatment results. The IMA correction angle after operation increases with the patient's age. HVA becomes the most deformed angle in the pathology of Hallux valgus with increasing age before osteotomy. The best functional result according to the AOFAS scale was obtained with the greatest correction of the IMA angle after osteotomy. The functional index of the foot decreased with increasing age after osteotomies.

Degenerative pathology of the musculoskeletal system is one of the main reasons for decreased mobility in patients of the older age group. Increasing the life expectancy leads to predominance non-epidemic pathology in all developed countries. Therefore, degenerative diseases of musculoskeletal system have not only medical significance but also social significance. Objective is studying the morphological features of synovial environment of the decompensated osteoarthritic (OA) knee joint. Structural features of subchondral bone, hyaline cartilage of the femur and tibia, the articular capsule, menisci and ligamentous apparatus of the knee joint were studied in 64 patients who underwent total knee arthroplasty at the Department of Traumatology and Orthopedics Bashkirian State Medical University in the period from 2015 to 2020. Material selection, preparation of histological samples, staining with hematoxylin-eosin, microscopy was performed. Adaptive signs of articular cartilage of the femoral condyles manifest in the form of cartilage tissue rearrangement, which are most pronounced in the central zone of the cartilage. At the same time, the phenomena of decompensation and significant areas of destruction are noted. Also, the subchondral bone was replaced with connective tissue with subsequent sclerosis. This sclerosis subsequently led to the decompensation of structures of the hyaline cartilage in the deep and middle zones. Destructive and dystrophic processes were noted in the knee joint menisci. Articular cartilage was replaced with granulation tissue with subsequent invasion of blood vessels. Cruciate ligaments in patients with OA show signs of adaptation due to expansion of endothenonium layers between bundles of collagen fibers and an increase in the diameter of blood vessels.
