Comparison of pain, femoral and tibial mechanical oct angles, knee joint position and physical performance in patients with early and late stage gonarthrosis

This study was conducted to compare pain, femur and tibia mechanical axle angles, knee joint position sensation and physical performance in patients with early and late stage gonarthrosis. The study included 56 individuals diagnosed with gonarthrosis according to the American Society of Rheumatology (ACR) diagnostic criteria. The patients were classified into two groups as early stage 28 and late stage 28 based on Kellgren-Lawrence criteria. After the demographic information of the patients was obtained, the pain severity was determined using the Numerical Pain Scale (NAS), medial proximal tibial angle (MPTA) and lateral distal femoral angle (LDFA) from the mechanical axis angles of the femur and tibia via orthorhontgenography of the lower extremities, knee joint position feeling was determined as the target angle using a Baseline digital goniometer with an active angle repetition test of 15°, 30°, 45° and 60°, and physical performance was performed for 30 seconds he was evaluated with the get up and sit test, stair climbing test and timed get up and walk test. According to the knee radiographic staging of the patients participating in the study, the average age of the early-stage patients was 54,5±5,43 years, the average height was 169,4±9,19 cm, the average weight was 77,1±12,12 kg, and the average BMI was 26,7±2,66 kg/m2. The mean age of late-stage patients was 67,1±4,40 years, the mean height was 166,2±9.08 cm, the mean weight was 80,4 ±7,96 kg, and the mean BMI was 29,2±2,48 kg/m2. Between the pain severity of patients with early stage gonarthrosis and the pain severity of patients with late stage gonarthrosis, between the affected side MPTA and LDFA values of patients with early stage gonarthrosis and the affected side MPTA and LDFA values of patients with late stage gonarthrosis patients with early stage gonarthrosis, between the values of MPTA and LDFA of the affected side of patients with early stage gonarthrosis and the values of MPTA and LDFA of the affected side of patients with late stage gonarthrosis, between the values of MPTA and LDFA of the other side of patients with early stage gonarthrosis and the values of MPTA and LDFA of the other side of patients with late stage gonarthrosis, between the knee joint position feeling of patients with early stage gonarthrosis 15°, 30° and 45° and the knee joint position feeling of patients with late stage gonarthrosis 15°, 30° and 45° a statistically significant difference was found (p<0,05). However, there was no significant difference between the 60° knee joint position feeling of patients with early stage gonarthrosis and the 60° knee joint position feeling of patients with late stage gonarthrosis (p>0,05). Statisticallysignificant differences were found between the 30 sec sit-up test, stair Deceleration test and timed get up and walk test of patients with early stage gonarthrosis and the 30 sec sit up test, stair deceleration test and timed get up and walk test of patients with late stage gonarthrosis (p<0,05). As a result, in patients with gonarthrosis in this study, it was found that pain severity increased in the later stages of the disease, MPTA and LDFA values were negatively affected, knee joint position sensation losses could be experienced, and physical performance scores were negatively affected. For this reason, it is thought that physiotherapy and rehabilitation programs that will be applied from the first time gonarthrosis diagnosed individuals receive the diagnosis may be protective in nature and prevent the progression of the disease.
