Objective:To investigate whether knee osteoarthritis has an impact on the patient′s depression and whether it′s progression will affect the patient′s depression, and to provide a reference for clinical work.Methods:Patients diagnosed with osteoarthritis in Dalian Central Hospital from 2016 to 2019 were divided into 4 groups according to Kellgren-Lawrence staging, and the patients were scored on WOMAC scale, AKSS clinical scale, and AKSS. The score of the scale and the score of the HAMD scale were collected and statistically analyzed using SPSS 17.0.Results:χ2 test was used to show that there was no difference in the gender composition of patients in different stages ( P<0.05). The AKSS clinical scale score, AKSS functional scale score, WOMAC scale score and HAMD scale score were statistically analyzed for each stage. The results showed that the average AKSS clinical scores of patients in each stage were as follows: stage Ⅰ: (90.01 ± 8.41) points; stage Ⅱ: (79.98 ± 10.93) points; stage Ⅲ: (71.78 ± 13.64) points; stage Ⅳ: (54.18 ± 12.58) points. The AKSS functional scores were as follows, stage Ⅰ: 100 points; stage Ⅱ: 80 points; stage Ⅲ: 70 points; stage Ⅳ: 45 points; the average WOMAC scale scores of patients in each stage were as follows, stage Ⅰ: (28.69 ± 19.22) points ; stage Ⅱ: (49.43 ± 22.69) points; stage Ⅲ (70.13 ± 24.84) points; stage Ⅳ: (107.79 ± 24.39) points. The average HAMD scale scores of patients in each stage were as follows, stage Ⅰ: (4.89 ± 3.42) points; stage Ⅱ: (7.65 ± 4.20) points; Stage Ⅲ: (9.05 ± 5.03) points; stage Ⅳ: (12.35 ± 5.41) points. The analysis showed that there were significant statistical differences in the scale scores between each period ( P<0.05). There was a correlation between the patient′s depression status and the patient′s age, pain, and joint function, and there were statistical differences ( P<0.05). Conclusions:There is a significant correlation between depression and pain and function in patients with knee osteoarthritis. The progress of the osteoarthritis course will aggravate the patient′s depression state. Conversely, the patient′s depression state can also aggravate the symptoms of osteoarthritis patients and affect the clinical efficacy of the patients.
