Osteoarthritis in the lateral compartment of the knee joint is more common in middle-aged and elderly patients. Symptoms include pain, swelling, snapping, stiffness, and joint effusion. At present, there are many ways to treat osteoarthritis in the lateral compartment of the knee joint, and most people adopt conservative treatment. However, for patients with more serious conditions, conservative treatment cannot achieve obvious results, but surgical treatment is required. However, surgical treatment often causes psychological stress on patients, especially elderly patients. Therefore, the study focused on the occurrence and prevention of psychological diseases in patients with lateral knee osteoarthritis after postoperative care programs including psychological treatment.

A total of 110 patients with osteoarthritis in the lateral compartment of the knee admitted to a hospital from July 2020 to January 2022 were selected as the research objects. The enrolled patients were randomly divided into two groups, the control group and the observation group, with 55 cases in each group. In the control group, there were 29 males and 26 females, aged 37-79 years, with an average of (60.22 ± 14.15) years old. In the observation group, there were 32 males and 23 females, aged from 35 to 80 years old, with an average of (60.83 ± 14.34) years old. There was no significant difference in general data between the two groups (P > 0.05), which were comparable. The control group was given routine postoperative care, and the observation group was given experimental nursing program including psychotherapy.

From the perspective of coping style, there was no significant difference (P > 0.05) in the scores of positive and negative coping styles between the two groups before nursing. After nursing, the positive coping style of the observation group was higher than that of the control group (P < 0.05), and the score of negative coping style was lower than that of the control group (P < 0.05). In terms of anxiety and depression scores, there was no significant difference in SAS (Self-Rating Anxiety Scale) and SDS (Self-Rating Depression Scale) scores between the two groups (P > 0.05). After nursing, the SAS and SDS scores of the observation group were significantly lower than those of the control group (P < 0.05), as shown in Table 1.Table 1.

Comparison of SAS and SDS scores before and after group care

The coping style and psychological state of patients with osteoarthritis in the lateral compartment of the knee have a greater impact on postoperative recovery, and individualized nursing including psychotherapy can help improve their coping style and psychological state.
