Effect of Placing Drainage or Not on Rapid Rehabilitation after Primary Total Knee Arthroplasty / 中国康复理论与实践

Objective:To explore the effect of placing drainage or not on rapid rehabilitation after total knee arthroplasty (TKA). Methods:From January, 2018 to September, 2020, 80 patients with knee osteoarthritis who underwent primary TKA in our hospital were analyzed retrospectively, and they were divided into groups A and B, with 40 cases in each group. Drainage was placed routinely in group A and not in group B. The postoperative serum inflammatory factors, postoperative pain score, postoperative complication rate, postoperative time out of bed, hospital stay, knee function score, range of motion of knee and World Health Organization Quality Of Life-abbreviated version score (WHOQOL-BREF) were compared between two groups. Results:There was no significant difference in the levels of C-reactive protein between two groups on the 1st to 3rd day after operation (t < 0.410, P > 0.05). There was no significant difference in Visual Analogue Score between two groups from 12 h to 48 h after operation (t < 0.300, P > 0.05). The incidences of postoperative complications were 5.0% in group A and 2.5% in group B, with no significant difference between two groups (χ2 = 0.346, P > 0.05). The time of getting out of bed and hospital stay was significantly shorter in group B than in group A (t > 4.863, P < 0.001). The scores of knee joint function, range of motion of knee and WHOQOL-BREF significantly increased after operation in both groups (t > 6.099, P < 0.001), however, there was no significant difference between two groups (P > 0.05). Conclusion:Placement or non-placement of drainage after primary TKA does not affect postoperative complications, knee joint function and quality of life of patients with knee osteoarthritis, however, non-placement of drainage can promote postoperative recovery and discharge.

Correlation of Social-psychological Health and Joint Function in Patients during Rehabilitation for Joint Impairment / 中国康复理论与实践

Objective:To explore the influence of social-psychological factors on outcome of joint rehabilitation. Methods:From October, 2015 to April, 2017, 64 inpatients accepting joint rehabilitation were divided into anxiety group and non-anxiety group, and depression group and non-depression group, according to the scores of Hamilton Anxiety Scale and Hamilton Depression Scale. They were assessed with routine joint scores as initial and final stages of joint rehabilitation, as well as Symptom Checklist-90 (SCL-90) and World Health Organization Disability Assessment Schedule 2.0 (WHO-DAS 2.0). The correlation of joint scores to scores of SCL-90 and WHO-DAS 2.0 was analyzed with Spearman correlation analysis. Results:There were significant differences in joint scores between the depression and the non-depression groups initially and finally (|t| > 2.106, P < 0.05). The joint score at the initial stage was negatively correlated with the interpersonal factor score of SCL-90 (r = -0.257, P < 0.05). The joint score at the final stage was negatively correlated (P < 0.05) with the dimension one (r = -0.257) and four (r = -0.278) of WHO-DAS 2.0, total score (r = -0.263), and interpersonal (r = -0.328) and hostile (r = -0.385) factor scores of SCL-90. Improvement of joint score negative correlated with dimension one of WHO-DAS 2.0 score (r = -0.249, P < 0.05). Conclusion:The social-psychological factors affect the outcome of joint rehabilitation. It is necessary to explore the way to take the the social-psychological assessment into the routine three stage evaluation of the joint rehabilitation protocol.
