BACKGROUND: Joint scar contracture often leads to joint dysfunction, appearance deformity, and severe decline in patients' quality of life. This study aimed to evaluate the effect of artificial dermal composite grafting on postoperative joint function and scar recovery in patients with scar contracture.
METHODS: This study retrospectively included 130 patients with joint scar contracture, who were divided into a control group (n = 65) and an intervention group (n = 65) according to the surgical method. Univariate analysis was used to compare baseline characteristics, perioperative indicators, and recontracture rates between the two groups. Three multivariate logistic regression models were constructed to analyze the effects of treatment method and baseline characteristics on the occurrence of recontracture. Generalized estimating equations (GEE) were used to analyze the effects of treatment method, follow-up time (postoperative 1 month, 3 months, and 12 months), and their interaction on active range of motion (A-ROM), passive range of motion (P-ROM), and scar score (Vancouver Scar Scale, VSS). Finally, the differences in patient satisfaction between the two groups at different postoperative follow-up time points were analyzed.
RESULTS: There were no significant differences in baseline characteristics between the control and intervention groups. The one-year postoperative recontracture rate was significantly lower in the intervention group than in the control group (6.15% vs. 32.31%, P < 0.001). All three multivariate models consistently identified the intervention as an independent protective factor against postoperative recontracture. GEE analysis showed that the intervention group achieved significantly greater improvements in A-ROM and P-ROM at 3 months and 12 months postoperatively compared with the control group (P < 0.05), and significantly better improvement in VSS at 1 month, 3 months, and 12 months postoperatively (P < 0.01), indicating significant improvements in scar appearance, pliability, and texture. Patient satisfaction in the intervention group was also significantly higher than that in the control group at 1 month, 3 months, and 12 months postoperatively.
CONCLUSION: Artificial dermal composite grafting can significantly reduce the incidence of scar recontracture and markedly improve joint range of motion and scar appearance during long-term postoperative follow-up, providing a treatment option that addresses both function and aesthetics for patients with scar contracture.
