Objective:

To evaluate the effect of artificial dermal composite grafting on postoperative joint function and scar recovery in patients with joint scar contracture.

Approach:

• Study Design: Retrospective study including 130 patients with joint scar contracture, divided into control (65 patients) and intervention groups (65 patients).
• Data Analysis: Univariate analysis for baseline characteristics, multivariate logistic regression for recontracture rates, and generalized estimating equations (GEE) for joint function and scar score.

Key Findings:

• One-year postoperative recontracture rate was significantly lower in the intervention group (6.15%) compared to the control group (32.31%) (P < 0.001).
• Intervention group showed significantly greater improvements in active range of motion (A-ROM) and passive range of motion (P-ROM) at 3 and 12 months postoperatively (P < 0.05).
• Significant improvement in Vancouver Scar Scale (VSS) scores at 1, 3, and 12 months postoperatively in the intervention group (P < 0.01).
• Patient satisfaction was significantly higher in the intervention group at all follow-up time points.

Interpretation:

Artificial dermal composite grafting significantly reduces the incidence of scar recontracture and improves joint range of motion and scar appearance during long-term follow-up.

Limitations:

• Retrospective design may introduce selection bias.
• Limited generalizability due to single-center study.

Conclusion:

Artificial dermal composite grafting provides a treatment option that addresses both function and aesthetics for patients with scar contracture.
