Hydrogel Adhesion Performance Data for Cartilage and Bone Repair

A supplementary document details biomechanical and adhesive performance tests for a photo-curable phosphoserine-functionalized methacrylated gelatin hydrogel. The data includes adhesion strength measurements on human cartilage, subchondral, and cancellous bone, comparing results to fibrin glue and assessing effects of sterilization and hydration. Author Peyman Karami published the document under a CC-BY-4.0 license on figshare in May 2026.

Use Cases

• Compare hydrogel adhesion strength to fibrin glue based on ex vivo tensile adhesion data on human tissues.
• Analyze the impact of polymer content and sterilization protocols on mechanical performance based on described formulation tests.
• Evaluate the effect of surface hydration on adhesion strength based on experiments under dry and wet conditions.
• Identify optimal formulation windows for clinical application based on combined injectability, adhesion, and defect confinement results.

Strengths

• Adhesion strength values are provided for three human tissue types: cartilage (68.3 ± 12.5 kPa), subchondral bone (44 ± 5.5 kPa), and cancellous bone (31.2 ± 8.2 kPa).
• The description identifies a clinically relevant formulation window of 15–20 wt% polymer content based on systematic testing.
• The dataset is openly available under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document (589.7 KB), which may require parsing to extract structured data.
