Fits of the SHR (blue), GOH (green), and FR (red) models to experimental tensile test data [mean (open symbols) ± SE (bar)] for the murine patellar tendons. Top row (aging): a mature, b aging, and c aged. Bottom row (age-dependent healing): d mature, e aging, and f aged. , , and . Models exhibited reasonable fits to the experimental data. A decline with age in the ultimate tensile strength of the tendons is observable from the top row
