Ligament Healing
The repair process for damaged ligament tissue, similar to but distinct from tendon healing. Ligaments connect bone to bone and have variable healing capacity depending on location. Some ligaments (like the ACL) have poor intrinsic healing ability, driving interest in peptide-based regenerative approaches.
Technical Context
Ligament healing biology parallels tendon healing but with important differences: the ACL (anterior cruciate ligament) heals poorly after rupture due to its intra-articular location (surrounded by synovial fluid that dilutes haematoma growth factors and prevents organised clot formation), while extra-articular ligaments like the MCL (medial collateral ligament) heal more successfully because they are surrounded by vascularised tissue that supports a healing response. MCL healing produces functionally adequate scar tissue in 6-12 weeks with conservative management; ACL rupture typically requires surgical reconstruction. Ligament healing research models: MCL transection in rodents (common model because it heals predictably), ACL transection (less commonly used for healing studies — more often for instability models). Any peptide claiming ligament healing properties should be evaluated in the specific ligament model relevant to the clinical application.
