Adherence to the prescribed mobilization and protective protocol is the strongest factor shaping prognosis after a flexor tendon repair. Healing hinges on controlled loading that promotes tendon gliding while protecting the repair, so following the protocol ensures the repair is stressed appropriately to encourage proper collagen alignment and minimize adhesions. When patients remain compliant with the timing and limits of mobilization and protection, outcomes in range of motion and strength are generally better and rupture risk is reduced. While smoking can impair healing and age or occupation may influence overall recovery or functional demands, they do not impact the healing biology and protocol-driven outcome as powerfully as sticking to the prescribed post-op plan.
