The histological effects of early mobilization in the healing after achilles tendon of rabbits rupture repair / 中国医师杂志

ABSTRACT

Objective To offer the histological proof of rabbits rupture repair after early mobilization.Method New zealand rabbits were random divided into 3 groups, including normal group, mobilization group (the experimental group) , and immobilization group.All rabbits' achilles tendons were inspected, and the histological difference were observed under light microscope and electron microscope respectively.Result The collagen fibers of the achilles tendons in the mobilization group under light microscope showed that it arrayed more regularly than in immobilization group.Fibroblasts were more maturate.The diameters of collagen fibrils under electron microscope in mobilization group were thicker[(8.417 ± 1.649)μm vs (6.818 ± 1.025)μm, t = 2.76, P ＜ 0.05] than immobilization group.The results showed statistical significance[(26.915 ±2.123)nm vs (21.725 ±3.768)nm, t =4.12, P ＜0.01].Conclusion Early mobilization after operation can promote the histological healing of achiles tendon.
