Evaluation of the muscle atrophies occurring after open surgical tenotomy and percutaneous tenotomy

The trial was designed to compare the atrophies occurring after open surgical tenotomy and percutaneous tenotomy using the experimental model that we established. Fourty Ross-800 hybrid chickens were divided into two equal groups. The first and the second group underwent open surgical tenotomy and percutaneous tenotomy of the Achilles tendon, respectively. The animals were sacrificed after eight weeks, and the wet weight, volume, height, diameter, rate of biomechanical elongations and strength of muscles were measured by precision measurement instruments. H & E staining was performed for the histopathological assessment of muscles. In addition, the preparations were photographed and the rate of fatty infiltration and the muscles were assessed by the pixel counting method. All data were analyzed using the Mann-Whitney u test.
