Abstract

High load is concentrated on Satba wearing area of Ssireum athletes during the tournament. Muscular injuries in this area may seriously affect the athletic performance. We report a case of a 21-year-old Ssireum athlete who was experiencing pain in his left thigh (Satba wearing area) during a tournament due to the migrating mass effect of a partial ruptured semitendinosus muscle occurred approximately 6 months before. Herein is described the clinical results after surgical intervention with an added review of the relevant literature.

  Figure 1 (A) Initial magnetic resonance imaging (MRI) finding shows ovoid mass-like lesion (arrow) at proximal semitendinosus muscle with high signal intensity on T2 coronal image surrounding soft tissue edema. (B) 6 months follow-up, MRI finding shows down sized ovoid mass having well defined margin (arrow) at the same site with high signal intensity on T2 coronal image.

  Figure 2 (A) Torn end of semitendinosus muscle was exposed and excised between normal muscle and fibrous portion. (B) The muscle is extensively replaced by dilated vascular channels with thrombosis and mature adipose tissue (H&E stain, ×40).

• 

  Figure 3 Schematic figure representing of the mechanism of injury. Note that eccentric contraction of hamstring muscle results from sudden knee extension and hip flexion of the pivoting lower extremity (curved arrow) in condition of adding excessive stress at Satba wearing area (straight arrow).
