Snapping Hamstring Tendons Case Report: Tenotomy and Tendon Transposition.

CASE: A 14-year-old girl with a hypermobility syndrome presented with bilateral snapping semimembranosus (SM) and semitendinosus (ST) tendons. After failure of conservative treatment, she was treated with tenotomy of SM and later tendon transposition of her ST to her gracilis.

CONCLUSIONS

Surgical treatment of snapping hamstring tendons has historically consisted of the release of the tendon insertions (tenotomy) or tendon harvest. This new surgical technique describes an alternative technique for definitive management with tenotomy and tendon transposition where the snapping ST is transposed to the gracilis tendon to maintain hamstring muscle length, strength, and function.
