- place the leg in a figure of 4 position;
- make a small longitudinal incision opposite the tibial tuberlce, midway between the tubercle and the the posterior edge of the tibia;
- palpate the pes anserinus
- generally only the gracilis and semitendinosus will be felt, since the sartorius thins out well proximal to its insertion;
- attempt to identify the saphenous nerve;
- make an incision directly over and in line with the gracilis tendon;
- open the tendon sheath and release adhesions and fibrous extensions that attach to the sheath;
- pes anserinus
is exposed through a short verticel incision;
tendons are harvested proximally w/ appropriately sized tendon stripper; (Brand type tendon stripper);
- residual muscle is removed;
- semiT should be placed in a moistened sponge, but is not be submerged in saline, since this may cause tendon swelling;
- paratenon surrounding the semitendinosus should be preserved;
- careful to avoid saphenous nerve

- fate of the harverst site:
- in report by Eriksson K, et al
, authors evaluated fate of the semiT muscle, after ACL reconstruction;
- the study included were 16 consecutive patients;
- ACL reconstruction was performed with a quadruple semitendinosus tendon graft using the EndoButton technique;
- of the patients, 75% showed regeneration of their semitendinosus tendons;
- neotendons all inserted below knee joint where they had fused with gracilis tendon to a conjoined tendon inserting in the pes anserinus;
- semitendinosus muscle had a smaller cross-sectional area on the operated side but none showed total atrophy;
- isokinetic strength of the hamstrings and quadriceps was significantly lower in the operated leg than in the nonoperated leg.
- in the report by Ferretti A, et al
, the authors describe the histologic course of regenerated tissue simulating the semitendinosus tendon in three patients after anterior cruciate ligament reconstruction with doubled semitendinosus and gracilis tendons;
- specimens were retrieved during revision surgery for removal of tibial hardware at 6, 24, and 27 months, respectively;
- resisted flexion during physical examination in all patients revealed a "string" on the posteromedial aspect of the knee that was quite evident, suggesting the presence of a regenerated semitendinosus tendon;
- well-defined fibrous band was identified about 3 cm proximal and medial to the pes anserinus, reproducing the pathway of the native semitendinosus tendon;
- in both of the specimens retrieved 2 years postoperatively, all of the central, thicker portion of each specimen was occupied by well-oriented tendon-like fibers together with uniformly distributed spindle-shaped cells that had appearance of mature tenocytes arranged in orderly rows;
