“…There are advantages in using the ST tendon such us ease harvesting during surgery, suitable morphology as ACL graft and lower donor-site morbidity 1 . After harvesting for ACL reconstruction, the hamstring tendon regenerates in most people and becomes similar to normal 2,3 . Many studies have been published on the anatomy and the composition of the regenerated tendons using MRI scans, ultrasonography and CT scans [4][5][6] .…”

“…Morphological changes including atrophy 4 and shortening 7 of the ST muscle belly have been confirmed in patients with ACL reconstruction using the ST tendon. Further, the tendon undergoes morphological changes such as regeneration and hypertrophy 2,4,5,[8][9][10] up to 32 months after surgery. In addition, ST muscle volume decreases by an average of 30% and appeared to correlate well with the degree of tendon regeneration after ACL reconstruction 7 .…”

SummaryBackground: The most widely used graft as a replacement in anterior cruciate ligament (ACL) reconstruction is the semitendinosus (ST) tendon graft. After harvesting for ACL reconstruction, the hamstring tendon regenerates in most people and becomes similar to normal. The effect of graft harvest on muscle morphology and function remains unclear. The present study aimed to examine the morphology of the ST during isometric contraction after harvesting the ST tendon for ACL reconstruction. Methods: Maximal isometric contractions of the knee flexors from two angular positions were performed by 8 participants, at least 1 year after ACL reconstruction with an ST tendon graft and 8 matched controls. Ultrasonographic images were used to measure the pennation angle and muscle thickness of the ST muscle. Results: There was not a statistically significant difference in pennation angle values between the control group and the group who underwent ACL reconstruction (p >0.05). Muscle thickness was significantly higher in the ACLR group compared with controls (p< 0.05). Conclusions: Individuals who underwent ACL reconstruction display a higher ST muscle thickness but similar pennation angle compared with controls. This indicates that ACL reconstruction has an effect on ST muscle belly but effect on force generation capacity is rather limited. Level of evidence: IIb.

“…13,29 Study conducted by Cross et al demonstrated apparent regeneration of the tendons of the semitendinosus and gracilis muscles after their use for anterior cruciate ligament reconstruction. 30 Also the results demonstrated that these tendons appear to regrow and are probably functional. There is no loss of hamstring strength in our series when it is used as a graft material which corresponds to study conducted by Lipscomb AB 31 who demonstrated that there is no significant loss of hamstring strength occurred when the semitendinosus and gracilis tendons were used to construct the ACL.…”

Background: With increase participation in sports activities, anterior cruciate ligament (ACL) tear is a common and functionally disabling injury. Hamstring tendon as autografts for arthroscopic ACL reconstructions have shown good clinical and functional outcome in patients. The purpose of present study was to compare the functional outcome of arthroscopic Anterior Cruciate ligament (ACL) reconstruction using single bundle six fold and four fold ST and G graft.Methods: This was a prospective study conducted between period June 2008 to December 2010.181 patients undergoing ACL reconstruction were screened and 113 patients fulfilling the inclusion exclusion criteria were selected for the study.Results: All patients completed a minimum of 1 years follow up. In 4 fold group 27.50% were having grade 1 anterior drawer test 22.50% were having grade 1 Lachman test and 17.50% had grade 1 pivot shift test as compared to 6 fold group 6.66% had grade 1 anterior drawer test, 11.66% had grade 1 Lachman test, and 3.33% had grade 1 pivot shift test respectively which was statistically significant (p<0.05). Conclusions: Arthroscopic ACL reconstruction using six fold graft is effective modality of treatment in patient with ACL deficient knee. Six fold graft is thicker in diameter and cross sectional area as compared to four fold graft which occupies more surface area of normal ACL foot print and gives better stability of knee joint in both AP and rotational plane.

“…Other studies with MRI 40,41 have shown reconstitution of the semitendinosus and gracilis tendons, often with a more proximal attachment. They did not show hypertrophy of the semimembranosus or biceps femoris muscles.…”
