Summary: Full thickness QT grafts with bone exhibited similar material properties to BTB and 4-SST grafts, while Partial thickness QT graft without bone had significantly lower material properties than BTB and 4-SST. The RF graft demonstrated significantly lower material properties compared to BTB and 4-SST grafts.

Summary: This study compared the effects of quadrupled semitendinosus tendon (ST) and doubled semitendinosus tendon and gracilis tendon (ST/G) grafts on patients undergoing anterior cruciate ligament reconstruction (ACLR) over a 4.5-year period. The results showed that female patients who underwent ACLR with a quadrupled ST graft had significantly increased anterior tibial translation, inferior functional results, and higher pain scores. However, in male patients, using either graft option for ACLR showed comparable results with no significant impact on donor site morbidity.

Summary: This study aimed to determine the differences in the proportions of type I and type III collagen in the ST, QT, and PT, which are commonly used as autografts for ACL reconstruction. Results showed that the QT and PT had higher percentages of type I collagen, while the ST had a higher percentage of type III collagen. The use of ST for ACL reconstruction in physically immature patients may be associated with high re-injury rates.

Summary: The study showed that adipose-derived stem cell (ADSC) sheets can improve biomechanical strength of autografts used in ACL reconstruction, leading to better tendon-bone interface healing and graft midsubstance healing in a rabbit model.

Summary: Anatomical reconstruction of the coracoclavicular and acromioclavicular ligaments using a semitendinosus tendon graft for chronic acromioclavicular joint dislocation treatment showed good clinical and radiographic outcomes at a minimum 2-year follow-up. Time to surgery was found to be independently associated with poorer functional scores. Approximately 13.3% of patients exhibited partial loss of reduction on radiographs.

Summary: The study found that semitendinosus graft harvest may reduce knee joint isokinetic flexion strength in the short term, but full recovery is achieved by 12 months, with minimal impact on the donor site and little to no reported pain by most patients.

Summary: A retrospective study showed that dual semitendinosus allograft reconstruction is an effective option for chronic Achilles tendon ruptures, providing good clinical outcomes and low rerupture rate.

Summary: This study evaluated the age-related changes in cellular and microstructural properties of the semitendinosus muscle tendon in humans. The shape of tendon cell nuclei became more elongated with age, and the number of tendon cells decreased. The mean fibril diameter of the tendon decreased with age, and the distribution of collagen fibrils changed from right skewed to flat.

Summary: This study assessed the force and power exertion during a countermovement jump after ACL reconstruction using different grafts. It found that both bone-patellar tendon-bone and semitendinosus and gracilis participants showed asymmetries in force exertion, with the bone-patellar tendon-bone group showing greater asymmetries and higher peak power.

Summary: The feasibility of using ultrasonography to predict the autologous hamstring graft diameter for ACL reconstruction in the Zhuang population was evaluated in this study. The measurements were obtained from two levels of the tendons, and the correlation between ultrasonic and intraoperative measurements was analyzed. The study found that preoperative ultrasound can be used to predict the sufficient diameter of autografts, with measurements obtained at the widest point of the medial femoral epicondyle being the most reliable.

Summary: The quadriceps tendon (QT) autograft shows comparable graft survival, clinical function, and pain outcomes to bone-patellar tendon-bone (BPTB) and hamstring tendon (HT) autografts in ACL reconstruction. However, donor site morbidity is significantly higher with the QT autograft compared to BPTB and HT autografts.

Summary: This study compared the viscoelastic and failure properties of two hamstring graft configurations, with the results showing that the 2 configuration had superior performance in stress relaxation, dynamic creep, and maximum failure load compared to the Z configuration. These findings support the use of folding techniques for tripled grafts to improve their properties and reduce suture interfaces.

Summary: In this meta-analysis, the use of the QT autograft was found to be equivalent to the HT autograft in ACL reconstruction, with similar rates of graft failure and clinical and functional outcomes observed. However, HT autografts were associated with better knee extensor strength symmetry.

Summary: The study found that ACL reconstruction surgery using ST tendon autograft may significantly influence hamstring muscle function, leading to an increase in relative BF activity and a decrease in relative ST activity. These changes in hamstring muscle activation pattern may have implications for athletic performance and injury risk.
