background anterior cruciate ligament (acl) injury is the most common sports injury in both athletes and nonathletes; it can cause disability if not treated correctly. in cases with minor injuries, conservative treatments suffice. but, in cases with acl tear, surgery by different methods and autografts are indicated. the most prevalent method for acl reconstruction is the use of hamstring tendo...

Chronic patellar tendon ruptures are a difficult clinical problem. Treatment options include repair and augmentation with hamstring tendons and other grafts. We describe a technique of extensor mechanism reconstruction using an allograft consisting of quadriceps tendon, a patellar bone block, patellar tendon, and a tibial bone block. This technique is a salvage procedure indicated only in the m...

Background Previous studies have associated anthropometric data and pre-operative hamstring tendon measurements to intraoperative graft diameter for hamstring autograft ACL reconstruction, although an integrated model has yet to be described. The aim of this study was to present such a predictive model for quadrupled semitendinosus (4-ST) and doubled semitendinosus-gracilis (4-STG) graft constr...

The laryngeal mask airway (LMA) is a supraglottic medical device used to maintain a patent airway during surgery or a medical emergency. Its initial use was as a means of providing general anesthesia without an endotracheal tube (ETT) while avoiding the need to hold an anesthesia mask in place. As clinical experience has developed with the device, the LMA has been used for a wider range of surg...

OBJECTIVES The objective of this study was to determine if the use of fascia lata as a tendon regeneration guide (placed into the tendon canal following harvesting the semitendinosus tendon) would improve the incidence of tissue regeneration and prevent fatty degeneration of the semitendinosus muscle. MATERIALS AND METHODS Bilateral semitendinosus tendons were harvested from rabbits using a t...

After anterior cruciate ligament (ACL) reconstruction, which muscle groups are more affected from frequently developing thigh muscle atrophy is a matter of debate. We evaluate the effect of thigh circumference difference between patients' knees who were administered the ACL reconstruction with hamstring tendon autograft and intact knees, on torque between the hamstring and quadriceps muscles. F...

Hamstring injury has been considered one of the most common exercise-induced injuries in sports. mostly occur proximal to biceps femoris. However, reasons and mechanisms remain unclear. To summarize hamstring morphological structure features what relationship is between their risk from current literature, this review discussed possible mechanism hamstrings, connected pattern diversity, mechanic...
