This paper reports the results of an experimental and finite element analysis of tibial screw fixation in hamstring ACL reconstruction. The mechanical properties of the bone and tendon graft are obtained from experiments using porcine/calf bones and tendon. The results of the numerical study are compared with those from mechanical testing. Analysis shows that the model may be used to establish ...

Greater hamstring musculotendinous stiffness is associated with lesser ACL loading mechanisms. Stiffness is enhanced via training, but previous investigations evaluated tendon rather than musculotendinous stiffness, and none involved the hamstrings. We evaluated the effects of isometric and isotonic training on hamstring stiffness and ACL loading mechanisms. Thirty-six healthy volunteers were r...

OBJECTIVES Surgical marking during tendon surgery is often used for technical and teaching purposes. This study investigates the effect of a gentian violet ink marker pen, a common surgical marker, on the viability of the tissue and cells of tendon. METHODS In vitro cell and tissue methods were used to test the viability of human hamstring explants and the migrating tenocytes in the presence ...

Tendon-bone incorporation of a tendon graft within the bone tunnel is a major concern when using a tendon graft for ligament reconstruction. Successful anterior cruciate ligament (ACL) reconstruction with a tendon graft requires solid healing of the tendon graft in the bone tunnels. Improvement of graft healing to bone is crucial to facilitate early and aggressive rehabilitation and a rapid ret...

Patellar Tendon (PT) rupture is an uncommon injury of the knee extensors. Majority PT ruptures occur at insertion site, on inferior pole patella as avulsion injury, mostly in males <40 years age and involving sports persons or accidental cases. A case series 10 cases neglected were managed with primary repair along augmentation semitendinosus gracilis (Hamstring tendons) graft. Patient follo...

Despite increased knowledge of hamstring muscle injuries, the incidence has not diminished. We now know that not all hamstring injuries are the same and that certain types of injuries require prolonged rehabilitation and return to play. The slow stretch type of injury and injuries involving the central tendon both require longer times to return to play. A number of factors have been proposed as...

[Purpose] This research explored the positive effects of self-myofascial release on hamstring muscular flexibility and proprioception and investigated the effectiveness of the stretch combined with therapeutic ultrasound. [Subjects and Methods] This study included 30 healthy university students with no history of pain in the Achilles tendon or hamstring within the recent 6 months. Each particip...
