Estimation of Diameter of Quadrupled Hamstring Graft for ACL Reconstruction using Pre-operative MRI Measurement as a Predictive Tool [PDF]

Malaysian Orthopaedic Journal
Introduction: The diameter of the quadrupled Hamstring graft plays a significant role in the incidence of graft failures for ACL reconstruction. The ability to predict the graft size pre-operatively can prepare the surgeon for alternatives in the event ...

High‐grade trochlear dysplasia increases patellofemoral joint pressure and decreases the knee extension torque, and tibial tubercle anteriorisation does not correct these effects: Biomechanical study in vitro

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose High‐grade femoral trochlear dysplasia is associated with anterior knee pain, patellar maltracking, instability and the development of osteoarthritis. Scientific studies have signified the importance of trochlear resection on the knee extensor mechanism, and dysplasia can be addressed by a groove‐deepening trochleoplasty. Alternatively,

Larger interface area at the human myotendinous junction in type 1 compared with type 2 muscle fibers

Scandinavian Journal of Medicine &Science in Sports, Volume 33, Issue 2, Page 136-145, February 2023., 2023
The myotendinous junction (MTJ) is structurally specialized to transmit force. The highly folded muscle membrane at the MTJ increases the contact area between muscle and tendon and potentially the load tolerance of the MTJ. Muscles with a high content of type II fibers are more often subject to strain injury compared with muscles with type I fibers. It

A flat posterior cruciate ligament reconstruction restores native knee kinematics, comparable to a double‐bundle reconstruction—A biomechanical robotic investigation

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To biomechanically evaluate a flat posterior cruciate ligament (PCL) reconstruction utilizing rectangular femoral bone tunnels. Methods Eight fresh‐frozen human knee specimens were tested in a six‐degrees‐of‐freedom robotic test setup. In each testing step, a force‐controlled test protocol was performed, including 89 N posterior tibial

Return to competition after ACL reconstruction: Factors influencing rates and timing in Swedish football players

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the rate and timing for return to football league games after anterior cruciate ligament reconstruction (ACLR) in Swedish players, examining associations with sex, age, level, graft and additional ACL surgery. Method Data from the Swedish National Knee Registry (SNKLR) and the Swedish Football Association's IT System ...

Young age and return to play increase the likelihood of subsequent ACL reconstruction in football players: Data from the Swedish National Knee Ligament Registry

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare football players who have undergone one anterior cruciate ligament (ACL) reconstruction (ACLR) with those who have undergone a subsequent ACLR (revision or contralateral) regarding (1) demographics, (2) football‐related factors and (3) injury‐specific data.

Horizontal posterior hamstring harvest

Orthopaedics & Traumatology: Surgery & Research, 2014
Harvesting of the gracilis and semi-tendinosus (ST) hamstring tendons is usually performed by anteromedial approach. Harvesting by a horizontal posterior approach is possible. Based on a series of 90 patients, this technical note describes the perioperative difficulties and the characteristics of the harvested tendon(s) as well as any complications ...

Clinical SANTI classification of arthrogenic muscle inhibition has an excellent inter‐rater and intra‐rater reliability in preoperative and post‐operative anterior cruciate ligament rupture

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Arthrogenic muscle inhibition (AMI) is a reflexive shutdown of the quadriceps muscles following a knee injury or surgery that presents with or without hamstring contracture. This complication can be classified according to the SANTI classification, but the reproducibility of this clinical classification has not yet been demonstrated ...

Return to preinjury pivoting sports after anterior cruciate ligament reconstruction is different between males and females, as are the patient‐reported reasons

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose To investigate return to sport (RTS) after anterior cruciate ligament reconstruction (ACLR), differences based on sex and concomitant meniscal repair, and identify reasons why patients do not RTS. Methods Overall, 232 patients undergoing ACLR, with or without concomitant meniscal repair, that were actively participating in pivoting ...

Acute Proximal Hamstring Rupture

Journal of the American Academy of Orthopaedic Surgeons, 2007
Hamstring strain is common in athletes, and both diagnosis and surgical treatment of this injury are becoming more common. Nonsurgical treatment of complete ruptures has resulted in complications such as muscle weakness and sciatic neuralgia. Surgical treatment recently has been advocated to repair the complete rupture of the hamstring tendons from the
