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,

Hamstring Muscles: Architecture and Innervation [PDF]

Cells Tissues Organs, 2005
Knowledge of the anatomical organization of the hamstring muscles is necessary to understand their functions, and to assist in the development of accurate clinical and biomechanical models. The hamstring muscles were examined by dissection in six embalmed human lower limbs with the purpose of clarifying their gross morphology.

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

Choosing an allograft or autograft in orthopedic surgeries for athletes [PDF]

, 2016
Athletes and their doctors have the choice of using an allograft or autograft in reconstruction surgeries. The purpose of this study is to see if there is a difference in the healing mechanism and surgical outcome in using an allograft or autograft ...

Hamstring shortening in healthy adults

Journal of Back and Musculoskeletal Rehabilitation, 2002
Hamstring shortening (HS) causes changes in the posture and walking ability in spastic children, however, there are no studies defining the abnormalities in patellar alignment in individuals with HS.Twenty-five patients with a primary complaint of anterior knee pain, having HS detected at physical examination, and 11 healthy individuals without any HS ...

Sonographic landmarks in hamstring muscles [PDF]

Skeletal Radiology, 2019
The ultrasound examination of hamstrings inspires respect due to the connective complexity of their structures, particularly for sonographers who are not used to this kind of study. Therefore, it is important to know the specific ultrasound reference points that facilitate the location of the hamstring structures, dividing them into four areas of ...

Pain‐related fear induces aberrant drop jump landing biomechanics in healthy and anterior cruciate ligament reconstructed females

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Rupture of the anterior cruciate ligament (ACL) is a prevalent and debilitating injury typically arising from aberrant biomechanics during landing or deceleration tasks. Pain‐related fear, a component of kinesiophobia, has been associated with poor functional outcomes and altered movement patterns in individuals with ACL reconstruction

HAMSTRING ARCHITECTURAL AND FUNCTIONAL ADAPTATIONS FOLLOWING LONG VS. SHORT MUSCLE LENGTH ECCENTRIC TRAINING

Frontiers in Physiology, 2016
Most common preventive eccentric-based exercises, such as Nordic hamstring do not include any hip flexion. So, the elongation stress reached is lower than during the late swing phase of sprinting.
