Revision Patellar Tendon Repair With Anchors, Allograft Augmentation, and Suspensory Fixation

Arthroscopy Techniques, 2020
Ruptures of the patellar tendon are rare but potentially devastating injuries reported to occur most commonly in active males in their third and fourth decades of life. Repair failure rates have been reported to range between 2% and 50% based on surgical

Specimen dimensions influence the measurement of material properties in tendon fascicles [PDF]

, 2010
Stress, strain and modulus are regularly used to characterize material properties of tissue samples. However, when comparing results from different studies it is evident the reported material properties, particularly failure strains, vary hugely. The aim

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,

Transosseous-Equivalent Repair for Distal Patellar Tendon Avulsion

Arthroscopy Techniques, 2016
Extensor mechanism disruptions are relatively uncommon injuries involving injury to the quadriceps tendon, patella, or patellar tendon. Patellar tendon avulsions from the tibial tubercle in adults are rare; as such, little technical information has been ...

Patellar Tendon–Trochlear Groove Angle Measurement

Orthopaedic Journal of Sports Medicine, 2015
Background: The tibial tubercle–trochlear groove (TT-TG) is used as the gold standard for patellofemoral malalignment. Purpose: To assess 3 patellar tendon–trochlear groove (PT-TG) angle measurement techniques and the PT-TG distance measurement ...

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

Comparison of double bundle semitendinosus technique and pedicled quadriceps technique in patellar instability

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare clinical and functional outcomes of medial patellofemoral ligament (MPFL) reconstruction using a minimally invasive pedicled quadriceps tendon (QT) or patella double tunnel technique with semitendinosus tendon (ST) graft in patients with recurrent patella dislocation.

Patellar Tendon Lengthening: Rescue Procedure for Patella Baja

Arthroscopy Techniques, 2020
Patella baja is a challenging pathologic condition that causes pain and functional restrictions and can even lead to premature osteoarthritis—even more so in cases of patella infera or cases associated with degeneration of the patellar tendon in which ...
