Currently, no consensus exists for the optimal graft fixation angle for anatomic single-bundle (SB) posterior cruciate ligament reconstructions (PCLRs). Additionally, direct graft forces have not been measured. Alternative graft fixation angles and the resultant graft forces should be investigated to optimize the stability of SB PCLRs without overconstraining the knee. The results of this study […]
Classically, hip capsule tears are treated with surgical repair; however, there may be a role for less invasive therapies in select patients with certain occult hip capsular injuries. This particular study involved a 27-year old male professional soccer player who developed heterotopic ossification of the hip casule, and gluteus minimus tendon after an arthroscopic […]
The deltoid ligament has both superficial and deep layers, consiting of up to six ligamentous bands. The prevalence of the individual bands are variable with no consensus as to which bands are constant or variable. This study analyzes the variance in the deltoid anatomy through quantified distance to relevant […]
Recent biomechanical evidence suggests that the meniscus-suture interface contributes the most displacement to the transtibial pull-out repair for meniscal root tears. Therefore, optimization of surgical technique at the meniscus-suture interface may minimize displacement and improve the strength of meniscal root repairs.
The purpose of this study was to investigate the cyclic displacement and ultimate failure […]
The histologic appearance of the repair tissue after articular cartilage resurfacing procedures in humans is not well documented.
Objective measures to quantitate the amount of lateral compartment opening for patients with lateral and posterolateral knee injuries have not been well documented. The purpose of the present study was to measure lateral compartment opening secondary to applied varus stresses following posterolateral corner structure sectioning and to develop radiographic […]
The development of an in vivo animal model of posterolateral knee instability is desired for devising effective interventions for this injury. Sequential sectioning of the popliteus tendon, lateral collateral ligament, and lateral capsule was done in cadaveric goat knees to create knee joint instability, followed by in vivo studies (Studies 1 […]
This study went into detail about the current concepts of the treatment of medial knee injuries. Comprehensive anatomy, clinically relevant biomechanics, and treatment of both acute and chronic medial-sided knee injuries were reviewed. A very detailed non-operative and post-operative rehabilitation protocol for medial knee injuries was also provided based on […]
Objective measures to quantitate the amount of lateral compartment opening for patients with lateral and posterolateral knee injuries have not been well documented. The purpose of the present study was to measure lateral compartment opening secondary to applied varus stresses following posterolateral corner structure sectioning and to develop radiographic […]
Glenohumeral motion presents challenges for its accurate description across all available ranges of motion using conventional Euler/Cardan angle sequences without singularity. A comparison of the description of glenohumeral motion was made using the ISB recommended YX´Y” sequence to the XZ’Y” sequence.
