Osteoarthritis (OA) is common age-associated disease, and associated with joint pain, mobility limitations and compromised overall quality of life. OA treatment is currently limited to pain management and joint arthroplasty at end stage disease. Oxidative damage to cartilage extracellular matrix and cells is an important mechanism in joint aging and OA pathogenesis. Evidence from in vitro and in vivo models of OA suggests that pharmaceuticals and natural compounds with antioxidant properties reduce expression of mediators of OA pathogenesis and OA severity in animal models...

OBJECTIVE: Anterior cruciate ligament (ACL) tears increase early onset osteoarthritis (OA) risk leading to cartilage and bone degradation. While the contribution of bone in OA development is unclear, evidence suggests that bone changes accompany cartilage degradation. This study aims to assess if regions with differences in subchondral bone plate thickness have differences in cartilage thickness when comparing ACL reconstructed (ACLR) knees of women ≥5 years post-injury to contralateral and controls with uninjured knees...

A dynamic musculoskeletal model of the elbow joint in which muscle, ligament, and articular surface contact forces are predicted concurrently would be an ideal tool for patient-specific preoperative planning, computer-aided surgery, and rehabilitation. Existing musculoskeletal elbow joint models have limited clinical applicability because of idealizing the elbow as a mechanical hinge joint or ignoring important soft tissue (e.g., cartilage) contributions. The purpose of this study was to develop a subject-specific anatomically correct musculoskeletal elbow joint model and evaluate it based on experimental kinematics and muscle electromyography measurements...

Marcello Lughi
Ankle sprain can cause injuries to the anatomic structures surrounding the tibiotarsal joint. A possible extra-articular pathology is to be hypothesized and diagnosed as early as possible. The subtalar joint, for anatomical and functional reasons, is one of the most damaged joints following an ankle sprain. In spite of this, its involvement is often underestimated. The clinical case presented in the present article is referred to a giant cells osseous tumor in the tarsal canal that was diagnosed 2 months after an inversion ankle sprain...

Large osteochondral allograft (OCA) transplant has become a valid alternative to restore articular surface in challenging articular lesions in young and active patients, either in primary or in revision procedures. Several studies support the effectiveness and safety of OCA, but costs and graft availability limit their use. The indications are the treatment of symptomatic full-thickness cartilage lesions greater than 3 cm 2 , deep lesions with subchondral damage, or revision procedures when a previous treatment has failed...

We implemented direct collocation on a full-body neuromusculoskeletal model to calculate muscle forces, ground reaction forces and knee contact loading simultaneously for one cycle of human gait. A data-tracking collocation problem was solved for walking at the normal speed to establish the practicality of incorporating a 3D model of articular contact and a model of foot-ground interaction explicitly in a dynamic optimization simulation. The data-tracking solution then was used as an initial guess to solve predictive collocation problems, where novel patterns of movement were generated for walking at slow and fast speeds, independent of experimental data...

We dissected 30 cadaveric thumb interphalangeal joints to delineate the sensory nerve anatomy of its capsule. Four articular branches supplying the interphalangeal joint capsule of the thumb were found in all specimens. Ulnar and radial proper digital nerves provide one palmar capsular nerve branch on their respective sides. Of the two dorsal branches of the radial nerve at the dorsum of the thumb, we observed that each nerve provided one branch to the interphalangeal dorsal capsule. Our findings demonstrate a consistent pattern of innervation and may provide the anatomical basis to the treating surgeon for an effective and safe denervation of the interphalangeal joint of the thumb...

Orthopaedic surgeons commonly have the misconception that patients with tibial plateau fractures will likely go on to posttraumatic knee arthritis requiring total knee arthroplasty (TKA). In younger patients, osteochondral allograft (OCA) transplantation is an alternative method to address posttraumatic knee arthritis. The purpose of this study was (1) to identify our institutional failure rate following tibial plateau open reduction and internal fixation (ORIF) (failure was defined as conversion to TKA or OCA); (2) to determine if there are patient- or injury-related risk factors predictive of failure; and (3) to characterize differences between patients treated with TKA versus those treated with OCA transplantation...

RATIONALE: Transforaminal lumbar interbody fusion (TLIF) is an effective treatment for patients with degenerative lumbar disc disorder. Contralateral radiculopathy, as a complication of TLIF, has been recognized in this institution, but is rarely reported in the literature. PATIENT CONCERNS: In this article, we report 2 cases of contralateral radiculopathy after TLIF in our institution and its associated complications. DIAGNOSES: In the 2 cases, the postoperative computed tomography (CT) and magnetic resonance image (MRI) showed obvious upward movement of the superior articular process, leading to contralateral foraminal stenosis...
