Cartilage repairing graft had been widely studied and the osteochondral replacement hydrogels were proved to be an excellent method in research and clinical. However, it was difficult to solve three main issues in osteochondral replacement preparation at one time: surface lubrication, overall mechanical support and good simulations of cell regeneration. A novel integrated bilayered hydrogel osteochondral replacement was constructed by blending polyvinyl alcohol (PVA) and β-tricalcium phosphate (β-TCP) in this study...

The effective management of temporomandibular dysfunction (TMD) requires a thorough understanding of the pathoanatomic factors that drive the underlying condition. After reviewing the etiology associated with TMD in Part 1 of this narrative review, the temporomandibular joint capsule, articular disc and muscles of mastication emerged as key players. (http://dx.doi.org/10.​1016/​j.​jbmt.​2017.​05.​017) Part 2 focuses on conservative treatment strategies best able to reduce the pain and disability associated with TMD...

This work describes a technique of platelet-rich plasma (PRP) infiltration for the treatment of severe hip osteoarthritis (OA). Although the results achieved with intra-articular infiltrations of PRP are promising, they may be insufficient in the long-term for severe hip OA. The technique consists of a combined intra-articular and intraosseous infiltration of PRP to reach all joint tissues, especially the subchondral bone, and hence facilitate a greater distribution of PRP. Diagnosis is based on clinical and radiographic findings, and patients with grade III OA according to the Tönnis scale, as well as patients who have not responded to conventional treatment, are considered candidates for this technique...

#8
EDITORIAL
Michael J Rossi
Ultrasound (US) examination of the anterolateral ligament (ALL) in the anterior cruciate ligament-deficient knee betters magnetic resonance imaging analysis with slightly higher identification rate of the entire ALL presumably due to the ability to test in a functional pivot shift configuration. The ALL was injured in 63% of the anterior cruciate ligament-deficient knees and the injury occurred at the tibial insertion in all cases. Although the authors propose US to be the new "gold standard" for diagnosing ALL injuries, there still remains a question of whether there is any necessity for an US diagnosis of ALL injury when the pivot shift test may provide the necessary information, and the consensus for ALL reconstruction or lateral extra-articular tenodesis has yet to be reached...

Dislocation and injury of the biceps is associated with acute and chronic trauma, degenerative changes, repetitive microtrauma, or injuries associated with recurrent and neglected cases of shoulder dislocation. The cases of displaced biceps injuries are relatively rare (only 1/6(th) of all rotator cuff injuries). The dislocation of biceps is manifested with pain and restriction of movements. The X-ray shoulder is not of much help in this condition barring for ruling out the fractures of humerus and scapula...

CONTEXT:   Understanding the factors associated with thicker cartilage in a healthy population is important when developing strategies aimed at minimizing the cartilage thinning associated with knee osteoarthritis progression. Thicker articular cartilage is commonly thought to be healthier cartilage, but whether the sagittal-plane biomechanics important to gait are related to cartilage thickness is unknown. OBJECTIVE:   To determine the relationship of a weight-bearing region of the medial femoral condyle's cartilage thickness to sagittal gait biomechanics in healthy individuals...

Research is ongoing to develop drug therapies to manage osteoarthritis (OA) and articular cartilage (AC) injuries. However, means to deliver drug to localized AC lesions are highly limited and not clinically available. This study investigates the capability of laser ultrasound (laser-induced plasma sound source) to deliver agents (methylene blue, MB, in PBS) into bovine AC. Treatment samples (n = 10) were immersed in MB solution simultaneously with LU exposure, while adjacent control 1 tissue (n = 10) was pre-treated with LU followed by immersion in MB and adjacent control 2 tissue (n = 10) was only immersed in MB...

Ultrasound (US) is a therapeutic modality that has been used in the treatment of musculoskeletal conditions for decades. In recent years, there have been technological advancements using low-intensity pulsed ultrasound (LIPUS) as a clinical modality. The purpose of this review was to critically examine the medical literature to determine the effects of LIPUS on the chondrogenic properties of knee osteoarthritis. A literature search of 3 major databases (PubMed, Scopus, and EMBASE) was performed. Two independent physician reviewers screened titles and abstracts, yielding a total of 18 relevant articles after the inclusion and exclusion criteria were applied...

The potential of quantitative ultrasound (QUS) to assess the regular cellular spacing in the superficial cartilage zones was investigated experimentally and numerically. Nine osteochondral samples, extracted from two human cadaver knee joints, were measured using a 50-MHz ultrasound scanning device and evaluated using Mankin score. Simulated backscattered power spectra from models with an idealized cell alignment exhibited a pronounced frequency peak. From the peak, cell spacing in the range between 15 and 40 μm between cell layers was detected with an average error of 0...
