Primary or Secondary Subtalar Arthrodesis and Revision of Calcaneal Nonunion with Minimally Invasive Rigid Internal Nail Fixation for Treatment of Displaced Intra-Articular Calcaneal Fractures.

Clin Podiatr Med Surg 2019 Apr 24;36(2):295-306. Epub 2019 Jan 24.

Department of Trauma, Hand and Reconstructive Surgery, Rostock University Medical Center, Schillingallee 35, Rostock D-18057, Germany. Electronic address:

Primary or secondary subtalar joint arthrodesis after displaced intra-articular calcaneal fractures makes use of talocalcaneal large-diameter screw fixation after an eventual correction of geometric hindfoot deformity. Despite this procedure usually having a successful functional outcome, potential complications occur, including nonunion and malalignment, with an unknown rate of loss of correction or implant migration during the healing period. Angular stable fixation of the subtalar joint arthrodesis with an interlocking nail applied in a minimally invasive technique affords maintenance of the hindfoot position until osseous healing occurs.

Evaluation of an accelerometer to assess knee mechanics during a drop landing.

J Biomech 2019 Feb 12. Epub 2019 Feb 12.

Department of Kinesiology, University of Wisconsin-Milwaukee, Milwaukee, WI, USA.

Non-contact anterior cruciate ligament (ACL) injuries account for 70% of all ACL injuries, and can lead to missed time from activity for athletes and a predisposition for knee osteoarthritis. Prior research has shown that athletes who land in a stiff manner, with larger internal knee adduction and extension moments, are at greater risk for an ACL injury. A three-dimensional accelerometer placed at the tibial tuberosity may prove to be a low-cost means of assessing these risk factors. Read More

High annual surgeon volume reduces the risk of adverse events following primary total hip arthroplasty: a registry-based study of 12,100 cases in Western Sweden.

Acta Orthop 2019 Feb 14:1-15. Epub 2019 Feb 14.

a Department of Orthopaedics, Institute of Clinical Sciences, The Sahlgrenska Academy , University of Gothenburg , Gothenburg , Sweden.

Background and purpose - Most earlier publications investigating whether annual surgeon volume is associated with lower levels of adverse events (AE), reoperations, and mortality are based on patient cohorts from North America. There is also a lack of adjustment for important confounders in these studies. Therefore, we investigated whether higher annual surgeon volume is associated with a lower risk of adverse events and mortality within 90 days following primary total hip arthroplasty (THA).

Potential Novel Prediction of TMJ-OA: MiR-140-5p Regulates Inflammation Through Smad/TGF-β Signaling.

Front Pharmacol 2019 23;10:15. Epub 2019 Jan 23.

Department of Dental Research, School of Stomatology, Kunming Medical University, Kunming, China.

Temporomandibular joint osteoarthritis (TMJ-OA), mainly exhibit extracellular matrix loss and condylar cartilage degradation, is the most common chronic and degenerative maxillofacial osteoarthritis; however, no efficient therapy for TMJ-OA exists due to the poor understanding of its pathological progression. MicroRNA (miR)-140-5p is a novel non-coding microRNAs (miRNAs) that expressed in osteoarthritis specifically. To investigate the molecular mechanisms of miR-140-5p in TMJ-OA, primary mandibular condylar chondrocytes (MCCs) from C57BL/6N mice were treated with interleukins (IL)-1β or transfected with miR-140-5p mimics or inhibitors, respectively.

Total Knee Arthroplasty for Fixed Valgus Deformity Correction Using a Modified Lateral Parapatellar Approach.

J Knee Surg 2019 Feb 6. Epub 2019 Feb 6.

Department of Orthopaedic Surgery, Peking University People's Hospital, Beijing, China.

Total knee arthroplasty (TKA) for patients with valgus deformity (> 10 degrees) is technically challenging and has produced variable clinical results in terms of deformity correction, instability, and overall outcomes. The lateral parapatellar approach (LPA) is an alternative to the traditional medial parapatellar approach with potential advantages of direct access for release of tight lateral ligamentous structures with preservation of the medial structures, optimized patellar tracking, preserved medial blood supply to the patella, and less use of constrained implants. We present a case series of a single institution's experience with use of a modified LPA using a Z-capsuloplasty for 35 primary TKA cases in 30 patients with osteoarthritis and Ranawat's type-II fixed valgus deformity with attenuation of medial soft tissues.
