Effects of abaloparatide and teriparatide on bone resorption and bone formation in female mice.

Bone Rep 2020 Dec 26;13:100291. Epub 2020 Jun 26.

Radius Health Inc., Waltham, MA, USA.

Intermittent administration of PTH type 1 receptor (PTH1R) agonists increases bone remodeling, with greater stimulation of bone formation relative to bone resorption causing net gains in bone mass. This pharmacodynamic feature underlies the bone-building effects of teriparatide and abaloparatide, the only PTH1R agonists approved to reduce osteoporotic fracture risk in postmenopausal women. This study in 8-week-old female mice compared bone resorption and formation responses to these agents delivered at the same 10 μg/kg dose, and a 40 μg/kg abaloparatide dose was also included to reflect its 4-fold higher approved clinical dose.

In-Vivo Three-Dimensional Knee Kinematics in Goats with Unilateral Anterior Cruciate Ligament Transection.

J Orthop Res 2020 Jul 7. Epub 2020 Jul 7.

Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Florida, Gainesville, FL.

Although the goat is an established animal model in anterior cruciate ligament (ACL) research, in-vivo kinematics associated with ACL deficiency have not been previously described in this species. Three-dimensional knee kinematics were determined before and after unilateral ACL transection in eight goats. Fluoroscopic imaging of the knees during treadmill walking, and force-platform gait analysis during over-ground walking, were performed prior to ACL transection, and 2 weeks, 3 months, and 6 months after ACL transection.

Comparison of Tip- Versus Hub-Oscillating Saw Blade Control in a Total Knee Arthroplasty Model.

J Arthroplasty 2020 Jun 15. Epub 2020 Jun 15.

Department of Orthopaedics and Rehabilitation, University of Vermont, Burlington, VT.

Background: Oscillating saws are commonly used for bone preparation in total knee arthroplasty but can cause injury to the posterior neurovascular bundle during tibial resection. Tip-oscillating saw blades are a recent innovation that could improve saw control due to decreased excursion; however, the tactile feedback to the surgeon is different.

Methods: To compare traditional hub and new tip-oscillating saw blades, 16 participants of varying levels of experience were video-recorded during composite tibial bone model resections to measure posterior saw blade plunge. Read More

Periprosthetic Loss of Bone Mineral Density After Cementless Porous Tantalum and Cemented Total Knee Arthroplasties: A Mean of 11-Year Concise Follow-Up of a Previous Report.

J Arthroplasty 2020 Jun 12. Epub 2020 Jun 12.

Department of Orthopaedic Surgery, Osaka City University Graduate School of Medicine, Osaka, Japan.

Background: Our previous study showed that the decrease in relative change of bone mineral density (BMD) in the lateral part of the tibia was significantly less in the group treated with the cementless porous tantalum component than in the group treated with the cemented cobalt-chromium tibial component up to 5 years after the operation. However, the long-term benefits of porous tantalum tibial component on BMD have not been proven. The aim of this study was to update a matched cohort study at a minimum of 6 years' follow-up period.
