High-resolution microCT analysis of sclerotic subchondral bone beneath bone-on-bone wear grooves in severe osteoarthritis.

Osteoarthritis (OA) is associated with sclerosis, a thickening of the subchondral bone plate, yet little is known about bone adaptations around full-thickness cartilage defects in severe knee OA, particularly beneath bone-on-bone wear grooves. This high-resolution micro-computed tomography (microCT) study aimed to quantify subchondral bone microstructure relative to cartilage defect location, distance from the joint space, and groove depth. Ten tibial plateaus with full-thickness cartilage defects were microCT-scanned to determine defect location and size.

Good vibes for the brain - Placebo versus real vibration in patients with chronic neck pain: A randomized cross-over study.

Background: Neck muscle vibration decreases pain and improves sensorimotor impairments in patients with chronic neck pain. However, the impact of placebo on these effects are still unclear.

Objective: The aim was to evaluate the effect of neck muscle vibration compared to placebo neck muscle vibration in patients with chronic neck pain.

Anterior Cruciate Ligament (ACL) Repair Using Dynamic Intraligamentary Stabilization Combined with Lateral Extra-articular Augmentation: A Case Report and Technical Note.

The treatment options for an anterior cruciate ligament (ACL) rupture range from conservative therapy to ACL repair and reconstruction. ACL repair is particularly suitable for younger patients with an acute proximal tear, and moderate athletic demand. Preserving the ACL can restore its proprioceptive and stabilizing functions, avoid donor site morbidity, and shorten rehabilitation time.

Seed morphometrics unravels the evolutionary history of grapevine in France.

The cultivation of grapevines has spanned millennia, leading to thousands of varieties through exchanges, mutations, and crosses between genotypes, as well probably as gene flow from wild populations. These varieties are typically categorized by regional origin and primary use, either for wine production or fruit consumption. France, within the Western European group, hosts many of the world's renowned wine grape varieties.

Comparable results in total knee arthroplasty using the ROSA knee system versus the conventional technique: A retrospective propensity-matched cohort study.

Purpose: Robotic-assisted total knee arthroplasty (RA-TKA) is an increasingly popular alternative that may increase the accuracy of conventional TKA techniques. This study aims to evaluate RA-TKA accuracy and compare its radiographic and clinical outcomes to conventional TKA (cTKA).

Methods: A retrospective examination of patients with bi- or tricompartmental knee osteoarthritis who underwent RA-TKA (RObotic Surgical Assistant system) or cTKA and were prospectively documented in the TKA registry.
