Background: The objective of this study was to determine the cartilage volume and surface area of male and female Beagle dog knees using 3D (3 dimensional) reconstructed MRI images.
Methods: Six Beagle Dogs (Canis familiaris) (3 males and 3 females) of 10-18 months old and weighing between 7.2 and 17.1 kg underwent a MRI evaluation of both knees. The data acquired allowed a 3D reconstruction of the knee and measurement of the cartilage volume and surface area.
Results: Mean knee cartilage volume (averaged over the right and left knees) of animals between 7.2 and 17.1 kg ranged from 319.7 to 647.3 mm; while the mean knee cartilage surface area ranged from 427.14 to 757.2 mm. There was evidence of both knee volume and surface area increasing linearly with animal bodyweight.
Conclusions: The cartilage volume and surface area of the Beagle dog appears to correlate significantly with body weight. This study provides a reference base for future studies investigating cartilage related pathology such as osteoarthritis.

Background: Three-dimensional MR fingerprinting (3D-MRF) has been increasingly used to assess cartilage degeneration, particularly in the knee joint, by looking into multiple relaxation parameters. A comparable 3D-MRF approach can be adapted to assess cartilage degeneration for the hip joint, with changes to accommodate specific challenges of hip joint imaging.
Purpose: To demonstrate the feasibility and repeatability of 3D-MRF in the bilateral hip jointly we map proton density (PD), T, T, T, and ∆B in clinically feasible scan times.

Magnetic microrobot swarms have broad application prospects in human-targeted therapy. However, the automated assembly and actuation of functional large-volume swarms is a challenging topic. Chlorella with self-fluorescence and biodegradability is used in this paper as a template to prepare magnetic Chlorella-based microrobots through magnetron sputtering.

Objective: To explore clinical efficacy of platelet rich plasma (PRP) injection combined with extracorporeal shock wave therapy (ESWT) in treating osteochondral lesion of talus (OLT) with typeⅡa.
Methods: From January 2022 to June 2022, 45 patients with typeⅡa OLT were treated with PRP arthroscopic injection combined with ESWT, including 29 males and 16 females; aged from 18 to 63 years old with an average of(37.7±10.

Objective: This study aimed to assess the effects of an antioxidant-conjugated Hyaluronic Acid (HA), specifically HA-4-aminoresorcinol (HA4AR), on articular cartilage and subchondral bone in osteoarthritis (OA). We conducted a comparative analysis between HA4AR and a commercially available high molecular weight HA formulation in a rabbit model of OA.
Materials And Methods: Eighteen rabbits underwent unilateral anterior cruciate ligament transection (ACLT) and were divided into three groups of six: Saline-group, HA-group, and HA4AR-group, based on the type of intra-articular injection received.
