Enhanced osteochondral repair with hyaline cartilage formation using an extracellular matrix-inspired natural scaffold.

Osteochondral defects pose a great challenge and a satisfactory strategy for their repair has yet to be identified. In particular, poor repair could result in the generation of fibrous cartilage and subchondral bone, causing the degeneration of osteochondral tissue and eventually leading to repair failure. Herein, taking inspiration from the chemical elements inherent in the natural extracellular matrix (ECM), we proposed a novel ECM-mimicking scaffold composed of natural polysaccharides and polypeptides for osteochondral repair.

The efficacy of medial meniscal posterior Root tear Repair with or without high tibial osteotomy: a systematic review.

Background: Medial meniscal posterior root tear (MMPRTs) is a common lesion of the knee joint, and repair surgery is a well-established treatment option. However, patients with obvious varus alignment are at an increased risk for MMPRT and can suffer from a greater degree of medial meniscus extrusion, which leads to the development of osteoarthritis following repair. The efficacy of high tibial osteotomy (HTO) as a means of correcting this malformation, and its potential benefits for MMPRT repair, remains unclear.

Meniscus heterogeneity and 3D-printed strategies for engineering anisotropic meniscus.

The meniscus is a fibrocartilaginous tissue of the knee joint that plays an important role in load transmission, shock absorption, joint stability maintenance, and contact stress reduction. Mild meniscal injuries can be treated with simple sutures, whereas severe injuries inevitably require meniscectomy. Meniscectomy destroys the mechanical microenvironment of the knee joint, leading to cartilage degeneration and osteoarthritis.

Shoe-Integrated Sensor System for Diagnosis of the Concomitant Syndesmotic Injury in Chronic Lateral Ankle Instability: A Prospective Double-Blind Diagnostic Test.

Chronic lateral ankle instability (CLAI) is commonly secondary to prior lateral ankle ligament injury, and the concomitant latent syndesmosis injury would prolong recovery time and increase the risk of substantial traumatic arthritis. However, differentiating syndesmotic injury from isolated lateral ankle ligament injury in CLAI cases is difficult by conventional physical and radiological examinations. To improve the accuracy of syndesmotic injury diagnosis, a shoe-integrated sensor system (SISS) is proposed.
