Knee pain in young, active patients with meniscus-deficient knees and articular cartilage damage can present a challenge to treatment. Meniscal allograft transplantation (MAT) has shown good clinical results as treatment for meniscus deficiency; however, worse outcomes have been observed in patients with significant chondral damage. The development of chondral restorative techniques such as osteochondral allograft transplantation (OCA) has expanded the population of patients who may benefit from MAT. We present a case of proximal tibial osteochondral and lateral meniscal allograft transplant...

The loss and degradation of articular cartilage tissue matrix play central roles in the process of osteoarthritis (OA). New models for evaluating cartilage repair/regeneration are thus of great value for transferring various culture systems into clinically relevant situations. The repair process can be better monitored in ex vivo systems than in in vitro cell cultures. I have therefore established an ex vivo defect model prepared from bovine femoral condyles for evaluating cartilage repair by the implantation of cells cultured in various ways, e...

OBJECTIVES: Based on a novel approach suggesting a role of adipose tissue in osteoarthritis (OA), we aimed to determine whether the infrapatellar fat pad (IFP) may affect joint cell functions through adipokines. METHODS: The conditioned media of IFP and subcutaneous adipose tissue from OA patients were used to determine the production of leptin and adiponectin, and to stimulate chondrocytes and fibroblast-like synoviocytes (FLS). Blocking experiments were carried out to evaluate the contribution of adipokines to IFP effects...

This study aims to investigate the effects of p38-MAPK signaling pathway on the apoptosis and expression of proinflammatory cytokines in human osteoarthritis (OA) chondrocytes. Human articular cartilage specimens were obtained from 57 OA patients and 31 patients with lower extremity traumatic amputations. The expressions of p38-MAPK pathway-related proteins in cartilage tissue were detected by immunochemistry. Cultured chondrocytes isolated from human OA cartilage were assigned into the blank group, the IL-1β group, the PD (PD980959, ERK pathway inhibitors)+IL-1β group, the SB (SB203580, p38 pathway inhibitors)+IL-1β group, and the SP (SP600125, JNK signaling pathway inhibitors)+IL-1β group...

BACKGROUND: Osteochondral defects continue to be a clinical treatment challenge, and when left untreated, may cause pain and functional impairment. Pyrolytic carbon is a unique isotropic biomaterial used in heart valve and small joint replacements due to its excellent wear properties and biocompatibility with bone and articular cartilage. Therefore, a proposed solution is to utilize a focal pyrolytic carbon hemiarthroplasty implant as an alternative resurfacing treatment strategy for isolated cartilage lesions...

BACKGROUND: Several modalities of treatment are being used for the management of proximal humerus fractures. Primary hemiarthroplasty in proximal humerus fracture is indicated in three or four part fracture or fracture dislocations. It is also indicated if fracture involves a large area of articular cartilage loss and viability of head is doubtful. We studied the functional outcome of hemiarthroplasty in comminuted proximal humerus fracture. MATERIALS AND METHODS: 29 patients of three or four part proximal humerus fractures, (according to Neer's classification) who underwent primary shoulder hemiarthroplasty were included in this retrospective study...

The highly sulfated glycosaminoglycan (GAG) heparin is widely used in the clinic as an anticoagulant, and researchers are now using it to enhance stem cell expansion/ differentiation protocols, as well as to improve the delivery of growth factors for tissue engineering strategies. Growth differentiation factor 5 (GDF5) belongs to the bone morphogenetic protein family of proteins and is vital for skeletal formation, however, its interaction with heparin and heparan sulfate (HS) has not been studied. We identify GDF5 as a novel heparin/ HS-binding protein, and show that HS proteoglycans are vital in localizing GDF5 to the cell surface...

The decision-making regarding and treatment of cartilage abnormalities requires a systematic approach. This article reviews the concepts and principles that guide the management of this complex problem. The precise incidence, demographics, and progression of cartilage lesions have not been clearly delineated. Pursuing a patient-centered approach that considers the available nonsurgical and surgical options remains the cornerstone of patient care. The importance of determining concomitant knee pathologies, the proper interpretation and implications of imaging findings, and an accurate determination of the intra-articular and subchondral findings represent the primary elements of the decision analysis...

The goal of this study was to characterize antibody penetration through cartilage tissue under mechanical loading. Mechanical stimulation aids in the penetration of some proteins, but this effect has not characterized molecules such as antibodies (>100 kDa), which may hold some clinical value for treating osteoarthritis (OA). For each experiment, fresh articular cartilage plugs were obtained and exposed to fluorescently labeled antibodies while under cyclic mechanical load in unconfined compression for several hours...

The wrist's function is at stake in young active adults with partial intra-articular fractures of the distal radius. The high energy nature of these injuries, displaced fractures with risk of malunion in case of insufficient treatment, and associated ligament or cartilage damage all hinder the prognosis of these fractures. Many classification systems exist to help us analyze and in some cases, select a treatment. Optimal management requires a high-quality preoperative assessment and a precise surgical technique coupled with the use of arthroscopy to deal with joint and ligament injuries in the same operation...

Management of malunion of the distal radius remains difficult. Planning of the correction of the articular displacement requires a comprehensive analysis by CT arthrography to analyze bone, cartilage and ligaments. Arthroscopy is a valuable tool in the context of joint trauma. In the absence of osteoarthritis, the correction can be carried out as early as possible in the weeks or months following the initial fracture. The use of locking plates allows early mobilization after surgery. This correction aims to prevent the development of secondary osteoarthritis...
