Cartilage and Bone Serum Biomarkers as Novel Tools for Monitoring Knee Osteochondritis Dissecans Treated with Osteochondral Scaffold.

Biomed Res Int 2018 23;2018:9275102. Epub 2018 Dec 23.

IRCCS Istituto Ortopedico Rizzoli, SC Laboratorio di Immunoreumatologia e Rigenerazione Tissutale, Via di Barbiano 1/10, 40136 Bologna, Italy.

Knee osteochondritis dissecans (OCD) is a focal disease of the joint characterized by modifications of bone and cartilage tissues. Biomimetic osteochondral scaffolds are used to restore these tissues. The aim of this prognostic prospective cohort study was to evaluate serum biomarkers of cartilage (fragments or propeptide of type II collagen: CTXII, C2C, and CPII) and bone (tartrate-resistant acid phosphatase (TRAP) 5b and osteocalcin (OC)) turnover during follow-up of patients treated with an osteochondral scaffold, to identify which were related to healing outcome and clinical score.

Editorial Commentary: "There's No Crying in Baseball," But There Is Osteochondritis Dissecans of the Elbow.

Authors:
Taylor D Brown

Arthroscopy 2019 Jan;35(1):67-69

Osteochondritis dissecans of the capitellum is a rare and ultrasonically identifiable disease of the dominant elbow of preadolescent baseball players as young as 9 years of age. We must choose to protect these young players, either by initiating a screening program to identify the disease at an early stage when treatment results in an acceptable lifelong outcome or by vociferously limiting the daily, weekly, and yearly participation in this vulnerable group.

Identification of Areas of Epiphyseal Cartilage Necrosis at Predilection Sites of Juvenile Osteochondritis Dissecans in Pediatric Cadavers.

J Bone Joint Surg Am 2018 Dec;100(24):2132-2139

Department of Veterinary Clinical Sciences, University of Minnesota, St. Paul, Minnesota.

Background: The pathogenesis of human juvenile osteochondritis dissecans (JOCD) remains poorly understood, with multiple factors implicated, including ischemia, repetitive trauma, and genetic predisposition. Similarities in the predilection site and the diagnostic and clinical features of JOCD to the well-characterized veterinary counterpart, osteochondrosis dissecans, suggest that, similar to the animal disease, the pathogenesis JOCD may also be initiated in the first few years of life, when disruption of blood supply to the epiphyseal growth cartilage leads to failure of endochondral ossification. To gather data in support of the hypothesis that JOCD and osteochondrosis dissecans have a shared pathogenesis, biopsy specimens obtained from predilection sites of JOCD in juvenile human cadavers were histologically examined to determine whether they contained lesions similar to those found in animals diagnosed with subclinical osteochondrosis dissecans.

Treatment of unstable knee osteochondritis dissecans in the young adult: results and limitations of surgical strategies-The advantages of allografts to address an osteochondral challenge.

Knee Surg Sports Traumatol Arthrosc 2018 Dec 6. Epub 2018 Dec 6.

Department of Orthopaedics and Rehabilitation, Oregon Health & Science University, Portland, Oregon, USA.

Joint surface incongruence resulting from osteochondritis dissecans (OCD) alters the articular physiologic congruence, increasing the contact stress on adjacent joint surfaces and accelerating wear and the cascade of joint degeneration. Accordingly, the restoration of articular surface integrity is of major importance, especially in young adults where, in lesions left untreated or following simple fragment excision, early osteoarthritis can be anticipated. Therefore, the treatment algorithm in unstable knee OCD of the young adult foresees surgical options to restore the articular surface. Read More

Overuse injuries in sport: a comprehensive overview.

J Orthop Surg Res 2018 Dec 5;13(1):309. Epub 2018 Dec 5.

Department of Musculoskeletal Disorders, School of Medicine and Dentistry, University of Salerno, Salerno, Italy.

Background: The absence of a single, identifiable traumatic cause has been traditionally used as a definition for a causative factor of overuse injury. Excessive loading, insufficient recovery, and underpreparedness can increase injury risk by exposing athletes to relatively large changes in load. The musculoskeletal system, if subjected to excessive stress, can suffer from various types of overuse injuries which may affect the bone, muscles, tendons, and ligaments. Read More

Osteochondral Lesions of the Knee: Differentiating the Most Common Entities at MRI.

Radiographics 2018 Sep-Oct;38(5):1478-1495. Epub 2018 Aug 17.

From the Department of Radiology, Einstein Healthcare Network, 5501 Old York Rd, Philadelphia, PA 19141 (T.G, M.C., B.W.C.) and Department of Radiology, University of Alabama at Birmingham, Birmingham, Ala (Y.M.).

Several pathologic conditions may manifest as an osteochondral lesion of the knee that consists of a localized abnormality involving subchondral marrow, subchondral bone, and articular cartilage. Although understanding of these conditions has evolved substantially with the use of high-spatial-resolution MRI and histologic correlation, it is impeded by inconsistent terminology and ambiguous abbreviations. Common entities include acute traumatic osteochondral injuries, subchondral insufficiency fracture, so-called spontaneous osteonecrosis of the knee, avascular necrosis, osteochondritis dissecans, and localized osteochondral abnormalities in osteoarthritis.

Expression of pro-apoptotic markers is increased along the osteochondral junction in naturally occurring osteochondrosis.

Bone Rep 2018 Dec 21;9:19-26. Epub 2018 Jun 21.

Department of Clinical Sciences, College of Veterinary Medicine, Oregon State University, Corvallis, OR 97331, USA.

Osteochondrosis (OC) is a naturally occurring disease of the articular-epiphyseal cartilage and subchondral bone layers, leading to pain and decreased mobility. The objective of this study was to characterize gene and protein expression of apoptotic markers in chondrocytes surrounding cartilage canals and along the osteochondral junction of osteochondrosis (OC)-affected and normal cartilage, using naturally occurring disease in horses. Paraffin-embedded osteochondral samples (6 OC, 8 normal controls) and cDNA from chondrocytes captured with laser capture microdissection (4 OC, 6 normal controls) were obtained from the lateral trochlear ridge of femoropatellar joints in 14 immature horses (1-6 months of age).
