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

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.

Editorial Commentary: To Treat or Not to Treat? Are We Any Closer to Knowing What to Do With Cartilage Lesions of the Tibia?

Authors:
William Bugbee

Arthroscopy 2018 Apr;34(4):1052-1053

La Jolla, California.

The increasing interest and use of cartilage repair procedures in the knee has led to a better understanding of when and how chondral lesions should be treated. Nonetheless, there are still key areas where we lack understanding and need better data to guide clinical decision making. One of these areas is how to manage lesions of the tibia, particularly when they occur in conjunction with the more commonplace lesions of the femoral condyle. Read More

Department of Trauma Surgery, University Medical Center Regensburg, Regensburg, Germany.

Articular cartilage predominantly serves a biomechanical function, which begins in utero and further develops during growth and locomotion. With regard to its 2-tissue structure (chondrocytes and matrix), the regenerative potential of hyaline cartilage defects is limited. Children and adolescents are increasingly suffering from articular cartilage and osteochondral deficiencies. Read More

Cartilage Restoration: Microfracture and Osteochondral Autograft Transplantation.

J Knee Surg 2018 Mar 2;31(3):231-238. Epub 2018 Feb 2.

Department of Orthopaedic Surgery, Rush University Medical Center, Chicago, Illinois.

The treatment of patellofemoral cartilage defects presents several distinct challenges when compared with cartilage restoration techniques used for other compartments of the knee due to the unique anatomy and distribution of forces. The etiologies of patellofemoral articular cartilage lesions include acute traumatic instability injuries, such as dislocation and subluxation, osteochondritis dissecans, and chronic degenerative changes. Regardless of the etiology, untreated patellofemoral cartilage lesions can contribute to activity-limiting anterior knee pain. Read More

Authors:
Kathryn L Bauer

J Knee Surg 2018 May 30;31(5):382-391. Epub 2018 Jan 30.

Pediatric Orthopaedics and Sports Medicine, Children's Health Andrews Institute for Orthopaedics and Sports Medicine, Plano, Texas.

Osteochondral injuries in pediatric patients may occur as a result of a traumatic injury or secondary to an osteochondritis dissecans (OCD) lesion. Lateral patella dislocation is a common traumatic cause of osteochondral injury that typically occurs at the medial facet of the patella or at the lateral aspect of the distal femur. Multiple theories have been proposed for the cause of an OCD lesion in the knee, including trauma or repetitive microtrauma, local vascular insufficiency, and family history. Read More
