A Staged Arthroscopic Approach to Fixation of Unstable Osteochondritis Dissecans in the Medial Femoral Condyle of the Knee Using Nonabsorbable Fixation Screws.

Arthrosc Tech 2020 Apr 10;9(4):e477-e481. Epub 2020 Mar 10.

Division of Sports Medicine, Department of Orthopedic Surgery, Wake Forest Baptist Health, Winston-Salem, North Carolina, U.S.A.

Osteochondritis dissecans is a focal lesion of articular cartilage that can result in fragment instability with progression of early osteoarthritis. Regarding the knee joint, salvage of an unstable lesion can be achieved using arthroscopic-assisted reduction and fixation via a 2-stage process. The first involves arthroscopic fixation of the fragment using nonbioabsorbable screws, whereas the second stage performed 12 weeks later involves removal of the screws and confirmation of successful healing of the lesion.

Measuring Knee Bone Marrow Perfusion Using Arterial Spin Labeling at 3 T.

Sci Rep 2020 Mar 24;10(1):5260. Epub 2020 Mar 24.

Center for Magnetic Resonance Research, University of Minnesota, Minneapolis, MN, USA.

Bone perfusion is an essential physiological measure reflecting vasculature status and tissue viability of the skeletal system. Arterial spin labeling (ASL), as a non-invasive and non-contrast enhanced perfusion imaging method, is an attractive approach for human research studies. To evaluate the feasibility of ASL perfusion imaging of knee bone marrow in the distal femoral condyle at a 3 T MRI scanner, a study was performed with eight healthy volunteers (three males and five females, 26 ± 2 years old) and two patients (male, 15 and 11 years old) with diagnosed stage II juvenile osteochondritis dissecans (JOCD).

Editorial Commentary: Osteochondritis Dissecans of the Knee: The Great Confounder.

Authors:
Eric W Edmonds

Arthroscopy 2020 03;36(3):795-796

University of California San Diego.

The management of osteochondritis dissecans (OCD) continues to baffle even the savviest of surgeons, with unclear etiology, unknown relationship of presentation to outcome, bewildering response to various treatments, and frustratingly difficult-to-predict prognosis. Whether skeletal immaturity may be indicative of surgical success, at least when it comes to lesions requiring screw fixation, remains debatable. Treatment may include activity modification, drilling, fixation, or osteochondral replacement of OCD lesions in the knee. Read More

J Biomech 2019 Nov 13;96:109333. Epub 2019 Sep 13.

National Institute for Occupational Safety and Health, Morgantown, WV, USA.

Epidemiological studies indicate that occupational activities that require extended deep knee flexion or kneeling are associated with a higher prevalence of knee osteoarthritis. In many sport activities, such as a catcher in a baseball or a softball game, athletes have to make repetitive deep squatting motions, which have been associated with the development of osteochondritis dissecans. Excessive deep knee flexion postures may cause excessive loading in the knee joint. Read More

A new systematic review concludes that internal fixation of unstable OCDs in adults leads to good function, and the healing rates are more than acceptable. That's a good thing; keep on fixing those OCDs. Read More

Fresh Osteochondral Allograft Transplantation for Uncontained, Elongated Osteochondritis Dissecans Lesions of the Medial Femoral Condyle.

Arthrosc Tech 2019 Mar 11;8(3):e267-e273. Epub 2019 Feb 11.

Department of Orthopaedic Surgery, Sports Medicine and Shoulder Service, Hospital for Special Surgery, New York, New York, U.S.A.

Osteochondritis dissecans (OCD) lesions of the knee are a significant source of pain and disability. Although the pathologic process for this condition remains poorly understood, histologic studies suggest vascular insufficiency of the subchondral bone may be the underlying cause for focal necrosis and subsequent compromise of the overlying articular cartilage. These lesions most commonly affect the medial femoral condyle and can be found along the margins of the intercondylar notch. Read More

Advanced Orthopaedics and Sports Medicine, San Francisco, California, U.S.A.

Osteochondritis dissecans (OCD) has been recognized for over 100 years yet still poses treatment challenges owing to both the avascular nature of articular cartilage and the inability to generate hyaline cartilage. The knee is most commonly involved, and without repair, patients have chronic knee pain, loose bodies, and early-onset osteoarthritis. There are a number of surgical techniques for repairing OCD, some of which are still being refined. Read More
