The golf ball sign: arthroscopic localization of an osteochondritis dissecans lesion of the knee.

ABSTRACT: We report on the arthroscopic treatment of a 12-year-old boy diagnosed with an osteochondral defect of the medial femoral condyle. He underwent arthroscopic fixation of the defect, and during the surgery, a blunt trocar was used to localize the lesion. The trocar created a transient dimpling effect on the cartilage overlying the osteochondral defect that resembled the surface of a golf ball. This "golf ball sign" then served as a visual guide during placement of a chondral dart. When present, it is believed that this sign can benefit arthroscopists by helping to improve intraoperative localization of an osteochondral defect.

Arthroscopic preparation and internal fixation of an unstable osteochondritis dissecans lesion of the knee.

Project description:We present our arthroscopic technique for fixation of an unstable osteochondritis dissecans (OCD) lesion. This technique includes arthroscopic evaluation of cartilage and bone quality of the OCD fragment, hinging open the lesion, debridement of fibrous nonunion tissue, reducing the fragment, and obtaining multi-point compression screw fixation. This technique avoids the morbidity of an open arthrotomy and should be considered when treating an unstable OCD lesion with adequate bone for fixation.

Osteochondritis Dissecans of the Knee: Arthroscopic Suture Anchor Fixation.

Project description:Osteochondritis dissecans (OCD) is a subchondral bone abnormality, in which subchondral bone and the overlying articular cartilage detach from the bony bed. Multiple techniques for OCD fixation have been described, including metallic, bioabsorbable implants and biological fixation. We describe a surgical technique for OCD lesions including bony bed preparation with curettage and microfracture, anatomic reduction, and fixation using a suture anchor to provide stability and healing of the lesion.

Arthroscopic Fixation of Knee Osteochondritis Dissecans With Interlinked Knotless All-Suture Anchors.

Project description:Unstable, displaced, and persistently symptomatic osteochondritis dissecans of the knee typically requires surgical treatment. An arthroscopic, knotless fixation method using interlinked all-suture anchors is presented, with potential advantages over other current techniques in fixation over a broad zone, treatment versatility for a wide range of fragment types, retensioning ability after stressing, decreased risk of implant-breakage complications, and avoidance of additional surgery for implant removal.

Arthroscopic Fixation of Knee Femoral Condyle Osteochondritis Dissecans Fragment With Bone Marrow Aspirate Concentrate.

Project description:This article reviews a technique for arthroscopic fixation of an osteochondritis dissecans fragment with bone marrow aspirate concentrate augmentation. This technique involves safe harvest of bone marrow arthroscopically from the intercondylar notch, proper preparation and debridement of the parent bone, reduction of the progeny osteochondritis dissecans fragment, insertion of the bone marrow aspirate concentrate, and placement of multiple headless compression screws for fixation.

All-Arthroscopic Suture Fixation of Patellar Osteochondritis Dissecans.

Project description:Osteochondritis dissecans of the knee, despite its cause, is characterized by the impairment of the subchondral bone. Failure of its spontaneous healing makes surgical fixation often necessary. The patella is less affected than other locations in the knee. Its surgical treatment remains a challenge due to the thickness of the lesion and the complex approach of the retropatellar cartilage. Arthroscopy has the theoretical advantage to avoid a possible arthrotomy; however, the retrograde application of fixation materials does not guarantee good fragment compression and may lead to cartilage penetration and damage. The purpose of this Technical Note is to present a reproducible, full arthroscopic suture fixation technique for patellar osteochondritis dissecans lesions. By using the posterior cruciate tibial drill guide, absorbable sutures are passed through the center and the peripheral borders of the lesion resulting in a "spider-parachute-type" fixation with direct fragment compression.

Arthroscopic Microfracture for Osteochondritis Dissecans Lesions of the Capitellum.

Project description:Capitellar osteochondritis dissecans (OCD) is one of the most common causes of elbow pain and dysfunction in adolescent athletes. It typically occurs in gymnasts and overhead throwers and presents along a wide spectrum of severity. Stable lesions can typically be treated with conservative therapy; however, those presenting with instability, fragmentation, or loose bodies generally require surgical intervention. Although there are a number of described surgical options used to treat capitellar OCD lesions, microfracture is one of the most commonly performed and well studied. Patients who are candidates for microfracture generally have favorable outcomes with high rates of return to athletic activity after postoperative rehabilitation. In this work, we present our preferred arthroscopic technique for microfracture of OCD lesions of the capitellum. This technique is most suitable for patients with unstable or fragmented OCD lesions that are less than 1 cm in diameter and do not violate the lateral-most articular margin of the capitellum.

Arthroscopic Fixation of Osteochondritis Dissecans of the Knee Using a Motorized Pick and Headless Compression Screws.

Project description:Osteochondritis dissecans (OCD) of the knee affects children and adolescents. The condition is characterized by sterile osteonecrosis of the subchondral bone. The cause is unknown. OCD is divided into juvenile or adult type, depending on whether the physis is open or closed at the time of diagnosis. Stable juvenile OCD lesions have substantial healing potential and are treated conservatively, with a healing potential of up to 75%. However, in unstable lesions and in all symptomatic adult OCD lesions, surgical treatment is indicated. The purpose of this article was to present our method of arthroscopic fixation of an unstable OCD in the knee, using a motorized pick to stimulate the bed of the lesion, and firm fixation with headless screws. The advantage of this method is the controlled and meticulous debridement and stimulation of the sclerotic necrosis behind the OCD fragment and the firm compression achieved with the screws, enabling an intensive and early rehabilitation.

Arthroscopic Autologous Chondrocyte Transplantation for Osteochondritis Dissecans of the Elbow.

Project description:Osteochondritis dissecans of the humeral capitellum is characterized by separation of a circumscript area of the articular surface and the subchondral bone in juvenile patients. In advanced lesions, arthroscopic fragment refixation or fragment removal with microfracturing or drilling can be successful. The purpose of this technical note is to describe an all-arthroscopic surgical technique for 3-dimensional purely autologous chondrocyte transplantation for osteochondral lesions of the humeral capitellum.

Extra-articular, Intraepiphyseal Drilling for Osteochondritis Dissecans of the Knee.

Project description:Symptomatic osteochondritis dissecans lesions of the knee frequently occur in skeletally immature patients. When conservative treatment fails, retro-articular drilling, also known as intraepiphyseal extra-articular drilling, becomes a viable treatment option. The purpose of this article is to describe our surgical technique and postoperative management of patients with stable osteochondritis dissecans lesions involving the femoral condyles. This technique is reproducible, uses readily available equipment, and has yielded good clinical outcomes with high healing rates and relatively early return to sports.

All-Arthroscopic Osteochondral Autograft Transfer Technique for Osteochondritis Dissecans of the Talus.

Project description:Juvenile osteochondritis dissecans of the talus can be a challenging condition to treat in young patients. Previously described osteochondral autograft transfer techniques for medial talar lesions have been done via open approach, often requiring medial malleolus osteotomy. The purpose of this article is to present an all-arthroscopic osteochondral autograft transfer technique for a medial talar osteochondritis dissecans lesion in a skeletally immature patient.
