Osteochondritis Dissecans of the Knee: Pearls and Pitfalls of Anatomical Reduction and Secure Fixation.

ABSTRACT: Osteochondritis dissecans of the knee is characterized by sterile necrosis of the subchondral bone and typically affects skeletally immature patients. When left untreated, osteochondritis dissecans can lead to early-onset osteoarthritis, resulting in pain and disability. This study shows the pearls and pitfalls of an arthroscopic technique of fixation performed successfully using a bioabsorbable nail for unstable osteochondritis dissecans lesions located in the medial femoral condyle of the knee.

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 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.

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.

Open Treatment for Unstable Osteochondritis Dissecans of the Knee: Autologous Bone Grafting and Bioabsorbable Fixation.

Project description:Osteochondritis dissecans is a common osteochondral abnormality affecting the knee. In unstable lesions, the underlying bone can be significantly abnormal and necessitate treatment. Although many techniques exist, we favor an open surgical approach to ensure that the bone is properly managed. Autologous bone graft can easily be obtained locally and used to restore the bony architecture. The subsequent use of bioabsorbable implants provides a robust means of fixation that allows for single-stage surgery. This Technical Note describes a straightforward but reliable approach to a challenging pathology.

Internal Fixation of Osteochondritis Dissecans Using PushLock Suture Anchors.

Project description:Osteochondritis dissecans (OCD) of the knee is a subchondral bone abnormality that results in the separation of the articular cartilage and bone with subsequent progression to osteoarthritis. Unstable OCD lesions should undergo fixation to preserve the natural contour of the articular surface. Although several fixation procedures have been reported, the appropriate procedure remains unknown. Because the bony portion of the OCD lesion is usually thin, it is difficult to fix firmly with conventional methods. We began fixing OCD lesions with knotless PushLock anchors and sutures and have obtained satisfactory results. This report describes this fixation method that uses the PushLock suture anchor to treat unstable OCD lesions. This procedure also can be applied for traumatic osteochondral fractures.

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.

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

Project description: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. Previous studies have demonstrated excellent outcomes in patients undergoing fixation for unstable chondral lesions not amenable to conservative treatment. A critical component of successful treatment is understanding the importance of hardware placement and technique. The purpose of the Technical Note is to describe a method performing this 2-stage arthroscopic repair of an unstable chondral lesion located on the medial femoral condyle of the knee.

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.
