Because of the relatively high cost of ACI and the knee morbidity seen in OATS, we conclude that BMS is the treatment of choice for primary osteochondral talar lesions. You may need to wear a cast or walking boot to restrict certain movements, but most of this treatment focuses on limiting sports and heavy activity. Commonly, multiple cylinders have to be transplanted to fill larger defects. * to detect the most effective treatment option for primary talar osteochondral defects in adults. * It is known from long-term followup studies, such as those conducted by Linden, 7 that osteochondritis dissecans diagnosed in adulthood is likely to lead to the development of early onset osteoarthritis. This may be useful to alle… The use of minced articular cartilage for the repair of osteochondral articular cartilage defects of the knee is considered experimental and investigational. Unless the injury is extensive, it may take months, a year or even longer for symptoms to develop. The purpose of this article is to give an overview of the treatment options available for osteochondral defects in the knee and to propose a treatment algorithm based on the senior author's (WGC) experience. For instance, if the anterior cruciate ligament were to rupture, the tibia can slide forward (subluxate) and impact the femoral condyle (a so-called kissing contusion). This allows us to treat the bone defect without affecting the cartilage. Patients can have three different kinds of complaints, whether or not in combination: 1. A preliminary report. An osteochondral defect refers to a focal area of damage that involves both the cartilage and a piece of underlying bone. Treatment options to restore joint congruity vary widely from nonoperative closed treatment to arthroscopic drilling, with or without fixation, to tissue transplantation or reconstructive procedures. The transplantation of autologous hyaline cartilage plugs results in a hyaline cartilage base with fibrocartilage “grout.”40 Mosaicplasty is designed for the treatment of focal chondral and osteochondral defects of the knee in patients under 45 years of age.

Knee Surg Sports Traumatol Arthrosc 5(4):262–267 PubMedCrossRef Hangody L, Kish G, Karpati Z, Szerb I, Udvarhelyi I (1997) Arthroscopic autogenous osteochondral mosaicplasty for the treatment of femoral condylar articular defects. Large, focal articular cartilage defects of the knee (> 4 cm) can be a source of significant morbidity and often require surgical intervention. Treatment depends upon the size of the osteochondral defect and the condition of the overlying cartilage. Background: Mosaicplasty and fresh osteochondral allograft transplantation (OCA) are popular cartilage restoration techniques that involve the single-stage implantation of viable, mature hyaline cartilage-bone dowels into chondral lesions of the knee. This case report presents a massive OCD with displaced osteochondral fragment and loose body in the knee joint that occupied almost all of the weight bearing area of the medial femoral condyle and was treated with concomitant osteochondral autograft transplantation and fixation of displaced osteochondral fragment. The fixed sutures on the femoral surface did not have much effect on the joints, and the patients did not feel any discomfort. Prior surgical therapy to correct the defect has been unsuccessful 2.

James L. Chen, MD, (San Francisco, CA) provides a case presentation of a patient with an osteochondral lesion of the lateral femoral condyle. Trauma, osteochondritis dissecans, osteonecrosis, osteochondroses, and hereditary epiphyseal abnormalities can cause osteochondral lesions in the knee joint.25, 61, 62, 72 When an osteochondral defect persists in a weightbearing portion of the knee joint, degenerative arthritis of that compartment can result. However, due to great diversity in the articles and variability in treatment results, no definitive conclusions can be … Terminology. Knee microfracture surgery is a common surgical procedure used to treat the surfaces of the knee joint when they have become damaged. The type of surgery that is most effective depends on the size, location and severity of the lesion. Chondral and osteochondral defects in the PF compartment are often encountered in clinical practice on advanced imaging studies and/or during arthroscopy.

In conclusion, treatment of early knee osteoarthritis and chondral lesions is still a challenging problem.

Osteochondral defects generally linger or get worse unless they’re treated. Ideally, defects of the articular cartilage in the knee would be replaced with normal hyaline cartilage. Treatment options to restore joint congruity vary widely from nonoperative closed treatment to arthroscopic drilling, with or without fixation, to tissue transplantation or reconstructive procedures. Damage to the surface of the knee joint is commonly caused by osteochondral lesions. For small-sized defects with intact cartilage, our treatment of choice is Retrograde Drilling of the lesion and filling it with a special bone cement. Osteochondral cylinders are harvested from lesser marginal weight-bearing areas of the knee joint and press-fitted into the prepared defect. Kon E. et al. Treatment was indicated for patients with symptomatic chondral and osteochondral defects in the knee who had failed conservative treatment and who were suitable for the procedure as determined on specific MRI imaging and satisfactory mapping according to an individualised damage marking report.
