For these patients, the goal is not to repair the injury, but to reduce pain and improve function. These patients will often require another procedure at a later time to address the cartilage lesion formally. In contrast to palliative care, other techniques seek to stimulate cartilage regeneration and/or replace lost cartilage with cartilage transplants or synthetic materials. Microfracture, the first efforts to address cartilage injury focused on getting the body to produce new articular cartilage as a response to injury to the subchondral bone; a form of the technique, microfracture, is still widely used and is, in fact, the current standard. With microfracture, the surgeon creates tiny holes or fractures in the underlying subchondral bone in the damaged area. The holes allow clots to form (in response to the injury over time, the clots change into a cartilage tissue. Figure 4: Arthroscopic view showing the articular cartilage surface following microfracture *Note the tiny holes in cartilage. While microfracture has resulted in the generation of new cartilage tissue in thousands of patients, orthopedic surgeons and researchers have continued to look for methods that would result in more durable repair. Although a number of studies at hss have demonstrated the efficacy of microfracture,.
This advanced mri technology has been tremendously useful to orthopedic surgeons in detecting articular cartilage lesions before surgery and objectively assessing articular cartilage repair methods in treated patients following surgery over time. The use of cartilage sensitive mri is a de facto part of my postoperative regimen in patients treated for articular lesions, says. These images allow me to objectively assess the programul success of my surgical efforts in creating cartilage-repair material in an area which was devoid of any cartilage before the surgery. I can correlate what I see on these mris and what i observe clinically in the patients recovery and use this nackenverspannung information to appropriately adjust the patients postoperative care and rehabilitation. Figure 3: mri showing a healed osteochondral allograft.
Treatment Options, treatment recommendations for articular cartilage injury are based on a variety of factors, including the patients age, patient activity level, overall condition of the joint, the size and location of the lesion, the patients ability to participate in rehabilitation, and whether the patient. Hospital for Special Surgery cares for many professional and collegiate teams, and as a result, surgeons at the Institute are very focused on return to sport as an endpoint in assessing their success in the area of cartilage repair. Treatment options vary from patient to patient, depending on the situation. Palliative care, in some cases, the orthopedic surgeon will recommend palliative care, in which he or she removes the loose fragments of cartilage or meniscus that might cause a mechanical block and joint pain. While palliative care does not address the issue of articular cartilage fill or repair as an objective of the surgery, we often recommend this as a short-term approach for athletes who are in-season and face time pressures to return to sport as soon as possible. Such procedures are usually minimally invasive, and athletes can return to sport within four to six weeks.

Magnetic Resonance Imaging (MRI) to assess the nature of a cartilage injury and formulate a treatment strategy. At hss, sophisticated mri techniques provide images in which cartilage is clearly distinguished from bone. As recently as a decade ago, most imaging modalities did not provide information on the structure and state of articular cartilage. As a result, surgeons had to rely on direct observation during an operation rather than obtaining it in advance. This often resulted in patients therapie receiving suboptimal treatment, as the treatment of these undetected lesions had not been discussed with patients prior to their operative procedure. Fortunately, surgeons at hss have benefitted from the efforts of their colleagues in the. Department of Radiology in this area. Led by, hollis Potter, md, mri technology has been at the forefront of articular cartilage imaging for many years.

In healthy joints, this unique and durable material allows bones to move against one another with minimal friction. Figure 1 (Left view of a normal knee joint through an arthroscope, showing smooth articular cartilage and the meniscus. Figure 2 (right Arthroscopic view of a joint surface showing a full thickness defect of articular cartilage exposing underlying subchondral bone. When areas hoofdpijn of cartilage are worn away or torn away, exposing underlying (subchondral) bone, treatment is designed to fill in the missing area or defect with healthy articular cartilage and provide new protection for the joint surface. Orthopedists categorize the severity of cartilage injury using the outerbridge Classification system, a scale from 0 to 4, with 0 being normal and grade 4 being complete exposure of the subchondral bone. Most of the patients treated at the Institute for Cartilage repair have a grade 3 or 4 injury. Most symptomatic cartilage lesions are at least 2 cm in diameter, but may often be as small as 1 cm in diameter or as large as 4 cm in size. These areas of cartilage loss interfere with normal joint mechanics, and result in pain and poor joint function in affected individuals. Diagnosis, in addition to patient history and physical evaluation, orthopedic surgeons rely.
Articular Cartilage: What Is It? Whether the cause is trauma or disease, damage to articular cartilage - the smooth cushion treatment that lines the end of the bones where they meet at the joints - can cause significant pain and weakness. Because of the bodys limited ability to regenerate articular cartilage cells, injuries to this highly specialized tissue can result in significant and progressive damage to the joint surface, says. Williams, md, iii, associate attending orthopedic surgeon at hss. . If left untreated, these localized areas of cartilage damage and loss may rapidly spread to involve the entire joint surface, an end result known as osteoarthritis of the joint. To better understand these injuries and their treatment, it may be helpful to describe the structure of articular cartilage. Articular cartilage lines the ends of our joint surfaces and is composed of cells called chondrocytes with a matrix or scaffolding made of collagen and proteins.
