The main advantages over autograft transplantation are the ability to closely match the curvature of the articular surface by harvesting the graft from a corresponding location in the donor condyle, the ability to transplant large grafts, and the avoidance of donor-site morbidity. Restorative cartilage repair techniques such as autologous chondrocyte implantation (ACI) introduce chondrogenic cells into the defect area, resulting in the formation of a repair tissue that more closely resembles the collagen type-II rich hyaline cartilage. An allograft is usually used when cartilage defect being treated is too large for an autograft (≥2cm). When filling osteochondral defects in the knee, surgeons have a list of treatment options to choose from and more options are in the works. You are currently offline. It originally received FDA approval for application in the femoral condyle (medial, lateral, and trochlea) but has also been used successfully to treat patellar defects. The cause of a cartilage defect can be due to trauma, osteonecrosis, osteochondritis, and other conditions.Cartilage defects are most commonly seen in the knee joint, where it is often caused by trauma and seen in association with ligament injuries, such as ACL tears. In conclusion, treatment of early knee osteoarthritis and chondral lesions is still a challenging problem. Within the ankle, these lesions often occur on the talus, which is the bone that joins the foot and the leg together. Within the knee, cartilage damage can happen between the thigh bone and the shinbone. Surgical options range from simple fragment excision to internal fixation of the fracture fragment to more complex cartilage restoration or replacement procedures. This special focus section will discuss the diagnosis and treatment options for traumatic osteochondral knee injuries, including the subset secondary to juvenile OCD lesions. The next generation ACI-c (collagen-covered) technique was developed to reduce the reoperation rate because of hypertrophy of the periosteal patch used to cover the defect. Regardless, each osteochondritis dissecans lesion must be followed until osseous integration is confirmed by imaging -otherwise, progression of disease to osteoarthritis is likely.” Yoshimura I, Kanazawa K, Takeyama A, et al. Author information: (1)Sport Medicine and Knee Research Center, Milad Hospital, Tehran, Iran. What Are the Best Diagnostic Criteria for Lateral Epicondylitis? Osteochondral allograft transplantation uses cartilage from outside the patient, usually from a cadaver. Microfracture treatment results in better outcomes in younger patients (<30–40 years old). TREATMENT OPTIONS. Arthroscopic Treatment of Osteochondral Lesions of the Talus Steven M. Raikin, MD John J. Mangan, MD Dr. Raikin or an immediate family member has received research or institutional support from Zimmer. Purpose: Surgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants.A treatment gap exists for patients with lesions not suitable for arthroplasty or biologic repair or who have failed prior cartilage repair surgery. Osteochondral allograft transplantation is used predominantly in the treatment of large and deep osteochondral lesions resulting from OCD, osteonecrosis, and traumatic osteochondral fractures, but it can also be used to treat peripherally uncontained cartilage and bone defects.

Chapter 96 What Is the Best Treatment for Chondral Defects in the Knee? Marrow stimulation techniques (MST), such as abrasion arthroplasty, drilling, and microfracture, attempt to induce a reparative response by perforation of the subchondral bone after radical debridement of damaged cartilage and removal of the tide mark “calcified” zone to enhance the integration of repair tissue. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. Most studies show good outcomes in 60% to 80% of patients. Treatment may include activity modification, drilling, fixation, or osteochondral replacement of osteochondritis dissecans lesions in the knee. Depth: the depth of a defect is a consideration in selection of treatment, and if there is underlying bone loss beneath the cartilage defect then this may need to be restored. Treatment options for diffuse PVNS can be arthroscopic excision, open synovectomy, combined arthroscopic and open synovectomy, with or without adjuvant radiotherapy. Recent MR scanning techniques such as MR arthrography, magnetization transfer imaging, and fast spin echo sequences have improved the visualization of chondral defects. Pain with weight bearing activities The conservative treatment of OCLs of the talus is limited for stages I and II only. 12. If you've injured your joint and your symptoms are not too severe – for example, you're still able to put weight on and move the joint – you can often look after yourself using PRICE therapy. ACI is indicated for the treatment of medium to large chondral defects with no or shallow associated osseous deficits. Some osteochondral lesions are asymptomatic and may be incidentally found whilst imaging the knee for other ... surgery or open surgery depending upon the type of lesion involved. The original technique of ACI was developed in the 1980s7 and has been used in the United States to treat more than 10,000 patients since its approval by the U.S. Food and Drug Administration (FDA) in 1997. CONCLUSION: Osteochondral allograft transplantation is a useful salvage treatment option for reciprocal bipolar cartilage lesions of the knee. Kreuz and Erggelet. Simple arthroscopic lavage and debridement of lesions has been used since the 1940s in an effort to reduce symptoms resulting from loose bodies and cartilage flaps, and it is a common first-line treatment, especially for coincidental defects. TREATMENT OPTIONS FOR JUVENILE OSTEOCHONDRAL KNEE DEFECTS D Crisan 1,2, D Vermesan 1,2, R Prejbeanu 1,2, S Nitescu 2, C Bogdan 2 Abstract Articular cartilage is a avascular, aneural and alymphatic tissue that covers the articular ends of bones. BACKGROUND: Autologous osteochondral transplantation (AOT) has been shown to be a viable treatment option for large osteochondral lesions of the talus. PRICE stands for: Protection – protect the affected area from further injury by using a support, such as a knee brace 10.1055/b-0034-92488 The Use of Scaffolds in the Treatment of Osteochondral Lesions in the Knee: Current Concepts and Future TrendsAad A. M. Dhollander, Victor R. Guevara Sánchez, Karl F. Almqvist, René Verdonk, Gust Verbruggen, and Peter C. M. Verdonk The treatment of chondral and osteochondral lesions has become a major interest to orthopedic surgeons because most… Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm, The treatment of chondral defects with fresh osteochondral allografts has garnered significant attention because of its potential to restore and resurface even extensive areas of damaged cartilage and bone. This joint permits much of the up (dorsiflexion) and down (plantarflexion) motion of the foot and ankle. Osteochondral cylinders are harvested from lesser marginal weight-bearing areas of the knee joint and press-fitted into the prepared defect. The main advantages over autograft transplantation are the ability to closely match the curvature of the articular surface by harvesting the graft from a corresponding location in the donor condyle, the ability to transplant large grafts, and the avoidance of donor-site morbidity. Neither Dr. Mangan nor any immediate family member has received anything of value from or has stock or stock options held in a commercial… Treatment Options Articular cartilage has no blood supply and its ability to repair itself is poor. Treatment of chondral and osteochondral lesions of the patellofemoral (PF) joint is complex as it typically must address the multifactorial etiology. Arthroscopic bone marrow stimulation techniques for osteochondral lesions of the talus: prognostic factors for small lesions. We can confirm the effect of mosaicplasty on the improvement of patients with osteochondral lesions of the ankle, suggesting it as a treatment option. Is There a Role for Arthroscopy in the Treatment of Knee Osteoarthritis. Osteochondral lesions, sometimes called osteochondritis dessicans or osteochondral fractures, are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. The latest generation of ACI, termed MACI (membrane associated), cultures the chondrocytes directly on the aforementioned collagen membrane, which is then implanted arthroscopically or through a mini-open approach with fibrin glue or limited suturing. Cartilage lesions of the knee are rather common in children and adolescents representing a more difficult pathological entity due to the young age of the patients and the risk of secondary degenerative…, Management of Osteochondritis Dissecans of the Knee, Surgical Treatment Options for Osteochondritis Dissecans of the Knee. A large knee osteochondral lesion treated using a combination of osteochondral autograft transfer and second-generation autologous chondrocyte implantation: A case report Regen Ther . Cartilage replacement techniques include osteochondral autograft and allograft transfers, such as the osteochondral autograft transfer system (OATS; Arthrex, Naples, FL), mosaicplasty (Smith & Nephew, Andover, MA), and mega-OATS techniques. 1 Treatment options … This special focus section will discuss the diagnosis and treatment options for traumatic osteochondral knee injuries, including the subset secondary to juvenile OCD lesions. Patients are approximately evenly split in reporting a traumatic versus an insidious onset of symptoms; athletic activities are the most common inciting event associated with the diagnosis of a chondral lesions.1 Traumatic events and developmental causative agents such as osteochondritis dissecans (OCD) predominate in younger age groups. Am J Sports Med. 7 The depth of the lesion can be categorized according to the International Cartilage Regeneration & Joint Preservation Society (ICRS) grading system (). Treatment of osteochondral injuries and osteochondritis dissecans (OCD) is … These injuries may include blistering of the cartilage layers, cyst-like lesions within the bone underlying the cartilage, or fracture of the cartilage and bone layers. However due to its poor vascularization it has rather limited regenerative capabilities. This approach allows planning an appropriate course of treatment. It serves as al low friction high wear resistance surface to ideal provide mobility and strength. Several studies have tried to define the indications for microfracture in regards to patient and defect characteristics. Treatment. Knee osteochondral fractures in skeletally immature patients: French multicenter study. The widely published treatment strategies of symptomatic osteochondral lesions include the non-surgical treatment with rest or cast immobilization, and surgical excision of the lesion, excision and curettage, excision combined with Buy Membership for Orthopaedics Category to continue reading. What Is the Best Treatment for End-Stage Hallux Rigidus? Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm 2), often with associated bone loss. The high costs and extensive rehabilitation associated with many of these procedures necessitate careful evaluation to establish their respective clinical and cost-effectiveness. 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. High-quality outcomes research is necessary to provide a better understanding of the efficacy of these procedures and to enable physicians to properly indicate treatment. Sabaghzadeh A(1), Mirzaee F(1), Shahriari Rad H(1), Bahramian F(1), Alidousti A(2), Aslani H(3). The blood supply to the talus is not as rich as many other bones in the body, and as a result injuries to the talus sometimes are more difficult to heal than similar injuries in other bones. Osteochondral defects are amenable to osteochondral allograft transplantation. Commonly, multiple cylinders have to be transplanted to fill larger defects. Issue: ... have been described as suitable treatment options. Simple arthroscopic lavage and debridement of lesions has been used since the 1940s in an effort to reduce symptoms resulting from loose bodies and cartilage flaps, and it is a common first-line treatment, especially for coincidental defects. Abrasion arthroplasty (or also abrasion chondroplasty) decorticated the superficial subchondral bone with a bur to expose the more porous bone below but also destabilized the subchondral bone with the risk for fracture. Restorative cartilage repair techniques such as autologous chondrocyte implantation (ACI) introduce chondrogenic cells into the defect area, resulting in the formation of a repair tissue that more closely resembles the collagen type-II rich hyaline cartilage. Table 96-1 provides an overview of cartilage repair studies. Five surgical procedures to manage OCD lesions in the knee. The resultant blood clot, and the primitive mesenchymal cells contained within, may differentiate into a fibrocartilaginous repair tissue that fills the defect. Furthermore, osteochondral allografting presents a viable salvage option after failure of other cartilage resurfacing procedures. ACI, autologous chondrocyte implantation; ACI-c collagen-covered autologous chondrocyte implantation; BMI, body mass index; MACI, membrane-associated autologous chondrocyte implantation. It serves as al low friction high wear resistance surface to ideal provide mobility and strength. Current surgical treatments, such as microfractures, ACI and OAT, are the best options available, though it could be hard to increase the use of ACI and OAT because of similar results and higher costs, if compared with MF. The original technique of ACI was developed in the 1980s, Cartilage replacement techniques include osteochondral autograft and allograft transfers, such as the osteochondral autograft transfer system (OATS; Arthrex, Naples, FL), mosaicplasty (Smith & Nephew, Andover, MA), and mega-OATS techniques. Osteochondral autograft transfer (mosaicplasty) for treatment of patients with osteochondral lesions of talus. TABLE 96-1 Overview of Cartilage Repair Studies, TABLE 96-2 Treatment Recommendations and Respective Level of Evidence. Patients are approximately evenly split in reporting a traumatic versus an insidious onset of symptoms; athletic activities are the most common inciting event associated with the diagnosis of a chondral lesions. Kreuz and Erggelet10, Evidence-Based Orthopaedics The Best Answers to Clinical Questio. Articular cartilage is a avascular, aneural and alymphatic tissue that covers the articular ends of bones. Osteochondral Defect is the name given to a condition most noticeable in the knee, in which a part of the bone and cartilage gets separated from the knee joint resulting in chronic pain in the knee and difficulties performing normal activities of daily living.
