Issue: ... have been described as suitable treatment options. 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… 13. 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. Surgical options range from simple fragment excision to internal fixation of the fracture fragment to more complex cartilage restoration or replacement procedures. This was achieved by substitution of periosteum with a collagen membrane, frequently consisting of a porcine type-I/III collagen bilayer membrane. Should Patella Be Resurfaced in Total Knee Replacement? The conservative treatment of OCLs of the talus is limited for stages I and II only. Drilling utilizes small drill bits or K-wires to perforate the subchondral bone, which can result in heat necrosis; microfracture avoids this issue by using special awls (microfracture or Steadman awls). 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. 2020 Feb;23(1):60-62. doi: 10.1016/j.cjtee.2019.12.001. Several studies have tried to define the indications for microfracture in regards to patient and defect characteristics. Most studies show good outcomes in 60% to 80% of patients. Treatment of juvenile osteochondritis dissecans and osteochondritis dissecans of the knee. BACKGROUND: Autologous osteochondral transplantation (AOT) has been shown to be a viable treatment option for large osteochondral lesions of the talus. Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm 2), often with associated bone loss. It serves as al low friction high wear resistance surface to ideal provide mobility and strength. Much of this bone is covered with cartilage. 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. An osteochondral lesion may also be known as an osteochondral defect. What Is the Best Surgical Treatment for Early Degenerative Osteoarthritis of the Wrist? 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. Several large studies have found high-grade chondral lesions (Outerbridge grades III and IV) in 5% to 11% of younger patients (<40 years) and up to 60% of older patients.1–3 The most common locations for these defects are the medial femoral condyle (up to 32%) and the patella,2,3 and most are detected incidentally during meniscectomy or anterior cruciate ligament reconstruction.1,4 Notably, despite this relatively high incidence, many of these defects are incidental in nature and asymptomatic. Am J Sports Med. Currently, to our knowledge, there are no data regarding which MRI features may predict improved outcomes in these patients. Damage to the articular cartilage comprises a spectrum of disease entities ranging from single, focal chondral defects to more advanced degenerative disease. Although wearing a brace or cast may ease the discomfort of an osteochondral lesion, they are usually not enough to remedy the problem permanently, except in children, who can respond well to … Within the ankle, these lesions often occur on the talus, which is the bone that joins the foot and the leg together. Buy Membership for Orthopaedics Category to continue reading. 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 Articular cartilage is a avascular, aneural and alymphatic tissue that covers the articular ends of bones. 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. ACI in its current form is a two-stage procedure with an initial arthroscopic cartilage biopsy, followed by a staged reimplantation through an arthrotomy. Sabaghzadeh A(1), Mirzaee F(1), Shahriari Rad H(1), Bahramian F(1), Alidousti A(2), Aslani H(3). A treatment gap exists for patients with lesions not suitable for arthroplasty or biologic repair or … Microfracture treatment results in better outcomes in patients with BMI <30. Hip Dislocation: How Does Delay to Reduction Affect Avascular Necrosis Rate? Some features of the site may not work correctly. Before the development of modern bioengineering techniques, orthopedists were restricted to procedures that aimed to palliate the effects of chondral lesions or attempted to stimulate a healing response initiated from the subchondral bone resulting in the formation of fibrocartilage to fill the defect. 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. 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. Recent MR scanning techniques such as MR arthrography, magnetization transfer imaging, and fast spin echo sequences have improved the visualization of chondral defects. The field of cartilage repair is a recent development within orthopedic surgery with techniques that continue to evolve. Large osteochondral defects involving the femoral condyles of the knee have frustrated orthopaedic surgeons for generations. Even though the natural history is still not completely understood, those involved in cartilage repair agree that one must look for background factors that predispose to the formation of these defects—malalignment and compartment overload of the tibiofemoral or patellofemoral compartments, joint laxity, contracture, meniscal insufficiency, and of course, genetic predisposition to osteoarthritis—for which to date clinical, biological, or genetic markers are lacking. Brigido and Amber Shane, DPM, FACFAS, cite a study by Raikin concerning 15 patients with osteochondral lesions of the talus who had osteochondral autograft transplantation (OATS). Surgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants. A large knee osteochondral lesion treated using a combination of osteochondral autograft transfer and second-generation autologous chondrocyte implantation: A case report Regen Ther . Treatment of osteochondral injuries and osteochondritis dissecans (OCD) is … Is There a Role for Arthroscopy in the Treatment of Knee Osteoarthritis. 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. MINAS, MD, MS, ANDREAS H. GOMOLL, MD. 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. The tibia and fibula bones sit above and to the sides of the talus, forming the ankle joint. 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. Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm2), often with associated bone loss. ACI is indicated for the treatment of medium to large chondral defects with no or shallow associated osseous deficits. Kreuz and Erggelet10, Evidence-Based Orthopaedics The Best Answers to Clinical Questio. In conclusion, treatment of early knee osteoarthritis and chondral lesions is still a challenging problem. It serves as al low friction high wear resistance surface to ideal provide mobility and strength. Osteochondral cylinders are harvested from lesser marginal weight-bearing areas of the knee joint and press-fitted into the prepared defect. Surgical options range from simple fragment excision to internal fixation of the fracture fragment to more complex cartilage restoration or replacement procedures. TOM. Unlike hyaline cartilage, this fibrocartilage largely consists of type I collagen and is mechanically less stable and less durable.5 The pluripotential marrow-derived cells may also form bone, another mode of MST-related failure that is increasingly becoming recognized.6 Although closely related, MSTs vary by the degree of trauma to the subchondral bone, which has been recognized as a factor in the failure of these techniques. Treatment may include activity modification, drilling, fixation, or osteochondral replacement of osteochondritis dissecans lesions in the knee. Download : Download high-res image (1MB) A cartilage defect is an area of damaged cartilage. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. 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. What Is the Best Treatment for End-Stage Hallux Rigidus? Subchondroplasty, a procedure developed to treat bone marrow edema lesions by injecting a bone substitute, is one of the evolving treatment options for patients with SIF. When filling osteochondral defects in the knee, surgeons have a list of treatment options to choose from and more options are in the works. 2013;41(3):528-34. Osteochondral allograft transplantation uses cartilage from outside the patient, usually from a cadaver. The resultant blood clot, and the primitive mesenchymal cells contained within, may differentiate into a fibrocartilaginous repair tissue that fills the defect. The main concerns with allograft transplantation are failure to incorporate with subchondral collapse and the risk for disease transmission (estimated at 1 in 1.6 million for the transmission of HIV9). The high costs and extensive rehabilitation associated with many of these procedures necessitate careful evaluation to establish their respective clinical and cost-effectiveness. Treatment of type V osteochondral lesions of the talus with ipsilateral knee osteochondral autografts. 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. Treatment Options Articular cartilage has no blood supply and its ability to repair itself is poor. Microfracture treatment shows best results in femoral condyle lesions. 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. PRICE stands for: Protection – protect the affected area from further injury by using a support, such as a knee brace Success rates for nonoperative treatment with sports restriction and nonsteroidal anti-inflammatory drug or cast immobilization differ from 0% to 100% (review article 12). When Should a Unicompartmental Knee Arthroplasty Be Considered? This special focus section will discuss the diagnosis and treatment options for traumatic osteochondral knee injuries, including the subset secondary to juvenile OCD lesions. 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. TABLE 96-1 Overview of Cartilage Repair Studies, TABLE 96-2 Treatment Recommendations and Respective Level of Evidence. What are the options for treating a chondral defect of the knee caused by sports trauma? The causes of osteochondral injuries are not yet completely understood, but some theories are lack of blood supply to the affected area, heredity, direct compressive trauma or repetitive strain. Symptoms. Commonly, multiple cylinders have to be transplanted to fill larger defects. The main concerns with allograft transplantation are failure to incorporate with subchondral collapse and the risk for disease transmission (estimated at 1 in 1.6 million for the transmission of HIV, Treatment Recommendations and Respective Level of Evidence, Microfracture treatment shows better results in smaller defects. Surgical Treatment Options for Osteochondritis Dissecans of the Knee Cecilia Pascual Garrido, MD, Allison G. McNickle, MS, and Brian J. Cole, MD* Osteochondritis dissecans of the knee is identified with increasing frequency in the young adult patient. 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. 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. We can confirm the effect of mosaicplasty on the improvement of patients with osteochondral lesions of the ankle, suggesting it as a treatment option. This joint permits much of the up (dorsiflexion) and down (plantarflexion) motion of the foot and ankle. Table 96-1 provides an overview of cartilage repair studies. Unlike hyaline cartilage, this fibrocartilage largely consists of type I collagen and is mechanically less stable and less durable. This chapter provides an overview of the existing techniques and supporting data in an attempt to guide surgeons in their indications for the treatment of cartilage defects of the knee. Transchondral drilling for osteochondritis dissecans of the medial condyle of the knee, Osteochondral autograft transplantation for juvenile osteochondritis dissecans of the knee: a series of twelve cases, Juvenile Osteochondritis Dissecans of the Knee: Predictors of Lesion Stability, Extraarticular Drilling for Stable Osteochondritis Dissecans in the Skeletally Immature Knee. No single treatment works for everybody. Osteochondral defects are amenable to osteochondral allograft transplantation. TREATMENT OPTIONS. The use of a collagen membrane in place of a periosteal patch for ACI reduces the reoperation rate for graft hypertrophy. Pain with weight bearing activities Yoshimura I, Kanazawa K, Takeyama A, et al. Table 96-2 provides a summary of treatment recommendations and respective levels of evidence for chondral defects in the knee. This special focus section will discuss the diagnosis and treatment options for traumatic osteochondral knee injuries, including the subset secondary to juvenile OCD lesions. How to Treat an Osteochondral Lesion: Brace Even though wearing a cast or a brace might help to alleviate some of the pain caused from the lesion, they are often not enough to correct the problem on a permanent basis, except for children who tend to respond good a to non-surgical approach. An allograft is usually used when cartilage defect being treated is too large for an autograft (≥2cm). 1 Treatment options … Knee osteochondral fractures in skeletally immature patients: French multicenter study. ACI, autologous chondrocyte implantation; ACI-c collagen-covered autologous chondrocyte implantation; BMI, body mass index; MACI, membrane-associated autologous chondrocyte implantation. 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… 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. 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. What Are the Best Diagnostic Criteria for Lateral Epicondylitis? Scranton PE Jr, McDermott JE. Chapter 96 What Is the Best Treatment for Chondral Defects in the Knee? 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. Long implicated in the subsequent development of osteoarthritis, focal chondral defects result from various causative factors. Treatment of osteochondral injuries and osteochondritis dissecans (OCD) is … 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. A thorough history, physical exam, and imaging are essential to appropriately assign symptoms to the PF joint and cartilage pathology. 1 The knee joint is perhaps one of the busiest joints in the body as it bears most of the body weight when standing. Before the development of modern bioengineering techniques, orthopedists were restricted to procedures that aimed to palliate the effects of chondral lesions or attempted to stimulate a healing response initiated from the subchondral bone resulting in the formation of fibrocartilage to fill the defect. Left untreated, The talus is the bottom bone of the ankle joint. CONCLUSION: Osteochondral allograft transplantation is a useful salvage treatment option for reciprocal bipolar cartilage lesions of the knee. 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. High reoperation and failure rates were observed, but patients with surviving allografts showed significant clinical improvement. Furthermore, osteochondral allografting presents a viable salvage option after failure of other cartilage resurfacing procedures. 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. Within the knee, cartilage damage can happen between the thigh bone and the shinbone. 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. Treatment of osteochondritis dissecans is intended to restore the normal functioning of the affected joint and relieve pain, as well as reduce the risk of osteoarthritis. In children whose bones are still growing, the bone defect may heal with a period of rest and protection. Treatment strategies for osteochondral defects (OCDs) of the ankle have substantially increased over the last decade. Osteochondral cylinders are harvested from lesser marginal weight-bearing areas of the knee joint and press-fitted into the prepared defect. 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. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI.
