INTRODUCTION. It usually occurs in the knee, ankle or elbow. During the second arthroscopic procedure, the surgeon implants the expanded cultured chondrocytes, which were seeded onto a hyaluronic acid (HA) membrane. Platelet-Rich Plasma and … Level of Evidence: Level IV, Case Series. Arthroscopy 2008; 24 (01) 62-68 Arthroscopy 2008; 24 (01) 62-68 54 Jehan S, Loeffler MD, Pervez H. Osteochondral fracture of the lateral femoral condyle involving the entire weight bearing articular surface fixed with biodegradable screws . Chondral lesions of the knee are common, with a prevalence of more than 60% in those undergoing knee arthroscopy. The bone right underneath the cartilage will also be injured. Knee microfracture surgery is effective in providing significant relief for the symptoms that are caused … MRI showed that the osteochondral lesion had been ﬁlled, but the restored medial meniscus displayed increased degenerative changes and abra-sion (Fig 5). A clinical assessment was performed using VAS score, Lysholm score, and Tegner activity level after an average follow-up of 27 months (SD: 2.3). However, deterioration of clinical outcomes and fibrocartilage infill over time is now a recognized concern. Knee microfracture surgery is a surgical procedure used in the treatment of areas with damaged cartilage. Overall, cartilage restoration techniques have yielded favorable clinical outcomes and can be successfully employed to treat these challenging large focal lesions.Thieme. Larger lesions with progressive articular collapse and persistent pain may require surgery (often total knee arthroplasty). Arthroscopic microfracture is considered the primary treatment strategy for osteochondral lesions of the talus and has been shown to provide successful outcomes. The structure of this scaffold helps confine bone formation to the deepest portion of the lesion and cartilage regeneration to the surface of the area without the need for introducing any cell or growth-factor supplements to the surgical site. When compared to ACI, this technique is less expensive and it has further advantages because it requires a single surgical time. osteochondral lesions knee. Level of Evidence: Level IV, Case Series. In the paste-graft approach surgical technique, cartilage harvested from the margin of the intercondylar notch and cancellous bone harvested from the proximal aspect of the tibia are morselized to obtain a paste. Recently, the amazing progress achieved in the field of biomaterials and tissue engineering led to the development of new therapeutic strategies aimed at tissue regeneration. Surgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants. [2,3] Unfortunately, the poor healing potential of hyaline cartilage limits injury management. [2,3] Unfortunately, the poor healing potential of hyaline cartilage limits injury management. osteochondral lesions of the knee and talus in the athlete. However, ACC.20/WCC Virtual Meeting continues to release cutting edge science and practice changing updates for cardiovascular professionals on demand and free through June 2020. Dr. Hany Elrashidy - Orthopedic Surgeon 31,310 views What is more, the entire pool of regenerative cells being used is concentrated directly in the operating room at the time of surgery, which eliminates the need for separate steps for cell selection and expansion. However, since they were just recently developed and used in clinical practice, we only have results at short-term evaluations. cartilage injury with associated subchondral fracture but without detachment Large osteochondral defects involving the femoral condyles of the knee have frustrated orthopaedic surgeons for generations.
