To date, some osteochondral biomimetic scaffolds have been tested in clinical practice. However, due to great diversity in the articles and variability in treatment results, no definitive conclusions can be drawn. Platelet-Rich Plasma and … Osteochondral lesions of the talus (OLTs) continue to be a challenge for the treating surgeon, especially when lesions are refractory to marrow stimulation techniques. Further sufficiently powered, randomized clinical trials with uniform methodology and validated outcome measures should be initiated to compare the outcome of surgical … Surgical options, such as microfractures, ACI and OAT, provide good, but not fully satisfying, outcomes. Als osteochondrale Transplantation (Knorpel-Knochen-Transplantation) wird in der Orthopädie und Unfallchirurgie die Verpflanzung (Transplantation) eines gesunden Gelenkflächenabschnittes in den Bereich eines Knorpel- oder Knorpel-Knochendefektes bezeichnet.Die Transplantation kann autolog, aus körpereigenem Material oder homolog (Fremdgewebe) erfolgen. Is Your Knee Pain Coming From a Meniscus Tear or Ligament Strain/Tear? The need for treatment of concomitant cartilage lesions during patella instability surgery will be discussed in a later section. The Lysholm knee score was 95. However, since they were just recently developed and used in clinical practice, we only have results at short-term evaluations. T These cartilaginous injuries often occur in athletes and may significantly limit elite performance if left unaddressed. When there is a break, tear, separation, or disruption of the cartilage that could be referred to as an osteochondral lesion. Concerning the new techniques of biomimetic osteochondral scaffolds and bone marrow-derived cell transplantation, they have provided results comparable to those of ACI and shown they are capable of overcoming some of the disadvantages of the older tissue regeneration techniques. A rticular cartilage lesions are still one of the most important problems in orthopaedic surgery, es- pecially in young and athletic people. Design: Osteochondral lesions (2.0 × 1.5 cm) were chiseled out on both condyles and trochlea in eight human cadaveric knees. Loose body is common: Talk to your dr. As loose body is very common. The management of osteochondritis dissecans (OCD) requires a careful evaluation. 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. ‹ Osteochondrosis dissecans (OD) im Sprunggelenk nach oben. Treatment of osteochondral lesions of the talus: a systematic review. scaffold onto the lesion site, which was They can start as bone bruising that develops into an osteochondral lesion. 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 . Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. In some rare cases, osteochondral lesions can occur for no apparent reason. Dr. Veena Govila answered.  Although majority may be associated with trauma, some may develop insidiously. Initial treatment and self care . MRI showed that the osteochondral lesion had been ﬁlled, but the restored medial meniscus displayed increased degenerative changes and abra-sion (Fig 5). Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. Knee Surg Sports Traumatol Arthrosc. PVNS is a rare condition affecting the joints and presence of a bone lesion in association with it is even rarer, especially in the knee joint. Multiple overlapping stamps or patches of the membrane can be positioned in the defect.  This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Osteochondritis dissecans is a painful joint problem. 1 (A–C) Intraoperative views of an articular cartilage lesion on the medial femoral condyle. MaioRegen is available in three different configurations: MaioRegen Prime for the treatment of osteochondral lesions with severely compromised subchondral bone MaioRegen Slim for the treatment of osteochondral lesions with slightly compromised subchondral bone MaioRegen Chondro+ for the treatment of cartilage lesions Furthermore, ischaemia, abnormal ossification patterns and endocrine abnormalities have all been implicated as the potential … Fig. Franz König coined the term osteochondritis dissecans in 1887, describing it as an inflammation of the bone–cartilage interface. Chondral lesions of the knee are common, with a prevalence of more than 60% in those undergoing knee arthroscopy. org/ 10. OCD Lesion – Knee Arthroscopy with Cartilage Repair and Regeneration - Duration: 5:06. [2,3] Unfortunately, the poor healing potential of hyaline cartilage limits injury management. The osteochondral autologous transplantation (OAT) procedure done for large OCD lesions involves a single surgery and takes advantage of implanting mature autologous bone … Osteochondral lesions are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. Osteochondral defects are most commonly found in the thighs, shins and knees – areas that bear a lot of weight. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management.. stage I. injury limited to articular cartilage; MRI findings: subchondral edema; x-ray findings: none; stage II. In case of wide lesion multiple plugs can be used to resurface the entire affected area, and in this case it is mandatory to proceed sequentially with … The ideal lesion candidate for this treatment is a chondral or osteochondral defect in an easily accessible surface of the knee .

The osteochondral autologous transplantation (OAT) procedure done for large OCD lesions involves a single surgery and takes advantage of implanting mature autologous bone and cartilage, which have excellent survival rates. A bone marrow-derived cell transplantation procedure starts with the aspiration of bone marrow from the patient’s iliac crest. Seventeen patients Knee Preservation and Cartilage Restoration Center, OrthoIndy, Indianapolis, Indiana. 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). Otherwise, for the majority of cases of PF chondral/osteochondral lesion(s) and/or underlying malalignment, failure of up to 6 months of conservative treatment is warranted. On the other hand, the amount of graft that a donor site can provide is limited and that also determines the so-called “donor site” morbidity, of which surgeons should be aware.
