The presence of an osteochondral lesion may initially go undetected and may manifest many months after the initial ankle injury. The advent of new procedures for repairing cartilage in knee and ankle joints has increased the need for accurate noninvasive methods to objectively evaluate the success of repair. [ 6] I In case of clinically suspected lesion with negative radiographs, advanced imaging options such as CT and MRI are useful. Pain under the metatarsal-phalangeal (MTP) joint is common in athletes and a tear or rupture to the plantar plate may be responsible for pain in this area. Foot Ankle Int.

Osteochondral injury and fractures are most commonly seen with first-time acute patellar dislocation sustained after a traumatic event that produces a large knee effusion. Medial OLT (superomedial) is more common than lateral OLT(3,6), however lateral OLT is more often associated with trauma compared with medial OLT (100% versus 64%)(7), and more likely in patients with chronic ankle instability(3).     - in adults, the tidemark zone is the weak link between the overlying cartilage and subchondral A Study of 5233 Knee Arthroscopies.

Impaired function, limited range of motion, stiffness, catching, locking and swelling may … J Bone Joint Surg Am. The repair of osteochondral defects using an exogenous fibrin clot. The cartilage on the talus has less inherent stiffness than the corresponding sites on the tibia (18-37% stiffer on the tibia); therefore it is more vulnerable to harm from shear and compression than the tibia(4).

StageFeatures/definition The combined use of standard and newer magnetic resonance (MR) imaging techniques makes it possible to evaluate both the morphologic status and the biochemical contents of the repair tissue (,1–,9). An ankle sprain due to rotational forces likely causes OLT injuries. PubMed CrossRef Google …     - debridement of chondral defects and microfracture  Typically, there is a compressive component to the movement that causes the ankle injury (such as inverting when landing from a jump) in association with a shear-type force, as the talus moves across the tibial plafond or the fibula.
