| 要約: | Osteochondral defects (OCD) are a focal pathology affecting the sub-chondral bone and overlying cartilage. The presence of Osteochondral defects (OCD) within the foot and ankle are well established. Despite this, they are often regarded as an insidious finding, prone to misdiagnosis which can result in significant debilitation to the affected individual. The mechanisms underlying the formation of these lesions remain disputed. Moreover, the incidence of isolated Osteochondral defects affecting the first Metatarsophalangeal joint in the absence of any additional pathology is unknown.There are a range of surgical treatment modalities described to treat Osteochondral defects. Strategies typically involve cartilage regeneration or replacement of the articular surface: however there are no consensus guidelines regarding the optimum surgical management when applied to the first Metatarsophalangeal joint. The following concepts review aims to explore the literature pertaining to the surgical management of Osteochondral defects including an innovative approach case study employing subchondral drilling technique.Osteochondral defects are managed with a variety of surgical procedures. Surgical outcomes are often derived from literature relating to the knee and hindfoot with little or no study on the forefoot. The included case study demonstrates positive patient satisfaction (PSQ-10) score, improved foot function (MOXFQ) and pain reduction with a novel antegraded Osteochondral drilling technique when applied to the first metatarsal. Further study into the application of contemporary cartilage regeneration and replacement strategies in this location is warranted.
