Originating from the geniculate arteries, the meniscal arteries supply only the 25% of the cartilage matter of the peripheral meniscus, where the central area of the menisci receive nutrition from the surrounding synovial fluid. This means that in some anatomical locations, some tear will heal quickly even spontaneously, and in some types of tears, healing would need surgical interventions (Ballas & Stillman, 2009). Therefore, prior diagnosis of the location, disposition, depth, orientation, and extent of the meniscal tear becomes of utmost importance, since this would facilitate the optimum treatment and outcomes within the shortest possible time.
This specific dilemma has two parts, one questionable accuracy magnetic resonance imaging studies and failure of appropriate interpretation of the images to lead to a definitive diagnosis unequivocally (Luhmann, Schootman, Gordon, & Wright, 2005). On the other hand, delay for allowance of development of suggestive clinical signs or symptoms may lead to permanent damage. Before going into the details of these issues, it would thus be necessary to establish the facts that are known in each of these issues with an attempt to find relevance between these two, so the evidence base may be available for guiding practice. This issue has been dealt with in adequate detail in prior researches, and thus there is a need for extended literature review to glean what is known. Apart from establishing evidence from the known, it would also serve the purpose of identification of the gaps, so further research may be conducted on these suggestions.
Mesiha et al. (2006) indicated the tricky nature of human meniscal healing following injury. It has been observed that meniscus often fails to heal when the injury has caused a tear of more than 1 cm. similar phenomena have been observed when the tear involves the internal two-thirds of the meniscus (Mesiha, Zurakowski, Soriano, Nielson, Zarins, & Murray, 2006).
