ICD-10 code S83. 231A for Complex tear of medial meniscus, current injury, right knee, initial encounter is a medical classification as listed by WHO under the range - Injury, poisoning and certain other consequences of external causes .
Description of Posterior Horn Medial Meniscus Tear The posterior horn of the medial meniscus is that portion of the medial meniscus in the back part of the knee. It varies from the main weightbearing portion of the meniscus up to where it attaches on the tibia at its lateral aspect, called the root attachment.
The medial meniscus posterior root tear (MMPRT) leads to loss of hoop tension and, thus, loss of load transmissibility of the meniscus, which results in a biomechanical condition much like total meniscectomy5).
Description of Posterior Horn Lateral Meniscus Tear Thus, the loss of the lateral meniscus can often lead to rather rapid onset of osteoarthritis. Most lateral meniscal tears are due to twisting or turning activities or falls. Lateral meniscal tears are common in sports such as skiing.
A complex lateral meniscus tear can include a radial tear, a radial flap tear, a tear that is chewed up and macerated, or a root tear. In general, a simpler type tear would be one that is very small and trimmable or one that is torn at the meniscus attachment to the joint lining, which is easily repairable.
The posterior horn of the meniscus refers to the one-third of the meniscus that is in the posterior (back) of the knee. The posterior portion of the medial meniscus is also the thickest portion and is known to absorb the most force.
A complex meniscal tear is most often experienced in younger people due to a sports related traumatic event. The forces on the knee can become so great that the meniscus is squished and pulled at the same time. Large, diverse stresses at different stress points can tear the meniscus into more than one tear shape.
Treatment of a Posterior Horn Medial Meniscus Root Tear Surgery is often required to repair a posterior horn medial meniscus root tear and slow down any progression of osteoarthritis. The two most common surgical procedures are suture anchor repair and transtibial pullout repair.
