But according to a 1990 study, 56% of bipolar patients also have a substance abuse problem, which can make treatment even more difficult. Experts say that some bipolar patients are known to self-medicate with drugs or alcoholthough it's not recommended. In fact, they say, it does more harm than good.
A Meniscus Tear. The two most common causes of a meniscus tear are due to traumatic injury (often seen in athletes) and degenerative processes (seen in older patients who have more brittle cartilage). It is not uncommon for the meniscus tear to occur along with other damage inside the knee.
Overview, Causes, & Risk Factors. The meniscus is cartilage inside the knee joint. Tearing can occur on either side, the medial (inside) or lateral (outside). Meniscus is the name for either of two pieces of tough cartilage inside the knee joint.They are shaped like half moons and are sometimes called semilunar cartilage.ost tears do not heal, and become larger, because the inner two-thirds of the meniscus has no blood supply for healing. If the usual meniscus tear is not treated, problems in the knee will increase with time. The ultimate trouble can be the development of arthritis.
