Update on Knee Osteonecrosis from the Johns Hopkins University

Sometimes orthopedic surgeons are faced with rare conditions they either haven't seen before or have only treated a handful of times. Osteonecrosis alink_delimiter_one_string of the knee is one of those problems. Osteonecrosis of the hip is a much more common problem. Developing diagnostic and treatment guidelines for rare conditions based on clinical experience isn't always possible. That's when physicians rely on articles like this one that provides a review of recently published literature.Osteonecrosis is the death of bone tissue. There are three types of knee osteonecrosis: 1) spontaneous (occurs without a known cause), 2) post-arthroscopy (occurs after an arthroscopic procedure), and 3) secondary to some other condition such as lupus, use of steroids, or alcohol abuse.

Osteonecrosis of the knee is rare after arthroscopy. It usually occurs when some form of heat such as laser or other thermal devices were used during the procedure. The patient starts to develop worse pain after arthroscopy than before. Knee swelling is a common feature of this problem.

Researchers consider the unilateral knee arthroplasty a very promising approach, but once again, more studies are needed to confirm these results and to see what happens in the long-run.Results reported from a limited number of studies report excellent results with this technique.
