Knee Pain Seminar

Chichi_knee anatomy
For millions of Americans, knee pain is a daily reality. Many people try to ignore pain caused by arthritis in the knee joint for as long as possible in hopes that it will go away. However, arthritis is a progressive disease and for many, will even become debilitating. On December 3, 2013, orthopedic surgeon Dr. Demetris Delos presented a “Knee Pain Seminar” addressing treatment options for knee pain due to early-stage arthritis. He discussed non-operative and operative solutions from therapeutic injections, arthroscopic procedures to osteotomy and partial knee replacement. The seminar was free and open to the public.

Cartilage Transplantation Offers New Hope for Damaged Knees

Dr. Demetris Delos

Cartilage transplantation offers exciting new treatment options for adults under the age of 50 who have had their knee damaged through acute or chronic trauma to the knee. The surgeon uses small cylindrical plugs of good cartilage and inserts them into the damaged areas. This procedure has been shown to be highly effective in patients who have sustained a specific injury to the knee cartilage or joint lining, and who have not yet developed arthritis. Many competitive athletes who have undergone the treatment have returned to their full performance level after surgery.

Who would know better how to treat active women of all ages and levels of sports activity than the ONS Women’s Sports Medicine Center physician and physical therapy team?

In addition to being experts in their fields as orthopedic surgeons and sports medicine specialists, the ONS Women’s Sports Medicine Center team is comprised of current and former athletes and fitness enthusiasts who know first-hand what it takes to train and excel in a sport. (In fact, Dr. Katie Vadasdi, an orthopedic surgeon, is an accomplished tri-athlete who has completed two Ironman competitions, is an alpine climber and has ascended Mount Kilimanjaro, Mount Rainier and the Grand Teton.)

Come hear the ONS Women’s Sports Medicine Center panel discussion hosted by Greenwich Hospital:

“Women Treating Women”

The event, which took place in the Noble Conference Room at Greenwich Hospital, featured the ONS Women’s Sports Medicine experts in a panel discussion regarding the latest diagnostic and medical management techniques for injuries and conditions common in female athletes.

The public was invited to bring their sports injury or fitness-related questions and get answers from a team of physicians who have provided medical support to five Olympic Games, international biking and fencing championships, and medical coverage for the Columbia University sports teams and Greenwich High School sports.
