Knee osteoarthritis remains a significant problem among US adults 60 years and older. A recent study suggests knee arthritis rates as high as 37 % with women showing higher rates vs men (42% vs 31%) and higher rates among those with significant weight problems.
As a result, many of these patients opt for a total knee replacement. However, patients often suffer from pain and have difficulty walking for many years before deciding to proceed with such surgery. Living with pain for an extended period of time typically causes changes in how a patient walks in an attempt to relieve the pain associated with knee arthritis. Sometimes this is even done subconsciously, but it can lead to additional problems, such as low back pain (LBP). An example of this would be a knee flexed position that leads to leaning forward when walking. This changes at the pelvis which all contribute to low back pain.
