The knee is the largest and one of the most complex joints in the body. It is also one of the most common joints to suffer injury and cause disability. Problems with the knee can be classified as 1) poor mechanics 2) trauma and overuse, and 3) arthritic changes. Problems 2 and 3 are closely linked with number 1. Nearly all knee problems revolve around mechanical issues which put abnormal amounts of stress to soft tissues (tendons, ligaments, and cartilage) of the knee. Common examples of abnormal mechanics include subluxation (knee, sacroiliac, lumbar spine, or foot), muscular imbalance (especially quadriceps which can cause patellar mistracking), muscular tightness, and foot problems (pronation, flat arches, high heels, etc.). Trauma to the knee many times initiates mechanical problems which, if left uncorrected, will lead to problems. Degenerative arthritis is a classic example. Years of poor biomechanics will cause knee cartilage to wear out and bones will begin to rub upon one another causing bone spurs, pain, and sometimes even knee surgery. Recently, arthroscopic knee surgery for osteoarthritis (performed 200,000 times per year) has been shown to be no more effective than sham surgery.
Chiropractic and Knee Pain
The Chiropractic doctor addresses aspects of the knee which are many times overlooked. Subluxations in the sacroiliac joints, lumbar spine (which affect spinal nerves to the knee) and foot must be addressed to ensure proper knee function. Chiropractic adds adjustments to the knee itself (if indicated) to help restore motion and release tissues that may be pinched or caught between the bones. Muscular imbalances are also important and are positively affected by removing subluxations. Studies have shown that muscular inhibition (a common cause of anterior knee pain) is improved by adjusting the sacroiliac joint. Many chiropractors are equipped to prescribe orthotics when indicated or can refer to an appropriate health care provider.
