Partial Knee Replacement

If you are struggling with knee pain then you may be a candidate for partial knee replacement surgery. This is commonly the case when a patient’s knee pain is isolated to the inside of the knee, a condition called medial compartment arthritis.  About 8% of patients will have pain that occurs only underneath the kneecap indicating a condition called patellofemoral arthritis.  Both of these may be treated with partial knee replacement surgeries.Explore the links below to learn more about these procedures.  The best way to determine whether or not you are a candidate for partial knee replacement by meeting with a physician.

As the population in the United States ages and the average life expectancy increases, a growing number of patients will be affected by osteoporosis. Osteoporosis is weakening of the bone that occurs with age due to loss of the calcium structure. This is more prominent in women and particularly in postmenopausal women. Additionally another group of at risk patients are those who have had breast cancer and are treated with drugs called aromatase inhibitors which lower estrogen. 

Dr. Knauer is a member of the National Osteoporosis Foundation and is passionate about counseling and offering treatment options to people with this issue. If left untreated, osteoporosis can lead to chronic back pain and deformity as well as increase risk of hip fracture. .
