Cutting-edge surgery and surgery alternatives

20 years of experience and an emphasis on prevention

Dr. William F. Sima is committed to excellence by pledging to provide the highest quality of orthopaedic care possible. Along with the treatment of immediate or chronic problems, we strive to integrate the doctrine of prevention in all our treatment plans as a way to alleviate possible future difficulties.


Your joints are involved in almost every activity you do. Simple movements such as walking, bending, and turning require the use of your hip and knee joints. Normally, all parts of these joints work together and the joint moves easily and without pain. But when the joint becomes diseased or injured, the resulting pain can severely limit your ability to move and work.

Whether you are considering a total joint replacement, or are just beginning to explore available treatments, this website is for you. It will help you understand the causes of joint pain and treatment options. Most importantly, it will give you hope that you will be able to do more of the things you enjoy — with far less pain.

Enhanced Recovery After Surgery

Dr. Sima has been offering Enhanced Recovery After Surgery (ERAS®) protocols since 2015. ERAS refers to patient-centered, evidence-based, multidisciplinary team developed pathways for a surgical specialty and facility culture to reduce the patient’s surgical stress response, optimize their physiologic function, and facilitate recovery.
