Meniscus Tears and Knee Arthroscopy

One of the many causes of knee pain is a tear of the meniscus. Meniscus tears can cause an ache in the knee, worse with twisting, changing directions or squatting deeply.

PRP and Hyaluronic Acid

Platelet Rich Plasma injections (PRP) can help with the pain associated with knee arthritis as well as tendonitis in many areas.  Hyaluronic Acid injections can also help lubricate joints and decrease pain.

Partial Knee Replacement

Partial Knee Arthroplasty is a type of knee replacement involving only the diseased half of the joint. This is a less invasive procedure that allows for a more “natural” feel after surgery. A subset of Total Knee Replacement patients are candidates for this procedure.
