- Pain in the knee(s)
- Knee joints may be warm and tender to the touch
- Boney deformities may been seen or felt around the knees
What is Arthritis?
Arthritis is loss of cartilage (cushioning material) between the bones resulting in bone-on-bone contact. Loss of this cartilage results in pain and limited range of motion sometimes occurs. The type of arthritis that commonly occurs in the knees is called osteoarthritis. Osteoarthritis is a degenerative joint disease that may be hereditary or maybe the result of overuse (wear and tear), excess weight, developmental disorders and/or injury. Joint space narrowing as result of cartilage loss, often causes bone spurs to develop and can severely alter joint biomechanics. In severe cases, the joint may become unstable. Occasionally these alterations of normal knee function may lead to visible “bowleg” or “knock-knee” joint deformities. Osteoarthritis can be extremely painful and can cause aching, swelling, and stiff joints.
Implementing lifestyle modifications such as losing weight, switching from high impact exercise (i.e. running) to low-impact exercise (i.e. swimming or biking), and avoiding aggravating activities can be very effective for reducing pain associate with knee arthritis. Even a modest weight loss of only a few pounds can significantly effect the amount of joint pain you’re experiencing. Supplementing with glucosamine, chondroitin or other natural anti-inflammatories may be helpful. Other non-surgical treatments to help relieve pain and discomfort associated with mild cases of arthritis include taking anti-inflammatories, wearing a knee brace or sleeve, using a cane, wearing energy absorbing shoes or inserts, and/or receiving corticosteroid injection(s). While non-surgical treatment can relieve mild cases of the condition, surgery may be necessary if it continues to worsen.
Diagnosis Using Knee Arthroscopy
When your knee becomes painful from overuse or arthritis, your surgeon may recommend knee arthroscopy (looking at your joint using a tiny video camera) to diagnose and even treat your problem. When you undergo the arthroscopic procedure, your surgeon can better understand the extent of your condition and may find less invasive options that can eliminate your symptoms.
Arthroscopic Knee Surgery (Minimally Invasive)
Dr. John Hoffman and Dr. Tuvi Mendel, our experienced orthopaedic surgeons, perform arthroscopic knee surgery as a minimally invasive method of relieving pain and restoring function. During surgery, small incisions are made through which an arthroscope (small video camera) is inserted into your knee joint to allow your surgeon to view the surgery on a monitor. Less severe cases of knee osteoarthritis respond well to surgical debridement, which means to “clean-up the joint.” Special equipment is used to remove bone spurs and damaged tissue to improve the healing potential of the healthy tissue. This technique results in smaller incisions, less scarring, less pain, and faster recovery than for open surgical procedures.
In cases of knee osteoarthritis in which the bony changes have altered alignment of the knee joint, your surgeon may perform an osteotomy (bone removal) of the tibia (shinbone), the femur (thighbone), or both. This procedure results in pain relief, proper realignment of the knee joint, and improved function.
Unicompartmental (Partial) Knee Replacement (Minimally Invasive, Outpatient Surgery)
In some cases of knee osteoarthritis, only a portion of the knee is affected. To spare the healthy, normal functioning portion of the knee, technologically advanced surgical techniques used by our fellowship-trained specialists allow our surgeons to replace only the damaged portion of the knee. With this minimally invasive procedure, only the severely damaged cartilage and bone is replaced, not the whole knee. This surgery requires only a small (approximately 3 inch) incision. This procedure generally results in more rapid pain relief, proper realignment of the knee joint, and improved function.
