Northridge Hospital Medical Center is proud to announce our designation as a Blue Distinction Center for Knee and Hip Replacement® by Blue Cross and Blue Shield of California. Blue Distinction Centers have a proven track-record for delivering better results – including fewer complications and readmissions – than hospitals without these recognitions.
The knee is the largest joint in your body and one of the most easily injured. Knee pain is very common and there are many causes. Knee pain may be due to problems with the bone or injury to muscles, tendons or bursae (small fluid-filled sacs that cushion and lubricate joints).
Northridge Hospital treats all knee problems. The most common are:
- Bursitis - inflammation of the bursa (small fluid-filled sacs that cushion and lubricate joints)
- Cartilage Injuries
- Knee Dislocation or Fracture
- Ligament Injuries
- Tendonitis - inflammation of the tendons may result from overuse of a tendon during certain activities such as running, jumping, or cycling.
Knee Care Examination and Treatment
A complete examination including X-rays, CT and/or MRI will be done to confirm a diagnosis. Treatment will then be determined by you and your physician taking into account your activity level, age, overall health, medical history and the extent of your condition. The goal of treatment is to provide relief from pain either through physical therapy, joint replacement surgery or medication.
What is arthroscopy?
An arthroscope is a small tube that is inserted into the body. It consists of a system of lenses, a small video camera and a light for viewing. It was originally used as a diagnostic only tool. Now with the advent of conjunction instruments for grasping, cutting and probing, the arthroscope can be used to perform minimally-invasive diagnostic and treatment procedures.
Conditions most frequently discovered during an arthroscopic procedure:
- Inflammation (including in the lining of the synovium in the knee, shoulder, elbow, wrist or ankle)
- Injuries, including the following:
- rotator cuff tendon tears, impingement syndrome and recurrent dislocations in the shoulder
- meniscal (cartilage) tears, chondromalacia (wearing or injury of cartilage cushion) and anterior cruciate ligament tears with instability in the knee
- carpal tunnel syndrome in the wrist
- Pieces of loose bone and/or cartilage (particularly in the knee, shoulder, elbow, ankle or wrist)
CPU-navigated Knee Procedure
Everyone is different and so are their knees! The precision of the CPU-navigated knee procedure helps to ensure the new joint has the stability and range-of-motion needed for a successful knee replacement. The "mini CPS system" takes into account each patient’s shape and size.
Computer navigated surgery maps the position of the bones which make up each patient’s knee joint using sensors which are placed at either side of the knee. These create a detailed image and provide real-time information on a computer screen which helps the surgeon accurately guide the implant into position.
During surgery, sensors create a detailed image of the bones that make up each patient’s knee joint. The precise measurement allows each replacement to be as accurate as possible. Plus, there is minimal disruption to the muscles around the affected area, resulting in faster recoveries.
- May increase the life of the knee replacement
- Reduces the risk of dislocation and revision surgery
- Results in greater stability and range-of-motion
- Faster recovery
- Reduced length of hospital stay
- Shorter post-operative physical rehabilitation
- Less scarring
Whether you have just begun exploring treatment options or have already decided to have total knee replacement surgery you can rest assured that Northridge Hospital has the physician expertise, modern surgical techniques and advanced post-surgery care. The expert orthopedic surgeons at Northridge Hospital perform nearly 5,000 procedures each year with over 1,000 specifically on hips and knees.
If knee pain limits your ability to walk, work or perform simple activities, you may want to talk to your doctor about a knee replacement. Joint replacement, a surgical procedure to remove and replace an arthritic or damaged joint with an artificial joint (called a prosthesis), may be considered only after other treatment options have failed to provide adequate relief from pain and/or disability.
Are You a Candidate for Knee Replacement Surgery?
You shouldn't consider this surgery as your first treatment option however, if you are a candidate for joint replacement, the results will likely please you. More than 90 percent of individuals who undergo total knee replacement experience a dramatic reduction of knee pain and a significant improvement in the ability to perform common activities of daily living.
For a patient to be considered for knee replacement surgery, an orthopedic surgeon must see evidence on an X-ray of significant damage to the articular cartilage. Major indications for knee replacement surgery include:
- Severe knee pain that limits your everyday activities, including walking, climbing stairs, and getting in and out of chairs. You may find it hard to walk more than a few blocks without significant pain and you may need to use a cane or walker
- Moderate or severe knee pain while resting, either day or night
- Chronic knee inflammation and swelling that does not improve with rest or medications
- Knee deformity: a bowing in or out of your knee
- Knee stiffness: inability to bend and straighten your knee
- Failure to obtain pain relief from nonsteroidal anti-inflammatory drugs. These medications, including aspirin and ibuprofen, often are most effective in the early stages of arthritis. Their effectiveness in controlling knee pain varies greatly from person to person. These drugs may become less effective for patients with severe arthritis.
- Inability to tolerate or complications from pain medications
- Failure to substantially improve with other treatments such as cortisone injections, physical therapy or other surgeries
What is Knee Replacement Surgery?
Knee replacement surgery removes the damaged joint lining and replaces the joint surfaces with a metal and plastic implant that functions similar to a normal knee. Since these implants will wear out over time, knee replacements are performed infrequently in younger patients.
When a knee replacement is performed, the bone and cartilage on the end of the thigh bone (femur) and top of the shin bone (tibia) are removed using precise instruments to create surfaces that can accommodate the implant perfectly. A metal and plastic knee replacement implant is then inserted to function as a new knee joint. The kneecap surface may also be replaced, if the cartilage underneath is in poor condition.
