Minimally Invasive Total Knee Replacement

Minimally Invasive (MIS) knee replacement is a new technique which can
significantly improve a patient’s rate of recovery from surgery. Dr. Stephen Kelly has been a leader in this field for OA Centers for Orthopaedics. He has successfully performed this procedure more than 500 times with significant improvements in patient’s pain after surgery and very rapid return to function.

Knee replacement surgery traditionally has required a 10-12 inch incision with the cutting of muscle and tendon. This new minimally invasive technique involves …

Graft Properties Affect Knee Ligament Surgery Outcome More Than Surgical Technique


In anterior cruciate ligament (ACL) reconstruction, graft stiffness and pre-strain play a more vital role than the choice of surgical technique, indicates a new study from the University of Eastern Finland. The study developed a computational 3D model of the knee joint, which can be used in the prevention of osteoarthritis (OA), specifically OA resulting from trauma.

OA is a major burden to society. It is estimated that over 100 million people suffer from …

Bad Knees: The Best Exercises to Prevent Further Injury

When people have bad knees, whether they were athletes for several years, received a detrimental injury or have osteoarthritis, it can be a pain – literally. Aside from limiting your daily activity, it can also make staying in shape a lot harder. Consider these exercises to keep active with bad knees.

Common mistakes

best exercises to prevent further injuryWhen people with bad knees exercise, they often make a few mistakes along the way. First off, many people try several different cardio exercises, which is not always a good idea. Only certain knee exercises can help burn calories without putting people in pain. When some do knee exercises, they may bend their knees past the front of their toes. This can aggravate knee joints and make orthopedic problems worse. This is because it puts intense pressure beneath the kneecap, stressing the muscles around it. People sometimes start to perform exercises that their knees cannot handle because they did not ask their doctor first, putting them in danger. Knowing knee strength and capability is crucial before starting any kind of exercise regimen.

Beneficial Knee Exercises

Think about trying out these activities at the gym to get a workout in. Complete these exercises in 10 or more repetitions.

Partial Squats – Many people know that regular squats can put bad knees in a lot of pain. However, partial squats can burn calories without aggravating the knee muscles. People begin this exercise similar to regular squats, with their feet hip-width apart. Slowly lower the body, making sure that the toes do not go past the knees. People should only go as low as is comfortable.

Step-Ups – Step-ups can help work the hamstrings, quads and gluteus muscles and strengthen knee muscles if done correctly. People can use an anaerobic step or a step on a staircase for this activity. Step up on one foot, tapping the other at the edge of the stair. Step down and switch. As with partial squats, the knee should not bend over the toes.

Calf Raises – This exercise strengthens the foot, ankle and calf muscles. Stand up with both feet pointed forward. Raise the heels off the ground slowly and then lower them again, making sure to keep the heels in sync. Going slowly makes the workout harder. If people have difficulty staying balanced, they can use a wall or chair for stability.

Hamstring Stretch – This activity helps promote circulation and prevents muscle injuries. People should begin by lying on their back with one leg straight out. Keeping the other leg straight, they should wrap a towel around the foot and pull the leg toward them, making sure that the knee does not lock.

Early Signs of Osteoarthritis (OA) in the Knee

Osteoarthritis (OA) is a common problem for many people after middle age. OA is sometimes referred to as degenerative, or wear and tear, arthritis. OA commonly affects the knee joint. In fact, knee OA is the most common cause of disability in the United States. In the past, people were led to believe that nothing could be done for their problem. Now doctors have many ways to treat knee OA so patients have less pain, better movement, and enhanced quality of life.

Signs of osteoarthritis

According to a HealthDayNews report, “Having knee pain while using the stairs may be an early sign of arthritis.” A study conducted at the University of Leeds included more than 4,600 people who were at high risk for arthritis. Researchers followed the volunteers for up to seven years.

Professor Philip Conaghan, a professor of musculoskeletal medicine at the University of Leeds in England stated in a news release, “At present, we have little concept of ‘early’ osteoarthritis and often only see people when they have significant, longstanding pain and loss of function.” He goes on to say, “This research is vital to understanding early symptoms of knee osteoarthritis.”

Using stairs was the first weight-bearing activity in which people with early knee arthritis noticed pain. They later developed pain while walking, standing, lying or sitting, and finally, while resting in bed.

“Knowing this will help us intervene earlier, perhaps leading to more effective ways of treating this very painful condition,” Conaghan explained.

According to Dr. Stickney, “Knee replacement is a very effective surgery for correcting deformity and relieving pain from arthritis. The typical conditions leading up to the need for a knee replacement are osteoarthritis, inflammatory arthritis like rheumatoid disease, and posttraumatic arthritis or damage to the cartilage after a prior injury. Knee replacement involves replacing or capping the joint surfaces where the cartilage has been damaged with metal and plastic components. The amount of bone removed in a knee replacement procedure is typically less than 9-mm. Typically, three of the four major ligaments of the knee can remain in place.”

Dr. Stickney goes on to say, “You should expect improvement after a knee replacement for 6 to 12 months. The majority of improvement will occur in the first two months. Most people require therapy for 2 to 3 months after surgery and most people will not return to work for 2 to 3 months after surgery. Typically physical therapy is performed in the home for the first two weeks after surgery and then on an outpatient basis for at least 2 to 3 months after surgery. The hospital stay after knee replacement is typically two days.”

Knee Problems Associated with Snowshoeing

knee problems associated with snowshoeingEnjoying the beauty of the Pacific Northwest on snowshoes is a great way to see the “country” on a beautiful winter day. Snowshoeing was invented sometime between 6,000 – 8,000 years ago; a method of travel for prehistoric people in snow conditions. As you’re climbing a low hill, your moving foot catches the tail of your snowshoe that’s planted and down you go. You feel a tearing pain in your knee. Lying on the ground, you feel your knee swelling like a balloon, and then the agony really starts.

Knee injuries are not uncommon among those who snowshoe.

Falling to one side or sliding downhill while wearing snowshoes can lead to a knee injury because of the torsional forces applied to the joint. Trying to move backwards while wearing snowshoes isn’t really a good idea either; the tail can get caught in the snow and hopefully the only indignity you’ll suffer is landing on your butt. And stepping on the tail of the planted foot with the shoe on the moving foot can result in you landing with your face in the snow and your knee moving in ways that were not intended.

Knee injuries fall into three broad categories: sprains, strains and kneemeniscal tears. Sprains are injuries to ligaments (which attach bone to bone) while strains are injuries to tendons (which attach muscle to bone). You have two menisci in each knee.

The knee consists of four bones: the two lower leg bones (the tibia and the fibula) the upper leg bone (called the femur) and the kneecap (patella). The knee is stabilized by ligaments; the ligament on the inner side of the knee is called the medial collateral ligament (MCL) while the outer is called the lateral collateral ligament (LCL). These ligaments provide left and right stability. You also have two ligaments inside of your knee – the anterior and posterior cruciate ligaments, abbreviated ACL and PCL, which cross from front to rear in an x-fashion. These ligaments provide forward and backward stability.

To complicate things even more, the knee contains cartilage (the same stuff your ears are made of). There are two pieces of cartilage in each knee; each piece is called a meniscus. The cartilage provides a cushion that prevents the tibia from banging into the femur. There is also cartilage lining the back of the patella.

Mechanism of Injury

When one falls while snowshoeing, the knee undergoes a tremendous torsional (twisting) force because the body moves while the foot is planted in one spot. When this occurs, any or all of the following can occur:

  • Sprains, which are tears in ligaments are injuries graded from I to III

o   Grade I: A mild stretching of the ligament with overly stretch fibers

o   Grade II: A partial tear in a ligament

o   Grade III: A complete rupture of the ligament

  • Meniscal tears, which can range from mild to severe
  • Fractures

The first thing to do after a fall is to lie there for a minute and assess your situation. After making sure the rest of your joints are operating properly, focus on the injured knee. A Grade I ligament tear will be painful, but you shouldn’t have much swelling. A Grade II tear is going to result in some swelling and throbbing, while a Grade III tear is going to involve a significant amount of swelling and pain. Since you’ve got two knees, it’s a good idea to compare your injured knee with the uninjured knee. In general, if the two knees look the same and you can move the injured knee without too much pain, you may be able to stand and walk a short distance. As with any injury, it’s best if you flag someone down and have them report your injury to authorities who are trained to manage these types of injuries (another reason to always take a snowshoeing buddy with you).

If you’ve fractured a bone in your knee or leg, you’ll definitely know it; the pain and swelling will preclude walking. If you’ve sustained a fracture, you will need the assistance of trained medical personnel to stabilize your leg and evacuate you so you’ll get proper medical care.

A tear of a meniscus can range from being barely noticeable to incapacitating. If your knee doesn’t hurt too badly, but seems “locked” (meaning that you can’t bend it), you may have possibly torn a meniscus and a piece of it is stuck and is interfering with your knee movement.

Like a meniscal tear, damage to the ACL or PCL can range from minor to severe. If either the ACL or PCL is totally ruptured, you will probably need surgery to repair the damage.

Sometimes a fall can result in a dislocated patella. The patella is the anchoring point for your quadriceps, so if your patella doesn’t “track” or slide well in its grove, the mechanical stability of your whole leg can be compromised. Generally, physical therapy can resolve the problem of a patella that isn’t tracking correctly.

If you sustain a knee injury while snowshoeing, avoid walking if at all possible. If medical help isn’t going to be available, splint your knee with tree branches, rolled newspapers or whatever you’ve got. NEVER try to straighten an injured, bent knee because you can turn a minor problem into something catastrophic. Do not move your knee; if you have a torn meniscus or even a tiny chip fracture and you move your knee, it can create havoc with the inside mechanics of your knee.

How can one prevent knee injuries? The best thing you can do is strengthening your legs by using by exercise. This not only keeps the leg muscles strong and toned, but also keeps your ligaments supple which can minimize the chance of injury. Keep in mind that as you age, your ligaments become less limber, so exercise becomes even more important as you get older.

Keeping in shape, using the proper equipment and keeping common sense foremost can result in the minimization of injury and the maximization of some healthy fun.

Exercises to Strengthen Your Knee


1. High step-up: Place one foot on the floor and the other on a bench about 16” high. Lift yourself to full standing; then lower yourself to the floor. Repeat 15 times, and repeat with the other leg.

2. Lunges: Step out with one leg and bend the other to 900. Step out with the bent leg and bend the other. Walk 15 steps with each leg.

3. Spinal Twist: Place your feet in a comfortable stance. Hold your arms out parallel to the floor and swing one arm forward and the other to the rear. Hold for one minute and repeat with the other arm. Repeat three times.

4. Wall Sits: Place your back against the wall. Slide down until your knees are bent 900 and hold for one minute. Repeat five times.

Knee Pain? Learn about Knee Tendinitis

Consider this statement, “Many people who participate in sports or fitness activities will get tendinitis at one time or another.” If you’re an avid athlete or fitness enthusiast like myself, chances are you have felt the discomfort of pain in your knees.

What is tendinitis?

Tendinitis is a persistent inflammation in the tendons. Typically in the knee, this involves the patella tendon between the kneecap and the tibia bone or the quadriceps tendon between the quadriceps muscle and the kneecap. The illiotibial band and the hamstring tendons can develop tendonitis as well. Injuries that do not adequately heal result in persistent inflammation and scar formation.

knee_dr stickneyOveruse is a common risk factor for tendinitis. When the tendon is stretched repeatedly by doing the same kind of exercise over a long period of time, the tendon can become strained and inflamed. Runners often get tendinitis for this reason. Tendinitis can also be caused by intense exercise over a short period of time.  For example, exercising all weekend to make up for the lack of physical exercise during the week. As we age our tendons become more brittle which makes our knees more vulnerable to stress and strain.

Tendinitis is usually treated with therapy, anti-inflammatory medications, and activity modification that allows for healing. Here are some tips to treating knee tendinitis:

  • Rest – Refrain from the activity that caused the tendinitis.
  • Ice – Apply ice wrapped in a towel for 15 minutes once or twice a day. Ice helps reduce swelling, which will lessen knee pain and speed healing of the tendon.
  • Elevate – Lie down and place your knee on a pillow so that it’s higher than your heart. This will aid blood flow and help reduce swelling.
  • Compress – Wrapping the knee in an elastic knee bandage can help reduce swelling and ease knee pain.
  • Ease back into activity – After your tendinitis disappears, don’t immediately go back to the same level of activity that caused your knee pain. Overdoing it can cause a recurrence of tendinitis. Warm up and stretch before beginning exercise. Then go slowly for a few weeks.
