Effectiveness of Total Knee Replacement

Total knee replacement

Long considered as the “gold standard” surgery for knee arthritis, total knee replacement is still by far the most commonly performed joint replacement process. It is appropriate for middle-aged and older people who have arthritis in more than one compartment of the knee and who do not expect to return to high-impact athletics or heavy labor work. Results of this process are usually outstanding with 95% of total knee replacements continuing to function well for more than 10 years after operation.

Effectiveness of total knee replacement

Current research suggests that when total knee replacements are performed well in right selected patients, success is achieved in large majority of patients and the implant serves the patient well for several years. Many researches show that 90-95 percent of total knee replacements are still functioning very well even after 10 years of surgery. Most patients walk without the help of a cane, most of them can climb stairs, sit and get up easily from chairs, and most of them resume their desired level of recreational activity.

In many cases, the total knee replacement requires re-operation sometime in the future; it can always be revised (re-done) successfully. However, results of revised knee replacement are usually not as good as first-time knee replacements. There is good evidence that the experience of the knee surgeon correlates with outcome in total knee replacement surgery. It is best to have the initial surgery done by an experienced surgeon. Surgeons with several years of experience have been shown to have fewer complications and better results. It is therefore significant that the surgeon performing the technique just not be a good orthopedic surgeon, but a specialist in knee replacement surgery.

Precaution to be taken after knee replacement surgery

After operation, you’re wheeled to a recovery room for at least one to two hours. You’re then moved to your hospital room, where you usually stay for a couple of days. You might feel little pain, but medications prescribed by your surgeon should help to control it. During the hospital stay, you’re encouraged to move your ankle and foot, which will increase the blood flow to your leg muscles and will help to prevent swelling and blood clots. You might need blood thinners, support hose or even compression boots to further protect against swelling and clotting.

The day after operation, a physical therapist shows you how to exercise with your new knee. During the first few weeks after operation, a good recovery is more likely to take place if you follow all the orthopedic surgeon’s instructions which are concerned with wound care, diet and exercise. Your physical activity program will comprise of:

  • A graduated walking program: first indoors, then outdoors, will help to increase your mobility
  • You need to slowly resume to other household activities, which include: walking up and down stairs
  • Knee-strengthening exercises which are recommended by the hospital physical therapist, should be performed several times a day

Knee Pain Relief: an ACL Injury & the Role of Reconstructive Surgery

Tears or ruptures of the Anterior Cruciate Ligament (ACL) are common damages in athletes of different ages and activity levels.  ACL tears are treatable using arthroscopy and nominally invasive surgical methods. The medical success rates for ACL reconstruction exceed 95%. The anterior cruciate ligament is one of the main supportive ligaments in the knee. It runs from the lower leg bone (tibia) to the thigh bone (femur) at the knee. This ligament provides knee immovability by preventing extreme forward movement of the tibia in relation to the femur and is also significant in controlling rotation of the two bones.

While the ACL is not the most usually injured knee ligament, tears of this ligament normally lead to chronic knee instability or “giving way. Anterior cruciate ligament tears most commonly result during athletics from vital cutting, landing, deceleration or twisting damages. It is less common for ACL tears to happen as a result of physical contact or collisions during athletics.Many patients who undergo an ACL tear will know immediately that something “feels wrong” with the knee. Several patients report feeling or hearing a “pop” linked with pain and a sense of the knee “giving out”. The joint will usually swell within several hours which results in limited motion of the knee. It will become painful to bear weight on the damaged leg, and the patient will prefer to walk with assertive devices for added support, such as crutches or a cane. Sometimes, the patient may know-how the knee “giving way” when stressed with simple activities such as walking or changing directions.

What Causes an ACL Injury?

An ACL injury is generally sports-related knee damage. About 85% of sports-related ACL tears are “non-contact” damages. This means that the damage occurs without the contact of another player, such as a tackle in football. Most often ACL tears happen when pivoting or landing from a jump. Your knee gives-out from under you once you tear your ACL. Female athletes are known to have a higher risk of an ACL tear, while contributing in competitive sports. Unfortunately, understanding why women are more inclined to to ACL injury is uncertain. There are some suggestions it is bio mechanical, power and hormonal related. In truth, it is possibly a factor of all three.

What are the Symptoms of an ACL Injury?

The diagnosis of an ACL tear is made by numerous methods. Patients who have an ACL tear generally sustain a sports-related knee injury. They may have felt or heard a “pop” in their knee, and the knee generally gives-out from under them. ACL tears cause knee swelling and pain.

How is an ACL Injury Diagnosed?

On clinical knee checkup, your physiotherapist or sports surgeon will look for signs of ACL ligament instability. These special ACL tests places stress on the anterior cruciate ligament, and can notice an ACL tear or rupture.

How is an ACL Injury Treated?

Many patients with an ACL tear start to feel healthier within a few days or weeks of ACL injury. These individuals may feel as though their knee is normal again, as their swelling has started to settle. However, this is when your problems with knee instability and giving way may start or worsen.ACL tears do not essentially require ACL reconstruction operation. There are several significant factors to consider before deciding to undertake ACL reconstruction operation.

  1. Your age
  2. If you regularly perform sports or activities that normally require a functional ACL
  3. If you experience knee instability
  4. You need to plan for the future

If you don’t contribute in a multi-directional sport that requires a patent ACL, and you don’t have an unstable knee, then you may not need ACL operation.
