Knee Replacement Surgery – Things You Need To Know

Knee replacement surgery is an important decision in a patient’s life suffering from related health issues. Let us have a look at some of the facts related to knee.

Minimally Invasive Surgery

There are two ways of conducting knee replacement surgery. The orthopedic surgeon can use the minimally invasive surgery or traditional surgery to replace the knee joint.

However, an overwhelming number of orthopedic surgery doctors give preference to minimally invasive surgery. The primary reason for this preference is use of smaller incision. The use of smaller incisions helps reduce the damage done to soft tissues.

Your orthopedic surgeon is the best person to decide the procedure for you. Some research studies show that minimally invasive surgery is better. In many cases it helps reduce hospital stays, reduce blood loss, and improves knee mobility function. However, some other studies suggest that at times it increases risk of complication. The poor position of knee implants can result in loss of motion.

Therefore, at times, minimally invasive knee surgery may not be the best option. The orthopedic surgery doctor will require bigger incision to have more working space.

Weight Loss Can Play Important Role

At times, simple lifestyle altering choices can go a long way in overcoming knee pain. For example, many orthopedic doctors maintain that we must maintain a healthy lifestyle. Similarly, they argue that we must keep body weight in check.

Overweight patients have more knee related problems to deal with. These patients can try reducing their weight to have an overwhelming impact. A loss of exercise in obese people results in loss of muscle.

The muscle around the knee also reduces due to no exercise. Weight loss can help reduce symptoms of osteoarthritis. Similarly, more muscle has a positive impact on the knee function and retardation in progression of disease.

However, you need to consult your doctor to know which type of exercise works best for you. You must be careful in selecting an exercise while keeping your knee position in perspective. Do not exercise without asking your doctor about it.

Alternative Treatment Methods May Also Work

Patients often ask if knee replacement surgery is the only option? Well, in some cases it may be the only option. While, in order cases, your orthopedic surgery doctor may recommend other ways to treat knee pain.

In some patients, you do not need to have a complete knee replacement surgery. The bone surgeon may recommend the patient to undergo partial knee surgery. The orthopedic surgeon recommends partial knee surgery to patients with limited damage to the knee. The disease did not have an impact on the bone and the cartilage remains healthy.

The benefit of total knee replacement surgery is reduced pain and quicker recovery times. However, there exists a risk of a revision surgery if arthritis starts affecting other parts of the knee.

Technological Advancements Took Place in Knee Replacement Surgery

Over the years, advancements in knee replacement surgery techniques have improved a great deal. Patients usually avoided knee replacement surgeries till it became inevitable.

The advancement in materials, technologies, and techniques have had a considerable impact on the quality of treatment. Nowadays, orthopedic surgeons mark precise locations for implanting the implants in the exact location. Over 200 different types of implant sizes are available to help the surgeon better decide the right fit.

Trauma and Injury Has Devastating Impact on Knee Joint

Injury has a bad impact on the knee. Similarly, trauma can have a bad impact on the knee. However, it is seldom a case where the damage could impact the joint surface. For these kinds of issues, the orthopedic surgeon will advise measures like rehabilitation, immobilization, or reconstruction.

However, a very small percentage of patients may need to undergo knee replacement surgery. These are the typical cases where the joint’s surface deteriorates due to the impact of an injury. The condition occurs because of the ligaments not holding the knee together. Doctors recommend patients with such problem to avoid high-impact sports and activities.

Most patients want to facilitate their quick recovery. CPM machines lets them improve their knee joint movement. Consult your doctor if you need a CPM machine or not. In other cases, the doctor may ask you to use special mobility equipment including crutch or walker.

The different exercises help improve mobility of the joint. In some rare cases with no support available at home, the doctor may ask the patient to stay at a rehabilitation facility.

Expectations Immediately After Surgery

Pieces Used in Knee Replacement Surgery

The orthopedic surgery doctor will use implants made of multi-grade plastic and metal. The sealing of these components to your bone will play an important role. The use of bone cement helps set the components in. However, it depends upon the doctor. Sometimes, they may choose to use an approach not involving cement. In this method, the use of porous coating results in growth within the tissue. In some rare cases, the surgeon may simultaneously choose to use both approaches.

The Actual Procedure Behind Surgery for Replacement of Knee

The surgery starts with an incision at the top of the knee. This incision lets the surgeon expose the damaged knee area. The traditional method of surgery required an incision of up to 10 inches. However, the minimally invasive surgery requires shorter incisions. Sometimes, a 4 inches incision is enough to expose the bone.

After incision the orthopedic surgeon will be able to move the kneecap aside. The orthopedic surgery doctor will cut away the damaged portion of the bone and cartilage. After replacing the damaged bone and cartilage, the orthopedic surgery physician will replace them with plastic and metal components.

The orthopedic surgery specialist ensures the components are biologically compatible. The aim is to mimic natural movement of the patient’s knee. It usually takes 1.5 to 2 hours for the orthopedic knee replacement surgery to take place.

It is a thick lubricant driven from rooster comb. This procedure helps overcome inflammation and cushions knee cartilage. This procedure works best in cases of early knee arthritis intervention.

Some of the exercises the doctor may recommend include pilates, cycling, and swimming.
