Why Is Partial Knee Replacement Performed
The most common reason for partial knee replacement is single-compartmental knee damage from advanced osteoarthritissignificant wear and tear on the knee joint. People with knee have damaged cartilage, which is the shock absorber in joints. When the cartilage begins to wear out, the joint movements arent as smooth, and the bones begin to rub against each other causing pain and stiffness. Knee replacement is a treatment option for most people after a course of nonsurgical treatments arent successful at relieving the pain and discomfort or your symptoms are interfering with your daily activities. The goal of knee replacement is to make knee movement pain-free, smooth and stable.
Although total knee replacement is a common procedure, people who have arthritic damage in only a single part, or compartment of the knee may be good candidates for partial knee replacement surgery. The medical terms for the different compartments are medial , lateral , and patellofemoral .
One of the main benefits of partial knee replacement is the preservation of healthy cartilage, bone and ligaments in the unaffected parts of the knee. It is usually a minimally invasive operation with smaller incision instead of one larger one for open knee replacement. With a half-knee replacementoften the medial sidethere is a possibility of further wear and tear on the other half. This would require replacing the entire knee joint in another surgery.
How Is Partial Knee Replacement Performed
You will have surgery in a hospital or orthopedic specialty surgery center. Before your surgery date, discuss your anesthesia options with your surgeon. You may have a choice of regional anesthesia, which is when you are awake but numb from the waist down. The surgical team will most likely give you a sedative to make you groggy and relaxed during the procedure. The other option is to be completely asleep using general anesthesia.
The will make a cut in your knee about three to five inches long to ensure the damage is confined to just one part of your knee. Typically, knee imaging beforehand will determine the extent of damage, but if there is more damage to the knee than expected, you may need a total knee replacement instead. Your surgeon should discuss this possibility with you in advance.
Partial knee replacement surgery is less invasive than total knee replacement, and the recovery is much quicker and easier. Youll be able to start moving again right away. Depending on your overall health and how you fare after surgery, you may have a hospital stay of only one to two days.
Advantages Of Partial Knee Replacement
Multiple studies have shown that modern unicompartmental knee replacement performs very well in the vast majority of patients who are appropriate candidates.
The advantages of partial knee replacement over total knee replacement include:
- Quicker recovery
- Less pain after surgery
- Less blood loss
Also, because the bone, cartilage, and ligaments in the healthy parts of the knee are kept, most patients report that a unicompartmental knee replacement feels more “natural” than a total knee replacement. A unicompartmental knee may also bend better.

Knee Replacement Pain After Three Months
Swelling and bruising can continue for three months or more following knee replacement surgery. However, it varies from patient to patient and depends on the condition you were in before surgery. Many patients are back to their activities without the pain they had before surgery by this stage of recovery.
If you find that any movement or activity is still exceedingly painful after three months, you may be experiencing chronic pain. Chronic pain is defined as pain persisting for three months or longer. Its a condition that affects roughly 20% of knee replacement surgery patients. It can develop and increase in intensity in the weeks and months following surgery. This can have a huge impact on your overall quality of life. Talk to your doctor for help.

As part of your rehabilitation at Summit Healthcare, we will include training you how to kneel on your repaired knee. This is a completely safe movement and patients usually only stop kneeling out of fear of damaging their repaired knee. The problem with this overly restrictive line of recovery is that kneeling is important for many movements and activities. For instance, older patients need to be able to get up off the floor in case of a fall. If they cannot kneel, they cannot get back up. Other activities from gardening to household chores require kneeling. You will not need to lose this ability because of your partial knee replacement.

Partial knee replacement recovery time is shorter. Thanks to its minimally invasive nature which requires less time to heal.
For young patients, the recovery timeline is not only quicker but also less painful. This is contrary to full surgery.

Compared to total knee replacement surgery, partial surgery is also quite affordable. This is because it is less demanding.
Apart from its knee replacement surgery recovery time the success rate is also high. This means that it is much more effective.
Less Blood Loss
Partial knee surgery uses very small dissection which leads to less loss of blood. Because of this, no blood transfusion is often needed and most patients find it easy to undergo the whole process.
