Partial Knee Replacement

A partial knee replacement in Delhi is a surgery that can be considered for the treatment of severe knee arthritis.

Traditionally, patients have undergone total knee replacements, placing a metal or plastic implant on them. Today, with innovative technology, total knee replacement is not necessary, usually a partial knee replacement is sufficient.

What is partial knee replacement?

Partial knee replacement is also known as the Oxford knee. The knee consists of three separate compartments and if only one compartment is damaged, partial knee replacement in West Delhi can be performed.

Your orthopaedic surgeon in Delhi will determine if you are a good candidate for this type of surgery or if you need a total replacement.

The idea of this surgery is to replace only the damaged part of the joint and leave the other healthy parts intact. Replacement can occur on the side (external) or medial (internal) of the knee.

Patients who are good candidates for this type of surgery must be over 55 years old, not obese and lead a relatively sedentary life.

In many cases arthritis is widespread and partial knee replacement is not possible. Damage to joint cartilage is so severe that this type of surgery cannot be performed. In this case orthopaedic in Dwarka recommends to replace a total knee.

If partial knee replacement in Delhi is performed for someone who is a poor candidate, the risk of failure is high. In this case a conversion to a total knee replacement is required.

Total or regional anesthesia is used.

What are the risks of partial knee replacement?

Risks of partial knee replacement include:

• Failure to comply with the procedure
• Fluid buildup in the knee
• Blood clots
• Nerves and damage to blood vessels
• Knee pain
• Sympathetic dystrophy reflects

What are the benefits of partial knee replacement?

This procedure is minimally invasive surgery. The advantages are:

• Faster recovery time
• Smaller incision
• Less blood loss
• Less pain
• More natural movement

What to expect after surgery?

The recovery time after this surgery is faster than for a total knee replacement. It varies, but you will usually be able to walk, drive and do all the things you did before two to three weeks after surgery.

Consult with your orthopaedic in Delhi, because the damage at this stage can lead to serious problems, causing surgery failure.

You will need physical therapy for four to six months after surgery. Your orthopedic in Delhi will also prescribe pain relievers, as you will have mild to moderate pain during your recovery time.

These implants showed a high success rate with results of 95% at age 15 and beyond.

Partial Hip Replacement Implants

Partial hip replacement implants are generally used to treat a hip fracture in an elderly patient, rather than a hip damaged by osteoarthritis, for which total hip replacement is a treatment. It is usually an emergency surgery that is essential due to a fall or other accident that fractures the hip. Partial hip replacement surgery in Delhi is more correctly known as "hemiarthroplasty," or "hemi" means half of a joint because it replaces only the spherical part of the hip joint, not the cavity portion. A total hip replacement orthopedic implant, on the other hand, replaces acetabulum and the ball of the joint.

The most common reasons for fractures in the elderly are that they are fragile and not in good health. Your bones may be fragile due to osteoporosis, or they may be unstable in your feet and are more likely to stumble. It has been theorized that, at times, the hip bone of an older person can be weakened in such a way that it can really give in, causing it to fall, instead of the fall causing the hip to break, says orthopaedic in Delhi.

The treatment of hip fractures is dictated by the classification of the fracture and the viability of the head of the femur. Your surgeon will determine if your hip fracture can be repaired, or if the expected state of health and longevity qualify you for a partial hip replacement in Delhi, or if other aspects such as advanced osteoporosis require the need for a total hip replacement.

Partial Hip Implants

Unlike the total hip replacement implants that have a separate ball and stem, the classic partial hip replacement implants, pioneers in the 1960s and still in use today, include a complete ball design and stem. The unipolar design features a solid stem and a metal ball that replaces the femoral head and upper femur (thigh bone). The Thompson and Austin Moore prostheses are common examples of unipolar design, where hip movement occurs directly between the acetabulum (the hip cavity) and the prosthesis. Other more recently developed partial hip replacement implants are modular, allowing different combinations of head, stem and neck length, explains orthopaedic in Delhi.

Modular and unipolar devices are exclusive to partial hip replacement procedures and would not be considered as treatment for an arthritic hip, which needs a total hip replacement in west Delhi.

1. An Austin Moore implant that is used without cement (bone grows through the holes)
2. A Thompson prosthesis that is usually placed with bone cement.
3. A modular prosthesis with a separate spherical head.

Like total hip replacement implants, partial hip replacement implants come in cementless and cemented versions. The means, the orthopedic implant can be placed in position either with the use of bone cement or without its use. One of the limitations of cementless fixation is the risk of instability and loosening due to possible poor bone quality in elderly and elderly patients.

Procedure and Recovery

Like a total hip replacement, the femoral head of the bone is removed from the upper thigh and the shaft is cut to accept the stem of the partial implant. The device is inserted and the surgical opening is closed, usually with vacuum drains to remove any excess blood drainage.

Recovery can be problematic if you are elderly and have poor general health. Several patients manage to have a good quality of life again, however, almost the same number of people end up requiring attention for a long time due to problems related to age and health. In general, partial hip replacement surgery in west Delhi is a less complex operation than total hip replacement, and generally provides satisfactory results for less active elderly patients with less life expectancy. In the case of more active elderly patients with a longer life expectancy, a total hip replacement is preferred for displaced femoral neck fractures.
