Prosthetic surgery

Also called arthroplasty, it allows for improvement of the joint function and relieve pain that people with joint problems endure.

The vast experience of our professionals and the improvement of prosthesis enables us to achieve very good results and patients can see an upgrade to their quality of life, rather than the intense pain and functional limitations of a damaged joint.

We commit towards the sustained improvement and apply innovative surgical solutions. That’s why we have incorporated to our hip prosthesis surgery a new procedure (Maash) that, because of being less aggressive than the regular arthroplasty, allows for a quicker recovery (2-3 days) and greatly decreases the risk of complications.

Also, we are among the advanced centers when it comes to arthroplasty surgery check-up (placing of a new prosthesis), a skill-demanding procedure. Our extensive experience, the implementation of the latest technical advances and the introduction of state of the art materials (like tantalum) makes our professionals renowned within the field.

Hip prosthesis

Total hip prosthesis is one of the newest developments in orthopedic surgery of the last century, as it allows for the substitution of one of the most prominent joints for bipedalism and walking when it is badly damaged (inflammation or infection) for an artificial joint (prosthesis).

Osteoarthritis, the process where the cartilage of the joint wears and tears, is the most frequent symptom for the placing of a total hip prosthesis, but the joint itself can be heavily damaged due to fractures, infections, rheumatoid arthritis… the surgical intervention is well suited when the damaging of the joint is so severe that causes serious and persistent pain to the patient and it incapacitates any movement of the leg.

The kind of prosthesis used will depend on age and the general status of the patient. Usually, though, we place total hip prosthesis made of titanium coated in hydroxyapatite –a natural component found in bones–, making possible the biological anchoring of the prosthesis to the bones.

More information

The surgical procedure consists in replacing the upper, sphere-shaped end of the femur for another one made of metal or ceramic, usually joined to a titanium carving, inserted inside the bone. Within the spherical cave of the pelvis we place a dome made of metal or polythene (high-resistant plastic) named cotyle.

The materials used in the total prosthesis are designed to allow for movements similar to a real joint. The components are usually made of a metallic component that fits perfectly inside a device made of plastic, ceramic or metal. Various types of metal are commonly used, like stainless steel, cobalt-chrome alloys or titanium. The plastic half is always a high-density polythene because of its durability and wear resistance.

The attachment of the elements of the prosthesis to the bone can be achieved directly or through a cement-like substance. We usually coat our total hip prosthesis in hydroxyapatite. Hydroxyapatite is one of the many things inside our bones, and allows for a biological anchoring to the bone, which is highly resistant. However, if the injuries are so severe that the bone quality is insufficient, we will have to resort to cemented prosthesis.

Before the procedure

From the moment that we consider the possibility of replacing a knee or a hip for a total prosthesis, it is important to notify the patient that we need them with the best conditions possible and they will need to have a healthier lifestyle, losing weight in cases of obesity and have a pre-operatory check-up where we will study the analytics, cardiac function and the state of the lungs. The anesthesiologist will explain the result of this study and the procedure inside the surgical area.

After the procedure

We have to encourage the patient to use their new joint as soon as possible after the procedure. Our physiotherapists will help you, give you the needed advice to recover full movement and, progressively, the muscular strength. After the procedure, you will be taught how to use a crutch the firsts days, how to sit and stand up from a chair or the WC, get in and out of the car… until you recover your normal status and forget you have a prosthesis.

Knee prosthesis

This is a surgical procedure where we replace the inner part of the femur and the upper part of the shinbone for a prosthetic component made of metal and plastic. The procedure is done through a cut in one of the faces of the knee. The main desired goal is to make the patient’s pain go away from this joint that, whether for aging or inflammatory processes, hinders the possibility of having a normal life.

The procedure lasts for about 1 to 2 hours, and the recovery inside the hospital is normally 7-10 days. The rehabilitation specialists and the physiotherapist will help you regain progressively the movement of the treated joint.
