Advances in Complete Artroplasty on the Knee and Hip

Dr. Guillermo Claverie D.
Orthopedic Surgeon

Complete arthroplasty on the hip and knee has become the most successful surgery around the world, and Guatemala is no exception. It is a surgery that is constantly being innovated with new metals as well as new sterilization techniques on the plastics that are used. This innovation has changed the idea that the implant could only last from 5 to 10 years. At the same time, the surgical technique that uses specialized instruments; the new and innovative procedures that are minimally invasive; as well as the use of new materials such as ceramic and metal with metal; bigger femoral heads; and the surgery to completely cover the femoral head when hip prosthetics are needed, have brought better stability. This may also be a benefit for younger people who need the surgery on their hip and knee joints.

In a knee arthroplasty the unicompartmental prosthetic technique allows an additional mobility option for young patients, as well as a fast recovery. The minimally invasive technique can be accomplished with the new design of the surgical instruments which lowers the size of the block cuts. On knee replacement cases, there is less trauma on the soft tissue which allows patients to have faster mobility as well as a speedy recovery.

Of course this procedure requires great deal of preparation on the patients side, since most of them are elderly and minimally invasive surgery techniques require certain conditions to be applied. This is the case of obese patients, and a thorough study on diabetic or rheumatoid arthritic patients.


For a complete hip arthroplasty it is important to mention that the use of cement bone to secure the prosthesis to the hip has been completely abandoned, great results have been obtained with hip prosthetics that do not use cement, using new materials such as titanium and more recently tantalum. Such results have not been obtained with knee replacements were cement is still used to keep the prosthetic in place with great results. Therefore, knee technology with no cement has taken more time to study, and the results need to compete with the excellent results already obtained on cemented knee prosthetics.

Dr. Guillermo Claverie has done this surgery for more than 15 years, with over 3,000 arthroplasties, using specific protocols to prevent infection during treatment, preventing deep vein thrombosis, as well as reducing operation time. His results have been competing with the best specialized centers in the United States.

Among his biggest accomplishments, he established the Guatemalan-American Advanced Orthopedic Surgery Foundation (Fundación Guatemalteco Americana de Cirugía Ortopédica Avanzada-FUNDAORTO-) a non-lucrative institution that provides surgical solutions to Guatemalans that have osteoarthritis and require knee and hip replacements, and personally performing an average of 200 surgeries per year for people with a low income, where pre and post operation protocols are applied by Dr. Claverie himself, with excellent results.
