Hip replacement surgery has gone through tremendous evolution since the first procedure in 1840. In the past five decades the advances that have been made in technology, advanced and smart materials innovations, surgical techniques, robotic surgery and methods of fixations and sterilization, facilitated hip implants that undergo multiple design revolutions seeking the least problematic implants and a longer survivorship. Hip surgery has become a solution for many in need of hip joint remedy and replacement across the globe. Nevertheless, there are still long-term problems that are essential to search and resolve to find the optimum implant. This paper reviews several recent patents on hip replacement surgery. The patents present various designs of prostheses, different materials as well as methods of fixation. Each of the patents presents a new design as a solution to different issues ranging from the longevity of the hip prostheses to discomfort and inconvenience experienced by patients in the long-term.

Elderly Recipients

The success of hip implants with elderly recipients has encouraged surgeons to increasingly perform hip replacement surgery on younger, more active patients as well. The condition that causes hip prostheses to loosen is known as osteolysis. While the problem affects only a relatively small set of recipients now, it may well grow as hip replacement surgery encompasses a wider range of eligible patients. A research group at the University of Leeds in the United Kingdom says it has patented a ceramic-on-metal hip prosthesis that produces one-tenth the wear particles of currently available hip replacement joints. The prosthesis has been licensed to a prosthetic manufacturer and is about to enter clinical trials in Europe. Some companies produce highly cross-linked polyethylene, either by thermal treatment or by radiation. Stryker Orthopaedics has Crossfire hip implants using highly cross-linked polyethylene cups against a metal ball. The company developed a ceramic-on-ceramic joint replacement, which it commercialized in 2003. The new Trident joint uses bearing surfaces of alumina ceramic. The company claims it has scratch resistance, low wear rates, good wettability for lubrication, and no ion release.

Tumour Formation

SummaryCase description: A 10-year-old female Belgian Teruven dog was presented to our clinic for total hip revision following a diagnosis of implant (cup) failure with metallosis and abdominal pseudotumour formation. The patient had a cementless metal-on-polyethylene total hip replacement performed nine years prior to presentation.Clinical findings: The clinical findings, including pseudotumour formation locally and at sites distant from the implant and pain associated with the joint replacement, were similar to those described in human patients with this condition. Histopathological, surgical, and radiographic findings additionally supported the diagnosis of metallosis and pseudotumour formation.Treatment and outcome: Distant site pseudo -tumours were surgically removed and the total hip replacement was explanted due to poor bone quality. The patient recovered uneventfully and has since resumed normal activity.Conclusion: In veterinary patients with metal-on-polyethylene total hip implants, cup failure leading to metallosis and pseudo-tumour formation should be considered as a potential cause of ipsilateral hindlimb lameness, intra-pelvic abdominal tumours, or a combination of both. These clinical findings may occur years after total hip replacement surgery.

Total Hip replacement offers complete resolution of symptoms and restoration of Hip function. The long-term success of hip replacement primarily depends on wear and osteolysis resulting from the bearing surfaces used in hip replacement surgery. Different bearing surfaces have been used in hip replacements with variable success rate. Traditional combinations include, metal on polyethylene, ceramic on Polyethylene and metal on metal articulations. Ceramic on ceramic Bearing couple is a relatively newer combination recommended for younger patients requiring Total hip Arthroplasty. Ceramics have the lowest wear rate and are showing promising long-term results in international literature. We report the use of this bearing surface for the first time in Pakistan. Continuous...
