BACKGROUND AND PURPOSE Uncemented acetabular components in primary total hip arthroplasty (THA) are commonly used today, but few studies have evaluated their survival into the second decade in young and active patients. We report on a minimum 10-year follow-up of an uncemented press-fit acetabular component that is still in clinical use. METHODS We examined the clinical and radiographic resul...

Any operation induces an elevation in the level of serum C-reactive protein (CRP). After hip and knee arthroplasty the maximal values are seen on the second and third postoperative days, after which the CRP decreases rapidly. There is no difference between patients with cemented or uncemented prostheses. Major postoperative complications may cause a further increase in CRP levels at one and two...

Ochronotic arthropathy is a manifestation of longstanding alkaptonuria. With increasing age, an accumulation of pigment deposits of homogentisic acid in the joint cartilage results in ochronotic osteoarthritis. We present a case of a 62-year-old female who underwent staged left uncemented total hip and right cemented total knee arthroplasty for osteoarthritis secondary to ochronosis.

Acute compartment syndrome (ACS) of the thigh is an uncommon condition usually treated surgically by emergency dermofasciotomy. We report a rare case of acute delayed compartment syndrome of the anterior compartment of the thigh following an uncemented Total Hip Replacement (THR). Surgical decompression was performed and patient had full recovery.

A rare case of sciatic nerve palsy in an uncemented modular hip arthroplasty is described. We believe that a delay in recognizing liner dissociation causing granuloma was responsible for the nerve palsy. Delay in diagnosis can be avoided by a careful inspection of prereduction and postreduction radiographs.

Our aim was to determine if the serum levels of bone-resorbing cytokines (IL-1beta, TNF-alpha, IL-6, GM-CSF) are altered in patients with aseptic loosening of a total hip prosthesis, and if such levels are influenced by the type of implant. We determined cytokine levels in sera from 35 patients before revision for failed total hip arthroplasty and compared them with those in 25 healthy donors. ...

A variety of conditions may lead to arthritis of the hip during adolescence. Although uncommon, total hip arthroplasty may occasionally be necessary for treatment of end-stage disabling arthritis of the hip in the young. There is paucity of information documenting the outcome of uncemented total hip arthroplasty in adolescents. We report our experience with total hip arthroplasty in patients un...

BACKGROUND Uncemented fixation of components in joint arthroplasty is achieved primarily through de novo bone formation at the bone-implant interface and establishment of a biological and mechanical interlock. In order to enhance bone-implant integration osteoconductive coatings and the methods of application thereof are continuously being developed and applied to highly porous and roughened im...

UNLABELLED Uncemented fixation of implants to bone is a proven technology in traditional hip arthroplasty surgery. However, cement fixation is currently the standard method for the femoral component in hip resurfacing. The purpose of this study was to evaluate the performance of uncemented fixation of the femoral component in the first 100 fully porous-coated metal-on-metal hip resurfacing arth...

Background Subsidence of cementless femoral stems in hemiarthroplasty (HA) and increased fracture rates are ongoing concerns of orthopedic surgeons when treating fractures in very old patients. Additionally, bone cement implantation syndrome may result in perioperative cardiac or pulmonary complications, especially in older patients, leading to morbidity and mortality. This study was performed ...
