Stress fracture of the femoral component is a rare complication following total knee arthroplasty. We report one such complication which occurred 6.5 years after primary implantation of an uncemented meniscal Low Contact Stress (LCS) prosthesis. The fracture affected the medial condyle of the femoral component, and a large osteolytic lesion was present in the underlying femoral condyle. The pat...

We measured polyethylene wear in 231 porous-coated uncemented acetabular cups. We divided the hips into two groups according to the fixation of the femoral component, by cementing (n = 97) or press-fit (n = 134). Follow-up was from three to five years. The patients in two sub-groups were matched for weight, diagnosis, sex, age and length of follow-up. The linear wear rate of cups articulated wi...

Concomitant ipsilateral intracapsular and extracapsular fractures of the femoral neck are rare injuries with only 14 cases described in the literature as single case reports. We present three cases that were successfully and uniquely treated by uncemented hip arthroplasties. Two patients underwent complex primary uncemented total hip replacements, and one patient underwent an uncemented bipolar...

OBJECTIVE To describe a case series using a combination of narrative, graphical exploratory analysis and Bayesian Network modeling. METHODS Case series with 34 patients undergoing uncemented and hybrid arthroplasty procedures secondary to hip pain or fracture secondary to metastatic disease or multiple myeloma. RESULTS The most common tumors included gastrointestinal, multiple myeloma and b...

We compared the performance of uncemented trabecular metal tibial components in total knee replacement with that of cemented tibial components in patients younger than 60 years over two years using radiostereophotogrammetric analysis (RSA). A total of 22 consecutive patients (mean age 53 years, 33 to 59, 26 knees) received an uncemented NexGen trabecular metal cruciate-retaining monobloc tibial...

Uncemented modular cups are the preferred implants for primary total hip arthroplasty (PTHA). Cemented all-polyethylene cups are still popular in Europe; however, the high prevalence of radiographic loosening observed after the first decade of implantation in young patients and the concept of ‘cement disease’ collaborated to generate skepticism about the use of cement for acetabular fixation. S...

We aimed to assess the risk to surgeons of blood splatter during total hip arthroplasty. Hoods from personal protection systems used in 34 consecutive total hip replacements were collected and the area of blood splatter was measured and compared to goggles and visors. Thirty one primary THA's (13 cemented, 4 hybrid, 14 uncemented) and 3 revisions (1 hybrid, 2 uncemented) were collected. Splashe...

INTRODUCTION Posterior hip dislocation of the hip with acetabular fracture is a challenging problem to treat. Such dislocations are associated with avascular necrosis of the femoral head if neglected. Managing such conditions with total hip replacement (THR) is very difficult because of associated altered anatomy. CASE PRESENTATION We hereby report a two-year neglected hip dislocation with as...

Background and purpose - Total hip replacement (THR) is the preferred method for the active and lucid elderly patient with a displaced femoral neck fracture (FNF). Controversy still exists regarding the use of cemented or uncemented stems in these patients. We compared the effectiveness and safety between a modern cemented, and a modern uncemented hydroxyapatite-coated femoral stem in patients ...

BACKGROUND The uncemented Nottingham Total Shoulder Replacement prosthesis system (Nottingham TSR) was developed from the previous BioModular shoulder prosthesis taking into consideration the causes of the initial implant's failure. We investigated the impact of changes in the design of Nottingham TSR prosthesis on its survivorship rate. METHODS Survivorship analyses of three types of uncemen...
