Implant survival following primary total hip arthroplasty : With special interest in uncemented acetabular components and liners
(Turun yliopisto, 2021-05-28)
Total hip arthroplasty (THA) isregarded as the operation of the century. A successful THA is a combination of adequate surgical technique with appropriate implants performed for carefully selected patients. Orthopedic ...
Risk factors and risk prediction models for early complications following total hip arthroplasty
(Turun yliopisto, 2023-06-02)
Treatment of end-stage hip osteoarthritis was revolutionized in the 1960s with the newly invented low-friction total hip arthroplasty (THA). Since then, an increasing number of both primary and revision THAs have been ...
Unicompartmental and total knee arthroplasty in the treatment of knee osteoarthritis
(Turun yliopisto, 2021-11-12)
Even though total knee arthroplasty has been a highly successful operation, as many as 20% of patients are somewhat dissatisfied with their prosthesis. In at least 25% of patients, the pattern of osteoarthritis is isolated ...
Radiostereometric analysis in total hip arthroplasty and hip fracture patients
(Turun yliopisto, 2021-10-15)
Complications related to primary total hip arthroplasty (THA) are relatively rare but still impose a significant burden on the recovery of individual patients and incur significant costs to the healthcare system. Research ...
Radiostereometric analysis of initial femoral stem migration in cementless total hip arthroplasty of postmenopausal women : Exploring contributing factors in initial femoral stem migration
(Turun yliopisto, 2020-10-23)
In cementless total hip arthroplasty (THA), femoral stems rely on the initial press‐fit fixation against the cortical bone to achieve osseointegration. In aging women, structural changes of the proximal femur may jeopardize ...
Outcome of metal-on-metal hip arthroplasty: with special interest in repeated whole blood chromium and cobalt measurements
(Turun yliopisto, 2022-10-21)
It is now more than a decade since the full scale of problems with modern large diameter (LD) metal-on-metal (MoM) hip arthroplasties was recognized, leading to the withdrawal of most MoM implants around 2012. About 1.5 ...
Bone quality and mesenchymal stromal cell capacity in total hip replacement: Significance for stem osseointegration measured by radiostereometric analysis
(Annales Universitatis Turkuensis D 1244Turun yliopisto, 2016-09-23)
Immediate implant stability is a key factor for success in cementless total hip arthroplasty (THA). Cementless techniques were originally designed for middle-aged patients with normal bone structure and healing capacity, ...
Risk of dislocation, cancer and mortality following hip arthroplasty
(Turun yliopisto, 2019-11-22)
Since the introduction of the first modern hip implants in the 1960s, total hip arthroplasty (THA) and hemiarthroplasty (HA) have continued to evolve towards minimizing implant-related complications. Developments in surgical ...
Results of ReCap-M2a-Magnum Metal-on-Metal Total Hip Arthroplasty
(Turun yliopisto, 2020-05-08)
Metal-on-polyethylene (MoP) bearing surfaces were standardized by Sir John Charnley and are still considered the gold standard in total hip arthroplasty (THA). Nevertheless, MoP THAs caused polyethylene wear and led to ...
Reducing dislocations of total hip arthroplasty
(Turun yliopisto, 2022-03-04)
Dislocation is one of the most common complications following total hip arthroplasty (THA). There are several concepts that can be used to reduce the number of dislocations, including elevated liners, larger femoral heads, ...
