Equivalent results of medial and lateral parapatellar approach for total knee arthroplasty in mild valgus deformities

par Nathan Stampfli | Mai 1, 2016 | Articles scientifiques, Dr Villa

Abstract Purpose: When performing total knee arthroplasty (TKA) in valgus knee deformities, a medial or lateral parapatellar approach can be performed, but the lateral approach is often considered technically more difficult. The purpose of this study was to...

Metallosis-associated prosthetic joint infection

par Nathan Stampfli | Nov 1, 2015 | Articles scientifiques, Dr Villa

Total joint replacement is the standard treatment of advanced osteoarthritis. Metal-on-Metal (MoM) hip resurfacing and hip arthroplasty are associated with long durability and low rates of dislocations and used to be the standard surgical treatments. Complications due...

Results and complications of single-stage total knee arthroplasty and high tibial osteotomy

par Nathan Stampfli | Juin 25, 2014 | Articles scientifiques, Dr Villa

Abstract Purpose: Long-term survival in total knee arthroplasty (TKA) depends on multiple factors, including restoration of mechanical alignment and obtaining optimal ligament balance. The aim of this study was to document the results of single-stage TKA combined...

Factors influencing posterior tibial slope and tibial rotation in opening wedge high tibial osteotomy

par Nathan Stampfli | Juin 11, 2014 | Articles scientifiques, Dr Villa

Abstract Purpose: Opening wedge high tibial osteotomy (HTO) is an accepted treatment option for medial compartment knee osteoarthritis with associated varus lower limb axis in younger, more active patients. A concern with the use of this technique is that...

Total knee arthroplasty of the stiff knee: three hundred and four cases

par Nathan Stampfli | Déc 21, 2013 | Articles scientifiques, Dr Villa

Abstract Purpose: The purpose of this study was to analyse the results of total knee arthroplasty (TKA) in stiff knees (flexion ≤90° and/or flexion contracture ≥20°). Our hypothesis was that despite having poorer results than those obtained in a « standard »...
