Aims and Objectives Inexplicable pain to the medial proximal tibia is a frequent finding leading to revision after unicondylar knee arthroplasty (UKA). This study is an effort to find out, if there are any differences between mobile (MB) and fixed bearing (FB) UKA designs in terms of resulting strain in the medial proximal tibia as measured in an i...
Article
Background Unexplained pain in the medial proximal tibia frequently leads to revision after unicondylar knee arthroplasty (UKA). As one of the most important factors for osteogenic adaptive response, increased bone strain following UKA has been suggested as a possible cause. Questions/purposes In this study we: (1) performed a cadaver-based kin...
Article
Purpose The purpose of this study was to assess whether unicompartmental knee arthroplasty (UKA) results in better patient-reported and clinical outcome than total knee arthroplasty (TKA). The study hypothesis was UKA yields better patient-reported and clinical outcomes than TKA. Methods Our prospective cohort study compared patients who underwent...

Introduction Unexplained pain in the anteromedial region of the proximal tibia is a common challenge following unicondylar knee arthroplasty (UKA), which may even lead to revisions. Although abnormal strain distribution and bone-implant motion have been suggested as potential factors, the specific reason is not yet clear [1]. Therefore, this study...
Article
Purpose: To present a clinical validation of a novel technology called "3X" which allows for 3D prosthesis planning and treatment evaluation in total knee arthroplasty (TKA) using only 2D X-ray radiographs. Materials and methods: After local institution review board approvals, 3X was evaluated on 43 cases (23 for preoperative planning and 20 for...

Introduction: Fixed-bearing unicompartmental knee arthroplasty (UKA) closely replicates native knee kinematics. As few studies have assessed kinematics following mobile-bearing (MB) UKA, the current study aimed to investigate whether MB UKA preserves natural knee kinematics. Materials and methods: Seven fresh-frozen full-leg cadaver specimens we...
Article
Background: The recently reintroduced bicruciate retaining Total Knee Arthroplasty (BCR TKA) is an effort to reproduce kinematics closer to the native knee. However, there is no data on appropriate balancing with this implant. Balancing is crucial and challenging as medial and lateral polyethylene (PE) inlays are modular, which allows for placemen...
Article
Purpose: The recently reintroduced bicruciate-retaining Total Knee Arthroplasty (BCR TKA) is an interesting approach in the quest for close replication of knee joint biomechanics and kinematics closer to the native knee. Therefore, this study aimed at providing a detailed biomechanical view on the functional resemblance of BCR TKA to the native kn...

IntroductionTotal knee arthroplasty (TKA) is a successful procedure for the management of osteoarthritis (OA) of the knee. Axial plane deformities are more common than suspected in patients presenting with osteoarthritis of the knee joint. Recent research has indicated that torsional deformities could play an important role in the development of an...
Article
Purpose: Balancing mobile-bearing (MB) unicondylar knee arthroplasty (UKA) is challenging. If performed improperly, potential complications include pain, implant loosening, or progression of osteoarthritis in the preserved compartment. The purpose of this study was to document effects of improper balancing on knee kinematics and joint contact stre...
Poster
Results agree closely with those previously observed for fixed-bearing UKA: optimal balancing is difficult and understaffing results in kinematics that are closest to the native knee.
Article
We report the case of a 32-year-old male patient involved in a road traffic accident in which he sustained a grade II open supra- and intercondylar fracture of the left distal femur with substantial bone loss of the lateral femoral condyle and trochlea (AO classification type 33 C3). Normal knee function was no longer possible, as the patella was t...
Article
Background: Unicondylar knee arthroplasty (UKA) is believed to lead to less morbidity and enhanced functional outcomes when compared with total knee arthroplasty (TKA). Conversely, UKA is also associated with a higher revision risk than TKA. In order to further clarify the key differences between these separate procedures, the current study assess...

Purpose: Two design concepts are currently used for unicondylar knee arthroplasty (UKA) prostheses: fixed bearing (FB) and mobile bearing (MB). While MB prostheses have theoretical advantages over their FB counterparts, it is not clear whether they are associated with better outcomes. A systematic review was conducted to examine survivorship diffe...
Article
Sporting activities that involve repetitive stress to muscle compartments can elicit chronic exertional compartment syndrome. Its occurrence in the lower leg muscle compartments is most common, but other locations are less well known and the pathophysiology is not completely understood. In motocross racers, chronic exertional compartment syndrome c...
Article
Unicompartmental knee arthroplasty (UKA) is known to be a viable procedure allowing for preservation of the intact compartments and delivering excellent function at long-term follow-up. The primary purpose of this single-surgeon study was to analyse the survivorship of a fixed bearing UKA in patients younger than 60 years. From all UKAs implanted b...

The purpose of this prospective study was to demonstrate the findings of MRI in motocross racers with chronic exertional compartment syndrome (CECS) of the forearm. Racers with proven CECS and without CECS and male individuals not involved in strenuous activities with the forearm were included. Signal intensity (SI) and signal-to-noise ratio (SNR)...

High counts of wear particles and activated macrophages are strong predictors of prosthetic loosening in total joint arthroplasty patients. The tissue response, dominated by macrophages, with production of inflammatory mediators and matrix-degrading enzymes, triggers a self-accelerating cycle of osteolysis, ultimately resulting in failure of the ar...

The American Society of Anesthesiologists Physical Status Classification System (ASA) ranks patients for risk of adverse events during a surgical procedure. The ASA classification is used as a surrogate for the patient's underlying severity of illness and has been recommended for use in Surgical Site Infection (SSI) and risk stratification. We asse...

Risk stratification has proven to be a useful tool in surgical site infection prevention. The duration of the surgical procedure has been recommended for use in surgical site infection (SSI) risk stratification (Infect Control Hosp Epidemiol 20:247-248, 1999). A retrospective analysis of 6489 patients who underwent total knee replacement (TKR) betw...
Article
Six thousand four hundred eighty-nine knee replacements were done in 6120 patients at the authors' institution between 1993 and 1999. Operations were done in a theater with vertical laminar flow and with the surgical team using body exhaust suits. Of these knee replacements, 116 knees became infected and 113 were available for followup. One hundred...
