Fracture of the Tibial Baseplate in Bicompartmental Knee Arthroplasty
نویسندگان
چکیده
Introduction. Bicompartmental knee arthroplasty (BKA) addresses combined medial and patellofemoral compartment osteoarthritis, which is relatively common, and has been proposed as a bridge between unicompartmental and total knee arthroplasty (TKA). Case Presentation. We present the case report of a young active man treated with BKA after unsuccessful conservative therapy. Four years later, loosening with fracture of the tibial baseplate was identified and the patient was revised to TKA. Discussion. Although our case is only the second fractured tibial baseplate to be reported, we believe that the modular titanium design, with two fixation pegs, is too thin to withstand daily cyclic loading powers. Light daily routine use, rather than high-impact sports, is therefore advised. Failures may also be related to the implant being an early generation and known to be technically complex, with too few implant sizes. We currently use TKA for the treatment of medial and patellofemoral compartment osteoarthritis.

Fracture of the Tibial Baseplate 16 Years after Miller-Galante II Total Knee Arthroplasty
We report a rare case of tibial baseplate fracture of Miller-Galante II (MG II) prosthesis. We examine the factors that may cause such late fracture and review the literature on radiographic analysis and retrieval studies. A 76-year-old woman, who had undergone bilateral MG II total knee arthroplasty due to rheumatoid arthritis 16 years earlier, presented to our department with a 3-month histor...
متن کاملLong- Stem Total Knee Arthroplasty for Proximal Tibial Stress Fractures in the Elderly Patients
Background: Presentation of proximal tibia stress fracture is not infrequent among elderly patients due to their poorbone stock. Optimal management of patients with severe gonarthrosis of the knee and concurrent tibial stress fracture isnot known yet. In this study we report the outcome of primary total knee arthroplasty (TKA) using stemmed componentsin elderly patients.Methods: Between 2009 an...

In the current study, we present our experience with uncommon acute primary total knee arthroplasty (PTKA)in this patient population.Methods: PTKAs were performed following proximal tibial fractures in 30 consecutive patients over 60 years of agewith osteoporosis or knee...
متن کاملRelationship between Tibial Baseplate Design and Rotational Alignment Landmarks in Primary Total Knee Arthroplasty
This study evaluated the influence of modern tibial baseplate designs when using the anterior tibial cortex as a primary rotational landmark for the tibial baseplate in TKA. Eighty patients undergoing TKA were randomized in two groups. Group 1 included 25 females and 15 males receiving a posterior-stabilized (PS) symmetric tibial baseplate while Group 2 included 24 females and 16 males receivin...
