No association between blood count levels and whole-blood cobalt and chromium levels in 1,900 patients with metal-on-metal hip arthroplasty

Acta Orthopaedica, 2020
Background and purpose — The accelerated wear of poorly functioning metal-on-metal (MoM) hip implants may cause elevated whole-blood cobalt (Co) and chromium (Cr) levels.

Gluteal muscle fatty atrophy is not associated with elevated blood metal ions or pseudotumors in patients with a unilateral metal-on-metal hip replacement

Acta Orthopaedica, 2016
Background and purpose — There are no international guidelines to define adverse reaction to metal debris (ARMD). Muscle fatty atrophy has been reported to be common in patients with failing metal-on-metal (MoM) hip replacements.

Impact of keel saw blade design and thickness on the incidence of tibial plateau fracture and tibial implant-loosening in cementless medial UKR

BMC Musculoskeletal Disorders, 2022
Background Tibial plateau fractures and tibial implant- loosening are severe complications in cementless unicompartmental knee replacement (UKR). The tibial keel preparation is particularly demanding and different saw blades can be used.

Mild knee osteoarthritis predicts dissatisfaction after total knee arthroplasty: a prospective study of 186 patients aged 65 years or less with 2-year follow-up

BMC Musculoskeletal Disorders, 2021
Background and aims The incidence of total knee arthroplasty (TKA) is increasing, especially among younger working-age patients. However, dissatisfaction rates in this population are higher than among older patients.

Joint aspiration for diagnosis of chronic periprosthetic joint infection: when, how, and what tests?

Arthroplasty, 2023
Diagnosing chronic periprosthetic joint infection (PJI) requires clinical suspicion in combination with both serological and synovial fluid tests, the results of which are generally applied to validated scoring systems or consensus definitions for PJI ...

The Replace Operator [PDF]

Proceedings of the 33rd annual meeting on Association for Computational Linguistics -, 1995
This paper introduces to the calculus of regular expressions a replace operator and defines a set of replacement expressions that concisely encode alternate variations of the operation. Replace expressions denote regular relations, defined in terms of other regular expression operators. The basic case is unconditional obligatory replacement. We develop

Lack of evidence—the anti-stepwise introduction of metal-on-metal hip replacements: A systematic review and a comparative assessment of the literature and registry data

Acta Orthopaedica, 2017
Background and purpose — Orthopedics and especially joint replacement surgery have had more than their fair share of unsuccessful innovations that have violated widely endorsed principles for the introduction of new surgical innovations.

Directed replacement [PDF]

Proceedings of the 34th annual meeting on Association for Computational Linguistics -, 1996
This paper introduces to the finite-state calculus a family of directed replace operators. In contrast to the simple replace expression, UPPER -> LOWER, defined in Karttunen (ACL-95), the new directed version, UPPER @-> LOWER, yields an unambiguous transducer if the lower language consists of a single string.

Mid-term progressive loosening of hydroxyapatite-coated femoral stems paired with a metal-on-metal bearing

Journal of Orthopaedic Surgery and Research, 2019
Background Several hydroxyapatite (HA)-coated femoral stems from a single manufacturer were identified to have aseptically loosened at mid-term follow-up despite prior radiographic appearance of osseointegration.

High Incidence of Recurrent Patellofemoral Crepitus in Total Knee Arthroplasty Patients Following Arthroscopic Debridement

Arthroplasty Today, 2023
Background: Patellofemoral crepitus is an unfavorable complication following total knee arthroplasty (TKA) with a posterior-stabilized (PS) implant.
