OBJECTIVE The purpose of this study was to explore the midterm clinical outcomes of unicompartmental knee replacement (UKR) for medial knee arthropathy through a minimally invasive approach (MIA). METHODS From January 2006 to June 2010, 442 consecutive patients (485 knees) were included in the study. All patients underwent MIA-UKR with the mobile bearing Oxford phrase III prosthesis. The inci...

PURPOSE Tibial radiolucent lines (RL) are commonly seen in cemented unicompartmental knee replacement (UKR). In the postoperative course, they can be misinterpreted as signs of loosening, thus leading to unnecessary revision. Since 2004, a cementless OUKR is available. First studies and registry data have shown equally good clinical results of cementless OUKR compared to the cemented version an...

Abstract Introduction Unicompartmental knee replacement (UKR) results in less morbidity, early mobilisation, and better PROMs appropriately selected patients. There has been a steady increase the number of fixed bearing UKRs NJR. We present single anaesthetic bilateral cemented medial UKR. Method All patients undergoing UKR using ZUK prosthesis (LIMA, UK) under between March 2013 2019 were incl...

Failure of a unicompartmental knee replacement (UKR) may be caused by progressive osteoarthritis of the knee and/or failure of the prosthesis. Limb alignment can influence both of these factors. We have examined the fate of the other compartments and measured changes in leg alignment after UKR. A total of 50 UKRs was carried out on 45 carefully selected patients between 1989 and 1992. At operat...

The article focuses on the issue of highlighting approaches being tested in contemporary migration studies to demonstrate their limits – conceptual, methodological, and methodical as analytical tools. three most popular research perspectives, namely positivism, relativism, critical realism, are taken a basis. author substantiates idea that approach accumulates much broader context than just ins...

Background To determine unicompartmental (UKR) and total knee replacement (TKR) revision rates, compare UKR rates with what they would have been had received TKR instead, assess subsequent re-revision 90-day mortality rates. Methods Using National Joint Registry data, we estimated Flexible parametric survival modeling (FPM) was used to model failure in make estimates for UKR. Kaplan-Meier were ...

We explore generic mechanisms to introduce structural hints into the method of Unsupervised Kernel Regression (UKR) in order to learn representations of data sequences in a semi-supervised way. These new extensions are targeted at representing a dextrous manipulation task. We thus evaluate the effectiveness of the proposed mechanisms on appropriate toy data that mimic the characteristics of the...

The Oxford Unicompartmental Knee replacement (UKR) was introduced as a design to reduce polyethylene wear. There has been one previous retrieval study involving this implant, which reported very low rates of wear in some specimens but abnormal patterns of wear in others. There has been no further investigation of these abnormal patterns. The bearings were retrieved from 47 patients who had rece...

The Nadaraya–Watson estimator, also known as kernel regression, is a density-based regression technique. It weights output values with the relative densities in input space. The density is measured with kernel functions that depend on bandwidth parameters. In this work we present an evolutionary bandwidth optimizer for kernel regression. The approach is based on a robust loss function, leave-on...

This paper presents an analysis of core sampling and the effectiveness using BOSHP-100.02 ball hanger. The article compared summarized used suspensions that are in UKR-185/100 analyzed economic aspects further use this equipment production. tasks increasing efficiency suspension were analyzed. A comparative hangers during was carried out. Calculated benefit use.
