With medial unicompartmental osteoarthritis (OA) there is occasionally a full-thickness ulcer of the cartilage on the medial side of the lateral femoral condyle. It is not clear whether this should be considered a contraindication to unicompartmental knee replacement (UKR). The aim of this study was to determine why these ulcers occur, and whether they compromise the outcome of UKR. Case studie...

Proximal tibial valgus osteotomy is one of the treatment options for painful medial compartment osteoarthritis and varus deformity knee. The aim our study was to determine quantify how much altered symptoms from gonoarthrosis. In addition we aimed establish whether Tomofix plating system would permit early weight bearing achieve union without use bone grafts. We prospectively analysed experienc...

Background and purpose - When evaluating the outcome after total knee arthroplasty (TKA), increasing emphasis has been put on patient satisfaction and ability to perform activities of daily living. To address this, the forgotten joint score (FJS) for assessment of knee awareness has been developed. We investigated the validity and reliability of the FJS. Patients and methods - A Danish version ...

BACKGROUND The aim of this study was to compare the functional outcomes and complication rates after distal femoral replacement (DFR) performed with the modular Munich-Luebeck (MML) modular prosthesis (ESKA/Orthodynamics, Luebeck, Germany) in patients being treated for malignant disease or failed total knee arthroplasty. METHODS A retrospective review of patient charts and a functional invest...

Background Traditional total knee implants designs, usually, are not able to reproduce the physiological kinematics of the knee, leaving almost 20% of the patients, those who underwent a total knee arthroplasty (TKA), not fully satisfied. Modern inserts are nowadays designed with a fully congruent medial compartment to reproduce the normal medial pivoting biomechanics of the knee. The aim of th...

Purpose The purpose of this study was to investigate complications and radiologic and clinical outcomes of medial opening wedge high tibial osteotomy (MOWHTO) using a locking plate. Materials and Methods This study reviewed 167 patients who were treated with MOWHTO using a locking plate from May 2012 to June 2014. Patients without complications were classified into group 1 and those with comp...

Background and purpose - There are many techniques for placing the femoral component in correct rotational alignment in total knee arthroplasty (TKA), but only a few have been tested against the supposed gold standard, rotation determined by postoperative computed tomography (CT). We evaluated the accuracy and variability of a new method, the clinical rotational axis (CRA) method, and assessed ...

OBJECTIVE This study was designed to address a recurring observation in our centre that, despite a satisfactory postoperative radiographic limb alignment, some patients are dissatisfied with the alignment and appearance of their operated leg. We carried out a prospective survey to determine patient perception of limb alignment after total knee arthroplasty (TKA) and whether level of satisfactio...

OBJECTIVE To determine the influence of Ontario Workplace Safety and Insurance Board (WSIB) benefits on short-term clinical outcomes of primary unilateral total knee arthroplasty (TKA). METHODS In a retrospective matched-cohort study at a single tertiary-care arthroplasty centre in Ontario, we compared a study cohort of 38 successive primary TKA patients receiving WSIB benefits from 1998 to 2...

Objectives The objective of the study was to create an interpretive categorical classification for transition in Oxford Knee Score (OKS) change score (?OKS) using anchor-based method. Study Design and Setting Registry data from 46,094 total knee replacements year 2014/15, were accessed via Health Social Care Information Center official website. Data included preoperative 6-month follow-up OKS r...
