IMPACT OF STATIC PROGRESSIVE STRETCH ON RANGE OF MOTION AFTER TOTAL KNEE REPLACEMENT IN PATIENTS WITH HAEMOPHILIA.

Background: Haemophilic arthropathy is often associated with a loss of range of motion. Total knee arthroplasty is an effective treatment option for patients with end-stage haemophilic arthropathy of the knee. However, even after arthroplasty, the range of motion sometimes remains insufficient.

Patient-dependent risk factors for self-perceived leg length discrepancy after total hip arthroplasty.

Purpose: Patients with equal objective leg length discrepancy (LLD) may have different subjective perceptions of this condition. Our aim was to analyze the effects of gender, age, operated side, surgical approach, body height, body mass index (BMI) and LLD measurements on self-perceived LLD after total hip arthroplasty (THA).

Materials And Methods: Observational cohort study with minimum 5-year follow-up included 159 patients with unilateral primary THA at a single institution, who reported subjective feeling of equal or unequal leg lengths after THA.

The impact of canal flare index on leg length discrepancy after total hip arthroplasty.

Introduction: The femoral stem should protrude from femur by an appropriate vertical distance to allow leg length equalization at hip arthroplasty; this distance depends on the size/shape of medullary canal and implant. The relationship between femoral morphology and achievability of leg length restoration is currently unclear. Our aim was to examine the impact of the femoral canal flare index (CFI) on the risk of leg length discrepancy (LLD) after total hip arthroplasty with different femoral stems.

Better results with patelloplasty compared to traditional total knee arthroplasty.

Purpose: The aim of this study was to compare the results of primary total knee arthroplasty with or without patelloplasty.

Methods: We retrospectively reviewed 89 patients who had received total knee arthroplasty. In patelloplasty, the patellar cartilage was resected using a tangential saw cut, and in the traditional treatment, only the surrounding osteophytes were removed.

Momentary information transfer as a coupling measure of time series.

We propose a method to analyze couplings between two simultaneously measured time series. Our approach is based on conditional mutual sorting information. It is related to other concepts for detecting coupling directions: the old idea of Marko for directed information and the more recent concept of Schreiber's transfer entropy.
