Knee osteoarthritis is the most common joint disorder and a leading cause of ambulatory disability in adults. Conservative treatments of osteoarthritis are lacking and the most commonly prescribed mobility aid, the walking cane, is often misused and therefore fails to provide symptomatic relief. For this study, a novel walking cane with haptic biofeedback was designed to improve the partial weight-bearing techniques used for transferring bodyweight from an affected

“…7 However, MRI evaluation also has its own pitfalls, such as false-positive enhancement by fracture hematomas and small sensitivity for detecting osteochondral lesions. 12,13 The authors hypothesized that if associated knee injuries in tibial shaft fracture have no significant impact on the functional outcome of patients, their diagnosis would not be necessary. To this aim, associated knee injuries in ipsilateral tibial shaft fractures were evaluated using diagnostic arthroscopy and the impact of these injuries on the functional outcome of the patients was investigated.…”

Background:Associated injuries in tibial shaft fractures are not investigated often, and their impact on patient outcome is not clear. In this study, associated knee injuries in tibial shaft fractures were arthroscopically investigated, and their impact on the outcomes of patients were evaluated. Methods:In a prospective study, 57 patients with closed tibial shaft fractures and without concomitant fibular fractures were included. Motorvehicle accident was the most frequent mechanism of the injury. The fractures were treated with reamed and locked titanium intramedullary tibial nailing. The functional outcome was evaluated using the International Knee Documentation Committee score and compared between the patients with and without an ipsilateral associated injury. Results:The mean age of the patients was 33.2 ± 13.2 years. The mean follow-up duration was 10.2 ± 3.1 mo. In 35 patients (61.4%), at least one associated knee injury was detected. Chondral damage was the most frequent arthroscopic finding (n = 23, 40.4%). The anterior cruciate ligament (ACL) injury was the second most frequent injury (n = 7, 12.3%). No intervention was performed for chondral lesions and ACL tears. Meniscal injuries were detected in three (5.3%) patients only. The mean International Knee Documentation Committee score was 95.9 ± 2.2 in patients with and 96.2 ± 2.1 in patients without an arthroscopic finding (P = 0.38). The severity of comminution was not correlated with the incidence of arthroscopic findings (r = 0.089, P = 0.45). Conclusions:Ipsilateral injuries are frequent in tibial shaft fractures. However, they do not seem to affect the functional outcome of patients, at least in short-term follow-up.

“…At the level of evaluation of the diagnostic images, interpretation depends on the knowledge and the experience of the radiologist, although physician can be assisted by automatized detection module. It is especially important during the evaluation of the musculoskeletal system where structures are very small and oriented in longitudinal fashion where error rate is potentially high [7].…”

This paper presents image processing methods for visualization and classification of medial meniscus tears. The first method uses watershed with a threshold segmentation approach. The algorithm was tested on a number of images of the knee obtained with a use of the magnetic resonance imaging technique (MR). Images of the knee were collected from healthy subjects and patients with a clinically diagnosed meniscal pathology. Then, watershed technique was compared with other popular methods of image segmentation, i.e. simple thresholding and region growing. For this purpose, the execution speed and the efficiency of the methods were analyzed. Additionally, an automatic detection of the meniscus based on MRI of the knee joint was developed. The solutions were implemented using classical image processing methods in the MATLAB environment with an application of the Image Processing Toolbox and MVtec Halcon vision libraries. The presented methods will have a practical value for the referring physicians and the diagnostic imaging specialists.
