Fabella is a sesamoid bone, located within the tendon of the lateral head of the gastrocnemius muscle. It may be associated with posterolateral knee pain because of repetitive friction over the posterolateral femoral condyle. We report a case of a 64-year-old woman presenting with right posterolateral knee pain. F-NaF PET-CT demonstrated increased uptake posterior to the right knee joint localizing to a fabella. Standard examination and radiographic imaging excluded other causes for posterolateral knee pain, and the increased activity was considered to be secondary to fabella syndrome...

MicroCT imaging allows for noninvasive microstructural evaluation of mineralized bone tissue, and is essential in studies of small animal models of bone and joint diseases. Automatic segmentation and evaluation of articular surfaces is challenging. Here, we present a novel method to create knee joint surface models, for the evaluation of PTOA-related joint changes in the rat using an atlas-based diffeomorphic registration to automatically isolate bone from surrounding tissues. As validation, two independent raters manually segment datasets and the resulting segmentations were compared to our novel automatic segmentation process...

BACKGROUND AND AIMS: Pain reduction is important for rehabilitation after total knee arthroplasty. Intra- and peri-articular infiltration with local anesthetics may be an alternative to commonly used locoregional techniques. Adding pregabalin orally and s-ketamine intravenously may further reduce postoperative pain. MATERIAL AND METHODS: This prospective, randomized, double-blind, placebo-controlled study compared two methods of perioperative analgesia. Control patients received a standardized multimodal postoperative analgesic regime of paracetamol, diclofenac, and piritramide-patient-controlled analgesia, including ropivacaine knee infiltration during surgery...

A female patient with a critical soft tissue defect after elective knee replacement surgery was transferred to our department for reconstruction. As wounds were rapidly progressing, necrotizing fasciitis was initially suspected but eventually ruled out by histopathological analysis. A 50 × 15 cm defect was then reconstructed by means of a combined Parascapular and latissimus dorsi flap before, a couple days later, the patient developed tender pustules and ulcers involving the flap as well as the donor site...

CONTEXT: Modifiable and non-modifiable risk factors have been identified for sustaining a primary ACL injury, however less research is available examining risk factors for a second injury. Identifying whether bony morphological factors are different (or more exaggerated) among those that experience a secondary ACL injury is critical to understanding if non-modifiable risk factors are associated with a second injury. OBJECTIVE: To identify if bony morphology is different among those that experience a secondary ACL re-injury as compared to ACL individuals that do not...

CONTEXT: Anterior Cruciate Ligament (ACL) and Patellofemoral Joint (PFJ) injuries are a significant problem among female athletes. A number of screening tasks have been used in the literature to identify those at greatest risk of injury. To date, no study has examined the relationship in two-dimensional (2D) knee valgus between common screening tasks to determine whether individuals exhibit similar movement patterns across tasks. OBJECTIVE: to establish whether frontal plane projection angle (FPPA) during the single leg squat (SLS), single leg land (SLL) and drop jump (DJ) are related...

OBJECTIVES: Malrotation of the femoral component can result in post-operative complications in total knee arthroplasty (TKA), including patellar maltracking. Therefore, we used computational simulation to investigate the influence of femoral malrotation on contact stresses on the polyethylene (PE) insert and on the patellar button as well as on the forces on the collateral ligaments. MATERIALS AND METHODS: Validated finite element (FE) models, for internal and external malrotations from 0° to 10° with regard to the neutral position, were developed to evaluate the effect of malrotation on the femoral component in TKA...
