BACKGROUND: Few studies have analyzed the outcomes of total knee arthroplasty (TKA) in patients with prior anterior cruciate ligament (ACL) reconstruction, and the reported outcomes are controversial. The purpose of this study is to assess if prior ACL reconstruction had any impact on the outcome of subsequent TKA. METHODS: A matched case-control study was conducted in patients who underwent TKA, including 37 with prior ACL reconstruction and 37 patients without ACL reconstruction...

INTRODUCTION: The etiology of the stiff knee after total knee arthroplasty (TKA) is largely unknown, although excessive scar tissue due to arthrofibrosis is an important reason for a limited range of motion (ROM) after this procedure. Persistent limited ROM after TKA results in poor patient-reported outcomes and is increasingly becoming a more prominent reason for TKA revision surgery. METHODS: A narrative review of current literature on manipulation under anesthesia (MUA) after TKA analyzing etiology and risk factors for stiffness after TKA, effectiveness of MUA and what is known about rehabilitation after MUA...

INTRODUCTION: Knee osteoarthritis (KOA) is a common, disabling and costly medical condition. The patellofemoral joint is a critical source of pain in individuals with KOA, and coexistence of patellofemoral osteoarthritis (PFOA) and tibiofemoral osteoarthritis (TFOA) is sometimes observed. The identification of subgroups with PFOA and customised interventions to correct underlying pathomechanics is beneficial for individuals with KOA. This study aims to evaluate whether a clinic-based patella mobilisation therapy (PMT) leads to significant improvement in pain, physical function and quality of life of individuals with KOA...

BACKGROUND: Powered exoskeletons are a promising approach to restore the ability to walk after spinal cord injury (SCI). However, current exoskeletons remain limited in their walking speed and ability to support tasks of daily living, such as stair climbing or overcoming ramps. Moreover, training progress for such advanced mobility tasks is rarely reported in literature. The work presented here aims to demonstrate the basic functionality of the VariLeg exoskeleton and its ability to enable people with motor complete SCI to perform mobility tasks of daily life...

BACKGROUND: The correct amount of external rotation of the femoral component during TKA is controversial because the resulting changes in biomechanical knee function associated with varying degrees of femoral component rotation are not well understood. We addressed this question using a computational model, which allowed us to isolate the biomechanical impact of geometric factors including bony shapes, location of ligament insertions, and implant size across three different knees after posterior-stabilized (PS) TKA...

BACKGROUND: Robotic-resisted treadmill walking is a form of task-specific training that has been used to improve gait function in individuals with neurological injury, such as stroke, spinal cord injury, or cerebral palsy. Traditionally, these devices use active elements (e.g., motors or actuators) to provide resistance during walking, making them bulky, expensive, and less suitable for overground or in-home rehabilitation. We recently developed a low-cost, wearable robotic brace that generates resistive torques across the knee joint using a simple magnetic brake...

BACKGROUND: Laying on of hands (LooH) is a culturally-accepted therapy in several traditions. In Brazil, "Spiritism" (third-largest religious tradition in number of followers) uses LooH with the name of "Spiritist Passe" (SP). However, there are few studies assessing SP's role in medical outcomes. The present study aims to investigate the effects of LooH, with and without a spiritual context, on pain, joint stiffness, and functional capacity of older women (≥60 years old) with knee osteoarthritis (KOA)...

Meniscal pathologies are among the most common injuries of the femorotibial joint in both human and equine patients. Pathological forces and ensuing injuries of the cranial horn of the equine medial meniscus are considered analogous to those observed in the human posterior medial horn. Biomechanical properties of human menisci are site- and depth- specific. However, the influence of equine meniscus topography and composition on its biomechanical properties is yet unknown. A better understanding of equine meniscus composition and biomechanics could advance not only veterinary therapies for meniscus degeneration or injuries, but also further substantiate the horse as suitable translational animal model for (human) meniscus tissue engineering...

Normal knee range of motion varies slightly between individuals and measures approximately 0° to -5° of extension to 140° of flexion. A full arc of motion is required for normal gait and knee function. Loss of normal joint range of motion may occur after a traumatic knee injury and may contribute to increased pain, lower functional outcome scores, and decreased patient satisfaction. Although multiple factors may contribute to the development of motion loss, the occurrence of intra-articular scar tissue adhesions, or post-traumatic arthrofibrosis, may limit the patient's knee motion in the early postoperative period...
