About 21% to 35% of people with limb loss are those who lost their limb at trans-femoral level (i.e. above the knee). The increasing number of diabetes-related limb loss (amputation) and the rising proportion of older adult amputees indicates more amputees with limited mobility in the future. Among other factors, prosthesis success highly depends on the function of the knee joints during daily activities.
Presently, there are two categories of prosthetic knee joints; microprocessor-controlled knees (MPKs) and non-microprocessor-controlled knees (n-MPKs). Whilst the n-MPKs are unable to change the knee stiffness, the MPKs alter the joint stiffness and speed of movement according to the users' walking speed.
Although past studies indicate that MPKs could result in reduced risk of falls, improved balance and activity in limited mobility amputees, there is a lack of strong evidence on the effect of MPKs on community outcomes. The aim of this study is to compare activity, mobility, social functioning, depression, anxiety, and health-related quality of life in limited mobility trans-femoral or through-knee (i.e. knee disarticulation) amputees who are users of MPKs prosthesis with users of a prosthesis with n-MPKs.

This study will assess if the functional performance and musculoskeletal outcome of transfemoral amputees are improved after receiving a Microprocessor Knee (MPK) compared to a Non-Micropr...
The aim of this post-market study is to confirm that the microprocessor controlled prosthetic knee components (C-Leg 3 and C-Leg 4) in comparison to mechanical knee joints can bring additi...
The central hypothesis of this proposal is that real-life benefits of microprocessor knees (MPK) are largely underappreciated because of the lack of sensitive and ecologically valid method...
The purpose of this research is to evaluate benefits of a microprocessor controlled prosthetic ankle-foot device compared to a non-microprocessor controlled or passive carbon fiber prosthe...
Osteoarthritis (OA) is one of the most common diseases affecting the joints, usually those that are weight bearing such as the knees. OA is considered to be a disease of the cartilage in t...
A prosthetic knee is the key component of the transfemoral prosthesis. The performance of the prosthetic knee determines the walking ability of transfemoral amputees.
The aim of the present study is to compare sagittal gait kinematics of ankle, knee and hip joints between subjects with unicondylar and total knee arthroplasty and age matched healthy controls. Since ...
The hip and knee joints differ biomechanically in terms of contact stresses, fluid lubrication and wear patterns. These differences may be reflected in the synovial fluid (SF) composition of the two j...
Diabetes is a multisystemic and multifaceted syndrome, and its clinical impact is wide ranging and varied. The musculoskeletal complications of diabetes, too cover a broad spectrum of joints and prese...
Joint inflammation, with consequent cartilage damage and pain, typically reduces functionality and affects activities of daily life in a variety of musculoskeletal diseases. Since mechanical loading i...
Small computers using LSI (large-scale integration) microprocessor chips as the CPU (central processing unit) and semiconductor memories for compact, inexpensive storage of program instructions and data. They are smaller and less expensive than minicomputers and are usually built into a dedicated system where they are optimized for a particular application. "Microprocessor" may refer to just the CPU or the entire microcomputer.
An instrument used to assess the results of rehabilitation from knee injuries, especially those requiring ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION. It measures recovery of knee joint function based on ACTIVITIES OF DAILY LIVING.
A type of osteochondritis in which articular cartilage and associated bone becomes partially or totally detached to form joint loose bodies. Affects mainly the knee, ankle, and elbow joints.
Injuries to the knee or the knee joint.
The physical state of supporting an applied load. This often refers to the weight-bearing bones or joints that support the body's weight, especially those in the spine, hip, knee, and foot.
A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including Arthritis - inflammation of a joint causes pain, stiffness, and swelling with ...
Arthroplasty is a surgical procedure to restore the integrity and function of a joint. A joint can be restored by resurfacing the bones. An artificial joint (called a prosthesis) may also be used. Various types of arthritis may affect the joints. Osteo...
