Effects of High-Intensity Laser Therapy Combined With Exercise in Patients With Knee Osteoarthritis

The goal of this clinical trial was to determine whether high-intensity laser therapy (HILT) combined with exercise improves pain, physical function, and muscle strength in people with knee osteoarthritis. The main questions the study aimed to answer were: * Did HILT combined with exercise lower pain more than sham laser combined with exercise? * Did HILT combined with exercise improve physical function more than sham laser combined with exercise? * Did HILT combined with exercise improve knee extensor muscle strength more than sham laser combined with exercise? Researchers compared HILT plus exercise with sham laser plus exercise to determine whether HILT provided additional benefits beyond those achieved with exercise alone. Participants: * Received either HILT or sham laser treatment for four weeks. * Participated in a standardized exercise program. * Completed assessments of pain, physical function, and muscle strength before and after treatment.

Manual Arthroplasty Versus VELYS Robotic-Assisted Solution Functional Alignment Arthroplasty for Knee Osteoarthritis

The goal of this clinical trial is to learn if the VELYS Robotic-Assisted Solution (VRAS) device helps to improve outcomes from total knee replacement, when compared to regular non-robotic-assisted total knee replacement in the treatment of osteoarthritis. It will also aim to review the longer-term safety and efficiency effects of using this device. The main questions it aims to answer are: 1. Does VRAS device-assisted total knee replacement improve patient outcomes (such as their function, satisfaction, and pain) when compared to non-robotic-assisted total knee replacement? 2. Does VRAS device-assisted total knee replacement improve clinical outcomes (such as revision risk, complications, and hospital length of stay) when compared to non-robotic-assisted total knee replacement? 3. Does VRAS device-assisted total knee replacement improve functional outcomes (including biomechanical motion analysis) when compared to non-robotic-assisted total knee replacement? 4. What are the economic and efficiency effects of VRAS device-assisted total knee replacement compared to non-robotic-assisted total knee replacement? 5. What are the human factor and learning curve effects of introducing VRAS device-assisted total knee replacement into healthcare teams? 6. Are there any differences in safety and adverse event incidence between VRAS device-assisted total knee replacement and non-robotic-assisted total knee replacement? Participants will: * Be randomised to receive a total knee replacement using either regular non-robotic-assisted methods, or with the use of the VRAS device. * Be assessed pre-operatively at the clinic, and then at 6 weeks, 6 months, and 12 months following date of operation. At these appointments patients will answer questionnaires, receive an x-ray (pre-operatively, and at 6 months post-operatively), and a subgroup will be reviewed in the motion analysis laboratory (pre-operatively, and at 6 months post-operatively). * Have their longer-term outcomes including any revision operations monitored out to 10 years through national registry data linkage (no actual follow-up for patients after 12 months).
