Question : what is TKR ? is it successful?
Answer : Knee replacement, or knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve the pain and disability of osteoarthritis. It may be performed for other knee diseases such as rheumatoid arthritis and psoriatic arthritis. Knee replacement surgery can be performed as a partial or a total knee replacement.In general, the surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped to allow continued motion of the knee. The operation typically involves substantial postoperative pain, and includes vigorous physical rehabilitation. The recovery period may be 6 weeks or longer and may involve the use of mobility aids (e.g. walking frames, canes, crutches) to enable the patient's return to preoperative mobility. The surgery involves exposure of the front of the knee, with detachment of part of the quadriceps muscle (vastus medialis) from the patella. The patella is displaced to one side of the joint allowing exposure of the distal end of the femur and the proximal end of the tibia. The ends of these bones are then accurately cut to shape using cutting guides oriented to the long axis of the bones. The cartilages and the anterior cruciate ligament are removed; the posterior cruciate ligament may also be removed but the tibial and fibular collateral ligaments are preserved. Metal components are then impacted onto the bone or fixed using polymethylmethacrylate (PMMA) cement. Alternative techniques exist that affix the implant without cement. These cement-less techniques may involve osseointegration, including porous metal prostheses over 90% of patients who undergo knee replacement surgery have good results. You should have a thoughtful discussion with your doctor prior to total knee replacement surgery and make sure to have your questions answered.

Question : Can you guide me in proper posture modifications at work
Answer : Ergonomics… …is the science and practice of designing jobs and workplaces to match the capabilities and limitations of the human body. Ergonomics means “Fitting the job to the worker” What two elements are at work? Static work: musculoskeletal effort required to hold a certain position, even a comfortable one. Force : amount of tension our muscles generate To get started: Warm up & stretch before activities that are repetitive, static or prolonged Take frequent breaks from ANY sustained posture every 20-30 minutes Respect pain - positions or stop painful activity Recognize early signs of inflammatory process, & report early Proper postures while lifting weights Use the largest joints & muscles to do the job Slide objects instead of lifting them Store heavy items where you won’t have to bend or reach to lift them Use ladders to get items down from high shelves Hold objects closer to your body when lifting Understand your work and do it right way. Work towards improving your working conditions Be ergonomical at work. Reporting problem early is important
