Total Knee Replacement (TKR) Marjorie Eidson Total Knee Replacement (TKR)

Background

Who is injured? Majorie Eidson (my grandma)

Cause of injury Osteoarthritis Repetitive use Has fallen several times History of: Scoliosis Kyphosis Osteopenia osteoporosis

Quality of Life (before surgery) Left knee made “cracking” sound Balance is way off Easily falls over Significant pain Needed a walker to get around her own home

Case Study

Injury Severe progressive osteoarthritis in left knee has lead to significant pain, immobility, and imbalance for over five years June 2009 -- Marjorie fell due to instability of right knee -- fractured C1 and C2 vertebras. Needed head and neck immobilization (halo) for twelve weeks.

Injury, cont. The immobilization (halo) caused increased instability during the time the halo was worn as well as post apparatus removal. This was diagnosed with increased kyphosis. Additional falls could be fatal, so a decision was made to replace the left knee (more of an issue than the right).

Subluxation: incomplete or partial dislocation of a joint or organ. Sub: inferior, less, under Luxation: dislocation Periosteal reaction: formation of new bone in response to injury. Pseudogout: joint disease that causes attacks of arthritis. Pseudo: false Gout: disease created by elevated levels of uric acid in bloodstream causes crystalization of uric acid to be deposited in tendons and joints in foot.

Current Status Today Marjorie is doing great. She had three weeks of daily physical therapy, and she is now doing physical therapy three times a week for eight more weeks. She has increased mobility and is pain free in her left knee.

Knee replacement surgery has become more and more popular with the baby boomers aging. When someone decides to have knee replacement surgery, only 10-15% of patients have partial replacement, a majority of people prefer the entire replacement.

Other typical treatments used before surgery: Physical therapy Bracing Injections of steroids/other medications Anti-inflammatory medicines When all of these have failed, they are a candidate for joint replacement
