Stem cells enable surgeons to grow replacement cartilage, which gives the new tissue greater growth potential. [11] [12] While there are few long-term studies as of 2018, a history of knee problems [13] and body weight are factors for how well the procedure will work. [14]
Some physicians and patients may consider having ultrasonography for deep venous thrombosis after knee replacement. [75] [76] Neither gabapentin nor pregabalin have been found to be useful for pain following a knee replacement. [77] A Cochrane review concluded that early multidisciplinary rehabilitation programs may produce better results. [78]
PJIs are the most common cause of knee replacement failures, and the third most common cause of hip replacement failures. [1] As of 2017, 2.1% of hip and 2.3% of knee replacements will at some time develop a PJI. [2] The incidence of PJIs have more than tripled in the last 20 years, with the incidence expected to further increase in the future.
The goals of phase 1 rehabilitation are: control post-operative pain, reduce inflammation, provide passive motion in a specific plane of movement, and protect the healing repair or tissue. CPM is carried out by a CPM device, which constantly moves the joint through a controlled range of motion ; the exact range is dependent upon the joint, but ...
Unicompartmental knee arthroplasty (UKA) is a surgical procedure used to relieve arthritis in one of the knee compartments in which the damaged parts of the knee are replaced. UKA surgery may reduce post-operative pain and have a shorter recovery period than a total knee replacement procedure, [ 1 ] [ 2 ] particularly in people over 75 years of ...
Arthrofibrosis can occur after total knee replacement or partial knee replacement, when excessive scar tissue (collagen fibril) deposition occurs in and around the knee. This can be accompanied by shortening of the patellar tendon (patella baja/infera) which can also contribute to limited flexion.

It was defined by John Homans in 1941 as discomfort behind the knee upon forced dorsiflexion of the foot. [1] After many examples of false-positive Homans' signs were reported, Homans redefined it in 1944, stating that "discomfort need have no part in the reaction", and that increased resistance, involuntary flexure of the knee or pain in the ...
