Total Knee replacement or knee arthroplasty, is a surgical technique to resurface a knee impaired
\nby arthritis. Plastic and metal parts are used to cover the bony ends of the knee joint, along with
\nthe kneecap. This surgery is indicated for patients with severe arthritis or a severe knee injury.
\nNumerous types of arthritis may affect the knee joint. Osteoarthritis,which is considered most
\ncommon degenerative joint disease that affects mostly middle-aged and older adults, may cause
\nthe collapse of joint cartilage and adjacent bone in the knees. Rheumatoid arthritis, is considered
\nan autoimmune disases results in inflammation of the synovial membrane which lead to pain
\nand stiffness. Traumatic arthritis, arthritis due to injury, may cause damage to the cartilage of the
\nknee.
\nThe objective of knee replacement surgery is to resurface the parts of the knee joint that have
\nbeen damaged and to relieve knee pain that cannot be handeled by other treatments.
\nAlthough the single-radius (SR) femoral design is known to have theoretical advantages in many
\naspects, studies of clinical outcomes that compare the SR with the multiple-radius (MR) femoral
\ndesign are controversial.
\nA Meta-analysis study reporting the clinical outcomes of 2212 knee replacements using the SR
\n(n = 948) compared with the multiradius (MR; n = 1361) femoral design. Comparing SR with
\nMR, we observed the Knee Society Score for the knee (KSS-knee), KSS-function, knee flexion,
\nrange of motion, complications, isometric peak torque of knee, and survival rate.
\nThe range of motion of SR knees was lower than that of MR knees. No variances were stated in
\nthe analyses of KSS-knee, KSS-function, knee flexion, complications, isometric peak torque of
\nthe knee, and survival rate.
\nThis meta-analysis does not provide clinical support for the earlier stated theoretical advantages
\nof the SR implant design.
