New Ways to New Knees
New knee-replacement technologies may be limited to select patients, and clear advantages are largely unknown.
More people are undergoing knee replacement surgery, yet research suggests that about 15Ė20 percent of them arenít completely happy with their new knees. To improve patient satisfaction, scientists have developed new approaches to knee replacement, from gender-specific implants and instrumentation tailored for each patient, to computer-assisted surgery. Experts hope these newer technologies will mean a better operation and more durable knee replacement. But the juryís still out as to whether thatís the case, and these new techniques may not be for everybody, a Cleveland Clinic surgeon cautions.
