Authors' objectives: Is active or semi-active robotic arm-assisted total (rTKA) or unicompartmental (rUKA) knee arthroplasty for patients in need of surgery better than manual total (mTKA) or unicompartmental (mUKA) knee arthroplasty regarding mortality, function, revision, complications, implant positioning, health-related quality of life, pain, length of stay, operation time, learning curve, and patient experiences?
Authors' results and conclusions: This HTA report shows that although both rTKA and rUKA probably improve implant positioning, no long-term patient benefits could be identified concerning the patient-related outcomes knee function and health-related quality of life, for any robotic arm-assisted technique in comparison to manual knee arthroplasty. However, intermediate-term revision rate may be lower with semi-active rTKA than with mTKA and short-term revision rate may be lower after rUKA than after mUKA. Knee function within one year is probably improved after rUKA compared with mUKA, but not after rTKA compared with mTKA.
