Parker 2001.

Methods	RCT. Unknown randomization technique. Blinding not stated.
Participants	Osteoarthrosis: 99 participants (100 knees). Average age: 66.7 years. Thirty‐three participants were lost.
Interventions	One hundred MGI total knee replacements (Zimmer, Warsaw, Indiana) were performed in 99 participants randomized to either cementless or hybrid fixation. In all of the cases, femoral fixation was a cementless porous design. Tibial fixation was randomized to either cemented or cementless, and patellar fixation paralleled the tibial component.
Outcomes	HSS knee score, Knee Society knee score, failure rate and reasons for failure.
Notes	Duration of follow‐up: 12 years. Differences in the outcome between the two groups were not sufficiently significant to recommend one method of fixation over another.
