Details and patient eligibility

About

The primary purpose of TKA Randomized Clinical Trial- Cemented versus Cementless Tibial Prosthesis Study will determine whether there is a significant difference in patient-reported and measured clinical outcomes (e.g. pain, function, length of recovery, and patient satisfaction) between subjects treated with a cementless tibial prosthesis (the cementless group) and those treated with cemented tibial prosthesis (the cement group) over the first two postoperative years. Radiographs will be assessed before surgery and at established post-operative intervals to determine if there are any significant differences between patients in the two groups and to assess the influence of component fixation on radiographic stability over time. Complication and revision rates will also be assessed for comparison.
