Multi-Center Clinical Evaluation of the ATTUNE Cementless Rotating Platform Total Knee Arthroplasty

The primary objective of this study is to examine the change from pre-operative baseline to
two year postoperative functional performance improvement for the ATTUNE primary, cementless
TKA RP system as measured with the KOOS questionnaire (KOOS-ADL sub-score). This will be
carried out for two configurations: cruciate retaining rotating platform (ATTUNE Cementless
CR RP) and posterior stabilized rotating platform (ATTUNE Cementless PS RP).

The secondary objectives of this study are:

- Evaluate change from preoperative baseline in post-operative outcomes using additional
patient reported measures at 2 years: PKIP (overall and sub-scores), KOOS (overall and
sub-scores), AKS and EQ-5D-3L.

- Evaluate change from preoperative baseline in pain and satisfaction over time as
measured using a modified VAS Pain Score (discrete numbers rather than a continual
scale) at 2yr.

- Evaluate type and frequency of Adverse Events

- Evaluate survivorship of the ATTUNE Primary Cementless TKA system for the CR RP and PS
RP configurations using Kaplan-Meier survival analysis at 2yr and 5yrs.

- Evaluate primary, cementless ATTUNE TKA fixation through zonal radiographic analysis of
the bone-implant interface at 6wk, 6mo, 1yr, and 2yr after surgery.

- Evaluate any changes in anatomic tibiofemoral, femoral component and tibial component
alignment at 2 years compared to the first postoperative radiographs.

Inclusion Criteria:

surgery, inclusive.

knee.

- Subject is currently diagnosed with radicular pain from the spine that radiates into

disorder that limits mobility due to severe stiffness and pain such as fibromyalgia or
polymyalgia.

- Subject has a significant neurological or musculoskeletal disorder(s) or disease that
may adversely affect gait or weight bearing (e.g., muscular dystrophy, multiple
