Gait Kinematics After Primary Total Knee Arthroplasty (TKA) Versus Revision TKA

Assessment at Short Term of the Gait Kinematics After Primary TKA (Stryker) Versus After Revision TKA. Prospective and Controlled Study.

The functional outcomes after TKA are satisfying with a full recovery at 6 months - 1 year. Nevertheless, the revisions of TKA have often lower functional results than primary TKA with a long delay of recovery. The Stryker TKA present the same device for primary TKA and for revision.

The aim of this study is to compare the gait kinematics at 6 months after primary Stryker TKA or Revision Stryker TKA to assess if the objective outcomes are similar with this device.

Inclusion Criteria:

• Primary TKA group: symptomatic femorotibial osteoarthritis, with an indication of primary TKA (as Triathlon Stryker)
• Revision group: first TKA removal in 1 step for mechanical failure, by a revision TKA (as Triathlon Stryker)

Exclusion Criteria:

• Septic failure
• Second or more failure in the revision group
• Associated surgical procedure as osteotomy, allograft…
• Not full weight bearing postoperatively
• Refusal to participate
