Eligibility criteria

Inclusion

18 years or older, and skeletally mature; and
Undergoing a primary TKA for one or both knees using the cemented LinkSymphoKnee knee system as part of the surgeon's standard of care.
Able to read and understand English (because patient-reported outcome questionnaires are not validated for all potential other languages).

Exclusion

80 years of age or older,
Women who are pregnant at the time of surgery,
History of joint sepsis,
Bone defect that requires grafting,
Previous history of bone disease (e.g., severe osteoporosis or osteomalacia) which in the surgeon's opinion is severe enough to compromise device fixation,
Systemic conditions affecting bone density (e.g., inflammatory arthritis or renal disease) which in the surgeon's opinion are severe enough to compromise device fixation,
A poorly functioning contralateral total knee replacement or a contralateral revision regardless of function.

What this trial measures

  • Knee Injury and Osteoarthritis Outcome Score - Joint Replacement (KOOS-JR) - change from baseline1 year postoperative

    Patient-reported outcome measure (PROM) that assesses knee health based on questions about pain, stiffness, function, and daily activities. Minimum score = 0. Maximum score = 100. Higher score means a better outcome.

  • Revision rate5 years postoperative

    Evaluates how often patients require additional surgery to remove or replace the knee arthroplasty device components.
