Descriptive Information
Brief Title Zimmer CAS PSI X-Ray Knee in TKA (Total Knee Arthroplasty)
Official Title Evaluation of Zimmer® CAS PSI X-Ray Knee in Total Knee Arthroplasty (TKA): Technical Outcomes
Brief Summary The objective of the observational study is to assess the positioning of customized guides designed from patients X-Rays (Zimmer® X-Ray PSI Knee) using optical navigation in primary total knee arthroplasty.
Detailed Description The proposed research is a single center, prospective, case series, and non-controlled study. One orthopedic surgeon will perform 30 primary TKAs using X-Ray PSI Knee guides, generated from X-ray. Patients who have been appropriately indicated as candidates for TKA and who meet the specified inclusion and exclusion criteria, will be informed about Zimmer® X-Ray PSI Knee technology and offered entry into the study. Informed consent, in accordance with current ethical board regulatory requirements and best practice, will be obtained from all patients.

Eligibility Criteria

Inclusion Criteria:

  • Male or female

  • Diagnosed with non-inflammatory degenerative joint disease (e.g., osteoarthritis, post-traumatic arthritis, avascular necrosis, etc.)
  • Over 18 years old
  • Able to:
  • Understand what participation in the study entails and willing to consent (patient or his/her legal guardian) to participate in the study by signing and dating an IRB/EC approved inform consent form. and

  • Able and willing to undergo a preoperative radiographs (all cases)
  • Meets an acceptable preoperative medical clearance and is free of or treated for cardiac, pulmonary, hematological or other conditions that would pose excessive operative risk.

Exclusion Criteria:

  • Is currently enrolled in an investigational new drug or device study
  • Has an active infection (including septic knee, distant infection, or osteomyelitis)
  • Has neurological disorders (including, but not limited to Parkinson's disease)
  • Has had a prior ipsilateral unicompartmental knee arthroplasty, TKA, knee fusion or patellectomy.
  • Has hip or knee ankylosis.
  • Have indications of intra- and/or extra-articular deformations that would eliminate or tend to eliminate adequate implant support or prevent the use of an appropriately sized implant, such as polio, history of tibial plateau fracture, etc.
  • Has any metal within 150 mm of the joint line for the operative-side knee.
  • Has knee deformities greater than 15 degrees of fixed varus, valgus, or flexion contracture on initial physical examination.
