入选标准

  • Patients willing to sign the informed consent.
  • Patients able to comply with study requirements including stress x-rays and self-evaluations.
  • Male and non-pregnant females ages 21 - 80 years of age at the time of surgery.
  • Patients who have undergone a primary total knee replacement, are one year or greater postoperative, and are not having any evidence of failure of their implants.
  • Patients with a diagnosis of osteoarthritis (OA), traumatic arthritis (TA), or avascular necrosis (AVN).
  • Patients with intact collateral ligaments.
  • Range of motion within five degrees of full extension and a minimum of 120 degrees of flexion.

排除标准

  • Patients with inflammatory arthritis.
  • Patients that are morbidly obese, body mass index (BMI) >
  • Patients that have had a high tibial osteotomy or femoral osteotomy.
  • Patients with neuromuscular or neurosensory deficiency, which would limit the ability to assess the performance of the device.
  • Patients with a systemic or metabolic disorder leading to progressive bone deterioration.
  • Patients that are immunologically compromised, or receiving chronic steroids (>30 days), excluding inhalers.
  • Patients bone stock is compromised by disease or infection, which cannot provide adequate support and/or fixation to the prosthesis.
  • Patients with knee fusion to the affected joint.
  • Patients with an active or suspected latent infection in or about the knee joint.
  • Patients that are prisoners.

结局指标

主要结局

Measurement of antero-posterior stability of the knee with stress x-rays.

时间窗: 1 year post-operative

Antero-posterior stability of the knee will be measured with stress x-rays using the TELOS Stress device in 45° and 90° flexion. Stress x-rays will be obtained during a single visit for subjects 1 year or greater post-operatively.

次要结局

  • Knee Society Score (KSS)(1 year post-operative)
  • Lower Extremity Activity Scale (LEAS)(1 year post-operative)
  • Forgotten Joint Score (FJS)(1 year post-operative)
