入选标准

  • Patients willing to sign the Informed Consent.
  • Patients able to comply with follow-up requirements including postoperative weight bearing restrictions and self-evaluations.
  • Male and non-pregnant female patients ages 21 - 80 years of age at the time of surgery.
  • Patients requiring a primary total knee replacement.
  • Patients with a diagnosis of osteoarthritis (OA), traumatic arthritis (TA), or avascular necrosis (AVN).
  • Patients with intact collateral ligaments.

排除标准

  • Patients with inflammatory arthritis.
  • Patients that are morbidly obese, body mass index (BMI) >
  • Patients with a history of total or unicompartmental reconstruction of the affected joint.
  • 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 whose surgery will utilize computer-assisted surgical navigation (CAOS) techniques.
  • Patients whose surgery will utilize minimally invasive surgical techniques.
  • Patients that are prisoners.

结局指标

主要结局

Forgotten Joint Score (FJS)

时间窗: Change from baseline at 2 years and 5 years post-operative

The average Forgotten Joint Score (FJS) of those patients receiving the Medacta GMK Sphere® knee prosthesis will be compared with the average FJS of those receiving the Medacta GMK PS knee prosthesis. The FJS total score range is 0-100, with higher scores indicating a higher degree of "forgetting" the artificial joint, that is, a lower degree of awareness.

次要结局

  • Radiographic Analysis(Pre-operative, 6 weeks, 6 months, 1, 2, 3, 4, and 5 years post-operative)
  • Total Knee Society Score (KSS)(Pre-operative, 6 weeks, 6 months, 1, 2, 3, 4, and 5 years post-operative)
  • Lower Extremity Activity Scale (LEAS)(Pre-operative, 6 weeks, 6 months, 1, 2, 3, 4, and 5 years post-operative)
