A regiszter feltételei, szó szerint

Mind a 20 feltétel megnézéseKevesebb

Ki vehet részt

  • The patient is a male or non-pregnant female between the ages of 40-80 years
  • The patient requires a primary total knee replacement and is indicated for robotic-assisted surgery
  • Patient is deemed appropriate for a cruciate retaining knee replacement
  • The patient has a primary diagnosis of osteoarthritis (OA)
  • The patient has intact collateral ligaments
  • The patient is able to undergo CT scanning of the affected limb
  • The patient has signed the study specific, ethics-approved, Informed Consent document
  • The patient is willing and able to comply with the specified pre-operative and post-operative clinical and radiographic evaluations

Ki nem vehet részt

  • Patient has had a previous osteotomy around the knee
  • The patient is immunologically suppressed or receiving steroids in excess of normal physiological requirements
  • The patient has metal hardware present in the region of the hip, knee or ankle (as this is known to create geometrical distortion in the region of the implant)
  • The patient has a history of total, unicompartmental reconstruction or fusion of the affected joint
  • The patient has a systemic or metabolic disorder leading to progressive bone deterioration
  • Patient has a cognitive impairment, an intellectual disability or a mental illness
  • The patient is morbidly obese (BMI ≥ 40)
  • The patient has a deformity which will require the use of stems, wedges or augments in conjunction with the Triathlon Total Knee System
  • The patient has a varus/valgus deformity ≥ 15°
  • The patient has a fixed flexion deformity ≥ 15°
  • The patient has a neuromuscular or neurosensory deficiency, which would limit the ability to assess the performance of the device
  • The patient is pregnant

A vizsgálatról

Mit akar kideríteni a vizsgálat

This study is a prospective, randomized, longitudinal study of the clinical outcomes of osteoarthritis patients treated by two different alignment philosophies for total knee replacement. All patients will be treated with the same knee system, implanted using MAKO robotic-arm assisted technology.

A vizsgálat 2 csoportja

  • Alignment according to Functional Alignment philosophyMár használt kezelés, összehasonlításként

    Patients randomized to this group will undergo a TKA (total knee arthroplasty) to receive a Triathlon Total Knee System aligned according to Functional Alignment philosophy. This method of implant alignment is defined by a patient's native joint line as well as the soft tissue envelope. Triathlon Total Knee System components will be positioned relative to intra-operative soft tissue laxity assessment. A mobile application (KneeBalancer) will be used to assist surgeon decision making during the dynamic joint balancing surgical step.

  • Alignment to the patient's natural Mechanical axisMár használt kezelés, összehasonlításként

    Patients randomized to this group will undergo a TKA (total knee arthroplasty) to receive a Triathlon Total Knee System neutrally aligned to the Mechanical axis. More specifically, the femoral component and tibial component are aligned 0° to the mechanical axis of each respective limb. Femoral component rotation is fixed to the trans-epicondylar axis. Soft tissue releases are performed at the discretion of the surgeon to achieve balance and full range of motion.
