ClinicalTrials.gov Identifier:
NCT00957723
First received: August 10, 2009

Last verified: August 2011
  Purpose

The purpose of this study is to evaluate the clinical outcomes (range of motion, pain, function, radiographic stability, and health related quality of life) of patients receiving the Triathlon Cruciate Retaining (CR) Total Knee System. These outcomes will be evaluated using pre-operative scores comparing them to post-operative scores in addition to being compared with a control group. The control group is Scorpio CR.

Further study details as provided by Stryker Orthopaedics:

Primary Outcome Measures:
  • To compare the active range of motion (ROM) values for subjects receiving the Triathlon CR Total Knee System with those of the a control group. [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To compare health related quality of life (QOL), radiographic stability, and complications when compared with subject's pre-operative status as well as with the control group, where available. [ Time Frame: 2 years and 5 years ] [ Designated as safety issue: No ]

Enrollment: 500
Study Start Date: February 2005
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Triathlon (CR) Total Knee System
    The purpose is to evaluate the Triathlon CR Total Knee System.
Detailed Description:

The Triathlon Cruciate Retaining (CR) Total Knee System components are for cemented use in total knee arthroplasty for painful, disabling joint disease of the knee resulting from non-inflammatory degenerative joint disease (including osteoarthritis, traumatic arthritis or avascular necrosis) or rheumatoid arthritis (excluded from this study according to protocol). The components are designed to improve range of motion (ROM) and stability. The Triathlon Cruciate Retaining (CR) Total Knee System is also designed to provide better anatomic fit and efficiency in the operating room. This study serves to demonstrate that subjects have reduced pain, increased ROM and improved stability following implantation with the Triathlon Cruciate Retaining (CR) Total Knee System.

  Eligibility

Ages Eligible for Study:   21 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. The patient has signed the informed consent.
  2. The patient is able to comply with follow-up requirements including post-operative weight bearing restrictions and self-evaluations.
  3. The patient is a male or non-pregnant female between the ages of 21 - 80 at time of surgery.
  4. The patient requires a primary total knee replacement.
  5. The patient has a diagnosis of osteoarthritis (OA), traumatic arthritis (TA), or avascular necrosis (AVN).
  6. The patient has intact collateral ligaments.

Exclusion Criteria:

  1. The patient has inflammatory arthritis.
  2. The patient is morbidly obese, BMI > 40.
  3. The patient has a history of total or unicompartmental reconstruction of the affected joint.
  4. The patient has had a high tibial osteotomy or femoral osteotomy.
  5. The patient has obvious charcot (a neuromuscular or neurosensory deficiency, which would limit the ability to assess the performance of the device).
  6. The patient has a systemic or metabolic disorder leading to progressive bone deterioration.
  7. The patient is immunologically compromised, or receiving chronic steroids ( > 30 days).
  8. The patient's bone stock is compromised by disease or infection which cannot provide adequate support and/or fixation to the prothesis.
  9. The patient has knee fusion to the affected joint.
  10. The patient has an active or suspected latent infection in or about the knee joint.
  11. The patient is a prisoner.
