Title: Vanguard Clinical Results


1
Vanguard Clinical Results
2
Soft Tissue Friendly Design
  • ? Clinical experience with less invasive surgery
    techniques in total knee arthroplasty A
    comparative study.
  • Kashyap, SN Van Ommeren JW, 2008 Knee Surg
    Sports Traumatol Arthrosc, Jun16(6)544-8.
  • - Early experience suggests functional recovery
    is earlier with less invasive technique as
    compared with open access.
  • - Patients in less invasive group had better knee
    flexion (average 116º compared to 97º)
  • ? Evaluation of Complications of the Mini
    Subvastus Technique 600TKRs
  • Schroer WC 2007 J Bone Joint Surg Am
    20078976-81
  • - Vanguard - Increased flexion at 1 year (125º v
    114º)
  • - Reduction in complications from 4 in standard
    group to 1.8

Restore Function and Range of Motion
  • ? A Single TKA System with Broad Size and
    Constraint Options Improves Outcomes for Both Men
    and Women
  • Lombardi AV et al, 2009, AAOS 2009 Annual
    Meeting, February 25-28, Las Vegas, Proceedings
    p.575, Scienti Ex No. SE28
  • - 1902 primary TKR with mean follow up of 2
    months
  • - Both genders post-operative ROM improved,
    post-operative KS pain, clinical and functional
    scores
  • - Conclude a single TKA system with a wide
    variety of sizing and constraint options can
    provide consistently excellent results for both
    men and women undergoing TKA.
  • ? The Relationship Between Pre- and Post op
    Range of Motion Utilizing Three
    Cruciate-Retaining Total Knee Prostheses
  • Stormont, MD et al 2009 (TBC) Journal of
    Investigative Surgery 2009
  • - 2 years follow showed increased flexion with
    Vanguard at 6 months (113º v 106º)
  • ? The Relationship Between Pre- and
    Postoperative Range of Motion Utilizing Three
    Cruciate-Retaining Knee Prostheses 203 Patients
  • Lombardi AV 2006, Clinical Orthopaedics and
    Related Research, Number 452, pp. 117122
  • - Refined Perioperative protocols in combination
    with a less invasive, mini-arthrotomy approach
    using special instrumentation resulted in earlier
    discharge to home, higher range of motion and
    improved clinical and pain scores.
  • - 6 week flexion 111º v 105º
  • - Higher proportion of patients reached 120º by
    week 6

Outlive the Patient
  • ? Wear Analysis of GUR1050 inserts (Vanguard)
    and Hi-fax 1900
  • Clarke I, Journal of Biomedical Materials
    Research Part B Applied Biomaterials 2007
    jbm.b.30948
  • - This wear study demonstrated that GUR1050
    inserts were indistinguishable from the Hi-fax
    1900 in terms of laboratory wear performance
  • - Given the excellent clinical history of DCM
    Hi-fax 1900, the GUR1050 should be an ideal
    candidate for TKR.
  • ? A report into Functionality and Survivorship
    to date.
  • Biomet INC 2008, Data on file
  • - 376 patients, Single surgeon series
  • - 100 survivorship _at_ 3 years (excluding
    infection) CI 95
  • - 99.7 survivorship _at_ 3 years (including
    infections)
  • - 1 revision due to infection
  • ? Multi-centre Prospective Clinical Evaluation
    (2008)
  • Biomet INC 2006, Data on file
  • - 393 patients, 18 surgeons
  • - 100 survivorship _at_ 1 year (excluding
    infection) CI 95
  • - Mean survivorship 99.1 (including infection)
  • - 1 revision due to infection
