Outcome Measures

Primary Outcomes (1)

  • Knee Society Score (KSS)

    Pre-and post-operative function and patient and mechanical assessment. The KSS contains questions in 2 sections: knee joint (pain, range of motion, stability) and function (walking distance, ability to climb stairs). The greater score correlates to better outcome.

    Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

Secondary Outcomes (4)

  • Visual Analog Scale (VAS)

    Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

  • SF-36

    Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

  • Western Ontario and McMaster Universities Arthritis Index (WOMAC)

    Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

  • Radiographic assessment

    Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

Study Arms (1)

PEEK Femoral

EXPERIMENTAL

Subjects with a primary diagnosis of end-stage symptomatic primary knee osteoarthritis who require a uni-lateral knee prosthesis and have been evaluated as appropriate candidates for a total knee arthroplasty by the Investigator will be invited to take part in this clinical investigation.

Device: PEEK-Optima Femoral Component

Interventions

TKA Surgery

PEEK Femoral

Eligibility Criteria

Age50 Years - 75 Years
Sexall
Healthy VolunteersYes

  • Subjects with a primary diagnosis of end-stage symptomatic primary knee osteoarthritis
  • Subjects who, in the opinion of the Investigator, are able to understand this clinical investigation, co-operate with the investigational procedures and are willing to return to the hospital for all the required post-operative follow-ups.
  • Subjects who are able to give voluntary, written informed consent to participate in this clinical investigation and from whom consent has been obtained.

You may not qualify if:

  • Subjects who, in the opinion of the Investigator, have an existing condition that would compromise their participation and follow-up in this clinical investigation.
  • Subjects who are known drug or alcohol abusers or with psychological disorders that could affect follow-up care or treatment outcomes.
  • Subjects who have participated in a clinical study with an investigational product in the last 6 months.
  • Subjects with other significant disabling problems from the muscular-skeletal system other than in the knees (i.e muscular dystrophy, polio, neuropathic joints).
  • Subjects with a BMI of 32 or above.
  • Subjects with a current or active history of malignancy, active or suspected infection, Paget's disease, renal osteodystrophy, immunologically suppressed, rheumatoid arthritis, sickle cell anemia, and systemic lupus erythematosus.
  • Subjects with a primary or secondary diagnosis of inflammatory or traumatic arthritis.
  • Subjects defined by the Investigator as ASA Grade III or IV.
  • Subjects who have a neuromuscular or neurosensory deficit.
  • Female subjects who are pregnant or lactating.
  • Subjects with an anatomical limb alignment of above 20 degrees varus or valgus.
  • Subjects with a fixed flexion deformity of over 20 degrees.
  • Subjects with recurvatum (definition: hyperextension ≥ 5 degrees).
  • Subjects who have previously undergone total or unicondylar knee arthroplasty, high tibial osteotomy, ligament reconstruction, ORIF or with previous fracture in the ipsilateral knee joint.
