简要总结

Prospective, multi-centre, non-comparative, post-market surveillance clinical study

详细描述

PRIMARY ENDPOINT:

  • The primary endpoint is to evaluate the procedural success ie successful implantation of the device in the opinion of the surgeon

SECONDARY ENDPOINTS:

The secondary endpoints are to evaluate:

  • KSS Knee scores and KSS Function scores at 6 weeks, 6, 12 and 24 months post-treatment compared to pre-treatment
  • Subject reported outcomes (SF-36, Oxford Knee Score and WOMAC) at 6 weeks, 6, 12 and 24 months post-treatment compared to pre-treatment
  • Stability of the device through radiographic analysis to assess alignment and component position at immediate post-treatment, 6 weeks, 6, 12 and 24 months post-treatment
  • Safety in terms of adverse events and device deficiencies throughout the clinical investigation including any additional knee treatments and/or surgery
  • Survivorship analysis of the device at 12 and 24 months and annually thereafter

入选标准

  • •Male and female subjects aged 50 years of age or older and less than 75 years of age (>50 and <75 years).
  • •Subjects who require a uni-lateral knee prosthesis and have been evaluated as appropriate candidates for a total knee arthroplasty by the Investigator.
  • •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.

排除标准

  • •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 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.

研究组 & 干预措施

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.

干预措施: PEEK-Optima Femoral Component (Device)

结局指标

主要结局

Knee Society Score (KSS)

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

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.

次要结局

  • 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)
  • Visual Analog Scale (VAS)(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)
