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
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)
