Étude pour évaluer l'innocuité et l'efficacité de REAL INTELLIGENCE™ CORI™ dans la procédure d'arthroplastie totale du genou (PTG) (CORI RCT TKA)
Une étude prospective, multicentrique et randomisée contrôlée pour évaluer l'innocuité et l'efficacité de REAL INTELLIGENCE™ CORI™ dans la procédure d'arthroplastie totale du genou (PTG)
Background:
REAL INTELLIGENCE™ CORI™ (CORI Robotics) is a computer-assisted orthopaedic surgical navigation and burring system. CORI Robotics is designed to help surgeons in planning and executing certain types of knee surgery involving bone preparation. These types of surgery are called 'unicondylar knee arthroplasty' (UKA) and 'total knee arthroplasty' (TKA).
Purpose:
This study is being carried out to demonstrate the safety and effectiveness of the CORI Robotics in TKA procedure. The data collected will be used to demonstrate the safety and effectiveness of CORI and to register CORI in China mainland. The primary objective of this study is to evaluate the use of CORI in TKA procedure in achieving post-operative leg alignment as compared to procedures using conventional manual instruments.
Research participants / locations:
80 research participants will be recruited from up to 8 sites in 3 countries globally (Australia, China Mainland, Hong Kong and New Zealand). There will be roughly 40 patients having TKA using CORI and 40 patients having TKA using conventional procedure.

La description
Inclusion Criteria:
-
Subject is a suitable candidate for a TKA procedure using CORI and a corresponding S+N Knee Implant System.
-
Subject requires a cemented TKA as a primary indication that meets any of the following condition:
- Non-inflammatory degenerative joint disease, including osteoarthritis
- Rheumatoid arthritis
- Avascular necrosis
- Requires correction of functional deformity
- Requires treatment of fractures that were unmanageable using other techniques
-
Subject is of legal age to consent and considered skeletally mature (≥ 18 years of age at the time of surgery)
-
Subject agrees to consent to and to follow the study visit schedule (as defined in the study protocol and informed consent form), by signing the Ethical Committee (EC) or Institutional Review Board (IRB) approved informed consent form.
-
Subject plans to be available through two (2) year postoperative follow-up.
-
Applicable routine radiographic assessment is possible.
Exclusion Criteria:
- Subject requires a TKA on the index joint as a revision for a previously failed surgery, or has the need for complex implants, or any other implant than a standard TKA (e.g. stems, augments, or custom-made devices).
- Subject has been diagnosed with post-traumatic arthritis.
- Subject receives simultaneous bilateral UKA OR a unilateral UKA with contralateral TKA.
- Subject has one or more of the following arthroplasties that are not fully healed and well-functioning, as determined by the investigator:-Contralateral primary TKA or UKA, however, the subject can only have one knee enrolled in this study.
- Subject does not understand the language used in the Informed Consent Form.
- Subject does not meet the indication or is contraindicated for TKA according to the specific Smith+Nephew Knee System's Instructions For Use (IFU).
- Subject has active infection or sepsis (treated or untreated).
- Subject is morbidly obese with a body mass index (BMI) greater than 40.
- Subject is pregnant or breast feeding at the time of surgery.
- Subject, in the opinion of the Investigator, has advanced osteoarthritis or joint disease at the time of surgery and was better suited for an alternate procedure.
- Subject currently enrolled in another orthopedic clinical trial study.
- Subject has a condition(s) that may interfere with the TKA survival or outcome (i.e., Paget's or Charcot's disease, vascular insufficiency, muscular atrophy, uncontrolled diabetes, moderate to severe renal insufficiency or neuromuscular disease, or an active, local infection).
- Subject in the opinion of the Investigator has an emotional or neurological condition that would pre-empt their ability or willingness to participate in the study including mental illness, intellectual disability, drug or alcohol abuse.
- Subject, in the opinion of the Investigator, has a neuromuscular disorder that prohibited control of the index joint.
- Subject is a prisoner or meets the definition of a Vulnerable Subject per International Organization for Standardization (ISO) 14155:2020 Section 3.55.

Délai |

Post-operative Leg Alignment
Délai: 6 weeks
|
Post-operative leg alignment via radiographic assessment. Post-operative leg alignment is achieved when the deviation from the subject specific target does not exceed ±3 degrees. |
6 weeks

Component Alignment
Délai: 6 weeks
|
Component alignment will be assessed on long leg standing antero-posterior (A/P) X-rays and standard non weight bearing lateral X-rays taken 6 weeks after surgery |
6 weeks
|
|
Radiographic Assessment
Délai: 12 months and 24 months
|
Radiographic assessment on antero-posterior (A/P) and lateral (L) views shall be performed to identify the presence of radiolucent lines, osteolysis & implant migration. |

2011 Knee Society Score (KSS)
Délai: Pre-op, 6 weeks, 6 months, 12 months and 24 months
|
The Functional Knee Score is derived from assessments of walking and standing, standard activities, advanced activities, and discretionary activities in TKA subjects. The 2011 Knee Society Score consists of 4 separate subscales:
A higher number is a better outcome. |
Pre-op, 6 weeks, 6 months, 12 months and 24 months
|
|
Oxford Knee Score (OKS)
Délai: Pre-op, 6 weeks, 6 months, 12 months and 24 months
|
To specifically assess the patient's perspective of outcome following knee arthroplasty surgery in TKA subjects. Responses to each question ranges from 0-4 with a range of a possible overall score from 0-48. A score of 0 is the worst possible outcome while a score of 48 is the best possible outcome. |
Pre-op, 6 weeks, 6 months, 12 months and 24 months
|
|
Forgotten Joint Score (FJS)
Délai: 6 weeks, 6 months, 12 months and 24 months
|
To assess joint-specific patient reported outcomes in TKA subjects. Responses to 12 questions are recorded with a five point Likert response format: "Never", "almost never", "seldom", "sometimes" and "mostly". The item scores are summed and linearly transformed in a 0 to 100 scale and then reversed with a high value reflecting the ability of the subject to forget about the replaced knee joint during the activities of daily living. A score of 100 is the best possible outcome. |
6 weeks, 6 months, 12 months and 24 months
|
|
EuroQol Five-Dimensional Five-Level (EQ-5D-5L)
Délai: Pre-op, 6 weeks, 6 months, 12 months and 24 months
|
To assess the subject's health state in TKA subjects. The EQ-5D-5L is composed of the EQ-5D-5L descriptive system and the EQ Visual Analogue scale (EQ VAS). The descriptive system comprises 5 dimensions (mobility, self care, usual activities, pain/discomfort, anxiety/depression). Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Responses are coded as single-digit numbers expressing the severity level selected in each dimension. For instance, 'slight problems' (e.g. 'I have slight problems in walking about') is always coded as '2'. The digits for the five dimensions are combined in a 5-digit code. The EQ- 5D-5L index value is derived by using the vendor supplied calculator to convert each 5-digit EQ-5D-5L profile. The EQ VAS corresponds to a 20 cm vertical, visual analogue scale ranging from 'the best health you can imagine' to 'the worst health you can imagine'. A higher number is a better outcome. |
