A Multicenter Study to Evaluate Functional Outcome After Knee Replacement

Study Purpose

Patients will be consecutively enrolled by implant. Implant groups will be those who have undergone surgery with either a ConforMIS iTotal® CR TKA or an Off-the- Shelf (OTS) system. The patient will conduct functional testing and answer questionnaires. The results will compare the ConforMIS iTotal with an Off the Shelf Knee replacement.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers
No

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion:

  • - Clinical condition included in the approved Indications For Use for the iTotal CR - Osteoarthritis, as confirmed by the investigator's assessment of disease status at screening visit that warrants a TKR procedure.
Disease status is assessed by Clinical and Radiographic assessment - Willingness to participate in the clinical study, to give informed consent and to attend all follow-up visits - > 18 years of age Exclusion: - Subject will require a simultaneous bilateral procedure - Other lower extremity surgery within 1 year - Severe (> 15º) fixed valgus or varus deformity - Severe (> 15º) extension deficit - Severe instability due to advanced loss of osteochondral structure - Loss of bone or musculature, osteoporosis, neuromuscular or vascular compromise in the area of the joint to be operated on to an extent that the procedure is unjustified - Insufficient bone stock on the femoral or tibial surfaces - Contralateral knee replacement surgery within the past 6 months - BMI > 40 - Active malignancy (defined as a history of any invasive malignancy - except non-melanoma skin cancer), unless patient has been treated with curative intent and there have been no clinical signs or symptoms of the malignancy for at least 5 years - Poorly controlled diabetes (defined as HbA1c >7 or surgeon discretion) - Immunocompromised - Other physical disability affecting the hips, spine, or contralateral knee that limits function - Disabling chronic pain with narcotic dependence - Compromised PCL or collateral ligament - Prior history of failed implant surgery of the joint to be treated, including Unicompartmental Knee Arthroplasty (UKA), or Bicompartmental Knee Arthroplasty (BKA) - Prior history of failed high tibial osteotomy (HTO) - Participation in another clinical study which would confound results - Inability to complete the protocol in the opinion of the clinical staff due to safety or other reasons

Trial Details

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

Trial ID:
NCT02494544

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
