About

A prospective, multi-centre, non-comparative, post-market clinical follow-up study to evaluate the survivorship, safety and performance of the Freedom® Total Knee System in the treatment of approximately 450 subjects who in the surgeon's opinion require a primary total knee replacement due to severe knee joint pain and loss of mobility due to osteoarthritis, rheumatoid arthritis or post-traumatic arthritis at upto 15 centers in the United Kingdom (UK). The primary objective of this study is to obtain implant survivorship and clinical outcomes data for commercially available Freedom® Total Knee System used in total knee replacement. Subjects must meet all the study inclusion / exclusion criteria before enrolment in the study. Subjects will be requested to attend out-patients clinic for clinical follow-up (CFU) or approached for telephonic follow-up (TFU) post-operatively as mentioned below.

Clinical & Telephonic Follow-up details:

  • 6-8 weeks ± 1week (Clinical follow-up)
  • 1 year ± 1 month (Clinical follow-up)
  • 3 years ± 6 months (Clinical follow-up)
  • 5 years ± 6 month (Clinical follow-up (optional) / Telephonic follow-up)
  • 10 years± 6 month (Clinical follow-up (optional) / Telephonic follow-up)

Full description

At all the clinical/telephonic follow-up visits i.e. at 8 weeks ± 1week, 1 year ± 1 month, 3 years ± 6 months, 5 years ± 6 months and 10 years ± 6 months implant survivorship and vital signs such as weight, heart rate etc including blood pressure will be recorded. Physical examination, lab measurements (optional), Radiographic assessment, concomitant medication/surgery and AE/SAE should be recorded. Also at all clinical follow ups OKS, KSS, range of motion will be recorded. The post-operative radiographic evaluations will be conducted at 0-8 weeks ± 1 week (which is considered as standard of care), 1 year ± 1 month, 3 years ± 6 months and optionally at 5 years ± 6 months, 10 years ± 6 months and Unscheduled visits, if required. The unscheduled visit is expected in some patients based on the fact that such patients might prone to complications like surgical site infections, venous thrombotic events, acute blood loss causing anaemia, nerve injury, and pain unresponsive to oral analgesics.

  • Subjects suffering from severe knee joint pain and loss of mobility due to rheumatoid arthritis, osteoarthritis or post-traumatic 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.

Exclusion criteria

  • Subjects who are known drug or alcohol abuse or with psychological disorders that could affect follow-up care or treatment outcomes.
  • Subject with a known sensitivity to device materials.
  • 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 40 or above.
  • Subjects with a current or active history of malignancy, active or suspected infection, Paget's disease, renal osteodystrophy, immunologically suppressed or have any other significant medical illness judged by investigator to exclude from study.
  • Subject with neuromuscular or neurosensory deficiency that may limit ability of the patient to evaluate the safety and efficacy of the device.
