Post-Market Clinical Follow Up for Total Knee Arthroplasty System Madison

MADISON Total Knee Prosthesis is intended to be used for total knee arthroplasty to reduce pain and restore joint mobility of the knee.

Clinical data for MADISON Total Knee Prosthesis available are not deemed sufficient to support performance and benefits claimed on the whole lifetime of the product.

Thus, in order to maintain compliance with the EU regulation (2017/745) related to medical devices and following ISO 14/155:2020, SERF has set up post-market clinical follow-up study (PMCF) to confirm safety and performance of Total Knee Arthroplasty system MADISON. This study is designed to cover the expected 15-years follow-up, to retrieve data according to implant feature (Posterior Stabilized or Ultra Congruent) or fixation method and to gather data related to the revision of partial knee prosthesis.

The primary objective of this study is to assess the clinical safety of MADISON total knee prostheses. The secondary objective is to evaluate the survival rates, the clinical performances and clinical benefits of MADISON total knee prosthesis.

Inclusion criteria

  • Male or female adults (≥ 18 years) covered by French social security system

  • Osteoarthritis (primary and secondary),
  • Revision of a unicompartmental knee prosthesis.
  • Patient requiring a surgery and implantation of a Madison TKA (Total Knee Arthroplasty)

Exclusion criteria

  • Progressive, acute or chronic infection, local to the operative site or systemic that may affect the prosthetic joint,
  • Any loss of musculature or serious lesions of muscles, nerves and/or blood vessels deficiency, putting the affected limb at risk,
  • Lack of bone substance or inadequate bone quality on femoral or tibial surfaces, as it might compromise the stability of the prosthesis components,

  • Patients deprived of their liberty or hospitalised without their consent
  • Patients under legal protection (e.g. guardianship)

Treatment and study plan

Primary outcomes

  1. Revision rate according to Kaplan-Meier

    Time frame: 15 years

    Assess the revision rate, whatever the cause of revision, including infection at 15 years

Secondary outcomes

  1. Survival rate according to Kaplan-Meier

    Time frame: From per operative period to 15 years

    Assess the survival rate, whatever the cause of revision, including infection at 1 year, 3 years, 5 years and 10 years follow-up

  2. Adverse events

    Time frame: From per operative period to 15 years

    List type and occurence of adverse events

  3. Functional improvement using 2011KSS score

    Time frame: From per operative period to 15 years

    2011 KSS stands for Knee Society Score Assessement of functional improvement picked up from global 2011KSS score. The functional score is composed of four subgroups and is rating from 0 to 100 (higher score means a better outcome).

  4. Patient's expectation / satisfaction using 2011KSS score

    Time frame: From per operative period to 15 years

    2011 KSS stands for Knee Society Score Evaluation of patient's expectation / satisfaction is picked up from global 2011KSS score.

    This evaluation is rating from 0 to 55 (higher score means a better outcome).

  5. Pain reduction using 2011KSS score

    Time frame: From per operative period to 15 years

    2011 KSS stands for Knee Society Score Pain reduction evaluation is picked up from the symptom score of global 2011KSS score.

    This score is rating from 0 to 25 (higher score means a better outcome).

  6. Pain Evaluation using KOOS

    Time frame: From per operative period to 15 years

    Evaluate pain using KOOS score. KOOS stands for Knee Injury and Osteoarthritis Outcome Score. The questionnaire has five separately scored subscales: Pain, Function in Daily Living (ADL), Function in Sport and Recreation, Other Symptoms, and Knee-Related Quality of Life (QOL).

    Pain evaluation is picked up from global KOOS score. Each question is assigned a score (0-4) and a normalized score is calculated for each subscale (100 indicates no symptoms and 0 indicates extreme symptoms)

  7. Functional improvement in Daily Living using KOOS

    Time frame: From per operative period to 15 years

    Evaluate Function in Daily Living (ADL) using KOOS score. KOOS stands for Knee Injury and Osteoarthritis Outcome Score. The questionnaire has five separately scored subscales: Pain, Function in Daily Living (ADL), Function in Sport and Recreation, Other Symptoms, and Knee-Related Quality of Life (QOL).

    Function in Daily Living (ADL) evaluation is picked up from global KOOS score. Each question is assigned a score (0-4) and a normalized score is calculated for each subscale (100 indicates no symptoms and 0 indicates extreme symptoms)

  8. Functional improvement in Sport and Recreation using KOOS

    Time frame: From per operative period to 15 years

    Evaluate Function in Sport and Recreation using KOOS score. KOOS stands for Knee Injury and Osteoarthritis Outcome Score. The questionnaire has five separately scored subscales: Pain, Function in Daily Living (ADL), Function in Sport and Recreation, Other Symptoms, and Knee-Related Quality of Life (QOL).

    Function in Sport and Recreation evaluation is picked up from global KOOS score.

    Each question is assigned a score (0-4) and a normalized score is calculated for each subscale (100 indicates no symptoms and 0 indicates extreme symptoms)

  9. Functional improvement Other Symptoms using KOOS

    Time frame: From per operative period to 15 years

    Evaluate Other Symptoms using KOOS score. KOOS stands for Knee Injury and Osteoarthritis Outcome Score. The questionnaire has five separately scored subscales: Pain, Function in Daily Living (ADL), Function in Sport and Recreation, Other Symptoms, and Knee-Related Quality of Life (QOL).

    Other Symptoms evaluation is picked up from global KOOS score. Each question is assigned a score (0-4) and a normalized score is calculated for each subscale (100 indicates no symptoms and 0 indicates extreme symptoms)

  10. Assessement of Knee-Related Quality of Life using KOOS

    Time frame: From per operative period to 15 years

    Evaluate Knee-Related Quality of Life (QOL) using KOOS score. KOOS stands for Knee Injury and Osteoarthritis Outcome Score. The questionnaire has five separately scored subscales: Pain, Function in Daily Living (ADL), Function in Sport and Recreation, Other Symptoms, and Knee-Related Quality of Life (QOL).

    Knee-Related Quality of Life (QOL) assessement is picked up from global KOOS score.

  11. Oblivion of prosthesis

    Time frame: From per operative period to 15 years

    Assess the degree of forgetfulness of the prosthesis using FJS-score (Forgotten Joint Score):

    FJS stands for Forgotten Joint Score. The Forgotten Joint Score assessement consists of 12 questions and is scored on a 0-100 scale. The higher is the score, the less the patient is aware of their affected joint when performing daily activities.

  12. Mobility improvement

    Time frame: From per operative period to 15 years
