Coverage refers to the proportion (%) of hospitals/departments contributing to registration in the national/regional register out of the total number of hospitals/departments performing knee procedures in the country/region.
Completeness refers to the proportion (%) of knee operations registered in the register out of the total number performed in the country/region.
NAR established with registration of hip arthroplasty in 1987, but started registration of knee and other joint arthroplasties in 1994.
AJRR does not have data on coverage or completeness due to the lack of centralized healthcare and market structure. NB: Data reported from AJRR (USA) does not include that of KP (USA) data.
Registry was started in 2010 and enrolment started (November) 2012. Since 2019 national completeness is > 70 %.
JointCare established as an organization in 2012, but the registry started in 2015. There is no mandatory reporting of arthroplasties in South Africa. Coverage and completeness are best estimates. JointCare comprises a network of surgeons in private practice and coverage is restricted to primary surgeries. The JointCare captures revisions only when reported by a patient in follow-up correspondence. The operative data pertaining to the revision surgery itself is not captured.
