EPRD – The Endoprostheses Register Germany presents its annual report
Every year the EPRD annual report is eagerly awaited. It was presented online on 24.10.2020 and reflects the operating year 2019. Read the most important facts about hip endoprosthetics below.
In addition to many interesting findings provided by the register, we at ARTIQO can look back on a very low failure rate for the cementless fitting of the A2® short stem in the third year of use. In combination with the ANA.NOVA® Alpha or ANA.NOVA® Hybrid cup, the A2® Short stem with a failure rate of 1.9% in the third year occupies one of the leading positions among cementless hip stem implants and especially among short stems.
“On 24.10.2020 it was time again. The EPRD report, which is becoming increasingly important for us and our industry, was published. Also this year the A2® Short Stem again takes a top position. And this despite the fact that significantly more houses with a lower implantation frequency have now discovered the stem for themselves. In combination with the ANA.NOVA Hybrid and ANA.NOVA Alpha acetabular cup, the A2® stem is one of the top performers in this segment. >em>so Joachim Geßner, Management/Sales of ARTIQO.
“At this point we would like to thank all our users, because without their excellent work this result would not be possible.”
EPRD Annual Report – Results in brief
- Continuing trend towards completely cement-free anchoring of hip endoprostheses (currently 78.4% share)
- Short stems continued to grow to currently 10.4% (6.6% in 2015).
- The use of ceramic heads has become standard (88,8%)
- increase of 36 mm heads (now in 39.3% of the restorations)
- Lowest failure rate in the first three years for cementless restorations with the A2® short stem from ARTIQO®
In addition to the evaluation of the service life of endoprosthetic knee and hip fittings, other factors such as the frequency of implantations per clinic, age, gender, general condition and now also the patient’s BMI were included in the statistical evaluation. There is a clear correlation for the following criteria:
Patient age affects the probability of failure. While the results are the same for patients up to the age of 74 years between cemented and cementless restorations, the probability of failure is also increased for cementless restorations.
factor body weight. Although the BMI has only been recorded in the EPRD since 2017, it is already very clear that the risk of a new operation increases with increasing BMI, particularly in the case of hip fittings.
A higher number of concomitant diseases of the patient also has a negative effect on the service life of the implant restoration. The probability of early implant failure is increased by more than 200% for patients with 5 or more concomitant diseases compared to patients with 1-4 concomitant diseases.
Number of operations per clinic
The frequency with which joint replacement operations are performed in a hospital influences the risk of a replacement operation in all forms of care. However, a detailed analysis of the EPRD data shows that there is a wide variation between hospitals and that a high number of cases does not always mean a lower risk for subsequent replacement surgery.
Size and material of the femoral heads
Hip endoprostheses, especially in male patients, show advantages in the early phase when using larger femoral heads (36 instead of 32 head size), which is most likely due to a lower luxation rate. With regard to the choice of material for the head and insert component, the fewest failures over time are observed with ceramic/ceramic sliding pairings, although in a significantly younger patient population.
According to the EPRD, the use of cement-free short stem prostheses continues to increase. In 2019, 10.4% of total hip endoprostheses were documented to have a short stem, in absolute numbers: In 2019, 22,275 documented fittings with a short stem prosthesis were performed. In 2015 their share was still only 6.6%. Even in the fifth year of follow-up, they still show low failure rates compared to standard sheaths (average 2.5% to 3.2% in the third year) in relation to a comparative collective of patients under 70 years of age.
A2® Short Stem from ARTIQO
We are pleased to be on the right track in terms of patient safety with the A2® Short Stem we developed in combination with the ANA.NOVA® Alpha cup or the ANA.NOVA® Hybrid cup with a value of 1.9% in the third year and see this as a confirmation of our work.
Conclusion: Cementless short stems are an excellent option for the implantation of total hip endoprostheses. This is shown by the current data of the EPRD Annual Report 2020. In the top group of all cementless fittings with a very low probability of failure is the fitting with the A2® short stem from ARTIQO in combination with the ANA.NOVA® Alpha or ANA.NOVA® Hybrid cup. This year, we now have data on documented failures for the third year. The value of 1.9 gives us the confidence to offer an excellent solution for patients for whom a short stem prosthesis is an option with the A2® Short Stem prosthesis.

EPRD Endoprosthesis Register Germany
In the purely voluntary endoprostheses register, more than 1.4 million data sets on endoprosthetic fittings for hip and knee were created by 2019. The operations are still documented today. In 2019, 450,000 endoprosthetic fittings for hip and knee were performed (unchanged from 2018), of which 315,088 were documented in the EPRD, i.e. 70% of all endoprosthetic fittings for hip or knee performed in Germany in 2019.
Thus, the EPRD is currently one of the registers with the highest annual registration figures worldwide and is one of the largest registers worldwide in terms of case numbers. As an independent national register, the EPRD aims to improve the quality of hip and knee fittings. An obligatory register is in progress.
