Artificial joint replacement has made immense progress in recent decades and is now one of the most successful surgical procedures in modern orthopedics. However, development continues: New materials, improved surgical techniques, and personalized treatment approaches are shaping the future of endoprosthetics. This blog provides a comprehensive overview of the innovations and proven procedures in joint replacement in 2025, with a particular focus on hip and knee joints.

Current status of artificial joint replacement

In Germany, joint replacement surgery is one of the most frequently performed operations. Approximately 450,000 hip and knee replacements are carried out each year. In addition to the high success rate, current focus is on topics such as the longevity of the implants, faster rehabilitation, and minimally invasive procedures for artificial joint replacement.

5.3 Long-term care

Networking through digital platforms between patients and doctors.

Sensors in implants provide real-time data on prosthesis function.

Specifics of hip replacement

Artificial hip replacement is one of the most successful surgical procedures worldwide. Nevertheless, it presents particular challenges and innovative developments.

6.1 Short stem prostheses

Less bone substance is removed.

Suitable for younger, active patients.

6.2 Dual-mobility prostheses

6.3 Challenges in old age

Osteoporosis can compromise the stability of joint replacements.

Cemented implants as a solution for poor bone density.

Specifics of knee replacement

Due to the complex biomechanics of the knee joint, artificial joint replacement places special demands on materials and surgical technique.

7.1 Unicompartmental knee replacement (sliding knee replacement)

Partial replacement of only one compartment of the knee.

Preservation of healthy tissue structures around the joint replacement.

7.2 Total endoprostheses (TEP; complete joint replacement)

Complete joint replacement in cases of advanced osteoarthritis.

Use of durable materials to reduce wear and tear.

7.3 Innovative Design

Rotation platform prostheses for improved mobility.

Biological implants that mimic the body's own structures.

Risks and complications of joint replacement – ​​what patients should know

Every surgical procedure carries risks, including artificial joint replacement. However, these risks are minimized through modern techniques and improved aftercare.

8.1 Infections

Use of coated implants to reduce the risk of infection.

Improvement of operating conditions through sterilized surgical robots.

8.2 Loosening of the prosthesis

Innovations such as cementless implants with a bioactive surface promote bone ingrowth into the joint replacement.

Regular follow-up care for early detection.

8.3 Revision surgeries

The use of modular prostheses facilitates replacement in case of complications.

Robot-assisted procedures for joint replacement increase the success rate.

Outlook for 2025 – Where is endoprosthetics headed?
