    Prof Nicolaas discovers five things in joint replacement surgery research

    Prof Nicolaas C. Budhiparama dr PhD SpOT(K) FICS has been inaugurated as Honorary Professor for medical science by Universitas Airlangga (UNAIR).

    The inauguration was held on Tuesday, March 1, 2022, at the Garuda Mukti Hall, UNAIR Management Office. Prof Nicolaas has dedicated himself and his education to Indonesian orthopedic fields. He was one of Habibie Prize 2021 recipients. It was awarded for his contribution in various latest surgery techniques in the orthopedic field, including the computer navigation-based surgery.

    The doctor who was A.S.I.A (Arthroplasty Society in Asia) 2019-2021 President has also achieved MURI Records as an Indonesian scientist that served in three world orthopedic organizations.

    Prof Nicolaas finished his final thesis at Leiden University on Total Knee Arthroplasty: The Asian Perspective on Patient Outcome, Implants, and Complications. Through his research, Prof Nicolaas found room for improvement in total knee arthroplasty (TKA) procedures to improve patient satisfaction. TKA or joint replacement operation is an operative procedure mostly done in osteoarthritis (OA) final stadium. “Research is done as a means to improve TKA patient’s satisfaction both from patient factor and surgery factor,” he explained. Prof Nicolaas and team compared the population in the United States of America, Europe, and Asia. The Indonesian Orthopedic and traumatology specialist mentioned five points in his doctoral thesis.

    Knee implant unsuitable for Indonesian and Dutch Patient

    Prof Nicolaas and team found that caucasian residents have different dimensions of femur and tibia bones. Caucasian residents have a larger size compared to Asians. Increasing size range of tibialis and femoral components for anteroposterior dimension will increase optimum match percentage for Asian and Caucasian patients,” he added.

    The comparison of measures of clinical outcomes of Asian Patients with North Americans

    The Indonesia World Records Museum (MURI) recipient in the medical and sports field found that the Asian population has a range of motion (ROM) significantly worse than North Americans. “Higher pain levels in Asian population compared to North Americans are perhaps caused by cultural differences and/ or social-economic reasons,” he mentioned.

    Circumferential Patellar Denervation in decreased knee pain

    Patella cauterization results showed no differences in anterior knee pain, functional external, and compilation rate compared to non-patella cauterization in primary TKA patients. The results also did not recommend circular patella cauterization on patella for patients undergoing TKA.

    Are new discoveries always the best?

    In Prof Nicolaas’ research, there was evidence to the contrary discovery regarding whether accelerometer-based computer navigation reduces coronal field outlier number. No higher quality evidence shows attractive advantages from computer navigation technology. “We concluded that this technology is not recommended to be adopted widely,” he revealed.

    Prophylaxis Tromboemboli Vena (VTE) for Joint Arthroplasty and Knee

    Prof Nicolaas found three continents, America, Europe, and Asia have different guidelines. It was predicted that the VTE number is found higher in Caucasians. “Multimodal approach focusing in early mobilization post-operation and mechanical prophylaxis usage, other than chemoprophylaxis is very important,” he concluded.
