Outcomes of Surgical Treatment Using a Custom-made Device for Total Ankle and Talar Replacement in the Management of Severe Cases of Bone Loss or Bone Compromise: a Pilot Study.

On February 17th, 2021, the FDA officially approved the use of the first patient-specific 3D-printed talar implant for compassionate use. This is a patient-specific talar spacer designed to completely replace the talus for the treatment of talar avascular necrosis. The implant represents an alternative to other surgical procedures that allows joint preservation. Recently, at the First Clinic of the Rizzoli Orthopaedic Institute, a prosthetic device has been developed that combines the tibial and meniscal components of a FAR-type ankle prosthesis (Adler Ortho) with a total talus replacement implant. Since the device is patient-specific and implanted using custom-made cutting guides, it reduces surgical invasiveness on surrounding bone structures as well as on ligamentous and tendinous structures, thereby preserving ankle function as much as possible. The customization is based on a next-generation prosthetic model produced using additive manufacturing technology and featuring hypoallergenic properties, as it is made of a titanium alloy and treated with a nitriding process. The aim of this study is therefore to evaluate the outcomes of this prosthetic device over time.

Wrist and Carpal Arthrodeses. A 1-year Follow-up Study.

This study at the Orthopedic Department, Drammen Hospital, examines the effectiveness and safety of various arthrodesis procedures in the wrist and carpus to relieve chronic pain and restore functional stability. Arthrodesis, which fuses two or more bones to eliminate joint mobility, is considered as a last resort when conservative treatments do not produce the desired results. The study includes patients with advanced degenerative changes, rheumatoid arthritis, or extensive injuries. Patients assessed preoperatively and postoperatively through measurements of range of motion, grip strength, and pain using various tools such as PRWHE, QuickDASH, EQ-5D-5L and NRS. The checks include X-rays and CT to evaluate healing. The data is analyzed to identify trends and factors that influence positively outcome. The follow-up takes place after 8 weeks, 3 months and 1 year postoperatively, with a focus on pain relief and functional improvement. The data are compared before and after surgery to assess the effectiveness of the intervention efficiency. The study has been applied for approval by REK, but rejected because it was assessed as a quality control project, and applied for the Data Protection Commissioner (PVO). The data is anonymised and stored on secure servers, with switch keys stored separately. The patients give informed consent and are insured through Norwegian Patient Injury Compensation. The study seeks to improve patient care by increasing understanding of the long-term effects of osteoarthritis, including complications and secondary osteoarthritis. The results will contribute to better clinical decisions and treatments.

Investigation of the Clinical Efficacy of Low-dose Ionizing Radiation in the Treatment of Osteoarthritis

IMMO-LDRT02 is a prospective, placebo-controlled, double-blind, randomized trial to investigate the clinical efficacy of low dose radiation therapy (LDRT) in the treatment of arthrosis. Newly diagnosed or already existing arthroses of the fingers, wrists, shoulders, knees, ankles and feet will be enclosed. Finally, the evidence of clinical benefit from LDRT (6 x 0.5 Gy) will be compared to the placebo group (6 x 0 Gy), by determination via a visual analog scale and identification of immunological changes.

Evaluation of the Efficacy of an Intra-articular Injection of Autologous Microfat Combined With Autologous Platelet-enriched Plasma in the Treatment of Radiocarpal Osteoarthritis: a Randomized Controlled Non-inferiority Trial Versus Total Wrist Denervation (Established Standard Treatment).

This is a phase II, prospective, comparative, randomized, single-center, open-label, parallel-group therapeutic trial. It is a non-inferiority trial to establish the efficacy of intra-articular injection of autologous microfat and PRP at the wrist in patients suffering from radiocarpal osteoarthritis in reference to wrist denervation.
