In this article, a 75-year-old patient with pain in left knee and restricted range of motion following total knee arthroplasty (TKA) is presented. Serological evaluation and aspiration of knee joint suggested a fungal prosthetic joint infection. After the diagnosis was confirmed, treatment started with antifungal drugs, removing prosthesis, exhaustive debridement, and revision of TKA after efficient antifungal treatment. At one-year follow-up, she has a painless motion range of 10 to 90 degrees, and there was no recurrence of infection observed.

Purpose: The kinematic alignment (KA) technique aims to restore native joint anatomy; however, the extent to which it restores posterior femoral condylar morphology after total knee arthroplasty (TKA) remains unclear. The posterior longitudinal overhang in the femoral condyle (PLOF) has been reported to affect clinical outcomes. This study aimed to compare the PLOF after medial pivot TKA performed using KA and mechanical alignment (MA) techniques.

The dexterity of the human hand is largely due to its multiple degrees of freedom. However, coordinating the movements of the ring and little fingers independently can be challenging because of the biomechanical and neurological interdependencies between them. This research presents a cascade control system based on fuzzy logic to manage the dynamic movements of these fingers within a simulated biomechanical model of a human hand.

Background: Microprocessor knees (MPKs) support safe and confident prosthetic walking. Their cost often prohibits prescription in low- and middle-income settings like South Africa. Funding of high-end prosthetic products in South Africa is dependent on justifications that explain why the component is prescribed, and how it can improve the user`s function.

Objective: To investigate the short- and mid-term clinical efficacy of denosumab combined with 3D-printed prosthesis in the treatment of patients with giant cell tumor of the distal radius.
Methods: From January 2016 to January 2022, 20 patients with giant cell tumor of the distal radius underwent denosumab treatment combined with 3D-printed prosthetic reconstruction at our hospital. This study evaluates the short- and mid-term efficacy by analyzing clinical cases where denosumab was used preoperatively, followed by 3D-printed biological prosthesis reconstruction of the distal radius tumor segment defect.

Introduction: There is concern in the scientific community that patients implanted years ago with metal-on-metal (M-M) bearings for total hip arthroplasty (THA) may still have persistent and potentially toxic levels of chromium (Cr) and cobalt (Co). Studies suggest that blood metal levels may be elevated in both ceramic-on-metal (C-M) and M-M bearings. The objective of this study was to establish whether patients with THA and C-M bearing surfaces require the same follow-up as those with M-M THA and to evaluate the long-term survival of THAs with M-M and C-M bearing surfaces, blood Cr and Co levels and complications (especially metallosis).
