The use of Total Knee Arthroplasty (TKA) in treatment of chronic degenerative pathologies of the knee boasts of an experience of 50 years. During this period the collaboration between surgeons and engineers produced many developments in the design of the prosthesis. Today this procedure is safe and established even if in continuous development. The progress in technologies and the use of new materials let researches try again old-fashioned techniques from the past in order to be improved. This enthusiasm for those discovers is not always going hand to hand with scientific validation: many open questions remains Every different concept of the design tries to answer to special needs as the reach of the highest ROM, the reduction of pain and debris, articular geometry, the type of fixation, the modularity of augments and stems, the types of constraints, knee kinematic and of course costs.

The evolution and challenges of unicompartmental knee prostheses (UNIS) are addressed, highlighting their use since the 1970s as an alternative to osteotomies. Over the years, these prostheses have gained popularity, although they initially faced criticism due to higher revision rates compared to total knee arthroplasties (TKA). Multicenter studies, such as that of Heck et al.

Article Synopsis
- The study compares two techniques—Range-of-Motion (ROM) and Akagi's line—for aligning the tibial component in total knee arthroplasty (TKA) to see how differently they align the tibia.
- Results showed that the ROM technique generally led to a tibial component aligned 2.5° more externally than Akagi's line, particularly in knees with a smaller preoperative medial proximal tibial angle.
- Overall, while the techniques produced different alignment values, they didn’t significantly differ in terms of tibial rotational movement during the procedure.

Introduction: Restoration of the anterior knee compartment is increasingly studied with the development of personalized surgery. However, evaluating the patellar tracking during the surgery is still subjective and at the surgeon's discretion. This study aimed 1) to describe the assessment of the patellar tracking during robotic-assisted total knee arthroplasty (TKA), 2) to describe a new measurement technique for evaluating the evolution of this patellar tracking, and 3) to assess its reliability and repeatability.

Background: Dalbavancin is a lipoglycopeptide antibiotic with a wide spectrum of activity against Gram-positive bacteria, including MDR isolates. Its pharmacokinetic properties and administration patterns could be useful for the treatment of bone and joint infections, especially prosthetic joint infections (PJIs).
Introduction: We report the case of an 80-year-old man who experienced an acute periprosthetic joint infection of his right total knee arthroplasty (TKA).

Article Synopsis
- The study investigates how extra-articular deformities (EADs) affect knee alignment and the integrity of collateral ligaments during total knee arthroplasty (TKA), highlighting the complexity these deformities add to surgeries.
- Using advanced imaging and AI-assisted planning, researchers created 3D models to simulate various knee deformities and assess their impact on mechanical axis alignment and ligament risk.
- Results indicate that larger deformities close to the knee lead to greater alignment deviations, but careful preoperative planning can minimize ligament damage by allowing a slight residual deformity in alignment.
