Knee Arthroplasty—Advancements in Techniques and Arising Complications

Dear Colleagues,

Knee arthroplasty is known as the most successful medical procedure. It is well-regarded for its cost effectiveness, pain relief, and improvement in mobility for an end-stage osteoarthritis. The aim of further advancements in techniques and prioritising certain parameters is to further improve patient satisfaction and functional outcomes. So far, despite good survival rates, up to 20% of patients remain dissatisfied after total knee arthroplasty. Promising new technologies are constantly developing with an aim to enhance surgical accuracy and use optimal alignment for patients’ individual anatomy and morphology. The literature suggests directions for future research in order to address current fears in the techniques. We believe that individualized planning and patient-specific implant positioning will yield excellent results. Hence, patient-specific instruments, custom-made implants, fast-track knee arthroplasty, navigations and robotics have been utilised to minimize surgical stress and to improve post-operative outcomes. At the same time, acute and chronic pain control after surgery and early rehabilitation care remain a query that has received unproportionally little attention. Finally, new and modern implants have been introduced for knee arthroplasty, and the criteria for unicompartmental knee surgery have been stretched in recent years.

With this Special Issue, we want to provide an update about current advancements and their contribution in knee arthroplasty techniques and fighting the complications.

The topics of interest for this Special Issue are as follows: current concepts, advancements, novelties, approaches, qualifications, and limitations in total and unicompartmental knee arthroplasty; minimally invasive surgery in knee arthroplasty; patient-specific instrumentations and customized implants; patient-specific alignment (PSA); implant positioning and limb alignment; robotic-assisted surgery; navigation technology; implant geometries and knee morphologies; and concepts for approaching complications.

I look forward to receiving your contributions.
