Knee joint disorders pose a significant and growing challenge to global healthcare systems. Recent advancements in robotics, sensing technologies, and artificial intelligence have driven the development of robot-assisted therapies, reducing the physical burden on therapists and improving rehabilitation outcomes. This study presents a novel knee exoskeleton designed for safe and adaptive rehabilitation, specifically targeting bed-bound stroke patients to enable early intervention.

Since Hampé's classic developmental experiments in the mid-twentieth century, the reduced avian fibula has sparked sustained curiosity. The fibula transformed throughout dinosaur evolution from a columnar structure into its splint-like avian form, a change long thought to be of little biomechanical consequence. Here we integrated comparative three-dimensional kinematic analyses with transitional morphologies from the fossil record to refute this assumption and show that the reduced fibula serves a crucial function in enabling extreme knee long-axis rotation (LAR).

Lateral knee cysts are relatively common synovial swelling. They are commonly benign swelling due to synovial fluid herniation from the joint. They are usually asymptomatic and in most cases are so small that only magnetic resonance imaging (MRI) can confirm the diagnosis.

Article Synopsis
- Synovial chondromatosis, or Reichel syndrome, is a rare condition affecting monoarticular joints, characterized by the growth of cartilage and the formation of small calcified loose bodies within the joint.
- The condition can lead to severe joint dysfunction if untreated, commonly impacting larger joints like the knee and hip, but sometimes affecting smaller joints like those in the fingers.
- A case study of a 60-year-old woman with pain and swelling in her finger led to surgical intervention, which successfully removed the calcified loose bodies, followed by rehabilitation to restore motion.
Vastus Lateralis Transfer for Reconstruction of Hip Abduction following Superior Gluteal Nerve Injury.
Plast Reconstr Surg Glob Open

From the Department of Hand-, Plastic, Reconstructive and Burn Surgery, BG Klinik Tuebingen, University of Tuebingen, Tuebingen, Germany.
A 71-year-old man who had hip abductor insufficiency due to a chronic injury to the right superior gluteal nerve injury after lipoma resection presented to our outpatient clinic 1.5 years postoperatively with persistent pain, atrophy of the gluteus medius muscle, and Trendelenburg sign with a corresponding limp. A magnetic resonance imaging scan and neurophysiological diagnostics confirmed a chronic lesion of the superior gluteal nerve with completed reinnervation and absent pathological spontaneous activity, excluding neurosurgical options to restore hip abduction.
