Summary: This study compared the effect of transverse and longitudinal incision for tibial nail insertion on anterior knee pain, showing similar outcomes in terms of knee pain and function. Despite reducing infrapatellar nerve injury, a transverse incision did not significantly improve overall patient outcomes.

Summary: This study retrospectively evaluated the demographics and outcomes of patients with peroneal nerve injuries treated with surgical management. It was found that peroneal nerve injuries are typically associated with high-energy injuries. The results showed similar outcomes between nerve grafting and nerve transfers, with satisfactory outcomes achieved in terms of restoration of ankle dorsiflexion.

Summary: This study reviewed the treatment outcomes of 8 patients with common peroneal nerve (CPN) injury. Transfer of the soleus muscular branch of the tibial nerve to the deep fibular nerve resulted in partial restoration of motor function in the patients. Four patients showed good functional recovery after surgery and were able to walk and participate in activities.

Summary: This study aimed to analyze the tibiofemoral bone bruise patterns in multiligament knee injuries (MLKIs) and specifically their association with common peroneal nerve (CPN) injuries. The study found a strong association between grade 3 posterolateral corner (PLC) injuries and CPN injuries. Additionally, the presence of anteromedial femoral condyle bone bruising on MRI was significantly correlated with CPN injuries on physical examination.

Summary: Managing concurrent knee dislocation and common peroneal nerve injury requires multi-disciplinary coordination involving knee reconstruction, nerve decompression, and foot and ankle surgery.
Surgical techniques like the Bridle Procedure can successfully restore function, with timing of interventions and maintenance of passive range of motion being crucial.

Summary: This study provides an overview of intraneural ganglia in children, focusing on diagnostic workup and treatment, especially in cases of foot drop. Surgical decompression in children is associated with satisfactory motor recovery postoperatively. The importance of ligation and transection of the articular branch nerve to prevent recurrence of intraneural ganglia is emphasized.

Summary: This study evaluated the functional recovery and quality of life in surgically treated patients with peroneal nerve injuries. The results showed that neurolysis had advantages over nerve repair and tendon transfer procedures in terms of functional recovery and foot-drop-related quality of life. However, these advantages diminished when considering all aspects of quality of life.

Summary: Surgical intervention was found to be effective for patients suffering from IBSN painful neuroma. Postoperatively, there was significant improvement in leg pain and health-related quality of life. Factors associated with unfavorable surgical outcomes included older age, multiple prior orthopedic knee surgeries, and failed attempts to resect an IBSN neuroma.

Summary: This study evaluated the anatomical details of the articular branch of the peroneal nerve and its descent in relation to the fibular length. The descending point of the articular branch was found to be located at a mean height of 18.1 mm distal to the postero-lateral tip of the fibular head, representing 5.1% of the whole fibular length starting from the same reference point.

Summary: The study explored the potential of using tacrolimus and mesenchymal stem cells combined with a fibrin gel-based drug delivery system to enhance peripheral nerve regeneration. The results showed that the combined delivery method did not result in cytotoxic effects and could be beneficial for promoting peripheral nerve regeneration.

Summary: The management of peroneal intraneural ganglia is controversial, with decompression and ligation of the articular nerve branch being the accepted treatment. However, this may result in unsatisfactory motor deficit of foot drop. A new treatment approach involves transferring a motor nerve branch of flexor hallucis longus to a nerve branch of tibialis anterior muscle to restore dorsiflex function in patients with symptomatic peroneal intraneural ganglia.

Summary: The study investigated the combined effect of mesenchymal stem cells (MSC) and local delivery of tacrolimus (FK506) on nerve regeneration in nerve autografts and decellularized allografts. Results showed that either MSC or FK506 treatment alone improved neurite outgrowth, and their combination further enhanced neurite extension in both types of grafts.

Summary: Vascularized bone grafts have shown superior outcomes compared to nonvascularized grafts in challenging clinical situations. Pedicled grafts from the distal radius, medial femoral condyle, ribs, and fibula, as well as free grafts from the fibula and medial femoral condyle/trochlea, have demonstrated particular usefulness and versatility.

Summary: This study compared the neuromuscular control of elbow flexors in unimpaired control subjects and patients with traumatic brachial plexus injury who underwent nerve transfer surgery. The results showed significant differences in neuromuscular control and torque generation between the two groups. The control group exhibited better modulation of myoelectric activation and achieved greater variability in neuromuscular control with varying torque demand, while the nerve transfer group could not modulate their myoelectric activation effectively. Further research on improving neuromuscular control is necessary for optimizing functional outcomes in nerve injury patients.

Summary: Modulating the nerve's microenvironment using exosomes can enhance nerve regeneration. This study aimed to determine the optimal dose of purified exosome product (PEP) for maximal neurite extension. Treatment with 5% PEP resulted in the longest neurite extension and was superior to the untreated control, while treatment with higher concentrations showed no significant difference. Live cell imaging suggested that PEP migrated towards the neural regeneration site. Overall, 5% PEP was found to be the optimal concentration for nerve regeneration based on this in vitro dose-response analysis.

Summary: The study compared preoperative MRI findings with intraoperative bleeding in the proximal scaphoid. The results showed that MRI was not reliable in assessing the vascularity of the proximal fragment compared to intraoperative assessment. Future efforts should focus on developing objective measures of osseous blood flow that can be performed during surgery.
