Background: The anterior knee compartment is filled by the infrapatellar fat pad (IFP) and has been emphasized as a source of anterior knee pain (AKP).
Case Presentation: A 51-year-old woman sustained a right tibial plateau and open diaphyseal fracture 2 years earlier. She remained with chronic AKP after undergoing bone fixations. Increased anterior portion of the IFP brightness and decreased adipose tissue gliding with flexion and extension compared to the unaffected side was shown on ultrasonography. An injection of 0.2% lidocaine between the patellar tendon and IFP, and into the IFP under ultrasound guidance, immediately relieved the pain. The pain kept recurring although injections were effective for a while; thus, surgery was scheduled. Scar tissue on the IFP surface was endoscopically excised and her pain dramatically reduced.
Conclusion: This is the first report in which the detection of increased brightness on ultrasound of IFP and the injections into the IFP triggered an additional surgical intervention. Ultrasound evaluation and injection may be beneficial in pain clinic patients presenting with AKP and may provide an opportunity for diagnosis.

Background Deep learning (DL) methods can improve accelerated MRI but require validation against an independent reference standard to ensure robustness and accuracy. Purpose To validate the diagnostic performance of twofold-simultaneous-multislice (SMSx2) twofold-parallel-imaging (PIx2)-accelerated DL superresolution MRI in the knee against conventional SMSx2-PIx2-accelerated MRI using arthroscopy as the reference standard. Materials and Methods Adults with painful knee conditions were prospectively enrolled from December 2021 to October 2022.

Background: The peroneal artery is known to give branches to the anterior and posterior tibial arteries. Scattered reports in the literature over the last decade failed to provide solid evidence as to the optimum strategy for below-knee targeted revascularization in limited-option patients with critical limb-treating ischemia (CLTI). We sought to determine the benefit of performing single peroneal tibial artery angioplasty revascularization compared with single non-peroneal angiosome-targeted tibial artery angioplasty revascularization for patients presented with CLTI.

Background: Patients who incur an anterior cruciate ligament (ACL) injury and undergo ACL reconstruction (ACLR) have the intention of returning to sports at their pre-injury level; however, many do not return to the pre-injury level. This study aims to investigate the common factors that hinder patients from resuming sports activities following ACLR and to assess how these barriers impact their ability to return to sports. We hypothesized that patients' psychological factors, including fear of reinjury, would significantly influence their decision to return to sport after ACL reconstruction.

Introduction: Revision quadriceps tendon repair is a challenging problem. In this four-case series, novel quadriceps tendon revision resulted in improved range of motion and durable repair for patients with recurrent rupture.
Methods: Our technique includes a combination of a running locked #5 FiberWire or 2 mm SutureTape suture placed through parallel medial, lateral, and central drill holes in the patella with running Krackow-type quadriceps tendon repair medially and laterally resulting in four strands, delivering the vastus medialis and medial quadriceps tendon to an anatomic repair at the superior pole of the patella, with 2 sutures passed centrally and 1 each passed medially and laterally and then tied.

Introduction: Total knee replacements are becoming more prevalent. There is still a lot of controversy regarding patellar resurfacing. Surgeons advocating for resurfacing state reduced risk for anterior knee pain and need for future revision surgery.
