Infrapatellar plica injury: Magnetic resonance imaging review of a neglected cause of anterior knee pain.

Synovial plicae are normal remnants of synovial membranes within the knee joint cavity and are usually asymptomatic. Pathological infrapatellar plica, which is mostly due to plica injury, may be a potential cause of anterior knee pain, but is often overlooked and under-reported on magnetic resonance imaging (MRI). This pictorial review illustrates the MRI findings of infrapatellar plica injury and associated knee injuries, with emphasis on its differentiation from the mimics of plica injury.

Recovering from nonspecific low back pain despair: Ultrasound-guided intervention in iliolumbar syndrome.

BACKGROUND: Iliolumbar syndrome is a frequent cause of chronic nonspecific low back pain. The cornerstone of its treatment lies upon the specific diagnosis of the iliolumbar syndrome. The ultrasound guided interventions have the potential for the specific diagnosis and treatment of the iliolumbar syndrome. OBJECTIVE: To assess the role of ultrasound-guided intervention for the diagnosis and treatment of the iliolumbar syndrome. MATERIALS AND METHODS: The study comprised of fifty-seven patients of nonspecific low back pain with the clinically suspected iliolumbar syndrome. Two-staged ultrasound-guided interventions were performed: Primary diagnostic and secondary therapeutic interventions. Favorable response after the injection of local anesthetic agent in iliolumbar ligament (defined as VAS score to ≥3) was classified as confirmed Ilio-lumbar syndrome. Clinico radiological efficacy after platelet-rich plasma (PRP) injection in confirmed iliolumbar syndrome patients was done. RESULTS: Out of 57 patients, 45 (78.95%) were diagnosed with confirmed Iliolumbar syndrome after primary diagnostic intervention. The mean value of VAS at presentation was 8.02 ± 0.72 which was decreased to 3.16 ± 1.63; P < 0.0001. All 45 patients underwent PRP injection in iliolumbar ligament and 42 patients (93.33%) showed reduction in mean VAS score from 8 ± 0.67 (at presentation) to 0.89 ± 1.23 after 6 weeks follow up; P < 0.0001. Iliolumbar ligament thickness was decreased from the day of presentation (2.66 ± 0.22) to 6 weeks after therapeutic intervention (0.91 ± 0.42); P < 0.0001. CONCLUSION: The ultrasound guided diagnostic and therapeutic intervention were found to result in a specific diagnosis and remarkable recovery in the iliolumbar syndrome group of nonspecific low back pain patients.
