ABSTRACT
Knee pain is a very common complaint in routine physiatry and orthopedic practice. While bursitis is a well-known and common cause of knee pain, deep infrapatellar bursa (DIPB) involvement is relatively less common. Inflammation of DIPB occurs commonly due to either direct trauma or overuse, but other rare causes have also been reported in the literature including infection, juvenile idiopathic arthritis, gout, and juvenile ankylosing spondylitis. We report a case of chronic inflammation of DIPB caused by direct trauma and associated with patellar tendinopathy. Additionally, we describe the characteristic findings on musculoskeletal ultrasonography (MSK-USG). For ultrasound evaluation, the patient should lie supine with the knee slightly flexed. Deep infrapatellar bursitis can be seen as an anechoic fluid-filled structure immediately posterior to the distal patellar tendon and anterior to the tibial tuberosity. While MRI can confirm the diagnosis of bursitis, MSK-USG can be quick, highly sensitive, and is able to confirm the diagnosis as well as to detect dynamic changes in the patellar tendon and adjacent structures. USG can also help in the treatment by guiding corticosteroid injection into the bursa. Activity modification and eccentric exercises play an important role in the rehabilitation program in these cases.
ABSTRACT
Objective: To report the demographic and clinical characteristics of 8 patients hospitalized with COVID-19 and presenting with neuropathic pain (NeuP). Design: A prospective case series with 1-month follow-up. Settings: COVID-19-dedicated wards of a tertiary care center. Participants: We included 8 consecutive cases of laboratory-confirmed cases of COVID-19 (by reverse transcription polymerase chain reaction) who presented with NeuP during the course of their acute hospitalization (N=8). Interventions: Not applicable. Main Outcome Measures: A verbal rating scale was used to assess NeuP severity at presentation and at 1-month follow-up. The Douleur Neuropathique 4 questionnaire was used to diagnose NeuP at presentation. Results: Most patients were diagnosed as moderate to severe COVID-19 (6/8) and presented with mild to moderate NeuP (6/8). A substantial proportion of patients (4/8) displayed persistence of mild pain symptoms at 1-month follow-up. Furthermore, participants displayed a favorable response to gabapentinoids with or without antidepressants. Conclusion: NeuP is a less commonly encountered symptom of COVID-19, but its early diagnosis and prompt management are of utmost importance. More studies including a larger cohort and longer follow-up are recommended for better understanding of COVID-19-associated NeuP.
