MRI of knee: high signals in STIR sequences and its relation with anterior knee pain our population.

Abstract

Objective: To evaluate the significance of high signals in STIR sequences in MRI in patients presenting with non-traumatic knee pain. Study Design: Cross-sectional study. Setting: Department of Radiology, Liaquat National Hospital, Karachi, Pakistan. Period: March 2023 to August 2023. Methods: The patients presented for MRI of knee joint for knee pain unrelated to trauma were analyzed. Data were collected through a proforma based on 9 questions that included demographic data and questions related to the cause of pain. The total calculated sample size was 86 patients Data was analyzed through SPSS. Descriptive statistics were calculated. Association was determined using chi-square test considering p-value ≤0.05 as significant. Results: Our study showed no statistical correlation between knee pain and high STIR signals seen in pre-patellar bursa with 90.9% showing high signals with pain, while 85.3% showed high signals without pain. In our study this signal was found in about 20-30% that were mostly female household help and carpet layers. Conclusion: There is no statistical correlation between knee pain and high STIR signals seen in pre-patellar bursa.
