Chondromalacia patellae also known as Anterior Knee Pain, is a condition that causes the cartilage on the back of the kneecap to soften and break down. The cartilage softens and then tears, fissures, and erodes, causing the kneecap to rub against the thigh bone, which can lead to swelling and pain. 

Objectives: The objective of the study was to determine the level of vitamin D and its correlation in pregnant females presented with Chondromalacia patellae (anterior knee pain).

Materials and methods: A cross-sectional study design carried out on 300 pregnant females either in their first trimester or second trimester presented in the Orthopeadic Department OPD of Aziz Bhatti Shaheed Teaching Hospital, Gujrat in collaboration with Pathology department of Nawaz Sharif Medical College Gujrat from March 2023 to Nov 2023.
