Anterior Knee Pain (Subscribe)  

Patellar height is associated with various clinical syndromes. We asked which of three methods was the most appropriate for measuring patellar height for different age groups in terms of applicability, validity, and reliability. We evaluated 108 children and adolescents with available MR images and lateral knee radiographs using Insall-Salvati (IS),...

Conclusion In both individuals with and without PFPS, there was fair to moderate association between the FPI and some parameters of dynamic foot function. Inconsistent findings between the PFPS and control groups indicate that pathology may play a role in the relationship between static foot posture and dynamic function. The fair...

Chondromalacia patellae is caused by softening of the cartilage of the patella. This can cause loss of smoothness of the articular cartilage on the posterior side of the patella. Chondromalacia patellae tends to affect 2 age groups: teenagers (especially girls) and those over 40

Patellofemoral syndrome (PFS) is characterized by a group of symptoms that are easily diagnosed and often respond to simple management. The common presentation is knee pain in association with positions of the knee that result in increased or misdirected mechanical forces between the kneecap and femur. Ironically, as simple as...
