Relationship between Q angle and patelofemoral pain syndrome in Slovenian recreational runners
Introduction: Patelofemoral Pain Syndrome (PFPS) is one of the most common overuse syndromes of knee in adults. Risk factors for PFPS are peripatellar synovitis, damage to the soft tissue structures (eg, lateral retinaculum), infrapatellar fat pad. The evidence that increased angle-Q could influence PFPS prevalence is conflicting. Methods: a cross sectional study was conducted on a random sample of 44 Slovenian recreational runners In order to investigate the relationship between the Q angle and the PFBS. The q-angle was evaluated by means of a universal goniometer according to protocol. We investigated a relationsh between increased angle-Q and the incidence of PFPS. Results: The results show that 50.0% of recreational runners with normal angle-Q on right leg pain at the front of the knee and 50.0% runners with elevated angle-Q on right leg pain at the front of their knees and have 35, 7% of runners with normal left QA-leg pain on the front of the knee and 64.3% of runners with an elevated left QA-Q on the front of the knee. Conclusions: Based on the statistical analysis of the results, we can conclude that the existing sample has a partial correlation between the angle-Q size and the incidence of PFBS. In order to confirm or to ascertain the relationship of the q-angle with PFBS, further clinical research is needed on a larger sample of Slovenian recreational runners.
