Abstract
Background: The most common condition is patellofemoral pain syndrome (PFPS), mostly prevalent in young adults and adolescents, and particularly those who take part in sport. Muscle tightness or muscle shortness is regularly an objective symptom in patients with PFPS. PFPS is an overburden injury defined by sore pain in the peripatellar area that is exaggerated by physical activities such as climbing stairs, jumping, squatting, and running or by sitting with flexed knees for a longer period. The PFPS symptoms are typically gradual, having anterior knee pain as a major symptom around the patella.
OBJECTIVE: To determine the impact of hamstring length on lower limb mobility on patients suffering from patellofemoral pain syndrome at tertiary care hospitals, Peshawar.
METHODS: A cross-sectional study was conducted in Peshawar, Khyber Pakhtunkhwa. A purposive sampling technique was used. A consent form and standard knee injury and osteoarthritis outcome scores (KOOS) questionnaire were given to 187 patients in the tertiary care hospitals of Peshawar city. Hamstring length was evaluated using the passive knee extension method to measure popliteal angle.
RESULT: The data showed that patients having patellofemoral pain syndrome (PFPS) with shorter hamstring lengths in which male participants with a mean (138.11˚) and female participants with a mean (148.27˚). The right legs were most frequently affected as compared to the left legs.
CONCLUSION: This study reported that patients having patellofemoral pain syndrome had shorter hamstring muscles. It is unclear whether this is a source or effect of the condition. Further research is advised to study how hamstring length changes along with rehabilitation
