OBJECTIVE: To determine whether jump-landing patterns, as assessed by the Landing Error Scoring System (LESS), differ based on sex and knee injury history. DESIGN: Cross-sectional. SETTING: College. PARTICIPANTS: Two hundred fifteen intercollegiate athletes were grouped by sex (male = 116 and female = 99) and self-reported knee injury history (no = 148, mild = 31, and severe = 36). INTERVENTIONS: Participants performed 3 trials of a standardized jump-landing task that were videotaped and later scored using the LESS...

The hamstring muscles were analyzed anatomically and physiologically to clarify the specific reasons for the incidence of muscle strain of the hamstrings. For the anatomical study, hamstring muscles of 13 embalmed cadavers were dissected. For the physiological study, the knee flexor torque and surface electromyographic (EMG) signals were measured during isometric contraction of hamstring muscles in 10 healthy adults. The biceps femoris muscle long head (BF-L) and semimembranosus muscle (SM) had hemi-pennate architecture and their fiber length per total muscle length (FL/TML) was smaller than that of semtendinosus muscle (ST) and biceps femoris muscle short head (BF-S) with other architecture...

Patellofemoral pain syndrome (PFPS) is the most common cause of knee pain in the outpatient setting. It is caused by imbalances in the forces controlling patellar tracking during knee flexion and extension, particularly with overloading of the joint. Risk factors include overuse, trauma, muscle dysfunction, tight lateral restraints, patellar hypermobility, and poor quadriceps flexibility. Typical symptoms include pain behind or around the patella that is increased with running and activities that involve knee flexion...
