Loads on the Knee Joint Ligaments during Stair Climbing

Background. Stair climbing is often performed by people in daily life and requires considerable energy muscle effort. This task has been widely described the literature, but role of knee joint ligaments not sufficiently investigated. could be relevant for planning ligament reconstruction surgery, providing suggestions to subjects with partial injuries, identifying compensatory strategies reducing loads. Methods. A dynamic musculoskeletal model was used analyse relationship between loads forces during stair climbing. Results. The most loaded were posterior cruciate deep fibres medial collateral ligament, particularly mid-swing phase, where maximally flexed hamstring muscles contracted. anterior recruited stance phase compensate anteriorly-directed force applied tibia vasti muscles; stabilized swing phase. tibiofemoral contact force, resulting from all external internal knee, good agreement data provided literature. Conclusions. study represents a forward step knowledge climbing, which useful informed recommendations injuries.
