Brief Summary

Investigating the biomechanics for the PCL ruptured or reconstructed patients during walking, jogging, cutting, jumping. To establish a knee joint biomechanical evaluation model to quantify and evaluate the plantar pressure information under dynamic load-bearing state after PCL fracture. Provide a precise basis for the biomechanical state of the knee, and establish a clinically practical automatic analysis of plantar pressure information and an expert diagnostic system.

Eligibility Criteria

• Age: 18 Years - 45 Years
• Sex: all
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

Inclusion：age of 18-45 years old. Healthy volunteers: no history of neuro or musculoskeletal system injury that may affect the movements. Isolated PCL rupture patients: The inclusion criteria included an isolated PCL rupture of at least 3 months' duration. The exclusion criteria were (1) additional knee ligament or meniscal damage; (2) severe damage to the ipsilateral hip, ankle joint, or contralateral lower limb (ligament ruptures or bone fractures); (3) age \>50 years (to avoid age-induced osteoarthritis interference); (4) any cartilage injury grade \>2 according to the Outerbridge classification; and (5) Tegner score18 \<3.

You may qualify if:

• age of 18-45 years old
• Healthy volunteers: no history of neuro or musculoskeletal system injury that may affect the movements.

You may not qualify if:

• additional knee ligament or meniscal damage
• severe damage to the ipsilateral hip, ankle joint, or contralateral lower limb (ligament ruptures or bone fractures)
• age \>50 years (to avoid age-induced osteoarthritis interference)
• any cartilage injury grade \>2 according to the Outerbridge classification
• Tegner score18 \<3
