[Complex multiligament knee injury associated with patellar tendon rupture].

Area of Science:

• Orthopedic Surgery
• Knee Biomechanics

Background:

• Multi-ligament knee injuries involve damage to two or more major knee ligaments, occurring in less than 0.02% of orthopedic lesions.
• Complete patellar tendon rupture is rare, with a prevalence of 2.4%, and even less frequently associated with multi-ligament knee injuries.

Observation:

• A 22-year-old male sustained a high-speed accident resulting in a Stage V Schenck multi-ligament left knee injury and complete patellar tendon rupture.
• The patient underwent single-stage surgical treatment, including ligament reconstruction, four weeks after the traumatic event.

Findings:

• Eight months post-surgery, the patient achieved a subjective functional evaluation score of 88.5 using the IKDC 2000 form.
• The patient demonstrated successful reintegration into daily activities within eight months of treatment.

Implications:

• Single-stage surgical reconstruction for complex knee injuries, including patellar tendon rupture, may be a viable management option.
• Further research with larger patient cohorts is necessary to validate the long-term efficacy and outcomes of this surgical approach.
