Knee injuries can lead to degenerative changes and arthritis, with outcomes varying based on injury type and severity. Early repair and proper management can significantly decrease the risk of post-traumatic knee osteoarthritis.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Biomechanical Engineering

Background:

  • Knee injuries are a significant cause of degenerative changes and subsequent arthritis.
  • Cartilage deterioration pathways differ based on injury type, including fractures and menisco-ligamentous injuries.
  • Post-traumatic knee osteoarthritis (OA) prevalence ranges from 15-50% after fractures and 15-20% after menisco-ligamentous injuries.

Purpose of the Study:

  • To analyze the causes and progression of post-traumatic knee osteoarthritis.
  • To evaluate the impact of different knee injuries on cartilage health and joint mechanics.
  • To discuss current and potential treatment strategies for post-traumatic knee OA.

Main Methods:

  • Review of literature on knee injuries and their long-term sequelae.

  • Analysis of factors contributing to cartilage deterioration after fractures and menisco-ligamentous injuries.
  • Evaluation of treatment outcomes, including osteotomy and prosthetic interventions.

    • Main Results:

    • Fracture-related factors like articular incongruity and malunion (especially varus deformities) significantly increase OA risk.
    • Menisco-ligamentous injuries disrupt knee kinematics, overloading the medial femoro-tibial compartment, particularly after meniscus resection and in genu varum.
    • Early anterior cruciate ligamentous repair and meniscal preservation techniques show promise in reducing OA development.

    Conclusions:

    • Post-traumatic knee OA is a common sequela influenced by injury characteristics and biomechanical factors.
    • Osteotomy to rebalance frontal femoro-tibial stress is a primary treatment for established OA.
    • For severe, diffuse lesions, semi-contained total knee prostheses offer a treatment option.
