KNEE ARTICULAR CARTILAGE LESION          KANDILNOTES

INTRODUCTION

  • Knee articular cartilage lesions are characterized by injuries to the cartilage in the knee joint

  • Articular cartilage has limited, if any, capacity to self-heal or regenerate

  • Cartilage injuries are believed to progress, resulting in degenerative arthritis of the injured joint

  • Articular cartilage lesion progression may be dependent on size, location, presence of arthritis, and/or the status of the underlying bone as well as on patient factors such as age, limb alignment, joint stability, and body mass index

CAUSES 

  • Articular cartilage lesions usually occur from a trauma such as a twisting or direct injury to the knee

SIGNS AND SYMPTOMS

  • Pain and swelling in the knee 

  • Oftentimes associated with mechanical symptoms like catching and popping

  • Pain is usually worse after activity but can also be present at rest

TREATMENT​​

  • Treatment of knee articular cartilage lesions is dependent on multiple factors including patient age, size of lesion, and whether the lesion is stable or unstable

  • There are several principal cartilage restoration procedures that have been evaluated in randomized clinical trials:

  • Microfracture

  • Osteochondral Allograft Transplant

  • Osteochondral Autograft Transfer

  • Autologous chondrocyte implantation (ACI)

  • Particulated Articular Cartilage Transplant
