Knee Joint

3.8K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Summary
This summary is machine-generated.

Patient-specific knee replacements using ConforMIS™ G2 technology offer a tailored surgical approach. This method aims to restore natural knee function through customized implants and instruments, though long-term data is pending.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Medical Device Technology

Background:

  • Traditional knee arthroplasty may not fully restore native knee biomechanics.
  • Patient-specific instrumentation aims to improve surgical accuracy and outcomes.
  • ConforMIS™ technology utilizes preoperative imaging for personalized implant design.

Purpose of the Study:

  • To describe the rationale and surgical technique for patient-specific knee arthroplasty using ConforMIS™ G2.
  • To highlight the benefits of individualized implants and disposable instrumentation.
  • To discuss the potential for restoring near-normal knee kinematics.

Main Methods:

  • Preoperative CT scans of the lower limb are used to design patient-specific implants and instruments.
  • Disposable, patient-specific drill guides and cutting-jigs ensure accurate bone preparation.
  • The surgical technique involves cartilage removal, knee balancing, bone preparation, and component implantation.

Main Results:

  • The ConforMIS™ G2 system allows for uni-, bi-, or three-compartmental knee resurfacing.
  • Patient-specific instrumentation facilitates efficient, pre-navigated saw-cuts.
  • The technique aims for an anatomically accurate knee resurfacing, potentially restoring normal kinematics.

Conclusions:

  • Patient-specific knee arthroplasty with ConforMIS™ G2 technology shows promising early results.
  • The use of individualized implants and instruments may lead to improved functional restoration.
  • Further long-term clinical data is required to fully evaluate this novel technology.
