Knee Joint

2.7K
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.

Early single-stage surgery for multiligament knee injuries, combined with prompt motion, enhances patient outcomes. This approach involves anatomic reconstructions and repairs, followed by early physical therapy for improved recovery.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Knee Biomechanics

Background:

  • Multiligament knee injuries necessitate comprehensive clinical and imaging evaluations.
  • Systematic reviews indicate improved patient-reported outcomes with early surgical intervention (<3 weeks) and motion.

Purpose of the Study:

  • To outline a single-stage surgical technique for multiligament knee injuries.
  • To detail the postoperative rehabilitation protocol emphasizing early motion and progressive bracing.

Main Methods:

  • Thorough physical examination including Lachman, posterior-drawer, varus, valgus, and rotational testing.
  • Diagnosis confirmation via MRI and stress radiography.
  • Single-stage surgical reconstruction involving open incisions for posterolateral corner (PLC) and medial knee, followed by arthroscopic preparation for anterior cruciate ligament (ACL) and double-bundle posterior cruciate ligament (DB-PCL) tunnels, with preferential meniscal repair.

Main Results:

  • Graft tensioning and fixation sequence: DB-PCL anterolateral bundle, DB-PCL posteromedial bundle, ACL, PLC, and posteromedial corner.
  • Postoperative protocol includes immediate physical therapy with knee motion and quadriceps activation.
  • Weight-bearing restrictions and bracing protocols are specific to ACL- or PCL-based reconstructions.

Conclusions:

  • Anatomic single-stage reconstruction combined with early motion and structured rehabilitation optimizes outcomes for multiligament knee injuries.
  • Verification of graft integrity and range of motion pre-closure is critical.
  • Functional testing validates return to sports post-recovery.
