Long-patch Base Excision Repair01:02

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Bone Remodeling and Repair01:31

Bone Remodeling and Repair

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...

Summary

Anterolateral ligament reconstruction (ALLR) combined with anterior cruciate ligament reconstruction (ACLR) effectively reduces knee instability and lowers reoperation rates. This technique restores native anatomy, improving overall knee function and stability for patients.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanics

Background:

  • Anterior cruciate ligament reconstructions (ACLRs) aim to restore knee function but often leave residual anterolateral instability, a risk factor for graft failure.
  • Anterolateral ligament reconstruction (ALLR) augments ACLR by restoring the anterolateral complex, potentially reducing instability and improving outcomes.

Purpose of the Study:

  • To describe an anatomic ALLR technique using the iliotibial band to address residual knee instability after ACLR.
  • To evaluate the effectiveness of combined ACLR and ALLR in restoring knee stability and reducing reoperation rates.

Main Methods:

  • Preoperative assessment involves physical examination (pivot-shift test) and radiographic imaging (standard views, stress radiographs).
  • An 8-cm iliotibial band graft is harvested, with anchors placed at the native anterolateral ligament's tibial insertion and femoral origin.
  • Final fixation is performed after ACLR graft fixation.

Main Results:

  • Combined ACLR and ALLR showed a significantly lower reoperation rate (8.9%) compared to isolated ACLR (20.5%).
  • Revision ACLR with ALLR effectively reduced rotational laxity, as measured by the pivot-shift test.

Conclusions:

  • The described anatomic ALLR technique using the iliotibial band effectively restores knee rotational laxity and stability.
  • Combining ALLR with ACLR offers a promising approach to improve clinical outcomes and reduce graft failure in specific patient populations.
