Summary
Acute correction with focal dome osteotomy effectively corrects knee deformities. However, combining this with limb lengthening increases complication risks, making it unsuitable for such cases.
Area of Science:
- Orthopedic surgery
- Biomechanical engineering
Background:
- Knee joint deformities can lead to or worsen osteoarthritis.
- Accurate deformity correction is crucial to prevent secondary issues.
Purpose of the Study:
- To evaluate the efficacy of acute correction with focal dome osteotomy for knee deformities.
- To assess the outcomes and complications associated with this technique, particularly when combined with limb lengthening.
Main Methods:
- Focal dome osteotomy was used for acute correction in 21 knee segments (15 patients).
- Five segments also underwent postoperative limb lengthening.
Main Results:
- A mean correction angle of 16.0 degrees was achieved.
- All segments were successfully corrected.
- Limb lengthening cases had a high external fixation index (70.9 days/cm) and eight complications, mostly related to lengthening.
Conclusions:
- Acute correction with focal dome osteotomy is effective for knee alignment correction.
- This technique is not recommended for cases requiring concurrent limb lengthening due to a high complication rate, likely due to poor callus formation.

01:23Knee Joint
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 group...

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:27Fractures: 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...
