Summary
Posteromedial knee reconstruction offers improved outcomes and reduced failure rates compared to repair. Patients can expect a full recovery and return to sport within 6-9 months post-surgery.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Ligament Reconstruction
Background:
- Medial collateral ligament (MCL) injuries often result from valgus stress or rotational movements during sports.
- Treatment selection for MCL injuries depends on injury chronicity, severity, and patient-specific factors.
Purpose of the Study:
- To describe a surgical technique for posteromedial (PMC) knee reconstruction.
- To highlight the clinical outcomes and benefits of PMC reconstruction over repair.
Main Methods:
- A medial hockey stick incision was utilized for exposure.
- Gracilis and semitendinosus tendons were harvested for graft preparation.
- Graft fixation involved anchors and a tenodesis screw with the knee in 30° flexion and varus stress.
Main Results:
- Posteromedial knee reconstruction demonstrates improved clinical outcomes compared to PMC repair.
- PMC reconstruction significantly decreases the risk of surgical failure.
Conclusions:
- Isolated MCL reconstruction patients should remain non-weightbearing for 6 weeks.
- Full, painless range of motion is expected by 12 weeks post-surgery.
- Return to sport is typically anticipated between 6 and 9 months.

02:04Fixing Double-strand Breaks
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

01:20Normal Strain under Axial Loading
Normal strain under axial loading is an important concept in the field of mechanics of materials. Axial loading implies the application of a force along the axis of a material, like a column or bar. This force can either compress or stretch the material. In the context of axial loading, normal strain is the deformation experienced by the material in the direction of the loading force. It's calculated as the change in length divided by the original length of the material. This unitless ratio...
01:10Deformation in a Circular Shaft
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...
01:20Plastic Deformation in Circular Shafts
When materials are subjected to forces that surpass their yield strength, they undergo a process known as plastic deformation. This results in a permanent alteration or strain in their structure. This concept can be specifically applied to circular shafts, where the deformation leads to a change in its shape. The precise evaluation of this plastic deformation requires understanding the stress distribution within the circular shaft, which is achieved by calculating the maximum shearing stress in...
01:21Deformations in a Transverse Cross Section
When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
