Summary
This study presents a knee disarticulation with femoral shortening osteotomy for a complex knee injury. The procedure successfully restored function, enabling daily prosthesis use and weekly running for an active-duty service member.
Area of Science:
- Orthopedic surgery
- Trauma surgery
- Amputation surgery
Background:
- Limb salvage failure in complex knee injuries presents significant challenges.
- Open Gustilo 3C knee dislocations often necessitate advanced surgical interventions.
- Previous amputation techniques at this level have faced issues with limb length discrepancy.
Purpose of the Study:
- To evaluate the efficacy of knee disarticulation combined with femoral shortening osteotomy.
- To address limb length discrepancies in patients undergoing knee disarticulation.
- To restore functional mobility and quality of life after severe knee trauma.
Main Methods:
- A case study involving a 28-year-old active-duty male with failed limb salvage.
- Procedure included an 8-cm femoral resection osteotomy and intramedullary nail stabilization.
- Follow-up assessed osseous union, functional ambulation, and prosthetic use.
Main Results:
- Successful osseous union at the osteotomy site without reoperation after 16 months.
- Patient achieved daily ambulation with a prosthesis.
- Patient was able to engage in weekly running activities.
Conclusions:
- Knee disarticulation with femoral shortening osteotomy is a viable solution for complex knee injuries.
- This technique preserves the benefits of knee disarticulation while resolving limb length issues.
- The procedure facilitates return to high-level physical activity.

01:23Knee Joint
3.2K
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...

01:24Data Reporting and Recording
5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

02:11Reporter Genes
13.2K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
