Summary
This summary is machine-generated.Knee arthrodesis successfully restored function in a severe hemophilia A patient with a deformed knee, achieving solid fusion and pain relief. This salvage procedure offers a viable option for joint preservation challenges.
Area Of Science
- Orthopedic Surgery
- Hematology
- Reconstructive Surgery
Background
- Severe hemophilia A can lead to debilitating joint deformities, such as in the knee.
- Untreated injuries in hemophilia patients may result in severe joint damage and functional impairment, potentially leading to wheelchair dependence.
Purpose Of The Study
- To report a case of successful knee arthrodesis in a young adult with severe hemophilia A and significant knee deformity.
- To evaluate the efficacy of knee arthrodesis as a salvage procedure in complex orthopedic cases.
Main Methods
- The patient underwent knee arthrodesis with factor VIII coverage.
- Postoperative management included evacuation of a hematoma and treatment with activated prothrombin complex concentrate and recombinant factor VII for inhibitor formation.
- Functional outcomes were assessed using the Lower Extremity Functional Scale and SF-36 scores.
Main Results
- Solid knee fusion and significant pain relief were achieved within six months post-surgery.
- The patient regained independent ambulation three years after the procedure.
- Marked improvements in Lower Extremity Functional Scale and SF-36 scores were observed.
Conclusions
- Knee arthrodesis is a viable salvage procedure for restoring function and quality of life in cases where joint preservation or total knee arthroplasty is not feasible.
- This approach is particularly valuable in resource-limited settings for managing severe joint deformities in patients with bleeding disorders.

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...
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...
Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...
In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...
When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.
When the member is segmented into tiny cubic elements, it is observed that the primary stress...
