What is Knee angle frame?
Knee angle frames are a type of orthopaedic device used in surgeries involving the lower extremity.The lower body, in particular the knee and lower leg, is supported and stabilised by the frame. As it helps to assure adequate positioning and alignment of the nearby bones and muscles, this is a crucial tool for many orthopaedic surgeons.
Overview / Product Profile of Knee angle frame:
Knee angle frame is generally composed of ASTM standard medical grade polymers / metal / wood. Knee angle frame has base For the device to stand & two metal/ polymer / wooden bars with a hinge in middle usually adjustable in length to accommodate different knee angles and height, this two bars may have a rubber or foam cushion to provide comfort and stability.During treatments like arthroscopy, ACL reconstruction, or meniscus repair, the frames can be employed to support the knee in a number of postures. They assist patients in maintaining appropriate positioning while recovering from surgery.
Dimensions:
Length:
Length of knee angle frame ranges in size from 8 cm to 28 cm.
Width:
Width of knee angle frame ranges from 5 cm to 16 cm.
Height:
Height of knee angle frame ranges from 5 cm to 20 cm.
Note: The above dimensions may vary slightly depending on the manufacturer and specific design of the instrument. It's always advisable to consult with the manufacturer's specifications and guidance for accurate measurements.
Uses of Knee angle frame:
1) Used to keep the knee joint locked during ligament replacement and repair.
2) Employed to keep the knee joint immobile while fracture repairs are being made.
3) Applied to offer stability throughout arthroscopic procedures.
4) Applied to offer stability throughout arthroplasty surgeries.
5) Used to offer stability while meniscus repairs are being done.
6) Employed to offer stability during tendon transplants and repairs.
7) Employed as a stabilising agent during chondroplasty treatments.
8) Helps maintain stability throughout osteotomy treatments.
9) Applied to offer stability for joint debridement operations.
10) Applied to offer stability throughout lavage treatments.
Precautions with Knee angle frame:
1) If possible, use the proper straps and safety locks to securing the patient's legs in the knee angle frame.
2) Prior to the surgery, make sure the patient is lying down comfortably in the frame.
3) Ascertain that the patient's legs are securely braced and are situated comfortably.
4) Throughout the procedure, keep an eye on the patient's vital signs.
5) To sustain communication, keep a clear line of sight between the patient and the surgeon.
6) During the procedure, check sure the frame is stable and is not shifting.
7) When not in use, make sure the frame is locked in the proper position.
8) Ensure that the patient's legs are protected from pressure injuries by using all necessary padding.
9) Look for any evidence of deterioration in the frame.
10) Position the knee angle frame away from any other medical supplies or staff.
History of Knee angle frame:
Since the early 1980s, knee angle frames (also known as KAFs) have been employed in orthopaedic surgery. During surgical procedures, Knee Angle Frames are a sort of instrument that aids surgeons in precisely measuring the degree of knee flexion/extension.
Dr. Richard L. Goldfarb of Harvard Medical School created the first Knee Angle Frame in 1983. During total knee arthroplasty (TKA) procedures, this gadget was utilised to evaluate the knee angle. The contraption was a straightforward metal frame with two arms situated either side of the knee. After adjusting the arms to the proper angle, they were clamped into position.
Numerous improvements have been made to the Knee angle frames accuracy and usability since its creation. Computer-assisted Knee angle frames were created in the 1990s. These tools more precisely measured the knee angle using digital imagery.
The usage of robotically aided Knee angle frames was the following significant development. The knee angle may be precisely adjusted using these devices using robotic arms. This makes it possible to assess the knee angle more precisely and maintain a more constant knee angle throughout the operation.
Knee angle frames that are 3D-printed have gained popularity over the past ten years. These tools can change the knee angle in any direction and were created using a 3D printer. This enables more accurate measurements and consistent outcomes.
Knee angle frames are a useful tool in orthopaedic surgery today. During total knee arthroplasty and other orthopaedic surgeries, they are utilised to precisely quantify the knee angle. knee angle frames are also employed in other medical specialities, such as physical therapy and sports medicine.
