Introduction
Knee braces are devices that are worn on the lower extremity to provide support and stability to the knee joint. They are commonly used for the treatment of knee injuries, osteoarthritis, patellofemoral pain syndrome, and other conditions that affect the knee. This article will discuss the different types of knee braces available for treating bone-on-bone knee pain and the benefits and risks associated with their use.
Types of Knee Braces
Uni-compartment Offloader Braces
Uni-compartment offloader braces are designed to reduce pain by offloading (shifting) pressure from one compartment of the knee joint. They are only suitable for patients with moderate to severe osteoarthritis in one tibiofemoral compartment. These braces are typically made of metallic materials and feature a hinged design that allows for adjustment of the angle of the knee brace relative to the knee.
Tri-compartment Offloader Braces
Tri-compartment offloader (TCO) braces are a newer type of knee brace that address the limitations of uni-compartment offloaders by offloading pressure from all three knee compartments simultaneously. This allows for significant pain relief and improved mobility in patients with bone-on-bone knee pain in multiple compartments. TCO braces are typically made of lightweight materials and feature a polymeric hinge that allows for force reduction during knee flexion and extension.
Open Patellar Braces
Open patellar braces are designed to provide additional support to the patellofemoral joint, which is the area near the patella (kneecap). They typically feature a hole for the patella to sit in and are only suitable for patients with patellofemoral pain syndrome. Open patellar braces are typically made of lightweight materials and feature a flexible design that allows for dynamic movement of the knee joint.
Anti-rotation Tibial Shell Braces
Anti-rotation tibial shell braces are designed to reduce pain by preventing the tibia (shinbone) from rotating inward. They are typically made of lightweight materials and feature a rigid shell that contacts the tibial plateau (upper surface of the tibia) to prevent lateral translation of the tibia. Anti-rotation tibial shell braces are typically suitable for patients with外侧半月板损伤 (outer半月板损伤).
Custom Braces
Custom knee braces are made to fit the specific measurements and anatomy of an individual's knee. They can be made from a variety of materials and can be adjusted to provide optimal support and stability. Custom braces are typically more costly but can be more effective at reducing pain and improving function.
Benefits and Risks of knee brace usage
Benefits
Knee braces provide several benefits for patients with knee pain, including:
- Reduced pain: Many knee braces can reduce pain by offloading pressure from the affected joint surface.
- Improved function: Braces can help patients return to activity and perform daily tasks with greater comfort and stability.
- Prevention of injury: Properly fitted and adjusted knee braces can help prevent further injury by reinforcing the supporting structures of the knee joint.
Risks
While knee braces can be effective at reducing pain and improving function, there are some risks associated with their use, including:
- Skin irritation: All types of knee braces can potentially irritate the skin, especially if they are made from materials that are too rough or dense.
- Redness and swelling: Wearing a knee brace can cause temporary redness and swelling in some individuals, particularly if the brace is placed tightly against the skin.
- Inappropriate adjustment: If the knee brace is not fitted or adjusted properly, it can lead to increased pain and injury to the knee joint.
- Reduced mobility: In some cases, excessive use of a knee brace can lead to reduced mobility and weakness in the affected knee joint.
Conclusion
In conclusion, knee braces are a valuable tool for the treatment of knee pain and instability. They can provide significant pain relief and improved function for patients with bone-on-bone knee pain. However, it is important to carefully select the right type of brace and to follow the manufacturer's instructions for proper use. If you have bone-on-bone knee pain, it is recommended that you consult with a healthcare professional for a proper evaluation and treatment plan.
