Total Knee Replacement (TKR) is a highly successful procedure for restoring mobility and reducing pain in individuals with severe knee arthritis. However, as with any major surgery, there are potential complications that patients should be aware of. Understanding these risks can help individuals prepare for a smooth recovery and optimize their rehabilitation outcomes.
Common Complications After TKR
1. Stiffness and Limited Range of Motion (ROM)
Post-operative stiffness can limit knee flexion, making it difficult to perform daily activities. Research published in The National Library of Medicine highlights that early and consistent physical therapy is crucial in preventing stiffness and achieving optimal range of motion (ROM).
The image to the right illustrates knee flexion progress over time following surgery, highlighting key percentile benchmarks for recovery. Tracking progress against these benchmarks can help patients and healthcare providers assess rehabilitation success.
2. Infection
While rare, infections can occur in the surgical site or deep within the joint, sometimes requiring additional procedures. Signs of infection include redness, swelling, fever, and increased pain.
3. Blood Clots (Deep Vein Thrombosis - DVT)
TKR patients have a higher risk of developing blood clots in the legs. Preventative measures such as early mobilization, compression devices, and blood-thinning medications can significantly reduce this risk.
4. Implant Loosening or Failure
Over time, some patients may experience implant loosening due to wear and tear. This can cause pain and instability, sometimes necessitating revision surgery.
Tracking Recovery and Preventing Complications
The reference charts included in this blog depict knee flexion recovery trajectories, demonstrating expected improvements in Active Range of Motion (AROM) over time. By comparing individual progress to these standard benchmarks, patients can identify potential setbacks and adjust their rehabilitation plans accordingly.
Conclusion
While TKR is a transformative procedure, understanding potential complications can help patients take proactive steps in their recovery. By following a structured rehabilitation plan, monitoring ROM progress, and using innovative recovery tools, patients can enhance their outcomes and minimize risks.
How NeeHab Can Help
Rehabilitation devices like the Flexion or Flexion & Extension Device support recovery by promoting gentle yet consistent knee flexion and extension exercises. Using such tools can aid in preventing stiffness and optimizing outcomes after TKR.
