Final answer:
The biggest risk of MPFL reconstruction is the potential for complications during and after the surgery, including damage to other structures in the knee and continued instability of the patella. There is also a risk of infection, blood clots, and scar tissue formation.
Step-by-step explanation:
The biggest risk of MPFL reconstruction, also known as Medial Patellofemoral Ligament reconstruction, is the potential for complications during and after the surgery.
During the procedure, there is a risk of damaging other structures in the knee, such as blood vessels or nerves. In addition, the reconstruction may not be successful in stabilizing the patella, leading to continued instability and potential re-injury.
After the surgery, there is a risk of infection, blood clots, and scar tissue formation. These complications can affect the overall outcome and recovery of the patient.
