What is a Conversion of Prior Knee Surgery to Knee Replacement?
Patients who have had prior surgery involving their knee, such as hardware placed to secure a ligament reconstruction or to treat a fracture, are at increased risk of developing knee arthritis. When conservative measures are insufficient, conversion of the prior knee surgery to knee replacement may be recommended.
What Should I Expect During Conversion of Prior Knee Surgery to Knee Replacement?
Surgery is done under spinal or general anesthesia and may take longer to perform than a standard knee replacement. Dr. Phillips commonly uses robotic technology and/or image guidance for these procedures. After the initial approach is complete, any hardware that interferes with replacement of the knee will be carefully removed. The ends of the femur and tibia are then resurfaced to remove any damaged bone. Trial components are placed to ensure appropriate ligament balance and full range of motion prior to implanting the final replacement. Once all implants are in place, the incision is usually closed with a dissolvable suture beneath the skin.
What is the Postoperative Course After Conversion of Prior Knee Surgery to Knee Replacement?
Immediately after the procedure patients can typically put their full weight on their surgical leg. The majority of patients are discharged home on the day of surgery. Outpatient physical therapy is critically important for rehabilitating a conversion to total knee replacement, as patients who have had prior knee surgery are at increased risk of developing stiffness. Physical therapy takes place 2-3 times per week for 8-12 weeks on average. By 12 weeks, most patients are well recovered and returning to athletic activities. However, small gains can be made out to the 1 year mark when full recovery has occurred.
Is Conversion of Prior Knee Surgery to Knee Replacement Right For Me?
Conversion to knee replacement may be recommended when non-invasive treatments are not sufficient at combatting severe degenerative changes or instability of the knee. Dr. Phillips will thoroughly discuss the risks and benefits of surgery and any alternative options to ensure that the best treatment for you is mutually selected.
