Ultrasound Guided Percutaneous Tenotomy - Is anyone familiar with?

Righ April t Knee History
2018 Road Bike Fall
2019 April Root tear to meniscus. Surgery to repair root tear to meniscus. failed
2021 Partial Knee Replacement EmergOrtho in Durham NC. Surgeon retired end of 2021. PKR failed.
2022 TKR Carolina Ortho, New Bern NC Lost flexion due to scar tissue Flexion stuck @ 72 degrees
End of 2022 surgeon put me under to perform Scar Tissue removal surgery (open Knee up), he attempted MUA - it worked - he was able to get flexion to 116 degrees - he did not do surgery. I attended PT every week for many many weeks. Flexion decreased again due to Scar Tissue.
2023 surgeon perform open knee surgery to remove scar tissue to regain flexion. Attended PT continuously, flexion of 113 degrees was accomplished. . Feb 2024 pain presented behind right knee. Currently in PT, recently presented to Duke Ortho in NC - CT Scheduled for 7/12/24 - 2 scenarios - bone spurs or fragment of cement left behind from TKR or scar tissue impinging popetiel tendon. Experiencing extreme pain daily with aching, sometimes numbness. my gut feeling is the scar tissue scenario affecting popetil tendon. If that the case, Dr Cline at Duke will perform Ultrasound Guided Percutaneous Tenotomy. Has anyone had this procedure done to their knee???
