A Nanoscopic Second Look Into the Knee Joint

The goal of this clinical trial is to look at how well different surgeries heal over time in patients that have previously undergone arthroscopic knee interventions. These procedures may include cartilage repair or grafting, meniscus repair or trimming, ligament reconstruction, cartilage smoothing, and treatments such as amniotic tissue or platelet rich plasma (PRP). Using a very small camera called a nanoarthroscope, doctors will take a "second look" inside the knee after surgery to see how it has healed. These findings will be compared to patient-reported outcomes, such as pain and function scores, as well as images taken during the original surgery. The goal is to determine whether this second look provides useful information that can help guide recovery and future care.
