The surgery was performed by a team consisting of: Rafał Sotowski, MD, PhD, Bartosz Maciąg, MD, PhD (MUW Doctoral School) and the operating-theatre attendant Ewa Mielcarz, MSc.
The implant was prepared on the basis of an MRI scan and was thus adapted to the shape, location and size of the existing damage. This allowed to repair only the place of the damage, without the need to replace the whole joint or its major part. Thanks to the cooperation between the engineers and the doctors also the surgical instruments set was prepared for a specific patient and closely matched to the shape of his bones and joint surface, which allowed for the precise implant placement. The 48-year-old patient has long had a pain caused by sterile, osteochondritis necrosis (osteochondritis dissecans) of the medial femoral condyle. In this case, the increase of the implant also allowed to supply the bone defect (bone cyst).
At the same time a knee joint arthroscopy was performed to repair the damaged meniscus and then the prosthesis prepared for the patient was implanted. By reducing the extent of the procedure only to the point of a damage, the patient could already load the operated limb on the same day and start walking without pain more quickly.
