Autogenous iliotibial band enhancement combined with tendon lengthening plasty to treat patella baja: A case report

Figure 2 Arthroscopic release measurements were followed by range of motion (ROM) measurements and open surgery. A: ROM of the knee joint after arthroscopic release was slightly improved compared with the preoperative ROM; B: The approach was made from 5 cm above the superior pole of the patella to the tibial tubercle. A periosteal elevator (black arrow) was used to mobilize the contracted patellar tendon (white star) and identify its medial and lateral margins.
