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

Figure 1 Preoperative lateral radiograph of the left knee and measurement of the patellar height. A: Before the second operation, the fracture healed, and the Caton–Deschamps index was 0.38; B: Before the third operation. The ratio of the red dotted line and yellow dotted line indicates that the Caton–Deschamps index was 0.12, and the ratio of the white dotted line to the blue dotted line indicated that the Insall–Salvati index was 0.42; C: The contracted patellar tendon is approximately 35.0 mm in length and 11.3 mm in thickness.
