Symptomatic Bipartite Patella Table 2.
A diagnosis of Sinding-Larsen-Johansson syndrome (osteochondrosis of the inferior pole of the patella) was made.
A spectrum of entities is involved in injury to the inferior aspect of the patella and the proximal patellar ligament, including Sinding-Larsen-Johansson syndrome, patellar sleeve avulsion and jumper's knee'.
Sinding-Larsen-Johansson syndrome is an osteochondrosis of the inferior pole of the patella and is often bilateral in nature.
Sinding-Larsen-Johansson syndrome is commonly seen in active adolescents between 10 and 14 years of age, as described in our patient.
There is no known association between Sinding-Larsen-Johansson syndrome and malignancy as described in our patient.
Osteochondrosis of the tibial tuberosity (Osgood-Schlatter disease) and osteochondrosis of the patella (Sinding-Larsen-Johansson syndrome) occur at tendinous insertions into the patella at the distal and proximal levels, respectively.
Imaging of Sinding-Larsen-Johansson syndrome may require a combination of radiographs, MRI and ultrasound.
Minimally displaced fractures as those seen with Sinding-Larsen-Johansson syndrome are often managed conservatively and non-operatively.
