Separation of bipartite patella in nail–patella syndrome: a case report

Several Infra‐cranial Non‐metric Variations in a Single Neolithic individual: A Common Genetic Underlying Predisposition?

“…Soren and Waugh, ; Anderson, ), but it is likely that genetic predisposition plays a role in some cases (Aloisio, ). It is also noteworthy that a case of bipartite patella has been described in association with an autosomal dominant disorder called nail–patella syndrome (Kumar et al ., ).…”

Arthroscopic Management for Bipartite Patella: A Systematic Review

“…Regardless of scale, all patients except 1 (42 of 43; 97.7%) were pain-free at final follow-up. One patient (2.3%) in the Kumar et al 15 study experienced the only postoperative complication in this review. At 3 weeks after arthroscopic lateral release with medial plication, the patient twisted his knee causing separation of the bipartite fragments requiring ORIF.…”

“…Following the Saupe classification, 1 case (2.3%) was type 1; 2 cases (4.7%) were type 2; and 39 cases (91.0%) were type 3. Kumar et al 15 reported that their case (2.3%) did not fit into the Saupe classification, as the patella appeared to have 2 primary ossification centers. Only 3 cases (7%) had a history of trauma to the knee before the pain started: the patients of Carney et al 6 and Yoo et al 30 had blunt trauma to the anterior knee, and the patient of Azarbod et al 4 jumped from a height of 2 m. All patients received a minimum 3 months of nonoperative treatment, such as nonsteroidal anti-inflammatory drugs and physical therapy, before attempting arthroscopic treatment.…”
