Nail-patella syndrome in Saudi Arabia with new features and surgical procedures: the first described study

The purpose of this study was to reveal the occurrence of nail-patella syndrome (NPS) in Saudi Arabia together with the detection of abnormal attachment of lateral meniscus in the left knee and new surgical procedures applied to the right and left knee, reported for the first time in this study. This was a case study of a 23-year-old young man presenting with bilateral knee pain, giving way and locking since the age of 15 years. Clinically, most of the NPS features were noted, including ocular problems. The complex features affected both knees, especially the previous attempted surgeries for recurrent dislocation of patellae. Deficient ligaments were reconstructed using the Leeds-Keio ligament, starting with the right knee and continuing with the left knee 6 months later. Early and late follow-up showed favorable outcome of surgery revealed as independent ambulation and stable right and left knees. In conclusion, NPS, although rare, presents a complex problem and unexpected surgical outcome, and we recommend this procedure with close follow-up.
