⚡ TL;DR(Too Long; Didn't Read)

There was nosignificantdifference in craniocaudal and transverse dimensions, but the anteroposteriordimension (thickness) of the distalpatellae articulating the knee joint had agreater thickness (P = 0,01).Conclusion: Evidence from this study has shown that a bettergrowth can be expected in the distal fragment of the patellacompared with theproximal fragment following treatment with Niebauer-King’s quadricepsplasty in children with congenitaldislocation ofthe knee.Level of Evidence: Level IV, Therapeutic Study

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: The aim of this study was to ultrasonographically measure the dimensions of the proximal and distalpatellarfragments to determine whether postoperative growth differences existbetween the fragments in children with congenitaldislocation of the kneetreated by Niebauer Kings quadricepsplasty.Methods: This retrospective study included six congenitaldislocated knees of four children with arthrogryposis multiplexcongenita (AMC)(3 girls; mean age = 40 months; age range = 9–44 months), presented with severe hyperextension kneecontractures,which were treated by Niebauer-King’s quadricepsplasty.The transverse, craniocaudal, and anteroposteriordimensions of the patellaewere measured ultrasonographically 20 (range = 6-42) months postoperatively by a singleradiologist.Results: The mean transverse, craniocaudal, and anteroposteriordimensions of proximal and distal halves of the patellae were:11.46 (7.0-16.9)–10.5 (8.0-14.4); 17.4 (14.0-21.0) –16.68 (14.5-19.3); 6.76 (5.6-7.9) –7.76 (7.0-9.4) mm respectively.
