“…Furthermore, both muscles have a long tendinous portion and can easily be harvested using a tendon stripper. There’s no need to reroute the tendons to bring them in a more anterior position at the site of the natural distal insertion of the patellar tendon as it has been reported [ 5 , 6 ]. The proximal insertion over the top of the patella with the folding back of the tendons provide a strong proximal anchor and a thick new patellar tendon.…”

Background Isolated Patellar Aplasia Hypoplasia is a very rare autosomal dominant disorder. Its treatment depends on the clinical manifestations that can vary widely. The lack of active extension, which can be responsible for frequent falls due to a knee instability, is the most frequent and disabling manifestation. We report an original technique that is a modification of the Galeazzi technique for recurrent dislocation of the patella to gain active extension in case of PTLAH. Case report A 7-year-old Caucasian boy with isolated Patellar Aplasia Hypoplasia and an extension lag of the right knee has been treated by a modified Galeazzi technique. The tendons of the semi-tendinous and gracilis muscles have been harvested and their distal insertion was kept intact. Both tendons were fixed over the top of the patella to restore knee active extension. After 6 years of follow up the patient is symptom free with a strong active extension of the operated knee. Conclusion Reconstruction of isolated hypoplasia of the patella by a modified Galeazzi procedure is a safe and reliable technique for skeletally immature patients offering satisfying long-term outcomes.

“…Congenital absence of patella is rare and is usually among the findings of the hereditary Nail Patella Syndrome, ischiopatellar dysplasia or orthopedic anomalies [ 36 , 37 ]. There were 9 subjects (2.4%) evaluated to have had ‘no patella’ with all 9 subjects’ ages ranging from 3 to 4 years old.…”

Fabella and patella variants: radiographic prevalence, distribution and clinical relevance in a population of black african descent

To evaluate the radiographic characteristics and prevalence of fabella and patella variants in an indigenous African population. This retrospective observational study of orthogonal knee radiographs of 377 consecutive subjects was conducted in Lagos, Nigeria, from February 2017 to November 2017. The presence of bipartite/multipartite patella, as well as the presence of fabella were noted. The craniocaudal diameter, anteroposterior diameter, fabello-femoral distance and fabello-tibial distance of the fabella were measured. P≤0.05 represented a statistically significant result. Three hundred and seventy-seven subjects were enrolled. The average age was 41.22±21.37 years with a range of 3-100 years old. There were 158 male (41.9%) and 219 female (58.1%) subjects. The prevalence of fabella was 11.94%. There was a positive correlation between age <47 and ≥47 and occurrence of fabella, P<0.015. There was no statistically significant difference between the mean male and female measured fabella diameters. The overall prevalence of bipartite and multipartite patella in this study was 2.12%. Among male and female subjects, the difference in prevalence of bi and multipartite patella was statistically significantly, P=0.03. The prevalence of fabella and patella variants was lower in this study compared to the findings in other populations and ethnicities. Sex and age were significantly correlated with fabella prevalence. The results reported in this study will facilitate future studies examining the correlations between fabella and patella variants and various knee pathologies in a population of Black African descent.

“…Congenital aplasia of the quadriceps muscle is a rare condition mentioned only a handful of times in the orthopedic literature. Most case reports describe an association with ipsilateral aplasia or dysplasia of the patella [1][2][3]. Ideally, treatment and surgical correction should start before adulthood.…”

Surgical Treatment of Leg Length Discrepancy and Knee Flexion Contracture Associated with a Congenital Absence of Quadriceps

We report the case of an 18-year-old male with congenital absence of quadriceps and hypoplasia of the patella who presented with a significant leg length discrepancy (LLD) and knee flexion contracture. Surgical management was aimed toward lengthening the limb, stabilizing the joint, and correcting the knee flexion contracture. Correction of a significant congenital LLD and knee flexion contracture poses challenges due to long-standing altered biomechanics. These are rare conditions for which no accepted surgical algorithms exist. It is essential to anticipate the biomechanical consequences of limb lengthening and flexion contracture correction that might arise and plan comprehensive interventions accordingly.
