“…Bowleg deformity has been observed in 50–60% of children with achondroplasia. 1 , 3 – 5 , 7 The bowleg deformity is caused by fibular overgrowth relative to the tibia both proximally and distally. This causes altered relationships of the tibia and fibula at the knee and ankle.…”

“…Achondroplasia is one of the most common osteochondrodysplasias with an incidence of 1 in 26,000 live births. 1 , 2 It is a form of disproportionate short-limbed rhizomelic dwarfism. Characteristic features include relative macrocephaly, frontal bossing, depressed nasal bridge, bowing of lower limbs, flexion deformity of the elbow, dislocation of the radial head, trident hands, and hyperlordosis.…”

Introduction Achondroplasia is one of the most common osteochondrodysplasias with an incidence of 1 in 26,000 live births. Bowing of lower limbs can cause significant morbidity in this population. The use of the Ilizarov external fixator to tighten collateral ligaments of the knee in children has not been reported in the literature. We report the technique and early results of lateral collateral ligament (LCL) tightening with correction of genu varum in children with achondroplasia. Materials and methods A retrospective review of children with achondroplasia presenting with bowleg deformity who were treated by corrective osteotomy and LCL tightening was conducted. Between 1998 and 2003, 12 patients (24 limb segments) underwent this procedure and were included in the study. All patients had grade III LCL laxity preoperatively. Pre- and postoperative anteroposterior standing mechanical axis radiographs were evaluated. The final outcome was graded using the grading system of Paley et al. Results All patients had bilateral corrections. The Ilizarov external fixator was used in 10 patients and the Orthofix limb reconstruction system in 2 patients. The bony realignment was achieved through monofocal or bifocal tibial osteotomies. The LCL was tightened in all limb segments using the Paley’s type II strategy. The final result was graded as excellent in 20 limb segments and good in 4 limb segments. One patient developed transient common peroneal nerve palsy, four developed grade II pin site infections, and there was premature consolidation of the tibial regenerate in one patient.

Purpose of review We present the reader with insight on the most common disorders of the knee in newborns and infants. Knee issues in this population may confuse the first contact physicians due to certain peculiarities of the immature immune system, small size and underdevelopment of joint anatomy. Data presented here are recent and significant, and something to bear in mind when caring for children of this age. Recent findings With the advent of new diagnostic methods, a shift in the causative agent of pediatric knee infections has been noted. Minimally invasive methods such as arthrocentesis and arthroscopy are successfully employed in treatment of knee problems in newborns and infants. A trial of conservative therapy in congenital patellar instability can give good results, and obviate the need for surgery in some cases. Various syndromes that affect the knee have specific characteristics that need to be recognized early to avoid problems in the future. Summary Although rare, knee problems in infants can and do occur. Their cause varies significantly and good outcomes require a multidisciplinary approach. Early diagnosis, referral and initiation of treatment protocols can significantly influence the fate of the joint and with it the patients’ functional status for life.
