In March 2014, a 14 years old girl presented with a normal perinatal history and developmental milestones, genu valgum (Figure-1), severe pain in knee joints which was progressive in nature and difficulty in walking.
For correction of genu valgum, a surgical procedure of medial close wedged osteotomy at distal end of femur was done.
Exaggerated genu valgum up to 7 years of age is physiologic and not pathologic .
In congenital longitudinal deficiency of the fibula, genu valgum is common .
She had a maternal half-sister who was 12 years old and healthy and the patient also had a younger 2-year-old full sister who had started to show the same signs of widening of the leg bones and genu valgum
If you see patients with genu valgum
frequently it is a good idea to give the parents a hand-out to study at home.
Patients are also noted to have deformities secondary to osteoarthritis and joint laxity, including cervical spine instability, genu valgum, genu varum, and genu recurvatum.
6) The authors also noted that 75% of patients with genu varum, genu valgum, or genu recurvatum underwent surgical correction.
This patient's main skeletal problems are the degeneration and contracture of the hips and the progressive, symmetric genu valgum
(knock knees), that have affected the way she walked.
Rarely genu recurvatum, genu varum, genu valgum
, hypoplasia of cruciate ligaments, pectus excavatum, scoliosis, increased lumbar lordosis, spondylolisthesis, spondylosis, spina bifida, etc.
The increased angle of anteversion is associated with CDH, Perthes, slipped epiphysis, cerebral palsy, poliomyelitis, postural defects, squinting patellae, apparent genu valgum
, tibial extorsion, flat foot, and in toeing.
The length of the trunk with narrow chest, the stunted growth of upper and lower extremities, knock knee with genu valgum
are quite common findings in Achondroplasia (9) and EVC syndrome.
She had mild genu valgum
deformity but no wasting or hypertrophy of calf muscles.
