“…The valgus alignment on the unaffected side, with so-called “long leg arthropathy (Fig. 3 )” [ 2 ], was present in 6.3% of the Crowe IV patients (Fig 2 ). In the Crowe IVa group, a valgus deformity on the unaffected side, “long leg arthropathy”, was observed in 13.6% of the patients, but it was not observed in any of the patients in the Crowe IVb group Figs.…”

“…This is the name applied to the particular form of hip OA associated with ankylosis, arthrodesis or any condition of the hip joint in which the rotation is severely restricted. On the other hand, Brattstrome et al described that a leg length discrepancy (LLD) causes disease of knee known as “long leg arthropathy” [ 2 ]. William et al described that a leg-length inequality of 1 cm or more increased the odds of incident symptomatic knee OA in both the shorter and longer legs compared with patients who have an inequality less than 1 cm [ 3 ].…”

Background:Severe hip osteoarthritis is known to lead to secondary osteoarthritis of the knee joint. It is not clear whether contracture or a leg length discrepancy is more important in determining the knee alignment.Methods:In this study, 48 hips in 48 patients with a unilateral completely dislocated hip (Crowe IV) were recruited. The patients were divided into two groups (Crowe IVa and IVb). The Crowe IVa group had completely dislocation with psudo-articulation, and the Crowe IVb group had completely dislocation without psudo-articulation. The lower limb alignment was divided into three patterns according to the femorotibial angle; varus (≥176 degrees), neutral(170 to 175 degrees) and valgus(≤169 degrees).Results:The combination of valgus alignment on the affected side and varus alignment on the unaffected side, so-called “windswept deformity” was observed in 12.5% of the patients; this included 18.2% and 7.7%, in the Crowe IVa and Crowe IVb groups, respectively. The valgus alignment on the unaffected side, namely “long leg arthropathy,” was found to have occurred in 6.3% of the patients, including 13.6% of the patients in the Crowe IVa group; there were no cases of long “leg arthropathy” in the Crowe IVb group.Conclusion:The lower limb alignment on the unaffected side had a tendency to be varus in the Crowe IV patients. The “windswept deformity” was observed in each of the groups; however, “long leg arthropathy” was only found in the Crowe IVa group.
