While the distal consequences of calcaneus deformity are well described, its long-term influence on proximal joint biomechanics remains insufficiently characterized [<a href=\"#R4\">4<\/a>]. In a fixed dorsiflexed hindfoot, premature anterior displacement of the ground reaction force (GRF) vector occurs, shifting the sagittal mechanical axis anterior to the center of knee rotation, generating an external hyperextension moment [<a href=\"#R5\">5<\/a>].<\/p>\n<p>Chronic exposure to an anteriorly directed sagittal load may lead to progressive attenuation of the posterior capsule and structural adaptation of periarticular soft tissues [<a href=\"#R5\">5<\/a>,<a href=\"#R6\">6<\/a>]. Over time, this can culminate in severe genu recurvatum and secondary tibiofemoral degeneration. Although coronal-plane interactions between foot deformity and knee osteoarthritis have been investigated, particularly in planovalgus alignment [<a href=\"#R4\">4<\/a>], the specific relationship between pes calcaneus deformity and progressive sagittal knee instability has received limited attention.<\/p>\n<p>Genu recurvatum in the setting of neuromuscular disease poses unique reconstructive challenges [<a href=\"#R7\">7<\/a>]. Unconstrained or semi-constrained knee designs may inadequately control sagittal instability when posterior capsular structures are incompetent, and quadriceps strength is compromised [<a href=\"#R7\">7<\/a>,<a href=\"#R8\">8<\/a>]. Recurrence of hyperextension has been reported with less constrained implants, particularly in neurologically impaired patients [<a href=\"#R8\">8<\/a>,<a href=\"#R9\">9<\/a>,<a href=\"#R10\">10<\/a>]. Rotating hinge prostheses, by providing intrinsic sagittal stability independent of soft-tissue integrity, therefore represent a logical reconstructive solution in advanced cases [<a href=\"#R11\">11<\/a>,<a href=\"#R12\">12<\/a>].<\/p>\n<p>The present report describes two cases of long-standing, untreated pes calcaneus deformity secondary to spina bifida that developed progressive genu recurvatum and end-stage knee osteoarthritis. These cases illustrate a potential distal-to-proximal sagittal failure cascade linking hindfoot dorsiflexion to chronic knee hyperextension and degenerative joint collapse. Recognition of this biomechanical relationship may have implications not only for arthroplasty strategy but also for early deformity correction to prevent secondary proximal joint degeneration.<\/p>\n<h2>Case Report<\/h2>\n<div class=\"jxi-subsection\">\n<h4>Case 1<\/h4>\n<p>A 53-year-old housewife presented with pain in her right knee and difficulty in walking for the past 5 years.

The left knee showed 10\u00b0 varus and approximately 5\u00b0 of hyperextension. The quadriceps and hip abductors were normal bilaterally. Examination of the feet revealed callosities on the heel pad, calcaneus-valgus alignment of the hind foot, a high longitudinal arch, and a supinated forefoot. These findings were more pronounced on the right side.<\/p>\n<p>The radiographs showed increased calcaneal pitch (44\u00b0), decreased tibiocalcaneal angle (36\u00b0), and increased talocalcaneal angle (61\u00b0), suggestive of severe pes calcaneus deformity (<a href=\"#F1\" class=\"jxi-fig-ref\">Fig. 1e<\/a>).

Both patients required complex knee reconstruction with a RHK prosthesis. While the local effects of pes calcaneus deformity in neuromuscular conditions are well documented, its long-term influence on knee sagittal alignment has received comparatively limited attention. Compensatory mechanisms between joints, especially in response to coronal-plane deformities, have been documented in a few studies [<a href=\"#R1\">1<\/a>,<a href=\"#R2\">2<\/a>]. However, there is limited literature on secondary sagittal-plane deformities of the knee and their surgical management after the development of degenerative arthritis. Unlike primary osteoarthritis associated with coronal malalignment, this pattern represents a predominantly sagittal-plane failure mechanism.<\/p>\n<p>Pes calcaneus deformity is characterized by fixed ankle dorsiflexion resulting from paralysis or weakness of the gastrocnemius\u2013soleus complex, with relative preservation of dorsiflexors and evertors [<a href=\"#R2\">2<\/a>,<a href=\"#R13\">13<\/a>]. In normal gait, the plantar flexors modulate forward tibial progression during mid-stance and help maintain the GRF vector within a controlled relationship to the knee joint center [<a href=\"#R13\">13<\/a>,<a href=\"#R14\">14<\/a>]. Loss of plantarflexion power, combined with fixed dorsiflexion, causes premature anterior displacement of the GRF relative to the tibiofemoral axis [<a href=\"#R6\">6<\/a>]. This anterior shift creates an external hyperextension moment at the knee [<a href=\"#R6\">6<\/a>]. In patients with quadriceps weakness, the knee may adopt hyperextension as an adaptive stabilizing strategy to achieve passive stability during stance [<a href=\"#R1\">1<\/a>,<a href=\"#R6\">6<\/a>,<a href=\"#R10\">10<\/a>].<\/p>\n<p>Chronic exposure to repetitive hyperextension loading may progressively attenuate the posterior capsule and ligamentous stabilizers, leading to fixed sagittal instability [<a href=\"#R9\">9<\/a>,<a href=\"#R10\">10<\/a>,<a href=\"#R11\">11<\/a>]. Altered tibiofemoral mechanics and abnormal contact loading may further accelerate degenerative changes within the knee joint [<a href=\"#R11\">11<\/a>,<a href=\"#R15\">15<\/a>]. Previous literature has emphasized coronal-plane coupling between foot deformity and knee osteoarthritis, particularly in pes planovalgus alignment and medial compartment loading [<a href=\"#R4\">4<\/a>]. However, reports specifically linking fixed calcaneus deformity to progressive genu recurvatum and secondary sagittal degeneration remain sparse [<a href=\"#R6\">6<\/a>,<a href=\"#R16\">16<\/a>]. The present cases extend this understanding by suggesting persistent hindfoot dorsiflexion may act as a distal contributor to progressive sagittal knee instability.<\/p>\n<p>From a reconstructive perspective, TKA in the presence of fixed recurvatum presents substantial challenges. Conventional cruciate-retaining or posterior-stabilized implants depend on intact soft tissue tension and extensor mechanism function to maintain sagittal stability [<a href=\"#R8\">8<\/a>]. In neuromuscular patients with posterior capsular incompetence and quadriceps weakness, recurrence of hyperextension has been reported with less constrained designs [<a href=\"#R8\">8<\/a>,<a href=\"#R17\">17<\/a>]. RHK prostheses offer a promising solution by stabilizing the knee without relying on the already compromised bony and soft-tissue structures [<a href=\"#R17\">17<\/a>]. The extension-stopper design in rotating-hinge prostheses helps prevent recurrence and correct instability (<a href=\"#F2\" class=\"jxi-fig-ref\">Fig. 2a<\/a>). RHK has been successfully used in neuromuscular conditions, such as poliomyelitis, with excellent pain relief, improved function, and enhanced activities of daily living [<a href=\"#R8\">8<\/a>,<a href=\"#R17\">17<\/a>]. However, concerns regarding the recurrence of recurvatum and the need for revision in approximately 7% of cases, as early as 6.2 years, have also been reported [<a href=\"#R12\">12<\/a>].<\/p>\n<p>Although some literature exists regarding the influence of pes planovalgus deformity on TKA outcomes [<a href=\"#R4\">4<\/a>], studies on the pes calcaneus are lacking. The present cases underscore the potential long-term consequences of untreated pes calcaneus deformity. While early correction of hindfoot malalignment in childhood is primarily advocated to prevent ulceration and functional gait dysfunction [<a href=\"#R1\">1<\/a>,<a href=\"#R2\">2<\/a>], its role in mitigating proximal joint degeneration warrants further study. Early correction of the pes calcaneus deformity in childhood can provide a plantigrade foot, potentially preventing secondary changes in the proximal joints [<a href=\"#R1\">1<\/a>,<a href=\"#R18\">18<\/a>]. Methods of surgical treatment of pes calcaneus deformity can be divided into two categories. In young and adolescent patients, the standard treatment is surgical correction of soft-tissue deformities and tendon transfer from functionally preserved muscles [<a href=\"#R1\">1<\/a>,<a href=\"#R18\">18<\/a>]. At an older age, triple arthrodesis, corrective osteotomy of the calcaneus, and wedge-shaped foot resections are performed [<a href=\"#R1\">1<\/a>,<a href=\"#R18\">18<\/a>].<\/p>\n<h2>Conclusion<\/h2>\n<p>These cases suggest untreated pes calcaneus may represent an underrecognized distal contributor to progressive sagittal knee failure in selected neuromuscular populations. However, other factors, including intrinsic quadriceps weakness and age-related degeneration, likely contributed to the development of osteoarthritis. Nonetheless, the consistent pattern of a long-standing pes calcaneus deformity, progressive recurvatum, and advanced sagittal instability suggests a plausible mechanical association warranting further investigation.<\/p>\n<blockquote class=\"jxi-boxed-text\">\n<p><strong>Clinical Message<\/strong><\/p>\n<p>Long-term effects of uncorrected pes calcaneus deformity on the proximal joints and axial skeleton are less studied.
