It typically manifests as pain when going up and down stairs, as well as when getting up from a squatting position. Diagnosis is based on clinical examination (patellar crepitations, effusions on exertion, often limited patellar travel) and imaging. Axial X-rays of the patella can quantify cartilage narrowing, often predominantly on the lateral facet. MRI and, if there is any doubt about the origin of the pain, SPECT-CT help to precisely locate the responsible compartment.<br><br>Morphological factors (trochlear dysplasia), traumatic or surgical history and certain morphotypes (varus\/valgus) constitute contributing factors. In many cases, osteoarthritis is isolated to this compartment, while the femoro-tibial joints remain unaffected; this configuration opens the door to partial prosthetic solutions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-55250a39 e-con-full conteneur_vid_1 e-flex e-con e-child\" data-id=\"55250a39\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-409afb77 titre_vid_2 elementor-widget elementor-widget-heading\" data-id=\"409afb77\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">When to suggest a patellofemoral prosthesis<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1f1ad3d5 elementor-widget elementor-widget-text-editor\" data-id=\"1f1ad3d5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>The indication is discussed when osteoarthritis is isolated to the patellofemoral compartment, with a preserved tibiofemoral joint and a satisfactory limb axis. The major contraindications are associated tibiofemoral involvement and inflammatory arthropathies. Analysis of the axis, patellar stability and muscle chains is essential. In case of clinical doubt about the origin of pain, SPECT-CT can objectify the hyperactivity of the patellofemoral compartment and support the decision.<br><br>Patient information focuses on the objective (relieve pain and restore function) and alternatives (targeted rehabilitation, podiatric correction, infiltrative treatments). When internal unicompartmental osteoarthritis coexists, an association with a unicompartmental femoro-tibial prosthesis can be considered at the same time as surgery.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-448d6db9 e-con-full conteneur_citation_vid_0 e-flex e-con e-child\" data-id=\"448d6db9\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-892da450 conteneur_citation_vid_1 aleft elementor-widget-icon-box wgl-icon-box wgl-view-default elementor-widget elementor-widget-wgl-infobox\" data-id=\"892da450\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wgl-infobox.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wgl-infobox_bg_wrapper\"><\/div><div class=\"wgl-infobox\"><div class=\"wgl-infobox_wrapper wgl-layout-left\"><span class=\"media-wrapper icon-wrapper\"><span class=\"wgl-icon\" ><svg class=\"icon elementor-icon e-font-icon-svg e-fas-quote-left\" aria-hidden=\"true\" viewbox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M464 256h-80v-64c0-35.3 28.7-64 64-64h8c13.3 0 24-10.7 24-24V56c0-13.3-10.7-24-24-24h-8c-88.4 0-160 71.6-160 160v240c0 26.5 21.5 48 48 48h128c26.5 0 48-21.5 48-48V304c0-26.5-21.5-48-48-48zm-288 0H96v-64c0-35.3 28.7-64 64-64h8c13.3 0 24-10.7 24-24V56c0-13.3-10.7-24-24-24h-8C71.6 32 0 103.6 0 192v240c0 26.5 21.5 48 48 48h128c26.5 0 48-21.5 48-48V304c0-26.5-21.5-48-48-48z\"><\/path><\/svg><\/span><\/span><div class=\"content_wrapper\"><div class=\"wgl-infobox-title_wrapper\"><h5 class=\"wgl-infobox_title\"><span class=\"wgl-infobox_title-idle\"><span class=\"elementor-repeater-item-56c0705\">The patellofemoral prosthesis is a bit of a poor relation of the knee, but it has real indications.<\/span><\/span><\/h5><\/div><\/div><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-9eb2bc99 e-con-full conteneur_vid_1 e-flex e-con e-child\" data-id=\"9eb2bc99\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d0d4b046 titre_vid_2 elementor-widget elementor-widget-heading\" data-id=\"d0d4b046\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Modern implants and surgical technique<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ae3a074c elementor-widget elementor-widget-text-editor\" data-id=\"ae3a074c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Current implants are most often of the &quot;onlay&quot; type, with anatomical geometry, associated with patellar resurfacing depending on the case.
