Yet, a recurring frustration is heard in literature and clinical practice: the effect is limited in time, varies per patient, and the precise duration of action varies greatly. A new preparation, <strong>Lipotris\u2122<\/strong> \u2014 a liposomal composite gel with HA \u2014 offers a mechanistically distinct approach that goes beyond classic viscosupplementation. A recently published prospective study in the <em>Journal of Cartilage &#038; Joint Preservation<\/em> (B\u0105kowski et al., 2026) supports both the mechanical properties and the clinical outcomes.   <\/p>\n<div style=\"position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%;\"><iframe style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\" src=\"https:\/\/www.youtube.com\/embed\/-LBZzQF-5hM\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>The problem: joint lubrication theory as an underestimated factor<\/strong><\/p>\n<p>In osteoarthritis, it is not just cartilage that is lost \u2014 the joint capsule hardens, the synovial fluid loses its viscoelastic properties, and the coefficient of friction in the joint increases significantly. This leads to a vicious cycle: more friction \u2192 more mechanical stress \u2192 more inflammation \u2192 further cartilage loss. <\/p>\n<p>Classic hyaluronic acid works primarily as a viscosupplement: it temporarily increases the viscosity of the synovial fluid. As soon as the HA is broken down by hyaluronidases (within 2\u20134 weeks), this effect disappears. Lipotris\u2122 introduces a fundamentally different concept: the <strong>&#8220;tribosupplement&#8221;<\/strong>.  <\/p>\n<p>&nbsp;<\/p>\n<p><strong>Mechanism of action: from sliding to rolling<\/strong><\/p>\n<p><strong>The role of liposomes<\/strong><\/p>\n<p><em>Lipotris Assembly Process<\/em><\/p>\n<p><strong>The core mechanism:<\/strong> liposomes actively interact with lubricin molecules (SUPERFICIAL ZONE PROTEIN) on the cartilage surface. Through this interaction, they transform the movement in the joint from a <em>sliding<\/em> to a <em>rolling<\/em> motion \u2014 a fundamental difference that reduces the coefficient of friction (\u00b5) to near-zero levels (&lt; 0.001). For comparison: classic HA achieves \u00b5-values of 0.02\u20130.05.  <\/p>\n<p><strong>Synergy with hyaluronic acid<\/strong><\/p>\n<p>The HA component (44 mg per 2 mL, 3 injections equal one treatment, thus 132 mg per 6 mL) plays a complementary role: it provides the viscoelastic framework that keeps the liposomes in suspension and ensures the biological effects that have long been known \u2014 CD44 receptor activation, inhibition of pro-inflammatory cytokines (IL-1\u03b2, TNF-\u03b1), and stimulation of endogenous HA production by synoviocytes.<\/p>\n<p>The combination of both components results in an effect described by the manufacturer \u2014 and now also in literature \u2014 as &#8220;active tribosupplementation&#8221;: not merely lubrication as a passive mechanical consequence, but active improvement of movement quality at the molecular level.<\/p>\n<p>&nbsp;<\/p>\n<table width=\"624\">\n<tbody>\n<tr>\n<td width=\"624\"><strong>\u25b6 KEY POINT<\/strong><\/p>\n<p>Lipotris\u2122 combines the biological effects of hyaluronic acid with the tribological properties of liposomes.
