20.500.12556/RUL-187329 Comparison of knees after patellofemoral stabilisation with asymptomatic contralateral knees Purpose: Patellofemoral instability (PFI) can significantly hinder and limit knee function. A widely accepted treatment of PFI is the medial patellofemoral ligament reconstruction (MPFLR), with or without additional procedures. This study aimed to evaluate postoperative functional outcomes in patients undergoing MPFLR by comparing the operated knee to the contralateral, asymptomatic knee using validated patient-reported outcome measures (PROMs). Methods: From a prospective database, 71 adult patients (18 years or older) treated for chronic unilateral PFI between 2012 and 2019 were enrolled in a retrospective cohort study. Patients undergoing MPFLR, either in isolation or with TTT, with an asymptomatic contralateral knee were included. Pre- and postoperative comparisons of Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner Activity Scale, and EQ-5D-3L were conducted. Statistical significance was set at p < 0.05. Results: Seventy-one patients were included; median follow-up was 3.8 years. Postoperatively, significant improvements were observed in all KOOS subscales (p < 0.001), EQ-5D-3L-TTO (D0.11, p = 0.002), and EQ-5D-VAS (D13, p < 0.000), alongside increased Tegner Activity Scale scores (D1, p = 0.002). Despite these gains, operated knees demonstrated persistent functional deficits compared to contralateral asymptomatic knees across all KOOS subscales (p < 0.001). EQ-5D-3L-TTO showed significant inter-limb differences; small nonsignificant differences were noticed in the EQ-5D-VAS and Tegner Activity Scale score. Conclusion: MPFLR significantly improves knee function, pain, and quality of life, yet does not fully restore function to the level of the asymptomatic contralateral knee. Persistent deficits highlight the need for further refinement in surgical techniques to optimize long-term outcomes. contralateral knee knee function outcomes medial patellofemoral ligament patellofemoral instability patient-reported outcomes tibial tubercle transposition patelofemoralna nestabilnost MPFL medialni patelofemoralni ligament tuberosistas tibije true false true Angleški jezik Slovenski jezik Članek v reviji 2026-09-10 09:32:53 2026-09-10 09:32:54 2026-09-11 04:28:27 0000-00-00 00:00:00 2025 0 0 Str. 464-470 Vol. 57 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 617.3 1873-5800 10.1016/j.knee.2025.10.007 286793731 1-s2.0-S0968016025002595-main.pdf 1-s2.0-S0968016025002595-main.pdf 1 35EBF0F03D5B20B443DAF52C97D96932 78ce58efa483d6170ee1ac150414738edbae38ff42d976560630aa912968afe8 6125b836-acea-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246914 https://www.sciencedirect.com/science/article/pii/S0968016025002595 0 380a5857-acea-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246913 https://www.thekneejournal.com/article/S0968-0160(25)00259-5/fulltext 1 d023dfc4-ace9-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246912 Medicinska fakulteta 0 0 0
