M0634 099 Deutsche Gesellschaft für Orthopädie und Unfallchirurgie Deutsche Gesellschaft für Orthopädie und Orthopädische Chirurgie Deutsche Gesellschaft für Unfallchirurgie Berufsverband für Orthopädie und Unfallchirurgie Deutscher Kongress für Orthopädie und Unfallchirurgie (DKOU 2025) Poster | Kniechirurgie Berlin 20251028 20251031 AB19-4299 TextObjectives and questions: To evaluate the efficacy of different treatment modalities on range of motion (ROM) and functional outcomes in patients with histologically proven knee arthrofibrosis following total knee arthroplasty (TKA) in a prospective study with operative patients from March 15, 2020, to March 15, 2022.Material and methods: A total of 30 patients with knee arthrofibrosis were prospectively enrolled and nonrandomly divided into three groups based on treatment:Group A (ASK: Arthroscopic Surgery of the Knee, n=16),Group B (Tub: Tuberosity transfer and total knee arthroplasty revision , n=8), andGroup C (Konservativ: Conservative treatment, n=6). Pre- and post-operative ROM (extension and flexion) and Oxford scores were compared. Statistical analyses included intra-group and intergroup comparisons using t-tests, ANOVA, and Wilcoxon tests.Results: Pre-operative ROM averaged 12.2° (SD=12.1) for extension and 69.7° (SD=20.1) for flexion in Group A (ASK), 12.5° (SD=12.5) for extension and 59.4° (SD=40.8) for flexion in Group B (Tub), and 1.7° (SD=4.1) for extension and 87.5° (SD=20.9) for flexion in Group C (Konservativ). Post-operatively, ROM improved significantly in Groups A and B, with extension increasing to 4.4° (SD=5.7) and 3.4° (SD=3.9), and flexion to 90.9° (SD=11.9) and 80.0° (SD=29.5), respectively (p < 0.05). Oxford scores improved from 45.19 (SD=6.8) to 32.5 (SD=7.6) in Group A (ASK) and from 49.0 (SD=6.9) to 35.1 (SD=10.7) in Group B (Tub) (p < 0.05). Group C (Konservativ) showed no significant improvement in ROM or Oxford scores (p > 0.05). Intergroup analysis revealed no significant difference between Groups A (ASK) and B (Tub) (p > 0.05), but both surgical groups showed superior outcomes compared to Group C (Konservativ) (p < 0.05).Discussion and conclusions: Surgical interventions (ASK and Tub) significantly improve ROM and functional outcomes in patients with knee arthrofibrosis post-TKA, outperforming conservative treatment. These findings suggest that surgical approaches are effective in enhancing joint flexibility and quality of life, reducing the need for revision surgeries. 0 0 0 0
