1. Subjective evaluation of treatment of fractures of the distal femur using the KOOS scale per form edworse than a clinical evaluation using the KSS. 2. Post-operative management should emphasise pain relief and restoration of the performance of the treated lower limb to ensure good mobility without crutches. 3. Despite the use of modern operational methods of fracture fixation, treatment of distal femur fractures is still a challenge.

Open reduction and internal fixation using two perpendicular plates allows for achieving good stability of fixation, early rehabilitation and quick return to the desired level of activity, which contributes to a high percentage of good objective and subjective results of treatment. Subjective assessment of upper limb function after DHF surgery fully correlates with objective assessment.
