Clinical Outcomes of Multiligament Knee Fracture Dislocation at Minimum 2-year Follow-up

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Sports Medicine

Background:

• Knee dislocation type V (KD V) fracture dislocations are severe injuries.
• Understanding outcomes is crucial for patient management and counseling.

Purpose of the Study:

• To evaluate clinical and functional outcomes of KD V fracture dislocations.
• To assess complications, reoperation rates, and arthritis progression.
• To analyze patient-reported outcome measures (PROMs) at minimum 2-year follow-up.

Main Methods:

• Retrospective review of a prospectively collected database (2001-2022).
• Inclusion of 11 patients with KD V fracture dislocations.
• Analysis of demographics, surgical details, complications, and PROMs (VAS, Tegner, Lysholm, IKDC).

Main Results:

• Mean follow-up of 6.4 years.
• High rates of concomitant injuries (fractures, nerve, vascular, cartilage, meniscus).
• 83% complication rate, 36% reoperation rate.
• Advanced osteoarthritis (mean KL grade 3.0).
• Satisfactory mid-term PROMs (e.g., Lysholm 79.0, IKDC 68.3).

Conclusions:

• Surgical management of KD V fracture dislocations is associated with high complication and reoperation rates.
• Radiographic evidence of advanced osteoarthritis is common.
• Patients achieve satisfactory functional outcomes at mid-term follow-up.
• Emphasizes the need for early recognition, multidisciplinary planning, and patient counseling.
