Outcome Measures

Primary Outcomes (1)

  • The Knee Injury and Osteoarthritis Outcome Score - sport (KOOS Sport)

    KOOS-sport is a standardized and validated patient-reported instrument used in order to assess knee and knee associated problems with regards to activity. The subscale sport is one five subscales: pain, ADL, symptoms, sport and QOL in the KOOS questionnaire . A total score of 100 indicates no symptoms, and 0 indicates major symptoms.

    12 month follow up

Secondary Outcomes (13)

  • Perceived Pain

    6 weeks, 3+6+12 months

  • Patient-reported pain reactions

    6 weeks, 3+6+12 months

  • Pain sensitivity

  • Muscle strength

  • Time to bone union

Study Arms (2)

Intramedullary Nail

ACTIVE COMPARATOR

Intramedullary Nailing: Alignment will be obtained by closed or limited open reduction of the fracture. A standard reamed intramedullary nail is inserted. Access above the patella, through the patella tendon or parapatellar access is used according to surgeon preferences. One or more cortical screws may be used if deemed appropriate due to fracture pattern. Patients are administered preoperative antibiotics (Dicloxacillin) 15 minutes before surgery commences. Postoperative antibiotics is administered by discretion of the surgeon based on individual patient considerations.

Procedure: Intramedullary Nailing

External Ring fixator

EXPERIMENTAL

External Ring fixation: Closed or limited open reduction of the fracture is performed. A circular frame is attached on both sides of the fracture. Connection to the bone is obtained by hydroxyapatite coated half pins and/or k-wires with olives as needed according to surgeon preferences. One or more cortical screws may be used if deemed appropriate due to fracture pattern. After applying the ring fixator alignment is assessed radiologically and corrected both peri- and postoperatively. Patients are administered preoperative antibiotics (Dicloxacillin) preoperatively 15 minutes before surgery commences. Following surgery antibiotics are continued until wounds, pin- and wire perforations are dry.

Procedure: External Ring fixation
