Clinical Details

Clinical and radiological findings:  A 51-year-old male with a history of alcoholism presented with an isolated low-energy injury to the distal femur. The patient, described as non-compliant, insisted on early weight-bearing postoperatively. Radiological assessment revealed a simple intra-articular distal femur fracture without comminution or metadiaphyseal dissociation. Neurovascular examination was unremarkable.

Preoperative Plan

Planning remarks:  The preoperative plan involved achieving anatomic reduction and interfragmentary compression of the fracture fragments. A lateral approach was selected to facilitate the placement of a large antiglide plate for stabilization.

Surgical Discussion

Patient positioning:  Supine position on a radiolucent table, with the affected limb prepared for lateral access.

Anatomical surgical approach:  A lateral parapatellar approach was utilized, involving an incision along the lateral aspect of the distal femur. The vastus lateralis muscle was elevated subperiosteally to expose the fracture site. Careful dissection allowed for direct visualization and reduction of the articular surface.

Operative remarks: 

The surgeon emphasized the importance of achieving anatomic reduction and stable fixation to allow for early weight-bearing. The fixation strategy included interfragmentary compression and the application of a large antiglide plate to ensure stability. The surgeon expressed confidence in the construct's ability to withstand early mobilization, challenging traditional postoperative weight-bearing restrictions for articular fractures.

Postoperative protocol:   Immediate full weight-bearing as tolerated, with emphasis on early mobilization to promote cartilage healing in the absence of shear forces.

Follow up:   Not specified.

Orthopaedic implants used:   Large antiglide plate, interfragmentary compression screws.
