What the study found
En bloc resection with nerve preservation and reattachment of the lateral stabilizers was associated with good oncological control and functional recovery in skeletally immature patients with proximal fibula giant cell tumour and preoperative common peroneal nerve neuropraxia.
Why the authors say this matters
The authors conclude that this approach may be important because proximal fibula giant cell tumour in skeletally immature patients is rare and poses a risk of common peroneal nerve injury and knee instability. The study suggests the procedure can address both tumour control and function in this setting.
What the researchers tested
The researchers carried out a retrospective case series of 20 patients aged 18 years or younger with histologically confirmed proximal fibula giant cell tumour and preoperative common peroneal nerve neuropraxia. All were treated between September 2023 and August 2024 with en bloc (Malawer type I) resection and reattachment of the lateral collateral ligament and biceps femoris, with at least 12 months of follow-up.
What worked and what didn't
All patients had negative surgical margins, and there was no recurrence at 12 months. Seventeen patients had complete common peroneal nerve recovery and 3 had partial recovery; 17 knees were stable, while 3 had grade I varus laxity. Complications included two superficial infections and one wound debridement, with no permanent deficits.
What to keep in mind
This is a retrospective case series with 20 patients and one-year follow-up, so the available summary does not describe a comparison group. The abstract also does not report longer-term outcomes beyond 12 months.
Key points
- Twenty skeletally immature patients with proximal fibula giant cell tumour and preoperative common peroneal nerve neuropraxia were treated with en bloc resection.

- Seventeen patients had complete common peroneal nerve recovery, and 3 had partial recovery.
- Seventeen knees were stable, while 3 had grade I varus laxity.
- Complications included two superficial infections and one wound debridement, with no permanent deficits.
