Lower Limb Salvage For Tumours Around The Knee Using Oncological Resections And Megaprosthetic Reconstructions

Area of Science:

• Orthopedic Oncology
• Surgical Reconstruction
• Tumor Management

Background:

• Tumors around the knee present a significant challenge in limb salvage surgery.
• Understanding clinical presentation and outcomes is crucial for effective treatment planning.

Purpose of the Study:

• To document the clinical presentation of knee tumors.
• To evaluate the outcomes of limb salvage with oncological resections and megaprosthetic reconstructions.
• To analyze functional recovery, disease-free survival, and complications over a 5-year follow-up.

Main Methods:

• A 13-year descriptive case series of adult patients undergoing tumor resection and megaprosthetic reconstruction around the knee.
• Analysis of variables including knee function, disease-free survival, and complications.

Main Results:

• Giant cell tumors (n=41) and osteosarcomas (n=24) were most frequent in a population aged 16-53 years.
• Average Musculoskeletal Tumor Society (MSTS) score was 84.65%.
• Complications included infections (12.32%), local recurrence (8.21%), and 7 (9.58%) mortalities.

Conclusions:

• Giant cell tumors and osteosarcomas are the most common knee tumors, affecting a younger demographic.
• Oncological resections with megaprosthetic reconstruction offer a viable limb salvage option.
• The procedure yields reasonable outcomes for the majority of patients despite potential complications.
