Bone grafting in primary uncemented total knee arthroplasty

Area of Science:

• Orthopedic surgery
• Biomaterials science

Background:

• Tibial defects are a common complication in uncemented knee replacements, potentially compromising implant stability and function.
• Reconstruction of significant tibial defects often necessitates bone grafting to restore bone stock and facilitate implant fixation.

Purpose of the Study:

• To evaluate the efficacy of bone grafting in addressing tibial defects associated with uncemented ICLH (Intra-articular Cementless Hip) and Freeman Samuelson knee replacements.
• To describe the patterns of bone loss, grafting techniques, and associated soft tissue procedures in these complex cases.

Main Methods:

• A retrospective review of 42 patients who underwent uncemented ICLH and Freeman Samuelson knee replacements with bone grafting for tibial defects.
• Analysis of pre- and post-operative data, including imaging to assess graft incorporation and clinical outcomes.

Main Results:

• Bone grafting demonstrated a high success rate, with 98% of grafts achieving union.
• The study details the specific patterns of tibial bone loss and the surgical techniques employed for grafting and soft tissue management.

Conclusions:

• Bone grafting is a valuable and reliable method for reconstructing tibial defects in patients undergoing uncemented knee replacement surgery.
• Successful graft union supports the use of bone grafting for improving outcomes in deformed and arthritic knees requiring revision or complex primary procedures.
