Summary

Bone grafting effectively treats tibial defects in total knee arthroplasty, with 22 of 24 grafts showing successful union and revascularization, avoiding collapse. This bone graft technique is recommended for significant tibial plateau defects or when cement columns exceed 5 mm.

Area of Science:

Orthopedic Surgery
Biomaterials Science
Radiology

Background:

Tibial defects are a common complication in total knee arthroplasty (TKA).
Bone grafting is a potential solution for reconstructing significant tibial bone loss.
Assessing graft incorporation and long-term outcomes is crucial for surgical success.

Purpose of the Study:

To evaluate the efficacy of bone grafting for tibial defects during primary or revision TKA.
To assess graft union, revascularization, and clinical outcomes.
To determine indications for bone grafting in TKA.

Main Methods:

Retrospective analysis of 24 knees undergoing TKA with bone grafts for tibial defects.
Follow-up period of three to six years.
Assessment of graft incorporation using tomograms, bone scans, and bone biopsy.

Main Results:

Successful union and revascularization were observed in 22 out of 24 bone grafts.
No clinical collapse occurred in 22 cases; one case of nonunion with collapse was noted.
Graft incorporation was evident by six months post-surgery.

Conclusions:

Bone grafting is a reliable method for treating tibial defects in TKA, achieving high rates of union and revascularization.
Indications include tibial defects involving ≥50% of the tibial plateau support or requiring >5 mm cement column.
Proper surgical technique, including adequate bony bed preparation, is essential for successful graft incorporation.
