 <bold id="strong-285d38b6f43a4ca9a522db6dd4a5948e">Diagnosis</bold>

Based on clinical, radiological and open biopsy, giant cell tumour of medial condyle of left tibia was diagnosed.

 <bold id="strong-099d617913a34998a30d5ef3e6f88b3b">Treatment</bold>

Curettage+High speed burr+Electrocautery+Hydrogen peroxide [Extended curettage and Adjunct therapy]

Cavity was filled with Subchondral cortico-cancellous autograft + Gel foam+ PMMA bone cement[Sandwich technique]

Bone was stabilized with 6.5 mm cancellous screw and 4.5 mm cortical screw.

Inj Zolendronic acid 5mg IV once in a month was given post-operatively, for 4 months

<bold id="strong-9437da94dcab415b8d6ea8ccef8e143e">Follow up X-ray: After 3 months and 3 years</bold> Conclusion

GCT is a locally aggressive tumour treated successfully with extended curettage, bonegraft and cementation (Sandwich technique)

Inj Zolendronic acid was given to prevent the recurrence.

No recurrence of the tumour is seen after 3 years of follow up.

Extended curettage and IV Zolendronic acid are important in prevention of recurrence of GCT
