Correction of medial compartmental osteoarthritis knee joint by high tibial closed wedge osteotomy with tension band wiring and cortical screw fixation in a rural set up

Introduction: Osteoarthritis of the Knee is a Chronic debilitating disease excessive pressure leads to breakdown of the cartilage matrix, architectural changes in the subchondral bone, further altering the joint geometry. Aims and Objective: The effect of TBW with 2 cortical screws in cases of uni-compartmental O.A. Knee joint 32 cases were studied. Result: Lateral wedge osteotomy done 1.5 cm distal to joint margin to avoid fracture of tibial plateau intraoperatively. Height of wedge is taken dependent on varus angle calculated from x-rays, for each degree 1 mm height of wedge is taken. 2 cortical screws fixed distal to osteotomy site. Conclusion: It is a cost effective technique with use of minimum hardware and early post operative mobilization in patients who cannot afford Knee Arthroplasty in a rural set up.
