Summary
SERVERE VARUS DEFORMITY WITH TIBIAL DEFECT RECONSTRUCT WITH SCREWS AND AUGMENTATION WITH CEMENT
Abstract
Introduction
Severe deformity of knee is many times associated with tibial defect. Tibial defect are addressed in many well know different ways. Aim of the study to analyse and report short term results of tibial defect reconstruction of small to moderate size, not having instability, with screw and cement surgical technique.
Method
The type and the size of the bone defect are the major concern in Osteoarthritis and regarding the re-construction of the bone defect and the surgical technique. Surgical technique is demanding because the defect crater could be variable and reconstruction multiple with cortical or cancellous screws and cement as a filler.
Nov 2017 to January 2021, 68 pts,(Bil -28 ,Unilateral - 40).
Male 30 (bilateral- 11 , Unilateral -28 ) Female- 38 (bilateral-17 , unilateral- 12 ) total No. of 96 knees, in the age range of 60yrs. All were Varus deformity – Osetoarthries 68, traumatic – 4.
All patients had an uncontained posterior medial peripheral defect on the tibial plateau > 5mm deep of small to moderate size
Results
The clinical results are obtained including the range of movements knee society KSS & OKS scores good to excellent and follow up none had Cement breakage or loosening in radiologically and alignment maintained . None had instability in 1 ½ yr. Average follow-up was 1.2 yrs. There was no gap in between the Implant and cement. There was no infection secondarily.
Discussion
Many a times uncontained defect are seen posterior medial aspect specially in varus defect and it is varies from small to moderate area with depth. It is evaluated retrospectively all patients with Osteoarthritis a under gone total Knee arthroplasty posterior stabilize
Knee having small to moderate defect and deformity reconstructed with screw and cement with above mentioned parameters, X-ray analysis of alignment there is no recurrence of deformity or instability of the knee in our series
Study provides encouraging results regarding the stability of knee, alignment of the rectangular bone block-cement bone interface at a mean follow-up of more than 1.2yr.
