High tibial osteotomy in medial compartment osteoarthritis and varus deformity using the Taylor spatial frame: early results

Abstract

We report the early results of high tibial osteotomy (HTO) in medial compartment osteoarthritis (OA) and varus deformity using the Taylor spatial frame (TSF). Between October 2005 and April 2007, 9 patients with medial compartment OA and varus deformity underwent TSF application and medial opening wedge HTO. Pre- and post-operative Oxford knee scores, SF-12 and visual analogue pain scores were recorded along with radiographic outcomes. Median follow-up was 19 months (range 15–35). Mean age at operation was 49 years (range 37–59). The median time spent in the frame was 18 weeks (range 12–37). The mean preoperative Oxford knee score was 28.7. This improved to a mean of 35.4 post-operatively (P = 0.0142). 6 (67%) patients had a documented pin-site infection. With TKR as an end point, the survival rate of HTOs was 88.9% at a median of 19 months follow-up. This study demonstrates that in selected patients the TSF provides a viable treatment option for performing HTO in medial compartment OA with varus deformity.

Management of Osteoarthritis Knee by Graduated Open Wedge High Tibial Osteotomy in 40-60 Years Age Group Using Limb Reconstruction System: A Clinical Study

“…The mean age at the time of osteotomy was 49.2 years which is comparable to a study by Robinson PM et al, [11]. Females were the predominant sex as seen in a study by Nakamura et al, [19].…”

“…It may be done proximal or distal to the tibial tubercle and may be stabilized by internal or external fixation [11][12][13][14]. The first HTO was done by Jackson which was distal to the tibial tubercle while Coventry did his HTO proximal to the tibial tubercle which had the advantage of high union rates due to quality of bone proximal to tibial tubercle [15,16].…”

Opening Wedge High Tibial Osteotomy with Combined Use of Patient-Specific 3D-Printed Plates and Taylor Spatial Frame for the Treatment of Knee Osteoarthritis

“…The application of TSF on the correction of the rotation of the limbs and bone joints on the plane and deformity shortening is a very mature technology [ 11 ]. HTO with TSF was presented as a viable treatment option in active patients with early medial compartment OA [ 12 ]. After the computer's precise calculation, a “correction prescription” is developed individually for each patient through the slow distraction osteogenesis to achieve the purpose of while correcting while building up bones in three dimensions and six degrees.…”

Association of a hi-tech with a bio-tech technique in the treatment of early osteoarthritis of the knee: a case report

“…in the reported case, the presence of a minimal varus (3°) was not considered a contraindication for this technique although it can be a negative prognostic factor for the final result. to obtain partial unloading of the medial compartment the main alternative treatment in adult patients is high tibial osteotomy (8,9). in this case, since the varus was minimal, the Kinespring system was considered the optimal solution, as it unloads medial compartment without definitively altering the knee anatomy, given that the implant is totally reversible.…”
