Mid-term results of total knee arthroplasty after high tibial osteotomy

Background The outcome of total knee arthroplasty (TKA) after high tibial osteotomy (HTO) is still controversial. In order to determine if osteotomy has any effect on this outcome we performed a medium-term review of a cohort of patients with knee osteoarthritis. Materials and methods Thirty-two patients (38 knees), who were treated with a HTO before the TKA during the last 8 years, were compared with a matched group who underwent primary TKA. The knees were evaluated preoperatively and postoperatively according to the scoring systems of the Knee Society and Hospital for Special Surgery (HSS). The anteroposterior tibiofemoral alignment, the Insall–Salvati patellar position ratio, range-of-motion and the location of the lateral joint line, were also recorded. The patients were reviewed with a mean follow-up of 4.5 years after TKA. Results The preoperative and postoperative knee scores had no statistically significant differences between the two groups. So was the case with the intraoperative releases, blood loss, thromboembolic or neurologic complications and infection rates in either group. Access to perform the arthroplasty was reportedly more difficult and took an average of 25 min longer. A significant difference (p < 0.05) was detected in terms of impingement of the tibial stem on the lateral tibial cortex, patellar subluxation and patella baja between the two groups but this did not have any influence on the outcome of the prosthesis. Knee alignment and stability so as range of motion (ROM) measurements were also found with no statistical significance. Conclusion Although we did manage to detect statistically significant differences mainly in radiographic results between the two groups, this situation did not appear to influence the clinical outcome of the patients, however. The fact that most of the patients had good or excellent results at an average follow-up of 4.5 years suggests that HTO does not have a significant negative effect on later TKA.     

Total knee arthroplasty coincident with high tibial osteotomy

Established lower limb alignment and knee stability are the two main prognosis factors influencing good functional result and prosthesis life. During Total Knee Arthroplasty (TKA), correction of tibial extra-articular deformity cannot be achieved without ligament balancing. Excessive valgus deformity after a failed high tibial osteotomy (HTO) necessitates a much larger resection of bone from the medial tibial plateau resulting in a trapezoidal extension gap. In overcorrected valgus knee patients after failed HTO, meticulous preoperative planning is required to predict complementary procedures needed to achieve flexion-extension balance with optimal postoperative lower limb alignment. This article details the preoperative planning involved and the intraoperative technique used in such cases. We describe a planning methodology consisting of measuring medial and lateral distance between future femoral and tibial orthogonal resection lines, drawn on valgus and varus stress radiographs (arrows). If the medial distance (medial arrows) on the valgus stress radiographs is longer than the lateral arrows on the varus stress radiographs, a lateral release will be necessary to achieve a rectangular extension gap during TKA procedure. However, the lateral release needed to compensate medial bone resection is limited. This limit must not exceed 10 millimeters (about 8 to 10° of valgus malunion). Over this limit, total knee arthroplasty plus corrective tibial osteotomy is one of the solutions. We prefer to insert prosthesis inside the “ligament box”; without any ligamentous release. The limb alignment is achieved with corrective tibial osteotomy. We propose and describe how to carry out TKA based on a rectangular extension gap, associated, in the same procedure, with a HTO to restore a neutral alignment of the leg.     

Long-term outcome after high tibial osteotomy

Introduction The frequency of tibial osteotomy in the treatment of osteoarthritis of the knee has decreased due to the demanding surgical procedure and the rising number of total knee replacements (TKR). Only few data exist concerning survival rates after high tibial osteotomy (HTO) with a follow-up exceeding 10 years. We want to present long-term results with a follow-up of more than 18 years after operation. Materials and Methods Survival rates and the influence of age, gender and the mechanical axis were investigated in 134 lateral closing-wedge osteotomies in 111 patients. Results The survival rate was 94% after 5 years, 79.9% after10 years, 65.5% after 15 years, and 54.1% after 18 years. Age had a significant influence on the survival and gender and the mechanical axis had no significant influence. Conclusion We conclude, that with a 54.1% survival after 18 years HTO is a useful facility to protract the implantation of a total knee prosthesis. An erratum to this article can be found at

Role of high tibial osteotomy in medial compartment osteoarthritis of the knee: Indications,surgical technique and outcomes

Knee osteoarthritis (OA) is the most common joint disorder worldwide. In particular, primary knee OA often presents with a varus malalignment. This increases the loads going through the medial compartment resulting in cartilage degeneration and symptomatic arthritis. High tibial osteotomy (HTO) is the workhorse surgical procedure for treating medial knee OA. When performed precisely in the hands of an experienced surgeon, HTO can delay or avoid knee arthroplasty. Of note, outcomes of knee arthroplasty are at best unpredictable in patients of younger age. Hence, there is a growing need for joint preservation procedures for younger patients presenting with knee OA, of which HTO is one. Through this article, the authors of whom all are joint preservation surgeons with a special interest in osteotomy hope to share from their experience as well as the available literature on the indications, perioperative planning, surgical technique, outcomes as well as pearls and pitfalls of HTO.     

Recovery of muscle strength after high tibial osteotomy

 To assess muscle strength after high tibial osteotomy (HTO) using percutaneous drilling, we prospectively evaluated the isometric and isokinetic muscle torque of the thigh before operation and after operation over time. We evaluated 27 joints of 26 patients with a mean age of 66 years. The muscle torque/weight ratio was seen to decrease, and the hamstrings/quadriceps (H/Q) ratio increased at 3 months after HTO; both ratios showed no significant difference at 6 months. Improved muscle strength appeared at isometric extensor of 50°, not 80°, and at slow isokinetic speeds of 30°/s, not 90°/s. There was no significant difference in terms of the age of patients regarding the recovery of muscle strength. We also compared patients with a varus angle of ≥5° and those with a varus angle <5° before the operation. In terms of extension, the group with varus angles <5° showed a greater postoperative increase in isometric torque at 80° flexion of the knee and isokinetic torque at 90°/s than did the group with varus angles of ≥5°.

High tibial osteotomy combined with anterior displacement of the tibial tubercle for osteoarthritis of the knee

Summary Eighty-nine knees with medial tibiofemoral and patellofemoral osteoarthritis were treated by high tibial osteotomy between 1972 and 1978, and 71 were followed up for at least 5 years, the average being 6 years and 9 months. There was no significant loss of motion as recorded before and after operation. In most patients pain decreased or disappeared, and walking ability was regained. Evaluation using the Japanese rating system showed that there were Good and Fair results in 86% of the cases. The average tibio-femoral angle in the Good group was 169±5°. The angles in the Poor group varied over a wide range. There were serious complications such as nonunion, malunion and infection in a few cases. In Group 1 (30 knees) high tibial osteotomy alone was performed. In Group 2 (41 knees) there were associated osteoarthritic changes in the patellofemoral joint and a high tibial osteotomy was combined with anterior displacement of the tibial tubercle (ventralisation). In comparison, Group 2 had better results with regard to both clinical and radiological evaluation.Read at the 16th Congress of the Societe Internationale de Chirurgie Orthopedique et de Traumatologie, London, England, 5th October, 1984
