Medial Open-Wedge Supramalleolar Osteotomy for Patients with Takakura 3B Ankle Osteoarthritis: A Mid- to Long-Term Study.

ABSTRACT: It is controversial whether supramalleolar osteotomy is suitable for Takakura Stage 3B osteoarthritis or not. The aim of this study was to evaluate the outcomes of supramalleolar osteotomy in patients with Takakura 3B osteoarthritis. From February 2008 to August 2013, supramalleolar osteotomy was performed in 21 patients matching the inclusion criteria. The mean patient age at operation was 53.7±5.8 years (range: 39 to 61 years). The mean duration of follow-up was 87.7±19.5 months (range: 61 to 125 months). The radiologic evaluation included the tibial articular surface (TAS) angle, tibial lateral surface (TLS) angle, and talar tilt (TT) angle. Functional assessment was performed with use of the AOFAS, VAS, SF-36, and AOS. All patients were followed. TAS angle improved from 82.8±2.4 to 90.3±2.3. TLS angle changed from 77.5±2.8 to 79.4±2.7. The preoperative TT angle and postoperative TT angle were 13.4±3.6 to 4.8±3.6, respectively. For functional evaluation, the preoperative VAS and AOFAS-AH scores were 5.7±1.3 and 48.0±15.8, while the postoperative VAS and AOFAS-AH scores were 2.5±1.9 and 74.8±11.5. The mean SF-36 scale improved from 41.2±13.1 to 66.7±14.9. The AOS score improved from 61.4±12.5 to 27.5±17.8. 1 patient underwent total ankle replacement 3 years postoperatively. 4 patients remained stage 3B including the TAR one. 4 improved to stage 3A, 11 improved to stage 2, and 2 improved to stage 1. Supramalleolar osteotomy combined with auxiliary procedures can restore the malalignment of ankle joint and modify the abnormal stress distribution so as to achieve functional improvement and improve radiographic stages.

Project description:ObjectiveThe purpose of this study was to evaluate the usefulness of preoperative planning of the femurofibular angle (FFA) in medial open-wedge high tibial osteotomy (OWHTO) for mild medial knee osteoarthritis.MethodsThirty-two patients (32 knees) with mild medial knee OA were retrospectively reviewed. The patients underwent preoperative planning of the FFA for OWHTO. For preoperative planning, a full-length weight-bearing X-ray photograph of the lower limb was opened within Adobe Photoshop Software, and a targeted corrective mechanical axis line of the lower limb and its intersecting point at the lateral tibial plateau surface was drawn using rectangle selection and filling tools. A frame, which encircled the tibia and fibula, was created around the predicted osteotomy plane and then rotated until the ankle center was on the targeted mechanical axis line. Subsequently, a distal femoral condyle line and a proximal fibula axis line were drawn, and the angle between the two lines was measured and defined as the femurofibular angle (FFA). During biplane OWHTO, the preoperatively determined FFA was used to complete the correction of the mechanical axis. During follow-up, the postoperative mechanical weight-bearing line (WBL) of the lower limb, the mechanical femorotibial angle (mFTA), and the FFA were measured and compared with the preoperatively determined values.ResultsThe mechanical WBL shifted from a preoperative value of 25.36 ± 5.02% to a postoperative value of 56.19 ± 0.10% from the medial border along the mediolateral width of the tibial plateau, and it was 56.57 ± 0.08% at the final follow-up (P < 0.01). The preoperatively determined value was 56.25%, and no significant difference was found compared with postoperative week-one and final follow-up values (P > 0.05). The mFTA was corrected from a preoperative varus of 4.02 ± 0.63° to a postoperative week-one valgus of 2.37 ± 0.28°, and it had a valgus of 2.48 ± 0.39° at the final follow-up (P < 0.01). No significant difference in the valgus was found compared with the postoperative week-one, final follow-up and preoperatively determined valgus of 2.34 ± 0.26° (P > 0.05). The postoperative week-one and final follow-up FFAs were 90.34 ± 1.53° and 90.33 ± 1.52°, respectively, and no significant difference was found compared with the preoperatively determined value of 90.12 ± 1.72° and the intraoperative setting value of 90.25 ± 1.67° (P > 0.05). All corrected values were within the acceptable range of preoperative planning.ConclusionPreoperative planning of the FFA may be useful in OWHTO for patients with mild medial knee OA. Satisfactory correction of the postoperative targeted mechanical axis line of the lower limb can be obtained.

Project description:BackgroundWhile proximal first metatarsal osteotomy combined with distal soft tissue realignment is accepted as standard treatment of moderate to severe hallux valgus with metatarsus primus varus, none of the described proximal metatarsal osteotomies address the hyper-obliquity of the first metatarsocuneiform joint. An opening-wedge osteotomy of the medial cuneiform can potentially correct the 1-2 intermetatarsal angle (IMA) in addition to normalizing the hyper-obliquity of the first tarsometatarsal (TMT) joint. The purpose of this study was to retrospectively review the early radiographic and clinical results of the use of a medial cuneiform opening-wedge osteotomy fixed with a low-profile wedge plate combined with distal soft tissue realignment for the treatment of hallux valgus.MethodsFourteen feet (13 patients; 2 male and 11 female, average age 56 years, range 22-75) with hallux valgus underwent an opening-wedge osteotomy of the medial cuneiform fixed with a low-profile nonlocking wedge plate combined with distal soft tissue realignment. The mean preoperative hallux valgus angle (HVA) was 32 degrees and the IMA was 16 degrees. HVA, 1-2 IMA, proximal first metatarsal inclination (PFMI), and presence of osteoarthritis of the first TMT joint were assessed on preoperative and final postoperative radiographs. Final postoperative radiographs were also evaluated for radiographic union and hardware failure at an average of 7 months (range, 3-19 months) postoperatively.ResultsA mean intraoperative correction of 19 degrees and 7 degrees was achieved for the HVA and IMA, respectively. The mean HVA was 22 degrees and the mean IMA was 11 degrees at the time of final follow-up. At final follow-up, a recurrence of the deformity was observed in 12/14 feet. There were 2 nonunions-one plate failure and one screw failure. No first TMT joint instability or arthritis was observed. All patients were ambulatory without assistive device in either fashionable or comfortable shoe wear.ConclusionMedial cuneiform opening-wedge osteotomy resulted in unreliable correction of HVA and IMA at short-term follow-up with a high rate of early recurrence of hallux valgus deformity and a complication rate similar to that of the Lapidus procedure. This procedure cannot be recommended for addressing hallux valgus in the setting of increased obliquity of the first TMT joint.Level of evidenceLevel IV, case series.
