The Fate of Overcorrection After Hemiepiphysiodesis in Valgus Deformities Around the Knee
(Lippincott Williams & Wilkins, 2023) Aksoy, Taha; Bakırcıoğlu, Sancar; Özdemir, Erdi; Ramazanov, Rafik; Aksoy, Mehmet Cemalettin; Yılmaz, Güney
Background:Tension band plating is widely used in the surgical treatment of coronal plane deformities around the knee. The rebound phenomenon after implant removal is a common complication of this technique. Overcorrection of joint orientation angles is a method to minimize the effect of the rebound phenomenon. This study aims to investigate the natural course of overcorrected joint orientation angles after plate removal in patients with genu valgum deformity. Methods:Patients who underwent hemiepiphysiodesis with tension band plating due to genu valgum deformity between 2010 and 2019 were retrospectively analyzed. Mechanical lateral distal femoral angles (mLDFA) and mechanical medial proximal tibial angles were calculated before plate application, before implant removal, and at the last follow-up. At the implant removal, mLDFA>90 degrees and mechanical medial proximal tibial angles Results:Seventy-two segments from 45 patients were included. For femoral valgus deformities (n=59), the mean mLDFAs at index surgery, implant removal, and the last follow-up were 79.8 & PLUSMN;3.9 degrees, 95.5 & PLUSMN;3.7 degrees, and 87.3 & PLUSMN;5.1 degrees, respectively. In the more and less than 10 degrees rebound groups, the median age of patients at index surgery were 66 and 101 months (P=0.04), the mLDFA during implant removal were 97.8 degrees and 94.4 degrees (P=0.005), and the mean amount of correction in mLDFA was 17 degrees and 13 degrees (P=0.001), respectively. At the last follow-up, joint orientation angles were found to be still overcorrected in 16 (22%), within normal limits in 36 (50%), and undercorrected in 20 (28%) segments. Ten (13%) segments required additional surgery due to residual deformity. Conclusions:Overcorrection with tension band plating is an effective modality in the treatment of genu valgum deformity. Rebound after plate removal increases as the age at index surgery decreases and the amount of conscious overcorrection increases. Most segments return to normal joint orientation angle limits after overcorrection. We recommend a mean of 5 degrees routine overcorrection in patients with genu valgum deformity to overcome the rebound phenomenon and to make future interventions easier if ever needed.

Joint Awareness After Fixed and Mobile-Bearing Total Knee Arthroplasty With Minimum 12 Years of Follow-Up: a Propensity Matched-Pair Analysis
(Elsevier, 2023) Bakırcıoğlu, Sancar; Aksoy, Taha; Çaglar, Ömur; Tokgözoğlu, A. Mazhar; Atilla, Bulent
Background: Many comparative articles studied mobile-bearing (MB) and fixed-bearing (FB) total knee arthroplasties (TKAs). Meta-analyses found no difference in survival or biomechanical outcome. This study aimed to compare long-term clinical results between fixed-bearing (FB) and mobile-bearing (MB) total knee arthroplasty (TKA) as well as patients' adaptation to their artificial joints.Method: TKAs performed with the same surgical protocol divided into categories according to the insert design preferred. 70 MB design TKAs were compared with 70 FB design TKAs utilizing propensity matching for parameters; gender, age, body mass index, coronal plane deformity, range of motion (ROM) and appropriateness criteria. Forgotten Joint Score-12 (FJS-12) was used to assess patients' ability to forget their artificial joints in daily life.Results: Patients had a mean follow-up of 15.6 (+/- 2.2) years. No difference was observed between groups for post-operative ROM, WOMAC, Knee Society Knee and Function Scores. The FJS-12 in the MB and FB groups were 66.1 and 72.8, respectively (P = 0.026). There was no significant difference in survival between both designs.Conclusion: This study suggests that in TKA, joint awareness is higher in MB compared to FB design. FJS-12 appears to be a sensitive measuring tool when comparing two designs and should be implemented in long-term follow-up.(c) 2023 Elsevier B.V. All rights reserved.

Outcomes of Limb Lengthening With Computer-Assisted Hexapod External Fixators in the Treatment of Fibular Hemimelia
(Lippincott Williams & Wilkins, 2023) Bakırcıoğlu, Sancar; Goker, Barlas; Yılmaz, Abdurrahman; Aksoy, Taha; Aksoy, Mehmet Cemalettin; Yılmaz, Güney
Background:Fibular hemimelia (FH) represents the most common deficiency of the long bones and is associated with multiple deformities. Reconstructive treatment with external fixators in FH restores normal lower extremity alignment and length with plantigrade feet for a balanced and effective gait. The aim of this study is to evaluate the outcomes of lower limb lengthening and simultaneous tri-plane deformity correction with a computer-assisted hexagonal external fixator in children with FH. Methods:A retrospective review was performed for FH cases treated with a computer-assisted hexagonal external fixator in a tertiary referral center. Leg length discrepancy (LLD), interphyseal angles, tibiocalcaneal distances, healing index (HI), and callus shapes were analyzed for radiologic evaluation, and the Pediatric Quality of Life Inventory (PedsQL) was used for functional assessment. Limbs with HI <50 days/cm, PedsQL >75, and without regenerate fractures were considered successful lengthenings. Results:Twenty-four limbs of 23 patients were included. The limbs were lengthened for a mean of 7.24 cm (range, 4.7 to 15.6). The initial LLD of 5.6 cm (range, 0.5 to 19 cm) increased to 1.7 cm (range, 0.1 to 6 cm), and the mean interphyseal angle was 12.7 degree (range, 1.5 to 54.2 degree), tibiocalcaneal distance was 0.85 cm (range, 0.1 to 1.7) at final follow-up. The most common regenerated bone morphology was cylindrical, as seen in 11 limbs (45.8%). The average PedsQL score was 83.5 (range, 69.5 to 96.7). Sixteen limbs (66.7%) had successful lengthening at their first, and 4 limbs (80%) had successful lengthening at their second surgeries. Seven limbs had complications requiring surgical intervention (29.1%), with 3 (12.5%) regenerate fractures after external fixators removal. Conclusions:Limb reconstruction with computer-assisted hexapod fixators is a successful and reliable option for the treatment of LLD in FH, and patients demonstrate good functional outcomes. Surgeons should be aware of potential complications and should utilize prophylactic measures when necessary.
