Objectives This study aims to present the 10-year results and complications of two-hole tension band plate hemiepiphysiodesis for coronal deformities around knee in a large population from a single center. Patients and methods Seventy-seven patients (46 boys, 31 girls; mean age 93±36 months; range, 22 to 181 months) who underwent temporary hemiepiphysiodesis around knee between January 2009 and January 2019 with two-hole tension band plates were retrospectively evaluated. Improvement of joint orientation angles and mechanical axis deviations, deformity correction rates, etiology groups, and complications were noted. Results A total of 166 bone segments (93 femurs, 73 tibias) were included in the study. Mean follow-up duration after the implantation was 36±17 (range, 12 to 88) months. Plates were removed at mean 18±8 (range, 7 to 47) months of implantation. Of the bone segments, 95.2% (n=158) responded successfully to the plates. Mean correction rate of mechanical lateral distal femoral angle in femoral valgum deformity was 0.94±0.43° (range, 0.17 to 2.22)/month and mean correction rate of mechanical medial proximal tibial angle in tibial valgum deformity was 0.62±0.36° (range, 0.11 to 1.55)/month. Mean correction rate of mechanical lateral distal femoral angle in femoral varum deformity was 1.3±0.8° (range, 0.48 to 2.92)/month and mean correction rate of mechanical medial proximal tibial angle in tibial varum deformity was 0.94±0.49° (range, 0.26 to 1.67)/month. The most common complication observed was rebound deformity seen in 41.2% (n=70) of the bone segments. Nine bone segments had persistent hemiepiphysiodesis despite plate removal. Four screw breakages (three metaphysial and one epiphysial) were observed. Conclusion Two-hole tension band plate hemiepiphysiodesis appears to be an effective and safe method for the correction of coronal deformities around knee.

BACKGROUND: Articular cartilage repair has been a challenge in orthopedic practice due to the limited self-regenerative capability. Optimal treatment method for cartilage defects has not been defined. We investigated the effect of decellularized human placental (DHP) scaffold, mesenchymal stem cells (MSC) and platelet-rich plasma (PRP) on hyaline cartilage regeneration in a rat model. METHODS: An osteochondral defect was created in trochlea region of the femur in all groups, bilaterally. No additional procedure was performed in control group (n = 14). Only the DHP scaffold was applied to the P group (n = 14). The DHP scaffold and 1 9 10 6 MSCs were applied to the PS group (n = 14). The DHP scaffold and PRP were applied to the PP group (n = 14). The DHP scaffold, 1 9 10 6 MSCs and PRP were applied to the PSP group (n = 14). Outcome measures at 12 weeks included Pineda histology score and qualitative histology. RESULTS: The mean Pineda scores of P, PS, PP, and PSP groups were significantly better than the control group (p = 0.031, p = 0.002, p \ 0.001, p \ 0001, respectively). There was no statistically difference in mean Pineda scores of P, PS, PP, and PSP groups (p [ 0.05). CONCLUSION: In conclusion, the DHP scaffold appears to be a promising scaffold on hyaline cartilage regeneration. The augmentation of DHP scaffold with MSCs and PRP combinations did not enhance its efficacy on articular cartilage regeneration.

Background/Aim: Proximal humerus fractures are common in elderly patients. Treatment of three and four-part fractures is especially controversial in these patients. In recent years, surgical options have been widely used, especially among shoulder surgeons. The purpose of this study was to compare clinical results of conservative and arthroplasty methods. Methods: Between 2016 and 2020, 30 patients who were treated for Neer type 3 and type 4 proximal humeral fractures were included in the study. Patient data were evaluated retrospectively and then divided into three groups. Group 1 was treated conservatively, group 2 underwent hemiarthroplasty; and group 3 underwent reverse total shoulder arthroplasty. CONSTANT and visual analog scale (VAS) scores and radiological results at six months were evaluated retrospectively from patient records. At the last control they have been evaluated with CONSTANT, University of California/Los Angeles. (UCLA), and VAS scores. Results: Twenty-three (76.7%) of the patients included in the study were females. The mean age was 73.5 (5.7) years. The mean follow-up period was 33 (2.5) months. The mean follow-up periods in groups 1–3 were 33.3 (2.9), 32.8 (2), and 32.2 (2.9) months, respectively. When the CONSTANT scores of the patients were compared at the sixth month, they were observed to be better in the reverse total shoulder arthroplasty group (P = 0.001). Final control CONSTANT scores in the hemiarthroplasty group were lower than in the other groups (P = 0.001) and similar in the reverse shoulder prosthesis and conservative treatment group (P = 1). When the UCLA scores of all groups were compared, the mean UCLA scores were found to be significantly higher in groups 1 and 3 compared to group 2 (P = 0.001). When the VAS scores of the patients were compared, a significant difference between all groups was detected (P < 0.05). The highest VAS scores were observed in group 2, the second highest in group 1, and the lowest in group 3. Conclusion: For treatment of proximal humerus fractures in the elderly, patients should be evaluated according to activity levels and expectations, and surgical treatment should be suggested rather than ordered.
