Objective: Since, there is no standardized technique for the treatment of focal cartilage defects that can recreate original cartilage tissue; researchers continue to explore and evaluate various treatment modalities. This study compared post-operatke healing of cartilage defects after treatment with small-diameter-hole microfracture (SDHM) technique with that of traditional microfracture technique. The effects of the hole density and augmentation with hyaluronic acid-based acellular matrix (HA-based AM) on cartilage healing were also investigated. Methods: Articular cartilage defects measuring 5 mm in diameter and 3 mm in depth were created in each femoral trochlear groove of 21 New Zealand rabbits. Rabbits were assigned to seven groups comprising six knees each. The rabbits were sacrificed 12 weeks later, and the regenerated cartilage was harvested for histological evaluation using the Wakitani scoring system. Results: All defects were filled with regenerated tissue macroscopically. Group I (14; range 10-14 points) had significantly higher Wakitani score than in groups VI (6; range 1-11 points) and VII (5; range 3-10 points) (p=0.043 and p=0.016, respectively). No significant differences were observed among the other groups. Augmentation with HA-based AM did not contribute to cartilage healing. Conclusion: Improved cartilage healing was observed with increasing SDHM density than with traditional microfracture technique. SDHM combined with HA-based AM implantation did not improve the quality of the regenerated cartilage.

Purpose This study was performed to compare short and standard-length tapered-wedge-type femoral stems in single-stage bilateral total hip arthroplasty (THA) through a direct anterior approach (DAA). Materials and methods The patients were divided into two groups according to their femoral stem types as short tapered-wedge stem and standard-length tapered-wedge stem groups. Outcome parameters were the surgical time, estimated blood loss (EBL), length of stay (LOS), thigh pain, Harris Hip Score (HHS), and visual analog scale (VAS) score clinically, and canal fill ratio (CFR), coronal plan alignment of the stems, subsidence, and postoperative leg length difference (LLD), radiologically. Results The short-stem group and standard-length-stem group consisted of 20 patients (40 hips, mean age 52.0 +/- 14.1) and 22 patients (44 hips, mean age 49.4 +/- 11.9), respectively. There were no significant differences between the groups in terms of mean surgical times (p = 0.6), EBL (p = 0.2), LOS (p = 0.2), the rate of thigh pain (p = 0.4), improvements in HHS (p = 0.4) and VAS scores (p = 0.6), LLD (p = 0.3), amount of subsidence (p = 0.9), and varus or valgus misalignment (p = 0.7). The CFR at the level of the lesser trochanter was significantly higher in the short-stem group (0.79 +/- 0.1) than the standard-length-stem group (0.73 +/- 0.1) (p < 0.01). Conclusion In single-stage bilateral THA through DAA, short, tapered-wedge femoral stems provide similar radiographic and functional results to standard stems at short-term follow-up.

Objective To report the functional and radiological results of unusual comminuted fractures of the proximal humerus, treated with ‘closed reduction and external fixation’ (CREF) using hybrid-type unilateral external fixators (EFs). Patients and methods Between January 2012 and June 2013, eight patients (mean age 62.6; range 48–84 years) with comminuted proximal humeral fractures extending to the humeral head and one-third proximal diaphysis were treated with CREF using hybrid-type EFs. Functional results were evaluated in terms of shoulder ranges of movement, Constant, DASH, and VAS scores, and radiological results were evaluated using antero-posterior and lateral radiograms of the treated humerus. Results The mean follow-up was 16.6 (range 12–28) months. The mean fixator time was 84 (range 63–118) days. The mean range of forward flexion, internal rotation, external rotation, and abduction were 145°, 61.2°, 65°, and 115°, respectively. The mean Constant, DASH, and VAS scores were 79.8, 10, and 1.75, respectively. Seven of the eight patients (87.5 %) healed radiologically. Two complications were observed in two patients: non-union and superficial pin site infection. Conclusions In the treatment of unusual, comminuted proximal diaphyseal humeral fractures, CREF using a hybrid-type EF is a minimally invasive, advantageous procedure with acceptable rates of healing, low risk of surgical site infection, and early range of motion. Level of evidence Level IV, case series.
