Combination of TowerLike ZnO Nanostructures and Its To prevent Properties
The response rate was 28 out of 55 (51%) and the median time to follow-up was 101(IQR 88.5-131.8) months. The median satisfaction score for treatment results was 8.5 out of 10 (IQR 6-10). FAOS symptoms 84.5 (IQR 58.0-96.4), FAOS pain 90.3 (IQR 45.1-100.0), FAOS ADL 94.9 (IQR 58.1-100.0), FAOS sport 90.0 (IQR 36.3-100.0) and FAOS QOL 71.9 (IQR 37.5-93.8) and median AOFAS was 100 (IQR 89-100). The median PLL difference between before operation and 2weeks after the operation was -4mm (IQR-6 and -1) and the median PLL difference between 2weeks after the operation and at follow-up was 1mm (0-2). The median PFA was 65 (63-69) at baseline, 66.5 (60.8-70.3) 2weeks after the operation and 64 (60.8-65.3) at follow-up.
Despite the limited response rate, this study shows high patient satisfaction and good long-term functional outcome in patients affected by retrocalcaneal bursitis who underwent endoscopic calcaneoplasty.

Anterolateral rotatory instability (ALRI) may result from isolated ruptures of the anterior cruciate ligament (ACL) or combined lesions with the anterolateral ligament (ALL). Biomechanical studies have demonstrated that the ALL contributes to the overall rotational stability of the knee. The purpose of this study was to investigate the biomechanical function of anatomic ALL reconstruction (ALL
) in the setting of a combined ACL and ALL injury and reconstruction. The hypothesis was that combined ACL reconstruction (ACL
) and ALL
(ACL/ALL
) significantly reduces internal rotation and shows load sharing between both reconstructions compared with isolated ACL
.
Eight fresh-frozen cadaveric knees were evaluated using a six degrees of freedom knee simulator. Continuous passive motion and external loads were tested. Kinematic differences between ACL
and combined ACL/ALL
were compared. find more Additionally, ACL graft tension and ALL graft strain were measured continuously throughout the testing protocol.
Combevertheless, additional ALLrec with fixation at 60° and with low tension could not restore extension-near rotatory stability. For that reason, ALLrec with fixation at 60° flexion cannot be recommended in clinical application.
It is generally agreed that surgical treatment is warranted for acute posterior cruciate ligament (PCL) avulsion fracture with displacement. However, the amount of displacement that warrants surgical treatment has not been defined. The purpose of this study was to determine the optimal cut-off value for displacement of posterior cruciate ligament avulsion fracture in determining non-operative treatment and to compare the results of non-operative treatment in acute isolated PCL avulsion fractures with non-operative treatment of acute PCL injury.
Between 2007 and 2017, 30 consecutive patients with acute isolated PCL avulsion fractures and 70 consecutive patients with acute isolated PCL injuries, all of whom underwent non-operative treatment (cast immobilization with > 2years of follow-up) were retrospectively analyzed. Clinical scores including the International Knee Documentation Committee subjective score, Lysholm score, and Tegner activity score, as well as side-to-side differences on stress radiograpment in PCL avulsion fracture to predict failure of non-operative treatment was 6.7mm (AUROC = 1.0).
The outcomes of non-operative treatment of acute isolated PCL avulsion fractures were comparable to those of patients with acute isolated PCL injuries. Acute PCL avulsion injuries with displacement of less than 6.7mm should be considered for non-operative treatment.

To compare the clinical, radiological outcomes, economic and technical differences for ORIF by cancellous screw fixation versus ARIF by double-tunnel suture fixation for displaced tibial-side PCL avulsion fractures.
Forty patients with displaced tibial-sided PCL avulsions were operated upon after randomizing them into two groups (20 patients each in the open and arthroscopic group) and followed up prospectively. Assessment included duration of surgery, cost involved, pre- and post-operative functional scores, radiological assessment of union, and posterior laxity using stress radiography and complications.
The mean follow-up period was 33months (27-42) (open group) and 30months (26-44) (arthroscopic group). The duration of surgery was significantly larger in the arthroscopic group (47.8 ± 17.9min) as compared to the open group (33.4 ± 10.1min). The costs involved were significantly higher in the arthroscopic group (p- 0.01). At final follow-up, knee function in the form of IKDC (International Knee Documentation Committee) evaluation (89.9 ± 4.8-open and 89.3 ± 5.9-arthroscopic) and Lysholm scores (94.2 ± 4.1-open and 94.6 ± 4.1-arthroscopic) had improved significantly with the difference (n.s.) between the two groups. The mean posterior tibial displacement was 5.7 ± 1.8mm in the open group and 6.3 ± 3.1mm in the arthroscopic group which was (n.s.). There were two non-unions and one popliteal artery injury in the arthroscopic group.
Both ARIF and ORIF for PCL avulsion fractures yield good clinical and radiological outcomes. However, ORIF was better thanARIF in terms of cost, duration of surgery, and complications like non-union and iatrogenic vascular injury.

To evaluate the results of the remodified Mason-Allen suture technique concomitant with high tibial osteotomy (HTO) for medial meniscal posterior root tears (MMPRTs). The hypothesis was that this procedure would improve clinical results, prevent progression of knee osteoarthritis and increase the healing rate of the repaired root.
Total 17 patients of mean 51.5 ± 4.4years who were underwent this combined procedure for MMPRT completed this study. Lysholm and Hospital for Special Surgery (HSS) scores, Kellgren-Lawrence (KL) grade reflecting osteoarthritis progression were evaluated preoperatively and at the last follow-up. Medial meniscus extrusion (MME) was measured on magnetic resonance imaging preoperatively and at mean 26.1 ± 2.3months postoperatively. Second-look arthroscopy was performed at mean 25.1 ± 5.3months postoperatively. The healing status of the repaired root was classified as complete, partial and failed healing. The Outerbridge (OB) grade of the medial femoral condyle (MFC) was compared between index surgery and second-look arthroscopy.
