Pain, range of motion, and function all significantly improved after arthroscopic rotator cuff repair using the suture-bridge technique, regardless of the presence of diabetes. However, sustained hyperglycemia increased the possibility of anatomic failure at the repaired cuff. In diabetic patients, an effective glycemic control was associated with better rate of healing after rotator cuff repair.

In approximately 80% of the intra-articular biceps tears evaluated in this study, a "hidden lesion" was observed going beyond the bicipital groove and extending to the distal extra-articular portion. Therefore, the subpectoral portion may be considered the optimal tenodesis site for the complete removal of all hidden biceps lesions.

Purpose Pre-and postoperative tibial posterior slope angles (PSAs) were assessed in patients who underwent cruciateretaining total knee arthroplasty (TKA). Material and methods A total of 386 cruciate retaining TKA were performed in 308 patients and retrospectively reviewed. Based on the prostheses, 202 cases using NexGen® were classified as group I, 120 cases using PFC sigma® as group II, and 64 cases using Vanguard® as group III. Postoperative PSA of groups I, II, and III were compared. Results In groups I, II, and III, postoperative PSA was 6.0˚, 6.0˚, and 4.5˚, respectively (p<0.001). Between preoperative measurement and final follow-up examination, mean knee score (59.7 to 97.3), function score (54.2 to 90.5), and range of motion (ROM; 126.7°to 132.2°) improved. These three values did not differ significantly among groups. Conclusions The 3°slope of the Vanguard® polyethylene insert caused the difference in PSAs. This design characteristic should be considered when using this implant in TKA.

Irrespective of involvement in the anterior attachment of the rotator cable, the mean 24-month follow-up demonstrated excellent pain relief and improvement in the ability to perform activities of daily living after arthroscopic rotator cuff repair. However, tears with anterior disruption of the rotator cable showed a significantly larger and more complex tear pattern and more advanced fatty degeneration. Additionally, the retear rate was significantly higher in patients with a tear involving the anterior attachment of the rotator cable.

The authors investigated the efficacy of antibiotic irrigation as the therapeutic option in congenital nasolacrimal duct obstruction. We retrospectively reviewed the medical record of 76 patients' eyes in whom congenital nasolacrimal duct obstruction had been diagnosed. In 50 of these patients, the colonizing microorganism was identified and, irrigation through canaliculi was performed using antibiotics of suitable sensitivity. Nasolacrimal system probing was performed on 26 patients as the control group. Treatment was regarded successful when over a 4 week period epiphora or mucous discharge disappeared and when saline passed without resistance on irrigation. 96.0% of patients in the irrigation group and 84.6% of patients in probing group were treated successfully. There was no statistical difference in the success rate between the two groups (P = 0.173). The recovery period based on culture results was 3.22 +/- 0.37 months in the group in which microorganisms were isolated and 2.39 +/- 0.35 months in the group in which no organisms were isolated. There were no statistically significant differences in the success rates between the group in which there was growth and the group in which there was no growth (P = 0.1308). Thus a similar result was obtained using nasolacrimal probing and canaliculus antibiotic irrigation in congenital nasolacrimal duct obstruction. Antibiotic irrigation is a safe and simple therapeutic option in congenital nasolacrimal duct obstruction.
