Arthroscopic decompression of calcific tendinitis without cuff repair.

Aims: The aim of this study was to investigate the outcomes of arthroscopic decompression of calcific tendinitis performed without repairing the rotator cuff defect. Methods: A total of 99 patients who underwent treatment between December 2013 and August 2019 were retrospectively reviewed. Visual analogue scale (VAS) and American Shoulder and Elbow Surgeons (ASES) scores were reviewed pre- and postoperatively according to the location, size, physical characteristics, and radiological features of the calcific deposits. Additionally, the influence of any residual calcific deposits shown on postoperative radiographs was explored. The healing rate of the unrepaired cuff defect was determined by reviewing the 29 patients who had follow-up MRIs. Results: Statistically significant improvement from pre- to postoperation was seen in all VAS and ASES scores for each group, but no statistical differences were seen between the postoperative scores according to the differences in the features of the calcific deposits. When residual calcification was observed postoperatively, the mean ASES and VAS (rest) scores improved significantly to 95.0 (SD 5.6) and 0.0 (SD 0.0), respectively (p = 0.006 and p < 0.001), and did not differ from those who had the complete removal. Of 29 patients who had follow-up MRIs, six (20.7%) showed signs of an interstitial tear. This group's mean postoperative ASES and VAS (rest) scores improved to excellent levels of 96.0 (SD 3.7) and 0.0 (SD 0.0), respectively, and were similar to those of the 23 patients with normal MRI appearances. Conclusion: Arthroscopic removal of calcific deposits without repairing the rotator cuff defect resulted in significant improvement in function and pain level, regardless of the deposit's location, size, type, and whether or not complete excision was achieved. Despite leaving the defects unrepaired, in the limited number of patients with follow-up MRIs, 23 of 29 patients (79.3%) showed good healing, and the rest, who had persistent signs of interstitial defects on the MRIs, still had excellent outcomes. The removal of calcific deposits without repairing the cuff defects provided excellent outcomes.

Comparing effectiveness of polydeoxyribonucleotide injection and corticosteroid injection in plantar fasciitis treatment: A prospective randomized clinical study.

BACKGROUND: This study aimed to compare the efficacy and safety of polydeoxyribonucleotide (PDRN) injection and corticosteroid injection for plantar fasciitis. METHODS: This study included 44 patients with plantar fasciitis, randomly allocated to the PDRN and corticosteroid groups. Evaluation using the visual analogue scale (VAS) pain score and Manchester-Oxford foot questionnaire (MOXFQ) was conducted at baseline, 1, 2, 6weeks and 6months. The thickness and echogenicity of the plantar fascia in ultrasonography and complications were recorded. RESULTS: Corticosteroid injection elicited more pain relief than did PDRN injection at 2 (p=0.010) and 6weeks (p=0.016); however, it showed no superiority at 6months (p=0.523). MOXFQ showed similar outcomes. The thickness and echogenicity did not differ between groups and no complications were reported in either group. CONCLUSIONS: We demonstrated that PDRN injection could be an effective and safe option for plantar fasciitis and was comparable to corticosteroid injection after 6months follow up. LEVEL OF EVIDENCE: II, comparative study.
