All-Suture Repair for Compressive Rotator Cuff Tears: Reducing the Traction of the Tissue

Comparison of all-suture anchors with metallic anchors in arthroscopic cuff repair: Structural and functional properties and clinical suitability

Purpose

This study examined and compared all-suture anchors with metallic anchors in the arthroscopic repair of small to medium supraspinatus tears; a multi-dimensional evaluation protocol assessed (i) clinical, (ii) ultrasonographical, and (iii) functional criteria at mid-term.

Materials and methods

A sample of 40 patients, prescreened from a larger group who had undergone arthroscopic rotator cuff repair, were resolved into two groups of 20, based on the type of anchor used in their surgery (all-suture or metallic) and were evaluated postoperatively (mean = 44.3 months, SEM = 22.4 months, minimum period = 10.3 months). Clinical assessments included (i) objective and subjective scores (Constant, DASH, SPADI, SST), (ii) ultrasonographical examination, as well as (iii) isometric and isokinetic strength testing. Raw data from the operated side was compared with those from the contralateral side within each group. Raw data for the PROMs and for the US evaluation were compared between groups. Strength data, as well as the Constant score values, were further analyzed based on (i) the difference between operated and intact sides, as well as (ii) the strength ratio between operated and intact sides; the transformed data were then compared between the two groups.

Results

We found no statistically significant differences in any of the parameters considered between shoulders operated using ASAs or MAs, nor between operated and non-operated sides in each group.

Conclusion

Our findings indicate that the reliability and performance characteristics of all-suture anchors and metallic anchors are practically indistinguishable for arthroscopic treatment of small to medium lesions of the supraspinatus tendon.

SPSS Analysis of Pain Factors in Rotator Cuff Repair

In this study, the matched case-control study was used. Nineteen cases of severe pain in the early postoperative period among 55 patients were set as the observation group, and 57 cases of simultaneous rotator cuff repair without severe pain were matched in a 1 : 3 ratio as the control group. Patients’ general information, disease characteristics, anesthesia and analgesia scheme, and operation information were collected. Frequency statistics, Wilcoxon signed rank sum test, regulatory effect analysis, and Poisson regression analysis were performed on these data. Some findings are included in the analysis. (1) There was a markable difference of 0.01 between the preoperative 48 h maximum pain value and the postoperative 48 h maximum pain value in the observation group. (2) There was a markable difference of 0.01 between the size and shape of the wound tear and the maximum pain value at 48 h after operation in the observation group. (3) When the number of opioid use affected the maximum pain value at 48 h after operation, the regulatory variables (type, quantity, and number of days of postoperative analgesics) were at different levels, and the impact amplitude had markable differences. (4) Age has a markable negative impact on the postoperative hospital stay. (5) The operation duration has a markable positive relationship with the postoperative hospital stay. (6) The analgesic pump had a markable positive impact on the postoperative hospital stay. (7) The location of injury did not affect the postoperative hospital stay.
