All-Arthroscopic Versus Mini-Open Single-Row Repair of Full-Thickness Rotator Cuff Tears: A Prospective Comparative Study
This prospective comparative study of 24 patients suggests that all-arthroscopic single-row repair of full-thickness rotator cuff tears yields superior early functional recovery, greater range of motion, and lower pain scores at six months compared to mini-open repair, though the findings are limited by the small sample size and short follow-up.

The human shoulder is a marvel of engineering, capable of moving in almost every direction, but this freedom comes at a cost: the muscles and tendons that stabilize the joint are prone to tearing. When a full-thickness tear occurs, meaning the tendon is completely severed from the bone, the shoulder often becomes painful and weak, making simple tasks like reaching overhead impossible. For decades, surgeons have debated the best way to fix these tears. One approach involves a "mini-open" technique, where a small incision is made to split the muscle fibers and access the damage directly. The other is an "all-arthroscopic" method, which uses tiny cameras and instruments inserted through small portals to repair the tendon without cutting through the muscle. While both methods are known to work, it has remained unclear if one offers a distinct advantage over the other, particularly in how quickly a patient recovers movement and how much pain they feel in the weeks following surgery.
In a recent study conducted at a teaching hospital in India, researchers set out to settle this question by comparing these two approaches head-to-head. They focused on a specific group of twenty-four patients who had suffered full-thickness rotator cuff tears. To ensure a fair comparison, the team kept the actual repair method identical for everyone: every patient received a single-row suture-anchor fixation, a technique where the tendon is secured to the bone using a single line of stitches anchored into the bone. The only variable that changed was the path the surgeon took to get there. Twelve patients underwent the all-arthroscopic repair, while the other twelve received the mini-open repair. The researchers then tracked these individuals closely over six months, measuring their shoulder movement, pain levels, and overall function at regular intervals.
The results painted a clear picture of early recovery. Both groups of patients improved significantly over time, regaining strength and mobility as their tendons healed. However, the group that received the all-arthroscopic repair showed a faster and more complete return to normal function. By the six-month mark, these patients could lift their arms higher, rotate them further, and move them in all directions with greater ease than those in the mini-open group. On standard scoring systems used to measure shoulder health, the all-arthroscopic group achieved higher marks, indicating better overall function. Perhaps most noticeably, these patients reported less pain throughout their recovery. While both groups started with similar levels of discomfort, the all-arthroscopic patients felt less pain as early as the first week after surgery, and this lower level of pain persisted through the six-month follow-up.
The study also looked at safety and complications. In the mini-open group, two patients experienced issues with their surgical wounds, one involving a superficial separation and another a deeper separation of the tissue. No such wound complications occurred in the all-arthroscopic group. While the difference in complication rates was not statistically large enough to be considered definitive proof due to the small number of participants, the absence of any wound issues in the all-arthroscopic group aligns with the theory that avoiding a larger incision and muscle splitting reduces trauma to the body. The researchers noted that the mini-open group had a slightly older average age and different injury causes compared to the all-arthroscopic group, which could have influenced the results, but the trend toward better early recovery in the arthroscopic group was consistent across the measurements.
Despite these promising findings, the authors are careful not to declare one method the absolute winner for every situation. The study involved a small number of patients and was not randomized, meaning the surgeons chose the technique based on their judgment and the patient's preference rather than a coin toss. This design, along with the relatively short six-month observation period, means the results should be viewed as a strong suggestion rather than a final verdict. The researchers emphasize that both techniques successfully repaired the tears and restored function, but the all-arthroscopic approach appeared to offer a smoother, less painful road to recovery in the short term. Until larger, more rigorous studies are conducted with longer follow-up periods, the choice between the two methods will likely remain a matter of individual patient needs and surgeon expertise, though this new evidence adds weight to the idea that the less invasive, camera-guided route may help patients get back to their lives a little sooner.
