Context: It is common for swimmers to suffer shoulder injuries resulting in a wealth of research focusing on the causes and types of injury. However, there is a lack of evidence regarding current management for shoulder injuries in swimmers.

Aims: To investigate the diagnosis, subsequent management, and the return to swimming outcomes for swimmers presenting to an orthopedic practice.

Settings and design: Retrospective cohort study of competitive swimmers presenting to an orthopedic practice.

Materials and methods: The diagnosis, subsequent management, and the return to swimming outcomes were analyzed for 14 swimmers whose injuries were managed by a shoulder surgeon.

Statistical analysis used: Descriptive analysis.

Results: No significant association was identified between swimming stroke and type of injury. The majority of swimmers had good scapula rhythm, with no visible dyskinesis, including those with impingement. Swimmers with impingement did not require arthroscopy, and with nonoperative management had a mean time to return to swimming of 1.6 months. All labral tears required arthroscopic labral repair, with these swimmers having a mean time of 2.9 months postsurgery to return to swimming.

Conclusion: The study demonstrated that an accurate diagnosis, and appropriate choice of nonoperative and surgical treatments lead to reassuring outcomes for swimmers suffering from shoulder injuries.

Purpose: The 2-year outcomes of patients undergoing repair of triple labrum tears using an all-suture anchor device were assessed.

Materials and methods: Eighteen patients (17 male, one female; mean age 36.4 years, range: 14.2-62.3 years) with triple labrum tears underwent arthroscopic repair using the 1.4 mm JuggerKnot Soft Anchor (mean number of anchors 11.5, range: 9-19 anchors). Five patients had prior surgeries performed on their operative shoulder. Patients were followed for a mean of 2.0 years (range: 1.6-3.0 years). Constant-Murley shoulder score (CS) and Flexilevel scale of shoulder function (FLEX-SF) scores were measured, with preoperative and final postoperative mean scores compared with a paired Student's t-test (P < 0.05). Magnetic resonance imaging (MRI) was also performed at final postoperative.

Results: Overall total CS and FLEX-SF scores increased from 52.9 ± 20.4 to 84.3 ± 10.7 (P < 0.0001) and from 29.3 ± 4.7 to 42.0 ± 7.3 (P < 0.0001), respectively. When divided into two groups by whether or not glenohumeral arthrosis was present at the time of surgery (n = 9 each group), significant improvements in CS and FLEX-SF were obtained for both groups (P < 0.0015). There were no intraoperative complications. All patients, including contact athletes, returned to their preinjury level of sports activity and were satisfied. MRI evaluation revealed no instances of subchondral cyst formation or tunnel expansion. Anchor tracts appeared to heal with fibrous tissue, complete bony healing, or combined fibro-osseous healing.

Conclusion: Our results are encouraging, demonstrating a consistent healing of the anchor tunnels through arthroscopic treatment of complex labrum lesions with a completely suture-based implant. It further demonstrates a meaningful improvement in patient outcomes, a predictable return to activity, and a high rate of patient satisfaction.

Level of evidence: Level IV case series.

Aims: The aim was to evaluate the clinical and anatomic outcome of arthroscopic repair of type II SLAP lesions.

Materials and methods: The senior author performed isolated repairs of 25 type II SLAP lesions in 25 patients with a mean age of 40.0 ± 12 years. All tears were repaired using standard arthroscopic suture anchor repair to bone. All patients were reviewed using a standardized clinical examination by a blinded, independent observer, and using several shoulder outcome measures. Patients were evaluated by magnetic resonance imaging arthrogram at a minimum of 1-year postoperatively.

Statistical analysis used: Two-tailed paired t-test were used to determine significant differences in preoperative and postoperative clinical outcomes scores. In addition, a Fisher's exact test was used.

Results: At a mean follow-up of 54-month, the mean American Shoulder and Elbow Surgeons Shoulder Index (ASES) scores improved from 52.1 preoperatively to 86.1 postoperatively (P < 0.0001) and the Simple Shoulder Test (SST) scores from 7.7 to 10.6 (P < 0.0002). Twenty-two out of the 25 patients (88%) stated that they would have surgery again. Of the 21 patients who had postoperative magnetic resonance imaging arthrographys (MRAs), 9 patients (43%) demonstrated dye tracking between the labrum bone interface suggestive of a recurrent tear and 12 patients (57%) had a completely intact repair. There was no significant difference in ASES, SST, and patient satisfaction scores in patients with recurrent or intact repairs.

Conclusions: Arthroscopic repair of type II SLAP lesions demonstrated improvements in clinical outcomes. However, MRA imaging demonstrated 43% of patients with recurrent tears. MRA results do not necessarily correlate with clinical outcome.
