Do Knots Matter in Superior Labrum Anterior to Posterior Lesions Repair?

BACKGROUND: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a “knot-ache”. This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. METHODS: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. RESULTS: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. CONCLUSIONS: The knots of suture anchor maybe a possible etiology of the pain, which we termed a “knot-ache”. Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, “knot-ache”. Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

Effectiveness of Selective Nerve Root Block on the Need for Surgical Treatment of Patients with Cervical Radicular Pain: A Minimum 5 Years Follow-Up / 대한정형외과학회잡지

PURPOSE: The purpose of this study is to assess the 5-year outcome of patients considering surgery for complaint of cervical and radiating pain treated by selective nerve root block (SNRB). MATERIALS AND METHODS: Between January 2001 and December 2007, 39 cases were selected from patients who underwent SNRB before the operation and were followed-up for more than five years. The mean follow-up period was 64.3 months and the mean age was 57.7 years. The patients were divided into the operation group and the only cervical SNRB group. The groups were compared for gender, age, duration, disease, single or multi-level, and root compression rate on magnetic resonance imaging. The clinical results were analyzed using the neck disability index (NDI) and the visual analogue scale (VAS) score. RESULTS: Among the 39 cases scheduled for the operation, 20 cases (51.3%) did not proceed to the operation and 13 cases among them were treated with additional conservative treatment. The average VAS score for the operation group and the cervical SNRB group was 8.1 points and 7.5 points at the preoperative state and the pre-injection state. After surgical treatment and cervical nerve root block, the scores were 3.0 points for all. The NDI for the operation group was 11.3 points at the last follow-up. The NDI for the cervical nerve root block group was 13.6 at the last follow-up. There was no significant difference between the two groups. Shorter duration and younger age tended to show a higher operation rate. At the last follow-up, 7 cases (17.9%) after cervical SNRB had persistent symptom relief without other treatment. CONCLUSION: Cervical SNRB is considered an effective treatment for patients with cervical disease with radiating pain and who are scheduled for an operation.
