The treatment of massive rotator cuff tears remains controversial. There is lack of studies comparing patient-reported outcomes (PROM) of arthroscopic massive rotator cuff repairs (RCR) against large, medium and small RCRs. Our study aims to report the PROM for arthroscopic massive RCR versus non-massive RCR.

Patients undergoing an arthroscopic RCR under a single surgeon over a 5-year period were included. Demographic data were recorded. Pre-operative Quick-DASH and Oxford Shoulder Score (OSS) were prospectively collected pre-operatively and at final review (mean of 18 months post-operatively). The scores were compared to a matched cohort of patients who had large, medium or small RCRs. A post-hoc power analysis confirmed 98% power was achieved.

82 patients were included in the study. 42 (51%) patients underwent massive RCR. The mean age of patients undergoing massive RCR was 59.7 and 55% (n=23) were female. 21% of massive RCRs had biceps augmentation. Quick-DASH improved significantly from a mean of 46.1 pre-operatively to 15.6 at final follow-up for massive RCRs (p<0.001). OSS improved significantly from a mean of 26.9 pre-operatively to 41.4 at final follow up for massive RCRs (p<0.001). There was no significant difference in the final Quick-DASH and OSS scores for massive and non-massive RCRs (p=0.35 and p=0.45 respectively). No revision surgery was required within the minimum one year follow up timescale.

Arthroscopic massive rotator cuff repairs have no functional difference to non-massive rotator cuff repairs in the short term follow up period and should be considered in appropriate patient groups.

Background. The functional outcome and risk of recurrence following arthroscopic stabilisation for recurrent anterior shoulder instability is poorly defined in large prospective outcome studies. This is the first study to prospectively evaluate these outcomes in patients who have been treated using this technique. Methods. We performed a prospective study of a consecutive series of 302 patients (265 men and 37 women, mean age 26.4 years) who underwent 311 (9 bilateral) arthroscopic Bankart repairs for recurrent anterior instability. Patients were evaluated preoperatively and postoperatively at 6 months, and annually thereafter. The chief outcome measures were risk of recurrence and the two-year functional outcomes (assessed using the WOSI and DASH scores). Results. On survival analysis, the overall re-dislocation rate after surgery was 13.5% (42/311 shoulders). The median time to recurrence was 12 months (range 3 to 110 months) and 55% of these developed recurrent instability within 1 year of their surgery. The median follow-up in those patients who did not re-dislocate was 70 months. There was a significant improvement in the WOSI and DASH scores at 2 years postoperatively of 21.4 and 9.9 points respectively (both p<0.001). The risk of redislocation was significantly increased by the presence of glenoid bone loss associated with or without a Hill-Sachs lesion, and the type and engagement of a Hill-Sachs lesion on arthroscopic examination (all p<0.001). However, the risk in these sub-groups was lower than that reported in previous studies. A multivariate model was produced from these parameters to estimate the risk of recurrence at the time of primary surgery. Conclusions. The majority of patients have successful functional outcomes and relatively low risk of recurrence following arthroscopic stabilisation. The identification of preoperative factors which increase the risk of instability has enabled us to better counsel patients of their risk of failure following arthroscopic repair

Introduction. Interest in platelet-derived growth factors has been increasing as an adjunct in surgical techniques for tissue repair. Its use in ligament injuries repair has been studied mainly in animals. The authors intend to study growth factors influence in ACL repair using BTB graft. Material. 20 individuals underwent ACL rupture BTB arthroscopic repair, using Double Incision Mini-Invasive Technique. MRI (3-Tesla) images. GPSIII ® System to obtain Platelet-Rich Plasma (PRP) thrombin activated. Methods. Prospective study consisting of 2 groups of 10 patients each. Surgical technique, fixation method and postoperative protocol were the same. In the study group (SG-10 patients) graft was imbued with PRP and the remaing plasma was intra-articularly injected. The MRIs took place 6 weeks and 6 months after the procedure with and without gadolinium-DTPA enhancement. Evaluation was performed blindly by independent radiologists concerning femoral tunnel integration, sinovialization process and nonspecific synovitis. Clinical and functional status evaluation: IKDC. Statistical analysis in SPSS®. Results. Radiological evaluation was similar in both groups. In the Study Group at 6 weeks we verified less joint effusion and synovitis. At 6 months: no diference in integration in femoral tunnel, and in granulation tissue around the femoral tunnel in graft sinovialization. IKDC (mean ± SD) with PRP: pre-operative −45,66 ±6,98, post-operative −94,35 ±3,54 (Age-29 ± 10), without PRP: preoperative −48,02 ±12,68, post-operative −91,7 ±6,99 (Age −31 ±10). There are no statistical differences between the groups with and without PRP in clinical and functional assessments and MRI images. Discussion. The use of technology to accelerate and improve the processes of tissue repair and integration is of great interest in repairing the ACL. Studies in humans are rare, with low level of evidence and contradictory results. Although the limitations of this study, it seems to us that the use of growth factors has no advantages in the process of PT graft integration at 6 months. Conclusion. PRP doesn't seem to contribute to enhancement of the ligamentation process and articular rehabilitation when used as a step of BTB technique

Aims

In order to determine whether and for whom serial radiological evaluation is necessary in one-part proximal humerus fractures, we set out to describe the clinical history and predictors of secondary displacement in patients sustaining these injuries.
