In recent studies objective evaluations have demonstrated that arthroscopic rotator cuff repairs can have higher failure rates than open repairs. Thus, there is a need for a stronger tissue-holding stitch for arthroscopical repair. The purpose of this study was to compare the biomechanical properties of traditional open transosseous suture technique and modified Mason-Allen stitches versus double-loaded suture anchors and arthroscopic Mason-Allen stitches in rotator cuff repair. Methods. In 20 sheep shoulders the infraspinatus tendons were dissected from their insertion and were randomized to 2 repair groups: (1) repair with transosseous suture and modified Mason-Allen stitches, (2) repair with double loaded bioabsorbable suture anchors and arthroscopic Mason-Allen stitches: Both groups were coupled with braided, nonabsorbable polyester (Ethibond) suture sized USP No. 2. All repairs were cyclically loaded from 10 to 180 N with the use of a materials testing machine. The number of cycles to gap formation of 5 and 10 rum at the repair site and the mode of failure were recorded. Results. The number of cycles to 5-mm gap was mean 634 (SD 106) for group 1 and mean 750 (SD 107) for group 2 (P < 0.026). The corresponding values to 10-mm, gap were mean 1573 (SD 161) for group 1, and mean 1789 (SD 183 cycles) for group 2 (P < 0.012). In group 2 the mode of failure occurred by tissue pull-out, whereas in group 1 the failure occurred by a mixture of suture breakage and pull-out. Conclusions. This time-zero study demonstrates that the combination of bioabsorbable suture anchors and arthroscopic Mason-Allen stitches provides strength superior to that of the modified Mason-Allen transosseous suture technique under isometric cyclic loading conditions. However, additional evaluation is needed to examine the effects on the sustained strength of the repair throughout the healing process. (c) 2006 Elsevier Ltd.

For that, most patients are unwilling to tolerate painful restriction while awaiting resolution. We prospectively investigated 30 patients (16 women, 14 men) for the outcome of arthroscopic capsular release in idiopathic frozen shoulder. Results were determined by the assessment of subjective and objective parameters to estimate both shoulder function and general health status. Symptoms persisted without improvement for a minimum of 6 months of conservative treatment. Preoperative average American shoulder and elbow surgeons score (ASES) was 35, visual analog scale (VAS) to measure pain was 7, and simple shoulder test (SST) was 4. Mean scores of the physical component of SF-36 were considerably reduced. Mean forward elevation was 85 degrees, average abduction was 70 degrees, mean internal rotation was 15 degrees, and mean external rotation was 10 degrees. Patients were followed-up at 6 weeks, 3, 6, 12 months and by a mean of 36 months. Range of motion for all planes improved (P < 0.05). Median VAS reduced to 2, average ASES increased to 91, and SST enhanced to a mean of 10 (P < 0.05). We stated improvement of the physical components in the SF-36 questionnaire in particular bodily pain and the role-physical score. There were no significant differences between the measurements in the early postoperative phase compared to the mid-term follow-up (P > 0.05). Our results demonstrate that arthroscopic release of refractory idiopathic frozen shoulder combined with a gentle manipulation provides reliable expectations for improvement in both clinical and general health status for most patients.

Methods: Eighteen mature female sheep were randomly assigned to either a single-row treatment group using arthroscopic Mason-Allen stitches or a double-row treatment group using a combination of arthroscopic Mason-Allen and mattress stitches. Each group was analyzed at 1 of 3 survival points (6 weeks, 12 weeks, and 26 weeks). We evaluated the integrity of the cuff repair using MRI and biomechanical properties using a mechanical testing machine. Results: The mean load to failure was significantly higher in the double-row group compared with the single-row group at 6 and 12 weeks (P = .018 and P = .002, respectively). At 26 weeks, the differences were not statistically significant (P = .080). However, the double-row group achieved a mean load to failure similar to that of a healthy infraspinatus tendon, whereas the single-row group reached only 70% of the load of a healthy infraspinatus tendon. No significant morphologic differences were observed based on the MRI results. Conclusions: This study confirms that in an acute repair model, double-row repair may enhance the speed of mechanical recovery of the tendon-bone complex when compared with single-row repair in the early postoperative period.

In selected patients, knee arthrodesis is a well-recognized salvage procedure after infected TKA. The authors retrospectively reviewed their experience with this treatment option, presenting 20 patients (8 women, 12 men), performed between 1990 and 2002. The average age was 67 years (range: 47-81 years) and the mean number of previous surgical procedures was 6 (range: 4-11 procedures). There were multiple indications for knee arthrodesis, including extensive bone or soft tissue loss, poor bone stock, and recurring infections. One-stage fusion was done in 7 knees while, on the other 13, arthrodesis was performed as two-stage fusions. The average clinical follow-up was 4.5 years (range: 2-11 years). 18 of the 20 patients were interviewed and graded using the Visual Analogue Scale (VAS) for pain, the Short Form-36 Health Survey (SF-36), and the Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire that has knee-related quality of life items. According to the VAS, the mean intensity was 3.4 points. 6 (33%) of the patients had no difficulty with the knee and 9 (50%) of them had mild or moderate difficulty. The SF-36 scores were similar to those for normative data for patients after TKA, with only the social functioning, role emotional, and physical functioning scores being lower and the role physical and social functioning scores being higher. Three of 20 fusions failed, whereas two knees became non-infected non-unions. In one, the knee infection persisted and required above-knee amputation. The two-stage arthrodesis gave the most predictable rate of fusion. Persistent infection and extensive bone stock losses led to failure even under the best circumstances.

Methods: From 1997 to 2000, 27 patients (20 women, 7 men) had undergone arthroscopies because of poor results following total knee arthroplasty. Before the operation, the patients had suffered symptoms for an average of 11 months (range, 3 to 41 months). The average onset of symptoms after knee arthroplasty was 26 months (range, 3 to 59 months). The average patient age was 70 years (range, 42 to 81 years) and the average follow-up was 34 months (range, 24 to 52 months). At the initial operation, 19 patients had received total condylar surface replacement and 8 had received hemireplacement. Patients were evaluated using the Knee Society rating system. A review of the literature was performed by initial identification of the articles from a MEDLINE database followed by the use of cross references. Results: All of the patients were available for follow-up. Eighteen of the 27 procedures resulted in an improvement in the patient's knee score.
