BACKGROUND: To report the results of an arthroscopic percutaneous repair technique for partial-thickness tears of the anterosuperior cuff combined with a biceps lesion. METHODS: The inclusion criteria were evidence of the upper subscapularis tendon tear and an articular side partial-thickness tear of the supraspinatus tendon, degeneration of the biceps long head or degenerative superior labrum anterior-posterior, above lesions treated by arthroscopic percutaneous repair, and follow-up duration > 24 months after the operation. American Shoulder and Elbow Surgeons (ASES) score, constant score, the pain level on a visual analogue scale, ranges of motion and strength were assessed. RESULTS: The mean (+/- standard deviation) age of the 20 enrolled patients was 56.0 +/- 7.7 years. The forward flexion strength increased from 26.3 +/- 6.7 Nm preoperatively to 38.9 +/- 5.1 Nm at final follow-up. External and internal rotation strength was also significantly increased (14.2 +/- 1.7 to 19.1 +/- 3.03 Nm, 12.3 +/- 3.2 to 18.1 +/- 2.8 Nm, respectively). Significant improvement was observed in ASES and constant scores at 3 months, 1 year and the time of final follow-up when compared with preoperative scores (p < 0.001). The mean subjective shoulder value was 86% (range, 78% to 97%). CONCLUSIONS: The implementation of complete rotator cuff repair with concomitant tenodesis of the biceps long head using arthroscopic percutaneous repair achieved full recovery of normal rotator cuff function, maximum therapeutic efficacy, and patient satisfaction.

OBJECTIVE: To describe the magnetic resonance (MR) appearance of intact posterior cruciate ligament (PCL) grafts. MATERIALS AND METHODS: Thirty-one postoperative MR examinations were performed in 21 grafts of 20 patients after PCL reconstruction. All 21 grafts were proven to be intact on second-look arthroscopic examination. Two musculoskeletal radiologists retrospectively analyzed the MR findings and reached decisions by consensus. The signal intensity (SI) of the graft on proton density-weighted and T2-weighted images, as well as the shapes, locations, and segments of increased SI were recorded. The graft thickness was also recorded and correlated to elapsed time since reconstructive surgery. RESULTS: The SI of the graft was high (15/31, 48%), intermediate (10/31, 32%), or low (6/31, 19%) on proton density-weighted images, and high (9/31, 29%), intermediate (6/31, 19%), or low (16/31, 52%) on T2-weighted images. The graft SI decreased significantly as postoperative time elapsed. The shape of the increased SI within the grafts was band-like (14/25, 56%) or focal (11/25, 44%). The increased SI was located in the proximal (18/25, 72%), middle (21/25, 82%), and distal (12/25, 48%) segments. In the axial plane, the location of increased SI was intrasubstance (19/25, 76%) or peripheral (10/25, 40%). A 'focal' shape of increased SI was found significantly more in Achilles tendon allografts, while a band-like shape was more frequent in autogenous double-loop hamstring tendon grafts. Graft thickness ranged from 5-15 mm. The difference in graft thickness relative to postoperative time was not statistically significant (p = 0.79). CONCLUSION: Stable PCL grafts commonly showed an increased SI at any segment or location, even though they were stable. The shape of increased SI differed according to allograft donor sites. However, SI tended to decrease as time elapsed.

The common causes of rhabdomyolysis include trauma, hypoxia, drugs, toxins, infections and hyperthermia. Operative insults, including direct trauma and ischemia, have the potential to cause the development of rhabdomyolysis. Pneumatic tourniquets used during arthroscopic knee surgery to prevent blood loss have led to many complications such as nerve paralysis and vascular injuries. Rhabdomyolysis can also be caused by prolonged pneumatic tourniquet application without a midapplication release, and also from an increased application pressure, but the actual incidence of this is low. In order to prevent rhabdomyolysis, the clinicians must be aware of such risks and follow strict guidelines for the application time, the midapplication release and also the inflation pressure. Vigorous hydration and postoperative patient surveillance are helpful to prevent rhabdomyolysis. We have recently experienced a case of rhabdomyolysis after the arthroscopic knee surgery, and the rhabdomyolysis could have been associated with the use of a pneumatic tourniquet.
