Total Healing of a Partial Rupture of the Supraspinatus Tendon Using Barbotage Technique Associated with Platelet-Rich Plasma: A Randomized, Controlled, and Double-Blind Clinical Trial.

The prevalence of partial rotator cuff tears (PRCTs) is high in the general population. Our hypothesis is that barbotage, when associated with platelet-rich plasma (PRP), is an effective method for healing these tears. The aim of this study was to compare the effects of barbotage with or without PRP on the healing of partial supraspinatus tendon tears (PSTTs). This study assessed the Western Ontario Rotator Cuff Index score and ultrasound (US) images at 6 weeks and 6 months after treatment. Patients in both groups showed clinical improvement, with no significant difference in scores at 6 weeks. However, at 6 months, the PRP group exhibited significant improvement (p = 0.019). Both groups experienced a reduction in ST tear size, but the PRP group demonstrated a significant enhancement at 6 weeks and 6 months. In conclusion, the US-guided barbotage technique, whether associated with PRP or saline solution, proved to be an effective treatment for clinical improvement and reduction in the size of PSTT. Better clinical improvement results were observed with PRP at 6 months. The combination of PRP with barbotage was superior in reducing the size of the ST tear at both 6 weeks and 6 months, resulting in complete healing in 79.3% of the tears.

EVALUATION OF THE RESULTS OF ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION USING FLEXOR TENDONS AND RIGID GUIDE TRANSVERSE SCREW.

OBJECTIVE: The aim of this study was to analyze the results of ACL (anterior cruciate ligament) reconstruction using quadruple flexor tendons as grafts, with ligament fixation in the femur using a rigid guide transverse screw and in the tibia, using a cancellous screw with a fixing washer. METHODS: 173 knees (166 from males and seven from females) that had undergone surgery with ACL reconstruction using this technique between December 2002 and February 2007 were evaluated. The mean age was 30 years (from 13 to 56 years), and the mean follow-up time was 30 months (6-55 months). We divided the knees into three groups, which were assessed using the Lysholm scale: Group A with six months of follow-up; Group B with 12 months of follow-up; and Group C with 24 months of follow-up. RESULTS: We evaluated the results, and groups A, B and C received 94, 95 and 95 points respectively on the Lysholm scale. CONCLUSIONS: The surgical technique proved to be safe and easy to perform, with good results and a low complication rate. Also, its results were maintained throughout the study period of 24 months.
