Clinical and ultrasound results after arthroscopic repair of the rotator cuff

The literature reports good functional results obtained with arthroscopic repair of the rotator cuff, but the incidence of anatomical healing has not been sufficiently studied. Ultrasound examination makes it possible to accurately document the healing process of the tendon at the bone, gathering information that may be useful in a comparison with clinical data. A total of 43 consecutive arthroscopic repairs of rotator cuff injuries were considered, that had made use of anchors and non-resorbable suturing. A total of 42 patients were willing to undergo clinical monitoring with an associated ultrasound examination after 3, 6 and 12 months. When ultrasound examination after 6 and 12 months was carried out, 36 patients presented with anatomical healing of the rotator cuff. The total percentage of repair failures was 14.3% and increased to 23% if we take into consideration the subscapular tendon alone. Constant score went from a preoperative mean of 51.25 to a mean of 78.21 after 12 months (p<0.001). Arthroscopic repair of the rotator cuff leads to anatomical healing of the tendons in a high percentage of cases, obtaining good functional results. The absence of healing is associated with lower values for recovery of strength at clinical follow-up. The advanced age of the patients (p<0.001) and the extensive injuries that involve several tendons (p=0.002) are negative prognostic factors.
