Abstract

PURPOSE
In arthroscopic rotator cuff repair, the crucial step is secure fixation of Anchor to bone. However, osteoporosis of the tuberosity is frequently encountered in old patients, and can cause insecure fixation of anchors. The Aim of our study was to introduce a technique for anchor hole augmentation with bone cement when fixation failure of an anchor occurs, and to investigate the outcome.
MATERIALS AND METHODS
Among 223 rotator cuff repairs performed between 2005 and 2009, anchor hole augmentation with polymethylmethacrylate was performed in 15 cases (all females; mean age of 65 years: range 49~77). Bone cement was injected into the anchor hole in a thick fluid state and the procedure was repeated to make a pot-like cement mantle. The anchor was inserted into the cement mantle while the cement hardened. The outcome was investigated, on average, at 16 months (6~32).
RESULTS
Radiographs showed cystic changes of the tuberosity. On follow-up radiographs and MRI, a change in the cement mantle was not noted. The final average UCLA score was 31 (28~35); 6 had excellent, 8 good and 1 fair results (p=0.008). Age-sex matched Constants score was 90 (74~98) (p=0.008).
CONCLUSION
Anchor hole augmentation with bone cement is useful when fixation failure of an anchor is encountered due to bone atrophy. Anchor hole augmentation with bone cement does not negatively influence the outcome.
