Follow up:
mean 34 months
Only patients with intact rotator cuff
were included
For both TSA and HA the differences
in ASES score and in UCLAS score
between preoperative and follow-up
status were statistically significant
(p < 0.001)
Follow up:
2 years
Only patients with intact rotator cuff
included
For both TSA and HA the difference in
Constant score between preoperative
and follow-up status was statistically
significant (p < 0.001)
Follow-up:
12 months
The HA-group had a significantly
better total Constant score
preoperatively compared to the TSAgroup
