POSTER ABSTRACTS - ISAKOS

prospectively with 151 patients having 1 year
subjective and 38 with objective follow-up at an
average of 586 days (range 342-2267 days). The
dependant variable was patient satisfaction with
outcome, graded ordinally on a 1-10 scale.
Independent variables included various
demographic, surgical, objective and subjective
parameters. Diagnoses included instability
(n=63), rotator cuff pathology (n=70) and
associated anterior labral pathology (n=54).
Multiple stepwise linear regression analysis was
utilized to determine multivariate predictors of
patient satisfaction .
Results: Worker’s compensation, re-injury status,
prior surgery and gender were significant for
patient satisfaction (p>0.05). For surgical
variables, there were significant differences in
patient satisfaction for a torn biceps, articular
cartilage pathology and use of thermal treatment
(p>0.05). For Objective variables, there were
significant differences in satisfaction for passive
forward elevation and pain with cross-armabduction
(p>0.05). For subjective variables, all
question regarding pain and function were
significant with satisfaction (p>0.05). ASES score,
painless use of arm, pain with daily activities or
recreation, returning to pre-injury competition
level and age are independent predictors of
patient satisfaction (R2=0.59).
Conclusion: Univariate and multivariate
determinants of patient satisfaction with outcome
after SLAP surgery were established. Some
specific surgical and objective variables were
associated with satisfaction. However, subjective
variables of pain and function had the most
robust associations with satisfaction . Thus, in
assessing the outcomes of SLAP surgery, we
would like to emphasize the importance of
patient-derived assessment of symptoms and
function.

Introduction: Total shoulder arthroplasty is mostly
successful, however several factors can be
involved in failure and poor clinical results. In this
study, we report our experience in shoulder
replacement arthroscopy trying to define its
diagnostic and therapeutic indications.
Materials and Methods: Between 1994 and 2000,
12 patients with painful shoulder replacement
underwent arthroscopy as a diagnostic or
therapeutic procedure (11 hemiarthroplasty, 1
total shoulder arthroplasty). Arthroscopy was
performed with an average of 28 months (6-36)
after arthroplasty. In this period all patients were
placed on a conservative program (home
exercises, outpatient physical therapy and
analgesic medication) in order to avoid surgery.
We used the Constant score for clinical evaluation
preoperatively and the last follow up (average 19
months, 6-72). X-rays and CT arthrogaphy were
performed before arthroscopy. Postoperatively,
rehabilitation program included early
mobilization in all cases.
Results: Arthroscopy established the etiologic
diagnosis in all cases. It was a therapeutic
procedure in 9 cases: 5 capsular release, 4 biceps
tenotomy, 2 loose bodies (cement) removal and 1
subacromial decompression. In 3 cases,
arthroscopy was not sufficient to treat the
problem. The first one needed a totalisation of the
hemiathroplasty because of important glenoid
cartilage damage. The second presented an
important cement bar not removable by
arthroscopy. In the third patient, we performed
open repair for a massive rotator cuff tear.
Postoperatively, the absolute Constant score
increased from 25 to 43 concerning the 9 patients
treated arthroscopically. Pain and shoulder
function were significantly improved but there was
no improvement in strength evaluation.
Conclusion: Arthroscopy for diagnostic or
therapeutic purposes in prosthetic shoulder
appears to be reliable, safe, worthwhile and
technically feasible. Although open revision of the
shoulder replacement is sometimes required,
arthroscopic management may be an effective
alternative in certain cases. Biceps tenotomy and
capsular release improve significantly pain and
stiffness.
