Infection, medical complications after surgery, and surgical complications requiring revision of implants are the primary causes of unplanned early readmissions and spine surgery. Further studies are necessary to identify patients and procedures most associated with readmission.
Background:
Double-row transosseous-equivalent (TOE) rotator cuff repair techniques have
been widely accepted because of their superior biomechanical properties when
compared with arthroscopic single-row repair. Concerns regarding repair
overtensioning with medial-row knot tying have led to increased interest in
knotless repair techniques; however, there is a paucity of clinical data to
guide the choice of technique.
Hypothesis:
Arthroscopic TOE repair techniques using knotless medial-row fixation will
demonstrate lower retear rates and greater improvements in the Constant
score relative to conventional knot-tying TOE techniques.
Study Design:
Systematic review; Level of evidence, 4.
Methods:
A systematic review of 3 databases (PubMed, Cochrane, and Embase) was
performed using PRISMA (Preferred Reporting Items for Systematic
Meta-Analyses) guidelines. Inclusion criteria were English-language studies
that examined repair integrity or Constant scores after arthroscopic rotator
cuff repair with TOE techniques. Two investigators independently screened
results for relevant articles. Data regarding the study design, surgical
technique, retear rate, and Constant shoulder score were extracted from
eligible studies. A quality assessment of all articles was performed using
the Methodological Index for Non-Randomized Studies (MINORS) criteria.
Results:
The systematic review identified a total of 32 studies (level of evidence,
1-4) that met inclusion and exclusion criteria. Of the 32 studies, 5
reported on knotless TOE techniques, 25 reported on knot-tying TOE
techniques, and 2 reported on both. In the knotless group, retear rates
ranged from 6% to 36%, and Constant scores ranged from 38-65 (preoperative)
to 73-83 (postoperative). In the knot-tying group, retear rates ranged from
0% to 48%, and Constant scores ranged from 42-64 (preoperative) to 55-96
(postoperative).
Conclusion:
Despite several theoretical advantages of knotless TOE repair, both knotless
and knot-tying techniques reported considerable improvement in functional
outcomes after rotator cuff repair. Although tendon failure rates showed a
downward trend in knotless studies, additional prospective studies are
warranted to better understand the role of medial-row fixation on tendon
repair integrity and postoperative clinical outcomes.
Water polo places significant stress on the hip joint requiring repetitive hip flexion and rotation to elevate the body out of water for passing, shooting and blocking. Femoroacetabular impingement (FAI) is common in water polo athletes; however, no study to date has investigated the results of hip arthroscopy in this patient population. The purpose of this study was to determine return to play rates and satisfaction following hip arthroscopy for FAI in a cohort of elite level water polo players. A retrospective review of our surgical database was performed. Collegiate water polo players with clinical and radiographic FAI who underwent hip arthroscopy were identified. Pre- and post-operative modified Harris hip scores (mHHSs) were obtained. Patient surveys were administered to determine return to play rates, level of return to play, timing of return and patient satisfaction. A Wilcoxon ranked sum test was performed to compare pre- and post-operative outcome scores. Ten patients met inclusion criteria. Average age was 19.5 years old (SD ±1.08). All patients were male Division 1 collegiate water polo players. Median mHHS improved from 66.0 (SD ±7.9) pre-operatively to 89.5 (SD ±3.2) at average 1.6 years (range: 0.4–3.6 years) post-operatively. Patient survey responses demonstrated a 100% return to water polo and 100% return to the same level of play (NCAA Division 1) at mean 5.75 months (SD ±1.8). All patients (10/10) reported being satisfied with their surgical result. Our study results, suggest that return to sport rates and patient satisfaction are high in water polo players who undergo hip arthroscopy for FAI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
