6%) at ≥1 year after surgery. Compared with preoperative PROMIS scores, CD patients had significant postoperative improvements at 6 months and ≥1 year in mean PROMIS UE (26.7 vs 35.5 vs 38.9; P < .001) and PROMIS PI (67.6 vs 56.7 vs 56.4; P < .001). NCD patients had similar postoperative improvements at 6 months and ≥1 year in mean PROMIS UE (30.8 vs 38.6 vs 46.9; P < .001) and PROMIS PI (61.7 vs 53.0 vs 47.6; P < .001). The improvement in PROMIS scores was similar for the CD and NCD groups in both PROMIS UE (12.2 vs 16.1, respectively) and PROMIS PI (-11.2 vs-14.1, respectively).

Despite starting with worse PROMIS UE and PROMIS PI scores, patients undergoing RCR with symptoms of CD experienced significant improvement in function, pain, and depressive symptoms. Phycocyanobilin compound library chemical Preoperative depression should not be a contraindication to arthroscopic RCR in patients who are otherwise appropriate operative candidates.

We sought to determine the rate of intraoperative and early postoperative (90-day) complications of multiligamentous knee reconstruction surgeries, both medical and surgical, and associated variables from the 15-year experience of a single academic institution.

Patients treated at a single academic institution between 2005 and 2019 who underwent multiligament knee surgery were identified. Inclusion criteria included intervention with 2+ ligament reconstructions performed concurrently, and more than 90 days postoperative follow-up. Exclusion criteria included revision ligamentous knee surgery. Patient demographics, mechanism of injury, and associated injuries of patients withintraoperative and postoperative complications, time from injury to multiligamentous knee reconstruction, and surgical data, including tourniquet time, procedure time, and type of procedures performed were retrospectively recorded.

301 knees in 296 patients met the eligibility criteria. There were 11 intraoperative complications in 9ate with multiligamentous knee surgery. Surgeons should be wary of the increased intraoperative and postoperative complications associated with longer procedure times, inside-out meniscal repair, tibia-based PLC reconstruction, PCL reconstruction, and shorter time to surgery.

The goal of this study was to investigate trends in the United States for arthroscopic subacromial decompression (aSAD) and open SAD (oSAD) with and without rotator cuff repair (RCR) between 2010 and2018.

The PearlDiver Mariner claims database was queried using CPT codes for open and arthroscopic subacromial decompression and rotator cuff repair. Patient cohorts were developed for those undergoing aSAD or oSAD between 2010 and 2018, then segmented by whether RCR was performed simultaneously. Annual incidence was analyzed, as were associated diagnosis codes, and concomitant shoulder-associated procedures performed on the same day.

The PearlDiver Mariner dataset from 2010 to 2018 included 186,932 patients that underwent aSAD, while 9,263 patients underwent oSAD. The total incidence of aSAD declined from 118.0 to 71.3 per 100,000 (39.6% decrease) (P < .001). This change was due primarily to a decreasing incidence of aSAD performed without RCR, which declined from 66.3 to 25.5 per 100,000 (61.5% decrease) (P < .001). During the same period, the incidence of aSAD combined with RCR remained relatively stable, from 51.7 to 45.8 per 100,000 (11.5% decrease) (P= .27). The overall incidence of oSAD declined from 7.1 to 2.2 per 100,000 (68.1% decrease) (P < .001).

The overall rate of aSAD has declined in recent years, primarily due to a large decrease in the incidence of aSAD without RCR as an isolated treatment for rotator cuff disorders.

Prior studies have demonstrated a rising incidence of SAD; however, high-level clinical evidence and clinical practice guidelines have challenged its efficacy. It is important for orthopaedic surgeons to understand evolving national trends in management among their peers.

To systematically review the literature to (1) describe arthroscopic subscapularis repair constructs and outcomes in patients with isolated and combined subscapularis tears and (2) compare outcomes after single- and double-row subscapularis repair in both of these settings.

A systematic review was performed using PRISMA guidelines. PubMed, SCOPUS, and Cochrane Central Register of Controlled Trials were searched for Level I-IV evidence studies that investigated outcomes after arthroscopic subscapularis repair for the treatment of isolated subscapularis tears or subscapularis tears combined with posterosuperior rotator cuff tears in adult human patients. Data recorded included study demographics, repair construct, shoulder-specific outcome measures, and subscapularis retears. Study methodological quality was analyzed using the MINORS score. Heterogeneity and low levels of evidence precluded meta-analysis.

The initial search yielded 811 articles (318 duplicates, 493 screened, 67 full-text review). Forty-thher tears were isolated or combined or if repairs were single or double row.

The goal of the present study was to evaluate a potential tunnel convergence in combined anterior cruciate ligament (ACL) reconstruction using the anteromedial portal technique and lateral extra-articular tenodesis (LET).

Ten fresh frozen femora were dissected and a K-wires were inserted into the middle of the ACL stump, according to an ACL reconstruction at 110° and 140° knee flexion. ACL reconstruction at 120° and 130° was simulated. Seven K-wires with different femoral insertion sites and angulations were drilled into the lateral femoral condyle relative to the lateral epicondyle (E3 8 mm proximal and 4 mm posterior; E1 5 mm proximal and 5 mm anterior and E2 over-the-top position). Tunnel conflict rate was evaluated using a measuring arm and a metrology software.

Drilling the femoral ACL tunnel in low knee flexion (110°-120°) significantly (P < .001) reduced the tunnel conflict rate compared to the ACL drilled in high knee flexion (130°-140°). Changing the insertion point from proximal and posterid reliably avoid a tunnel conflict when the ACL was drilled between 110 and 130° using a low anteromedial portal.

The purpose of this study was to evaluate the short-term patient-reported outcomes of superior capsular reconstruction (SCR) and identify factors contributing to the success or failure of the procedure at 2 years.

A retrospective review was performed on data prospectively collected from the Surgical Outcomes System database. Patient-reported outcomes (PROMs) including American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, visual analog scale for pain, and Veterans RAND 12-Item Health Survey (VR-12) were evaluated at a minimum of 2 years postoperatively and reported using a minimal clinically important difference (MCID) and the percent of maximal possible improvement (MPI). In addition, preoperative and intraoperative variables were evaluated in patients with and without a postoperative improvement in ASES and SANE scores meeting the threshold of MCID.

Two-year follow-up data were available for 350 patients. Statistically significant improvements were noted in all PROMs at 2-year follow-up. In total, 240 patients (68.8%) achieved an MCID improvement of >17.5 in ASES score, and 185 patients (52.9%) achieved an MCID of >29.8 improvement in the SANE score. Primary SCRs were associated with a higher MPI in the ASES score (60.1% ± 39.8% vs 40.4% ± 47.9%; P= .025) and VR-12 physical score (14.0% ± 13.8% vs 8.0% ± 14.7%; P= .028) compared to revision repairs. Only diabetes was identified as a predictor of SANE score improvement (64.5% vs 62.2%; P= .041).

SCR is associated with improvement in patient-reported outcomes at short-term follow-up, with 53% to 69% of patients achieving an improvement considered to meet the MCID. Greater improvement is expected when SCR is performed as a primary procedure rather than as a revision procedure for failed rotator cuff repair.

To evaluate the effect of the Nonoperative Instability Severity Index Score (NISIS) criteria on an established US-geographic population-based cohort of patients with anterior shoulder instability.

An established geographically based medical record system was used to identify patients <40 years of age with anterior shoulder instability between 1994 and 2016. Medical records were reviewed to obtain patient demographics and instability characteristics. Patient-specific risk factors were individually incorporated into the 10-point NISIS criteria age (>15 years), bone loss, type of instability (dislocation vs subluxation), type of sport (collision vs noncollision), male sex, and dominant arm involvement. High risk was considered a score of ≥7 points and low risk as <7 points. Failure was defined as either progression to surgery or recurrent instability diagnosed by a consulting physician at any point after initial consultation.

The study population consisted of 405 patients with a mean follow-up timI, retrospective observation trial.

We sought to examine superior capsular reconstruction (SCR) outcomes after minimum 2-year follow-up and determine risk factors that were predictive of outcomes.

Forty consecutive patients (mean age 57.3 years, 87.5% male) who underwent SCR for massive irreparable rotator cuff tears (RCT) met the inclusion criteria. Minimum 2-year follow-up was obtained for 32 patients (80% follow-up). Patient demographics and preoperative clinical findings were collected. Postoperative data, including complications, patient satisfaction, strength and range-of-motion (ROM), and patient-reported outcomes were collected.

The Hamada score was ≤2 in 88% with average acromiohumeral interval distance of 6.8 mm. Preoperatively, 6 patients had external rotation lag (19%) and 6 had pseudoparalysis (19%). Intraoperative assessment of the subscapularis demonstrated true insufficiency in 38%. There was significant improvement in forward elevation (FE) (31° increase; P= .007) and strength in all planes (all P < .05). Patient-reported from SCR to reverse total shoulder arthroplasty (n= 3), there were no distinguishing characteristics present.

Superior capsular reconstruction is an effective salvage operation for massive irreparable RCT. Patients with pseudoparalysis or subscapularis insufficiency demonstrate significant postoperative improvement in FE and patient-reported outcomes.

We sought to evaluate the association between postoperative cam lesion measured by the femoroacetabular impingement resection (FAIR) arc and show 2-year patient outcomes following hip arthroscopy.

A retrospective review of prospectively gathered data from 2013-2017 was performed. All patients who underwent hip arthroscopy for femoroacetabular impingement resection (FAI) with ≥2-year follow-up were included. Cam FAIR arc measurements were made preoperatively and postoperatively on a 45° Dunn view radiograph. The clinical effect of postoperative cam maximal radial distance (MRD) was assessed using the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS). Patients were divided into subgroups based on relationship to the mean and standard deviations for cam MRD. One half standard deviation above the mean was found to be 3.15 mm.

Sixty-one hips in 59 consecutive patients (age 38.1 ± 13.1; body mass index [BMI] 25.5 ± 4.3; 36 females) were included. Mean preoperative and postoperative cam maximal radial distances (MRD) were 4.
