ABSTRACT
AIM OF THE STUDY: The purpose of the present study was to evaluate demographic characteristics of inmates in the Canton of Zurich (exposure), and investigate the changes in diseases and drug use between 2015 and 2020 (outcome). METHODS: The study prospectively evaluated 51,989 inmates admitted to the Police Prison Zurich in Switzerland between 1 April 2015 and 31 August 2020 and who were systematically medically assessed. A total of 19,027 (37%) inmates had one or more health conditions, which the authors recorded according to the International Classification of Diseases-10 (ICD-10), in addition to demographic data (country of origin, sex, age, year of imprisonment), as well as details of any drugs used (type and dosage). RESULTS: The 19,027 inmates with medical conditions had a mean age of 35.4±12.5 years (range 10-89) and comprised 16,489 males (87%). The inmates originated from 170 countries, including 4606 from Switzerland (24.2%), 4227 from Eastern Europe (22%) and 3432 from the Middle East & North Africa (18%). A total of 1631 inmates (9%) were enrolled in the medication-assisted treatment (MAT) programme, and 672 patients (4%) received a psychiatric evaluation. The proportions of foreign prisoners did not increase during the study period. There was a significant increase in the use of antipsychotics from year 1 to 5 (y = 0.866x; R2 = 0.902; p = 0.01) and anticonvulsants from year 1 to 4 (y = 1.27x; R2 = 0.823; p = 0.01), and a significant decrease in the use of analgesics from year 2 to 5 (y = -4.42x; R2 = 0.947; p = 0.03) and antianxiety drugs from year 1 to 4 (y = -3.31x; R2 = 0.989; p = 0.005). Inmates from Switzerland were most likely to use antianxiety drugs, while inmates from the Middle East & North Africa were most likely to use antipsychotics (OR 2.09; CI 1.88-2.34) and anticonvulsants (OR 3.52; CI 2.90-4.29), whereas inmates from Latin and North America were most likely to use herbal medicine (OR 1.50; CI 1.05-2.10). CONCLUSIONS: The findings of this study could help anticipate needs of prisons as well as improve treatment of disease and assist with substance use or abuse, particularly in the context of migration.

PURPOSE: The aim of this study was to report on the revision rates and clinical outcomes following dynamic intraligamentary stabilization (DIS) at a minimum follow-up of 5 years and to investigate which preoperative or intraoperative characteristics could influence revision rates or clinical scores. METHODS: The authors retrospectively assessed all 609 knees that underwent ACL repair using DIS at a single centre. At a minimum follow-up of 5 years, patients were assessed using the Lysholm, International Knee Documentation Committee (IKDC) and Tegner scores, as well as passive flexion and extension. RESULTS: At a follow-up of 5.1 ± 0.3 years (range, 5-10), of the 609 patients, 428 patients were available for clinical assessment. Anterior tibial translation decreased from 9.7 ± 2.1 to 7.8 ± 1.9 mm, and side-to-side difference decreased from 4.3 ± 2.3 to 1.5 ± 1.8 mm. The postoperative Lysholm score was 96.9 ± 5.6, subjective IKDC was 95.6 ± 6.1 and Tegner scores ranged from 4 to 11, of which 51% of patients had a score of 7 or more. The estimated survival rate was 86% for the first half of the cohort and increased to 91% for the second half of the cohort. CONCLUSION: At a minimum follow-up of 5 years following ACL repair using DIS, it was found that it grants satisfactory clinical outcomes and that surgeons should inform patients who have predispositions about the higher risk of revision. LEVEL OF EVIDENCE: Level IV retrospective study.
ABSTRACT
BACKGROUND: Recent systematic reviews on the outcomes of sulcus-deepening trochleoplasty with adjuvant medial patellofemoral ligament (MPFL) reconstruction at a follow-up of 2 to 6 years have found that the procedure grants good clinical outcomes with low redislocation rates. However, there is a lack of evidence in the literature regarding mid- and long-term follow-ups. PURPOSE: To evaluate the radiographic and clinical outcomes of thick-flap sulcus-deepening trochleoplasty with MPFL reconstruction at a minimum follow-up of 10 years to assess the signs of patellofemoral arthritis, incidence of recurrent dislocation, and grade of patient satisfaction. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The authors evaluated a retrospective series of 43 patients (48 knees) who underwent sulcus-deepening trochleoplasty between 2003 and 2013. All patients underwent thick-flap sulcus-deepening trochleoplasty with additional MPFL reconstruction. All patients were assessed at a minimum follow-up of 10 years by an independent clinician who noted any patellar redislocation or reoperations in the operated knee and collected the International Knee Documentation Committee (IKDC), Kujala, and satisfaction scores. Furthermore, a radiographic examination was performed to assess patellar height using the Caton-Deschamps index and patellofemoral arthritis using the Iwano classification. RESULTS: At a mean follow-up of 14.8 ± 2.1 years (range, 10-20 years), 4 patients (4 knees) were lost to follow-up (8.3%). The satisfaction, Kujala, and IKDC scores were 8.2 ± 1.6, 77.5 ± 14.4, and 65.7 ± 13.5, respectively. Only 1 patient reported a traumatic patellar dislocation (2%). Radiographs at the final follow-up were available for 34 knees, which revealed Iwano grade 1 in 14 knees (41%), Iwano grade 2 in 7 knees (21%), and no patellofemoral arthritis in 13 knees (38%). CONCLUSION: Sulcus-deepening trochleoplasty with MPFL reconstruction provides satisfactory results and prevents patellar redislocations with no or minimal patellofemoral arthritis.

Purpose: To investigate the healing of the quadriceps tendon donor site after partial thickness graft harvesting through ultrasound imaging at a short-term follow-up of 6-month following anterior cruciate ligament reconstruction (ACLR) and to investigate the clinical outcomes. Methods: Between March 2019 and August 2020, 61 knees were retrospectively included in this study. Intraoperatively, the length, width and thickness of the harvested QT graft were measured. At a 6-month follow-up, patients were assessed by one of five radiologists, following the same protocol to calculate the defect volume, and patients performed a self-evaluation of pain on the Visual Analogue Scale, International Knee Documentation Committee (IKDC) and the Knee injury and Osteoarthritis Outcome Scores (KOOS). Results: Intraoperatively, the QT grafts had a volume of 4635.4 ± 912.5 mm3. Postoperatively, ultrasound was performed at 6.5 ± 0.7 months, and the defect volume was 323.3 ± 389.2 mm3, representing a healing rate of 93% ± 9% of the donor site. At a minimum 6-month follow-up, IKDC was 61.6 ± 16 and KOOS was 70.2 ± 16.6. Age was significantly associated with the healing rate (ß: -0.005; p = 0.032). Conclusion: At 6 months follow-up, the defect size of the QT donor site had healed by 93 ± 9% leaving a mean defect volume of 323.3 mm3 according to ultrasound measurements. This suggests that the QT has a high capacity for healing after graft harvesting, with 10 patients reaching full defect closure 6 months after surgery. The clinical relevance of these findings is that the quadriceps tendon donor site has high rates of healing, but surgeons should be aware of lower healing rates in older patients. Level of Evidence: Level IV, retrospective case series.
ABSTRACT
Background: The epidemiology of musculoskeletal injuries at the Australian Open, Wimbledon, and US Open tennis tournaments has been investigated in recent studies; however, there is no published literature on the incidence of musculoskeletal injuries at the French Open. Purpose: To describe the incidence, location, and type of musculoskeletal injuries in tennis players during the French Open tournament from 2011 to 2022. Study Design: Descriptive epidemiology study. Methods: A review was performed of all injuries documented by a multidisciplinary medical team during the French Open from 2011 to 2022. All musculoskeletal injuries that occurred during the main draw of the female and male singles or doubles matches were included. Descriptive statistics were used to summarize the data. Injury locations were grouped into regions as well as into upper limb, trunk, and lower limb. Results: In total, there were 750 injuries in 687 tennis players, resulting in a mean of 62.5 injuries per tournament; however, there were no obvious trends in injury incidence over the time frame evaluated. The number of injuries in female and male players was similar (392 vs 358, respectively). The most common injury regions were the thigh/hip/pelvis (n = 156), ankle/foot (n = 114), and spine (n = 103). The most common injury types were muscle-related (n = 244), tendon-related (n = 207), and joint-related (n = 163), and the most affected muscles were the adductors (n = 45), rectus abdominis (n = 38), and lumbar muscles (n = 25). Conclusion: Over the 12-year period from 2011 to 2022 female and male players experienced similar numbers of musculoskeletal injuries, with most injuries occurring in the lower limbs compared with the upper limbs and trunk.
ABSTRACT
Purpose: To determine, from a sizable cohort of reverse shoulder arthroplasty (RSA), whether the deltopectoral (DP) or anterosuperior (AS) approach grant better outcomes at a minimum follow-up of 24 months. Methods: The authors reviewed 743 RSAs in patients with primary osteoarthritis (OA) with or without rotator cuff lesions and secondary OA due to rotator cuff tears. The DP approach was used in 540 and the AS approach in 203. Pre- and post-operative constant scores (CSs) and shoulder range of motion were recorded. Results: Of the initial cohort of 743 shoulders, 193 (25.7%) were lost to follow-up, 16 (2.1%) died, and 33 (4.4%) were revised; 540 shoulders were operated using DP approach (73%), of which 22 were revised (4.1%), while 203 were operated using the AS approach (27%), of which 11 were revised (5.4%). Propensity score matching resulted in two groups: 172 shoulders operated by DP approach, and 88 shoulders operated by AS approach. Comparing outcomes of the matched groups at 2 or more years also revealed that, compared to the AS approach, the DP approach resulted in significantly better post-operative CSs (67.3 ± 14.0° vs 60.8 ± 18.3, P = 0.017), active forward elevation (137° ± 27.4° vs 129° ± 29.8; P = 0.031). Conclusion: At 2 or more years following RSA, the DP approach granted significantly better CS (by 6.5 points) and active forward elevation (by 8°) compared to the AS approach. The differences observed are clinically relevant and must be considered to manage patient expectations following RSA and for selecting surgical approach depending on their functional needs. Level of evidence: III, comparative study.
ABSTRACT
The original technique for tibial deflexion osteotomy (TDO) was first described by Henri Dejour during the Lyon knee meeting in 1991 to reduce excessive posterior tibial slope during second revision anterior cruciate ligament reconstruction (ACLR). The technique is nowadays increasingly performed during first-revision ACLR in patients at risk for graft retear. This Technical Note describes and updates the original TDO technique.
ABSTRACT
The purpose was to determine the accuracy of the techniques of Lopes et al. and Michels et al., compared to ultrasound, to locate the center of the calcaneal footprint of the CFL in healthy volunteers. The authors recruited 17 healthy adult volunteers at 1 center with no current ankle pathologies and no previous surgical antecedents on either ankle. The authors recorded the age, sex, height, BMI, and ankle side for each volunteer. Measurements were made on both ankles of the 17 volunteers to increase the sample size and ensure less dispersion of data, independently by 2 surgeons: 1 senior surgeon with 15 years' experience and 1 junior with 3 years' experience. The location of the center of the calcaneal footprint of the CFL was determined by each surgeon using 3 methods: (1) the cutaneous technique of Lopes et al., (2) the cutaneous technique of Michels et al., and (3) ultrasound imaging. The 17 volunteers (34 feet) had a mean age of 26.3 ± 8.7 and a BMI of 21.7 ± 2.9. The Michels point was significantly closer (4.6 ± 3.7 mm) than the Lopes point (11.1 ± 5.4 mm) to the true center of the calcaneal footprint of the CFL determined by ultrasound, notably in the vertical direction. The Michels point was located significantly closer to the true center of the calcaneal footprint of the CFL and demonstrated less dispersion than the Lopes point, indicated by significantly lower absolute mean deviation from the true center of the calcaneal footprint of the CFL, and that ultrasound is therefore preferred to locate the footprint the CFL.

PURPOSE: To determine the rate and time of return to duty following anterior cruciate ligament reconstruction (ACLR) in military members, and to determine whether their outcomes are influenced by patient characteristics or surgical parameters. METHODS: We prospectively assessed 280 military members that underwent ACLR. 27 were excluded due to multi-ligamentous injuries or revision surgery, two did not provide informed consent and 62 were lost to follow-up. Patient demographics, pre-injury physical workload, complications and whether/when patients resumed duty and sports were noted, as well as clinical outcomes at a minimum follow-up of one year, including Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee score (IKDC), Lysholm, and Tegner scale. RESULTS: The final cohort of 189 military members (82% men) had mean age of 25.5 ± 3.4 (range,19-38) at ACLR. At 3.3 ± 1.6 years (range, 1.0-6.3), the Tegner score was 6.1 ± 2.0, Lysholm was 87.0 ± 13.7, IKDC was 80.1 ± 15.7, and KOOS was 81.1 ± 14.8. Only 144 patients (76%) resumed duty, at 9.5 ± 5.3 months (range,1-28), and 141 patients (75%) resumed sport, at 10.2 ± 6.2 months (range,1-35). Multivariable analysis revealed that return to duty was less likely in patients with higher BMI (OR,0.89;p = 0.025), but more likely in patients that followed military physiotherapy (OR,2.76;p = 0.017) and with higher pre-injury physical workload (OR,3.93;p = 0.010). CONCLUSION: At a follow-up of 3.3 ± 1.6 years, 76% returned to duty at 9.5 ± 5.3 months, and 75% returned to their main sport at 10.2 ± 6.2 months. Patients with higher BMI are significantly less likely to resume military duty and sports; those that followed military physiotherapy were most likely to resume duty, while those that had greater pre-injury physical workload were more likely to both resume duty and sport.

The purpose was to systematically review and synthesize the literature on treatment modalities for shoulder stiffness following rotator cuff repair (RCR) and investigate which modality provides the greatest postoperative range of motion (ROM). A search was performed on PubMed, Embase, and Cochrane. Clinical case series and comparative studies that report pre- and posttreatment ROM of shoulder stiffness following RCR were included. Studies that exclusively assess idiopathic frozen shoulder or primary shoulder stiffness were excluded. Five eligible studies that reported on a total of 177 patients who underwent treatment for shoulder stiffness following RCR were included. The ranges of postoperative ROM following arthroscopic capsular release were 158°-166° for active forward elevation (AFE) and 53°-59° for external rotation (ER). The ranges of postoperative ROM following infiltration were 146°-163° for AFE and 34°-35° for ER. The ranges of postoperative ROM following rehabilitation were 166° for AFE and 62° for ER. For AFE, 4 studies (5 data sets) were eligible for meta-analysis, which indicated better AFE when treated with a mean difference (MD) of 5.10° with no heterogeneity (I2 = 0%, CI, 0.83-9.38). For ER, 3 studies (4 data sets) were eligible for meta-analysis, which indicated better ER without treatment with an MD of 4.59° with no heterogeneity (I2 = 0%, CI, -7.04 to -2.13). For the treatment of shoulder stiffness following RCR, all included treatments improved the ROM, resulting in comparable AFE and ER compared to the comparative group. Among the treatment modalities, arthroscopic capsular release granted the greatest posttreatment AFE, while rehabilitation granted the greatest posttreatment ER.
ABSTRACT
The aim of this study is to determine whether adjuvant Distal Clavicle Resection (DCR) improves outcomes of Rotator Cuff Repair (RCR) in terms of ROM, clinical scores as well as reducing complications and/or reoperations. This systematic review conforms to the PRISMA guidelines. Studies were included if they compared outcomes of RCR with and without adjuvant DCR and reported on postoperative ROM, clinical scores, complications, and/or reoperations. Seven studies that comprised 1572 shoulders which underwent RCR at a follow-up ranged 8-54 months: 398 with adjuvant DCR and 1174 without DCR. No significant differences were found between patients that had DCR versus those that did not have DCR, in terms of postoperative clinical scores (ASES, Constant, pVAS), postoperative ROM (AFE, external and internal rotation), retear rate and reoperation rate. There were no significant differences in ROM, clinical scores, or rates of retears and reoperations between patients that underwent RCR with or without adjuvant DCR. There is insufficient evidence to support routine DCR during RCR; the incidence of new or residual acromioclavicular joint (ACJ) pain after RCR with adjuvant DCR is higher than following isolated RCR, which could in fact induce iatrogenic morbidity and therefore does not justify the additional surgery time and costs of routine adjuvant DCR.
ABSTRACT
OBJECTIVES: The purpose of the present study was to investigate associations between revision-free survival and functional scores of total knee arthroplasty (TKA) and moon phase on the day of surgery, as well as operations performed on a Friday 13th. PARTICIPANTS: The data of all patients that received TKA between 2003 and 2019 were extracted from the Tyrol arthroplasty registry. Patients that had undergone previous total or partial knee arthroplasty as well as patients that had missing pre- or post-operative WOMAC were excluded. Patients were allocated to one of the following four groups according to moon phase on the day of surgery: new, waxing, full and waning. Patients operated on a Friday 13th were also identified and compared to patients operated on any other days/dates. A total of 5923 patients met the inclusion criteria, with mean age of 69 ± 9 years, and comprising 62% women. RESULTS: There were no significant differences in revision-free survival among the four moon phase groups (p = 0.479), and no significant differences in preoperative and postoperative total WOMAC (p = 0.260, p = 0.122), There were no significant differences in revision-free survival patients operated on Friday 13th vs. other days/dates (p = 0.440). The preoperative total WOMAC was significantly worse for patients operated on a Friday 13th (p = 0.013), which was observed in the pain (p = 0.032) and function (p = 0.010) subscales. There were no significant differences in postoperative total WOMAC at 1 year follow-up (p = 0.122). CONCLUSIONS: Neither moon phase on the day of surgery nor Friday 13th were associated with revision-free survival or clinical scores of TKA. Patients operated on a Friday 13th had significantly worse preoperative total WOMAC but similar postoperative total WOMAC at 1-year follow-up. These findings could help reassure patients that TKA renders consistent outcomes regardless of the preoperative pain or function, and in spite of bad omens or moon phases.

Background: Latissimus dorsi tendon transfer (LDTT) is increasingly performed with arthroscopic assistance, requiring an open axillary incision, which could increase risks of infection, hematoma, and lymphoedema. Technological advancements now enable LDTT to be fully arthroscopic, but its benefits and safety have not yet been confirmed. Purpose: To compare the clinical outcomes and complication rates of arthroscopic-assisted versus full-arthroscopic LDTT for irreparable posterosuperior massive rotator cuff tears in shoulders with no surgical antecedents. Study Design: Cohort study; Level of evidence, 3. Methods: The study included 90 patients who had undergone LDTT over 4 consecutive years by the same surgeon and did not have prior surgery. During the first 2 study years, all procedures were arthroscopically assisted (n = 52), while during the last 2 years, all procedures were fully arthroscopic (n = 38). Procedure duration and all complications were recorded, as well as clinical scores and range of motion at minimum 24-month follow-up. To enable direct comparison between the techniques, propensity score matching was used to obtain 2 groups with equivalent age, sex, and follow-up. Results: From the initial cohort of 52 patients who underwent arthroscopic-assisted LDTT, 8 had complications (15.4%), of which 3 (5.7%) required conversion to reverse shoulder arthroplasty and 2 (3.8%) required drainage or lavage. From the initial cohort of 38 patients who had full-arthroscopic LDTT, 5 had complications (13.2%), of which 2 (5.2%) required conversion to reverse shoulder arthroplasty but no patients (0%) required other procedures. Propensity score matching resulted in 2 groups, each comprising 31 patients, with similar outcomes in terms of clinical scores and range of motion. The procedure time was about 18 minutes shorter for full-arthroscopic LDTT, which had different complications (2 axillary nerve pareses) as compared with arthroscopic-assisted LDTT (1 hematoma and 2 infections). Conclusion: Equivalent outcomes at minimum 24-month follow-up were found for arthroscopic-assisted and full-arthroscopic LDTT in terms of complications rates (15.4% and 13.2%, respectively), conversion to reverse shoulder arthroplasty (5.7% and 5.2%), clinical scores, and range of motion.
ABSTRACT
Background: Recent meta-analyses have advised against distal clavicle resection (DCR) as an adjuvant procedure during rotator cuff repair (RCR), whether performed routinely or in shoulders diagnosed with symptomatic acromioclavicular joint (ACJ) arthropathy. However, the efficacy of DCR as a secondary procedure in patients with persistent pain attributed to symptomatic ACJ arthropathy remains unknown. Purpose: To evaluate outcomes of secondary DCR in patients with failed nonoperative treatment of symptomatic ACJ arthropathy after isolated RCR with complete tendon healing. Study Design: Case series; Level of evidence, 4. Methods: Between 2008 and 2018, the senior surgeon performed isolated RCR in 1935 patients, of which 23 (1.2%) presented with ACJ pain and discomfort at ≥12 months after the index RCR, despite complete healing of repaired tendons. Those 23 patients underwent secondary DCR, as ACJ arthropathy was confirmed clinically and radiographically. Clinical assessment before DCR included the Subjective Shoulder Value (SSV) and pain at rest. Clinical assessment at >12 months after DCR included the SSV, pain at rest, Constant-Murley score, range of motion, and satisfaction. Pre- and post-DCR SSV and pain scores were compared. Results: Of the initial cohort, 5 patients did not consent to the use of their data, leaving 18 patients aged 53.3 ± 7.6 years (mean ± SD; range, 39-68 years) for outcome assessment. At a mean follow-up of 7.0 ± 3.1 years after DCR, the SSV significantly improved from 58.7 ± 17.2 to 76.1 ± 20.2 (P < .001), and the pain at rest significantly decreased from 4.7 ± 1.5 to 2.8 ± 1.9 (P < .001). At final follow-up, the Constant-Murley score was 70.2 ± 21.0. Of 18 patients, 15 had none or mild residual pain (0-2; 83%), while 3 had substantial residual pain (5 or 6; 17%). Only 1 of the 3 patients with substantial residual pain had a poor SSV score (20 points) and was against opting for DCR in retrospect. No patient had infections or gross ACJ instability after DCR. Conclusion: Secondary DCR for cases of symptomatic ACJ arthropathy after isolated RCR with complete tendon healing reduced pain in 83% of patients, and 94% were satisfied and would undergo secondary DCR again.
ABSTRACT
Purpose: To evaluate indications and factors that influence long-term clinical outcomes and revision rates for reverse shoulder arthroplasty (RSA) in shoulders with irreparable massive rotator cuff tears (mRCTs) or cuff tear arthropathies (CTAs). Methods: The authors retrospectively evaluated a consecutive series of shoulders with no fracture sequelae that underwent primary RSA between 2011 and 2013. Independent observers collected demographic data, surgical techniques, and implant types, as well as primary outcome measures such as American Shoulder and Elbow Society (ASES) score and Constant score (CS). Study design: Case series, level IV. Results: From the initial series of 123 patients that underwent RSA, 29 patients died (24%) for reasons unrelated to the shoulder arthroplasty, 11 were lost to follow-up (9%), and 4 required revision surgery (3%). The final cohort of 79 patients comprised 55 women (70%), and 24 men (30%), aged 72.7 ± 7.0. At a final follow-up of 8.9 ± 0.6 years (range: 7.4-10.3) the absolute CS was 59.0 ± 16.2, the age-/sex-adjusted CS was 76.6 ± 41.2, and ASES was 77.1 ± 20.3. Univariable analysis revealed no associations for absolute CS, but revealed that age-/sex-adjusted CS was significantly lower for patients with high blood pressure (ß = -15.8, p = .025). Conclusions: At a minimum follow-up of 7.4 years, the absolute CS was 59.0 ± 16.2, the age-/sex-adjusted CS was 87.4 ± 24.1 and ASES was 77.1 ± 20.3. When stratifying the outcomes of RSA by indication, there were no significant differences in patients with mRCTs versus CTA in terms of absolute CS, age-/sex-adjusted CS, and ASES. Univariable analysis revealed no association with absolute and age-/sex-adjusted CS for type of indication or surgical approach.
ABSTRACT
PURPOSE: To compare the clinical and functional outcomes of arthroscopic rotator cuff repair over a period of 2 years using three postoperative rehabilitation modalities: aquatic therapy, land-based therapy, and self-rehabilitation therapy. The null hypothesis was that aquatic therapy would provide no difference in Constant score compared to land-based therapy and self-rehabilitation therapy. METHODS: A prospective study was performed on subjects scheduled for arthroscopic rotator cuff repair between 2012 and 2017 that complied with the following criteria: (i) small to medium sized symptomatic supraspinatus and/or infraspinatus tendon tears, (ii) low to moderate tendon retraction according to Patte, and (iii) fatty infiltration stage ≤2. Patients were allocated to perform either aquatic therapy, land-based therapy, or self-rehabilitation therapy for 2-4 months. Independent observers blinded to the study design collected Constant score, SSV, and patient satisfaction at 2 months, 3 months, 6 months, 1 year and 2 years. STUDY DESIGN: Level III, cohort study RESULTS: At 2 months follow-up, patients performing aquatic therapy had significantly higher Constant scores (p < 0.001) and SSV (p < 0.001) compared to those performing land-based therapy or self-rehabilitation therapy. At 3 months follow-up, patients performing aquatic therapy had significantly higher Constant scores (p < 0.001), and SSV (p < 0.001), both of which exceeded the respective minimal clinically important differences (MCIDs) of 10.4 and 12. Patients performing aquatic therapy continued to have significantly higher Constant scores and SSV at 6 months, 1 year, and 2 years. CONCLUSION: Aquatic therapy has a very limited positive effect on clinical outcomes at 3 months after surgery, but yields no relevant improvements on function or satisfaction at 1 to 2 years follow-up.
ABSTRACT
PURPOSE: To synthesize the literature and critically appraise current evidence to determine the most accurate physical examination (clinical test or ultrasound) to detect pathologies of the long head of the biceps tendon (LHBT). METHODS: A search was performed on PubMed, Embase®, and Cochrane. Studies that compared the diagnostic accuracy of clinical tests or ultrasound versus arthroscopy for the assessment of LHBT pathologies were included. RESULTS: Seven studies were included reporting on a total of 448 patients. One study on instability using ultrasound reported sensitivity and specificity of 1.00 and 0.96, respectively. Two studies on full-thickness tears using ultrasound reported sensitivity and specificity of 0.88-0.95 and 0.71-0.98, respectively. Four studies on partial-thickness LHBT tears reported sensitivity and specificity of 0.17-0.68 and 0.38-0.92, respectively, for clinical tests, versus 0.27-0.71 and 0.71-1.00, respectively, for ultrasound. Three studies on other LHBT pathologies reported sensitivity and specificity of 0.18-0.79 and 0.53-0.85, respectively, for clinical tests, versus 0.50 and 1.00, respectively, for ultrasound. CONCLUSION: To detect LHBT pathologies, sensitivity is high-to-excellent using ultrasound, and moderate using Neer's sign and Speed's test, while specificity is high-to-excellent also using ultrasound, as well as the belly press, lift-off and Kibler's tests. The clinical relevance of these findings is that clinical tests are only reliable either to confirm or rule out LHBT pathologies, whereas ultrasound is reliable both to confirm and rule out LHBT pathologies. While diagnostic imaging cannot substitute for patient history and physical examination, the reliability and accessibility of ultrasound render it practical for routine use, particularly if clinical tests render unclear or contradictory findings. LEVEL OF EVIDENCE: Level III.

Background: Rapid consolidation of the bone block is paramount for the success of the Latarjet procedure. Noncannulated screws have shown satisfactory long-term bone block fusion, while cannulated screws are challenged with inferior mechanical properties and fusion rates. Purpose: To report outcomes of the Latarjet procedure using cannulated screws, notably bone block fusion and complication rates at 3 months, as well as clinical scores and return to sports at minimum 2 years postoperatively. Study Design: Case series; Level of evidence, 4. Methods: We reviewed the records of 124 consecutive patients (124 shoulders) who underwent primary Latarjet procedures using cannulated screws between 2015 and 2018. All patients underwent clinical examination at 3 months postoperatively, including range of motion and radiographs to assess graft fusion. The Walch-Duplay score, Rowe score, Subjective Shoulder Value, and visual analog scale for pain were collected at a minimum follow-up of 2 years. Results: Overall, 9 patients (7%) required reoperation: 7 (6%) had screw removal for unexplained residual pain, 1 (0.8%) had lavage for deep infection, and 1 (0.8%) had evacuation to treat a hematoma. Furthermore, 3 patients (2.4%) had recurrent instability, none of whom underwent reoperation. At 3-month follow-up, all 124 shoulders showed complete radiographic graft fusion, and at 40 ± 11 months (mean ± SD; range, 24-64 months), 88% of patients had returned to sport (109/124), the Walch-Duplay score was 86 ± 14, Rowe was 84 ± 15, Subjective Shoulder Value was 88 ± 11, and visual analog scale for pain was 1 ± 1. Conclusion: The clinical relevance of these findings is that 4.5-mm cannulated screws are safe and effective for primary Latarjet procedures and grant adequate graft healing, with low recurrence of instability and a high rate of return to sports.
ABSTRACT
PURPOSE: To determine the reliability of anatomic references for mediolateral component positioning in shoulder arthroplasty. MATERIALS AND METHODS: The computed tomography scans of 86 shoulders free of arthritic or anatomic deformities were studied. Two surgeons independently digitized a series of points, including the intersection of the 3 bone branches of the scapular spine (Y), the center of the glenoid surface (G), the most medial point of the scapula (MS), the cortical convergence (CC) of the anterior and posterior margins of the glenoid, the base of the coracoid (BC), the anterior (HA) and posterior (HP) margins of the subchondral bone. RESULTS: The mean mediolateral distances between G and Y, BC, CC were respectively - 19.6 mm, - 1.5 mm, and - 36.8 mm. The consistency of anatomic landmarks was greatest for Y (standard deviation (SD) =2.3 mm; interquartile range (IQR) =3 mm), compared to BC (SD = 4.6 mm; IQR = 7 mm), and CC (SD = 6.6 mm; IQR = 8 mm). The repeatability of anatomic landmarks was excellent for all measurements. The mean ratios (relative to humeral head size) of distances between G and Y, BC, CC were respectively - 0.45, - 0.04, and - 0.85. The consistency of ratios was greatest for Y (SD = 0.05; IQR = 0.06), compared to BC (SD = 0.11; IQR = 0.14), and CC (SD = 0.13; IQR = 0.17). The repeatability of ratios was excellent for Y and BC, while it was good for CC. CONCLUSIONS: The Y-plane is a reliable reference for glenoid component positioning in shoulder arthroplasty, with a consistent distance from the center of the glenoid surface, and could therefore be suitable for preoperative planning. STUDY DESIGN: Level III, comparative anatomic study.
