Legg Calve Perthes disease is a pediatric hip condition that leads to early hip degeneration. The efficacy of operative and nonoperative treatment is not well defined in the literature. Using the rate of total hip arthroplasty as a surrogate measure for symptomatic hip degeneration, the rate of total hip arthroplasty was compared in Legg Calve Perthes disease patients with and without previous surgical intervention in the province of Manitoba, Canada. A retrospective review was conducted using de-identified, individual-level administrative records of health services for the entire population of Manitoba. Codes for Legg Calve Perthes disease, femoral osteotomies, pelvic osteotomies, adductor tenotomies, and total hip arthroplasty were searched from 1984 to 2018. The rate of total hip arthroplasty in patients with Legg Calve Perthes disease was determined for two groups: (1) patients with earlier surgical intervention and (2) patients with no previous surgical intervention. Of the 202 patients included in the study, 180 had no prior surgery and 22 had prior surgery. The rate of total hip arthroplasty between the previous operative and nonoperative groups was found to be 32% and 40%, respectively (p = 0.458). There was no significant difference in rates of total hip arthroplasty in the operative and nonoperative groups. Further prospective studies are required to elucidate the differences in outcomes between operative and nonoperative treatment groups in patients with Legg Calve Perthes disease.

Background: There is a lack of prospective evidence to guide surgeons when making recommendations about the appropriate timing of surgical intervention for ruptured anterior cruciate ligament (ACL), activity modifications to reduce the risk of secondary injury before surgery, and the short- and long-term risks associated with delayed ACL reconstruction. This study aimed to determine whether longer wait times are associated with a prolonged decrease in quality of life and an increased incidence of secondary joint injury after ACL rupture. Methods: We recruited 53 patients who presented between 2013 and 2017 at a single sports medicine minor injury clinic with a suspected acute ACL rupture, based on clinical examination; ACL rupture was confirmed on magnetic resonance imaging. Patients were randomly allocated to undergo early reconstruction (< 12 wk after injury) or reconstruction after a regular wait time ([greater than or equal to] 12 wk). We compared scores on the ACL quality of life measure (ACL-QOL) and the incidence of secondary knee injury at baseline and at surgery between the 2 groups. Participants also completed the Tegner scale (level of activity) at the time of consent and within 7 days before surgery. Results: Twenty-eight patients were randomly assigned to the early surgery group and 25 patients to the regular wait time group. There was no difference in mean age between the 2 groups. There were no between-group differences in mean ACL-QOL score at the time of injury (28.5 [standard deviation (SD) 12.5] v. 28.5 [SD 12.6]) or at surgery (34.9 [SD 17.5] v. 38.0 [SD 17.5]). The mean wait time was significantly longer in the regular wait time group than in the early surgery group (29.6 wk [SD 13.2 wk] v. 10.6 wk [SD 5.1 wk], p = 0.001). In both groups, Tegner scale scores were significantly lower after than before ACL rupture (p < 0.001) and remained low while patients waited for surgery. There were no between-group differences in the incidence of chondral or meniscal injury at surgery, although the study was not adequately powered to draw any statistical conclusions. Conclusion: Wait time for ACL reconstruction may affect patients' quality of life, as it remained diminished for a longer period when surgery was delayed. A low activity level during the waiting period was observed in both groups; this low activity level may be one reason why no between-group differences in the incidence of secondary injury were observed. The findings suggest that patients with a limited activity level during the waiting period have a low risk of secondary injuries. Contexte : On manque de donnees prospectives pour guider les recommandations aux chirurgiens concernant le bon moment d'operer une rupture du ligament croise anterieur (LCA), les changements aux activites pour reduire le risque de blessure secondaire avant l'intervention, et les risques a court et a long terme d'une reconstruction tardive du LCA. Cette etude visait a determiner si les temps d'attente plus longs sont associes a une baisse prolongee de la qualite de vie et a une incidence accrue de blessure articulaire secondaire apres une rupture du LCA. Methodes : Nous avons recrute 53 patients d'une meme clinique de medecine du sport pour blessures mineures s'y etant presentes de 2013 a 2017 avec une rupture aigue du LCA soupconnee, selon devaluation clinique; la rupture a ete confirmee par imagerie par resonance magnetique. Les patients ont ete repartis au hasard entre 2 groupes : reconstruction rapide (< 12 sem. apres l'incident) ou dans les delais habituels ([greater than or equal to] 12 sem.). Nous avons ensuite compare les scores de qualite de vie lies au LCA (ACL-QOL) et l'incidence d'une blessure secondaire au genou au depart et au moment de l'operation. Les participants ont egalement rempli une echelle de Tegner (niveau d'activite) une premiere fois quand ils ont donne leur consentement, puis dans les 7 jours precedant l'intervention. Resultats : Vingt-huit patients ont ete places au hasard dans le groupe d'intervention rapide, et 25 patients, dans le groupe des delais habituels. Il n'y avait pas de difference entre les groupes quant a l'age moyen ni quant au score ACL-QOL moyen lors de l'incident (28,5 [ecart-type (E.-T.) 12,5] c. 28,5 [E.-T. 12,6]) ou de l'intervention (34,9 [E.-T. 17,5] c. 38,0 [E.-T. 17,5]). Le temps d'attente moyen etait significativement plus long chez le groupe des delais habituels que chez le groupe d'intervention rapide (29,6 sem. [E.-T. 13,2 sem.] c. 10,6 sem. [E.-T. 5,1 sem.]; p = 0,001). Dans les deux cas, les scores de l'echelle de Tegner etaient significativement inferieurs a ceux precedant la rupture (p < 0,001) et demeuraient faibles durant la periode precedant l'operation. Il n'y avait pas de difference entre les groupes quant a l'incidence de lesions chondrales ou meniscales au moment de l'intervention; l'etude n'avait toutefois pas la puissance necessaire pour tirer des conclusions statistiques. Conclusion : Le temps d'attente pour une reconstruction du LCA peut affecter la qualite de vie des patients, qui est demeuree reduite sur une periode prolongee dans le cas des interventions tardives. Le faible niveau d'activite durant l'attente, observe chez les 2 groupes, pourrait expliquer en partie l'absence de differences entre eux quant a l'incidence de blessures secondaires. Les resultats suggerent que les patients qui limitent leur niveau d'activite en attendant d'etre operes ont un faible risque de blessures secondaires., Anterior cruciate ligament (ACL) reconstruction is a common orthopedic operation, with more than 400 000 procedures completed each year in the United States (1) and close to 17 000 in [...]

Background While controversy remains as to the relative benefit of operative (OM) versus non-operative management (NOM) of Achilles tendon (AT) ruptures (ATR), few studies have examined the effect on high impact maneuvers such as jumping and hopping. Hypothesis/Purpose The purpose of this study was to determine if functional performance including strength, jumping, and hopping outcomes differed between OM and NOM of acute ATR. The secondary objective was to assess the degree of association between AT morphology and performance outcomes. Study Design Retrospective cohort with a single prospective evaluation. Methods All patients were treated at an institutional secondary care center. Eligible participants (n=12 OM; 12 NOM) who were treated with OM or NOM of ATR within three weeks of injury were evaluated a minimum 20 months following ATR. AT length, thickness and gastrocnemius muscle thickness were assessed with B-mode ultrasound. Isokinetic plantar flexor strength, hop tests and countermovement and drop jumps were completed. Two-way ANOVAS were completed on all tests with unilateral values, independent t-tests were used for bilateral outcomes, and linear regressions were completed to assess the relationship between normalized AT length and performance. Results Affected limb AT was elongated and thickened (p<0.01), gastrocnemius was atrophied (p< 0.01) and angle-specific plantar flexor torque was reduced at 120°/s when measured at 20° plantar flexion (p = 0.028). Single leg drop vertical jump was higher in OM (p = 0.015) with no difference for hop and jump tests. AT length was related to plantar flexor torque but had no relationship with hopping performance. Conclusions Hop test performance was maintained despite plantarflexion weakness, gastrocnemius atrophy, and AT elongation. This may be the result of compensatory movement patterns. AT length holds limited explanatory power in plantar flexor strength, although this relationship should be evaluated further. Level of Evidence Level III [ABSTRACT FROM AUTHOR]

Background: A multicenter, double-blinded randomized controlled trial comparing isolated Bankart repair (NO REMP) to Bankart repair with remplissage (REMP) reported benefits of remplissage in reducing recurrent instability at 2 years postoperative. The ongoing benefits beyond this time point are yet to be explored. Purpose: To (1) compare medium-term (3 to 9 years) outcomes of these previously randomized patients undergoing isolated Bankart repair (NO REMP) or Bankart repair with remplissage (REMP) to manage recurrent anterior glenohumeral instability; (2) examine the failure rate, overall recurrent instability, and reoperation rate. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Recruitment and randomization for the original randomized trial occurred between 2011 and 2017. Patients ≥14 years diagnosed with recurrent traumatic anterior shoulder instability with an engaging Hill-Sachs defect of any size were included. Those with a glenoid defect >15% were excluded. In 2020, participants were contacted by telephone and asked standardized questions regarding ensuing instances of subluxation, dislocation, or reoperation on their study shoulder. "Failure" was defined as a redislocation, and "overall recurrent instability" was described as a redislocation or ≥2 subluxations. Descriptive statistics, relative risk, and Kaplan-Meier survival curve analyses were performed. Results: A total of 108 participants were randomized, of whom 50 in the NO REMP group and 52 in the REMP group were included in the analyses in the original study. The mean number of months from surgery to the final follow-up was 49.3 and 53.8 months for the NO REMP and REMP groups, respectively. Failure rates were 22% (11/50) in the NO REMP group versus 8% (4/52) in the REMP group. Rates of overall recurrent instability were 30% (15/50) in the NO REMP group versus 10% (5/52) in the REMP group. Survival curves were significantly different, favoring REMP in both scenarios. Conclusion: For the treatment of traumatic recurrent anterior shoulder instability with a Hill-Sachs lesion and subcritical glenoid bone loss (<15%), a significantly lower rate of overall postoperative recurrent instability was observed with arthroscopic Bankart repair and remplissage than with isolated Bankart repair at a medium-term follow-up (mean of 4 years). Patients who did not receive a remplissage experienced a failure (redislocated) earlier and had a higher rate of revision/reoperation than those who received a concomitant remplissage.

Background: Despite recent advances in arthroscopic rotator cuff repair, the retear rate remains high. New methods to optimize healing rates must be sought. Bone channeling may create a quicker and more vigorous healing response by attracting autologous mesenchymal stem cells, cytokines, and growth factors to the repair site. Hypothesis: Arthroscopic rotator cuff repair with bone channeling would result in a higher healing rate compared with arthroscopic rotator cuff repair without adjuvant channeling. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Our primary objective was to compare healing rates in patients undergoing arthroscopic rotator cuff repair for degenerative tears, with and without bone channeling. Secondary objectives included comparisons of the Western Ontario Rotator Cuff Index (WORC) score, American Shoulder and Elbow Surgeons (ASES) score, Constant score, Constant strength subscore, and visual analog scale (VAS) for pain score between groups. Patients undergoing arthroscopic rotator cuff repair were recruited at 3 sites and were randomized to receive either bone channeling augmentation or standard repair. Healing was determined via ultrasound at 24 months postoperatively. WORC, ASES, and Constant scores were compared between groups at baseline and at 3, 6, 12, and 24 months postoperatively. Results: A total of 168 patients were enrolled between 2013 and 2018. Intention-to-treat analysis revealed no statistical differences in healing rates between the 2 interventions at 24 months postoperatively. Statistically significant improvements occurred in both groups from preoperatively to all time points for the WORC, the ASES score, the Constant score or Constant strength subscore, and the VAS for pain (P <.0001). No differences were observed between the bone channeling and control groups in WORC, ASES, Constant, and VAS pain scores at any time point. Conclusion: This trial did not demonstrate the superiority of intraoperative bone channeling in rotator cuff repair over standard rotator cuff repair at 24 months postoperatively. Healing rates, patient-reported function, and quality-of-life outcomes were similar between groups. Registration: NCT01877772 (ClinicalTrials.gov identifier). [ABSTRACT FROM AUTHOR]
