Impaired Symmetry in Single-Leg Vertical Jump and Drop Jump Performance 7 Months After ACL Reconstruction.

Background: Anterior cruciate ligament reconstruction (ACLR) continues to be associated with a variable rate of return to sports and a concerning rate of further anterior cruciate ligament injury. Persistent functional deficits may explain these results and support the need to keep exploring lower limb functional indexes, especially during vertical jumping. This would help improve rehabilitation through the return-to-sports continuum and improve postoperative outcomes. Hypothesis: Vertical jumping performance indexes are impaired among patients 7 months after ACLR. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 202 patients who underwent ACLR and 50 healthy participants performed single-leg vertical jump (SLVJ) and single-leg drop jump (SLDJ) testing. Jump height (H) as well as reactive strength index (RSI) were assessed and the limb symmetry index (LSI) of each parameter was compared between both groups. Vertical jumping indexes were also compared between healthy participants and the injured and contralateral legs of ACLR patients. Frequency analysis (chi-square test) of participants exhibiting an LSI >90% for each parameter was calculated in both groups. The level of association between SLVJ-H, SLDJ-H, and SLDJ-RSI was evaluated using the Pearson coefficient (r). Results: At 6.6 ± 0.7 months (mean ± SD) postoperatively, participants after ACLR exhibited poorer LSI than the control group for all parameters (79.1 ± 14.8 vs 93.9 ± 4.5, 77.3 ± 14.6 vs 93.4 ± 5.2, and 71.9 ± 17.4 vs 93.4 ± 3.8; all P < .001; for the SLVJ-H, SLDJ-H, and SLDJ-RSI, respectively). Vertical jumping performance was lower on both injured and contralateral legs compared with healthy participants (all P < .001). Only 27%, 25%, and 16% of the ACLR patients exhibited an LSI >90% for the SLVJ-H, SLDJ-H, and SLDJ-RSI, respectively, in comparison with 80%, 72%, and 86% in the control group. Moderate correlations were observed between SLDJ-H and SLVJ-H (r = 0.494; P < .001) as well as between SLDJ-RSI and SLVJ-H (r = 0.488; P < .001) in the ACLR group. Conclusion: Vertical jumping indexes (both symmetry and absolute values) were highly impaired 7 months after ACLR. Deficits were more marked for reactive strength ability. Clinicians should focus on restoring vertical jumping abilities to improve functional performance after ACLR.

Returning to pre-injury level of sports before 9 months after medial patellofemoral ligament reconstruction increases the incidence of anterior knee pain in young patients.

PURPOSE: This study aimed to identify the risk factors for anterior knee pain (AKP) after medial patellofemoral ligament reconstruction (MPFLR). METHODS: Patients aged 15-35 years who underwent isolated MPFLR between 2012 and 2022 were included in the study. These patients were divided into two groups (AKP and control group). Patient demographics and preoperative and postoperative clinical outcomes between the two groups were assessed and compared. Univariate logistic regression analysis was performed to explore the potential risk factors associated with postoperative AKP. Subgroup analysis stratified the results based on the time to return to sports (RTS) (>9 and ≤9 months). Furthermore, Spearman correlation analysis was performed to investigate the association between Kujala score and time to RTS. RESULTS: A total of 206 patients were included (AKP, n = 59; control, n = 147). At the 2-year follow-up, patients with AKP demonstrated a shorter duration in returning to their pre-injury activity level compared to those without AKP (9.0 ± 3.6 vs. 10.3 ± 2.7 months, p < 0.05). RTS earlier than 9 months after MPFLR was the only significant risk factor associated with postoperative AKP (odds ratio, 2.13, 95% confidence interval, 1.03-4.39; p < 0.05). Further subgroup analysis revealed that patient RTS earlier than 9 months exhibited worse patient-reported outcomes in both the total cohort and control group (p < 0.05). Furthermore, among patient RTS within 9 months, a longer recovery duration before RTS strongly correlated with a higher Kujala score (R = 0.670, p < 0.001). CONCLUSIONS: Young patients who RTS at their pre-injury levels before 9 months after MPFLR have a higher incidence of postoperative AKP and poorer functional outcomes compared to those who delay their return. Specifically, within the first 9 months after MPFLR, the earlier the RTS, the more severe the AKP symptoms. Careful consideration of the timing for RTS may help reduce the incidence of postoperative AKP. LEVEL OF EVIDENCE: Level III.

Return to Sports Following Spondylolysis Surgery in Children and Adolescents: A Systematic Review.

Background: Spondylolysis is common in athletes participating in gymnastics, football, dance, and weightlifting. Few studies have reviewed return to sports (RTS) rates in young athletes after surgical intervention for spondylolysis. Purposes: We sought to review the literature on RTS frequencies and timing, as well as postoperative treatment, in children and adolescents who underwent spondylolysis surgery. Methods: This was a systematic review, using the PubMed, Embase, and Cochrane databases, of primary, peer-reviewed studies published from 2014 to 2022 that investigated child and adolescent RTS after spondylolysis surgery. Each author independently reviewed each study's design, number of participants, age range, fixation, postoperative course of treatment, frequency of RTS, and reasons for failure of RTS. Results: The initial search produced 106 articles; 25 were reviewed in full and 9 were included in the final analysis, with a combined total of 177 patients. Sample sizes ranged from 5 to 52 participants. The most common fixations were direct repair (6 studies, n = 120), indirect repair (3 studies, n = 22), and fusion (2 studies, n = 35). Five studies mentioned the use of immediate postoperative immobilization. Physical therapy programs were initiated most often at 6 weeks postoperatively. The RTS rate of the 177 athletes (median age younger than 23 years) was 76% to 100%. The most common reason for failure to RTS was lower back pain. Conclusions: This systematic review suggests that young athletes RTS at a high rate following spondylolysis surgery, but more rigorous study is warranted. The review also found varied preferred fixation methodologies and postoperative treatment regimens across the available studies.

Comparative study of two different horizontal stabilisation methods in arthroscopically assisted coracoclavicular stabilisation for acute acromioclavicular joint dislocations-Good clinical outcome and no correlation to recurrent anteroposterior instability.

PURPOSE: The hypothesis of this study was that acromioclavicular K-wire transfixation is noninferior to horizontal FiberTape cerclage in terms of vertical and horizontal stability in the short follow-up period of acute acromioclavicular joint (ACJ) dislocations fixed with an arthroscopically assisted coracoclavicular single bundle endobutton cerclage system. The secondary aim was to investigate the impact of postoperative recurrent instability on clinical outcomes in these populations. METHODS: In this consecutive clinical trial, all patients who underwent surgery for acute AC joint dislocation between January 2017 and December 2021 were included. Two groups were formed according to the additional AC stabilisation technique (K-wire group, cerclage group). Clinical examination and bilateral radiologic analysis (Zanca stress view, Alexander view) were performed with a follow-up period of at least 12 months. Satisfaction, return to sports, active range of motion, global shoulder scores and specific shoulder scores including constant score, disabilities of the arm, shoulder and hand (DASH) score and ACJ instability score (ACJI) were evaluated. Complications, including recurrent instability, and revision rate were assessed. RESULTS: Included were 59 patients (32 K-wire group, 27 cerclage group, 92% male, median follow-up 33 months). No significant differences were found in the clinical outcome parameters between the different techniques, except for the DASH value (superior in the K-wire group). Recurrent anteroposterior instability was radiographically detected in 27% of patients. No correlation was found between anteroposterior instability and clinical outcome parameters. There was no revision surgery due to chronic ACJ instability. CONCLUSION: Horizontal ACJ stabilisation with temporary K-wire transfixation does not appear to be inferior to a FiberTape cerclage technique in acute ACJ dislocations stabilised in an arthroscopically assisted single bundle DogBone technique. Recurrent ACJ instability detected radiographically does not necessarily correlate with the functional outcome and can be well compensated. LEVEL OF EVIDENCE: Level III.

Return to Sports in Stress Reaction and Stress Fractures in Indian Athletes: A Case Series.

Introduction: A stress fracture is a painful condition which occurs when the adaptive ability of the bone is unbalanced. This imbalance predominantly occurs due to increased intensity, frequency, or duration of training. Identifying the etiology of stress fracture and its proper treatment prevents recurrence. Besides, evidence-based and supervised rehabilitation is indispensable for permanent remission of pain and return to sports to preinjury functional levels. The case series discusses the continuum of stress reaction to stress fracture in athletes, causes of stress fractures, their management, and return to sport. The paper aims to give a clear discussion about the management with rehabilitation guidelines for metabolic causes of stress fractures. Case Report: This study was a case series of five cases coming to Sports Medicine outpatient clinic of Sports Injury Centre, VMMC and Safdarjung Hospital, New Delhi, and physical medicine and rehabilitation outpatient clinic of Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow over a period of 1 year. The discussed cases are young Indian athletes, both male and females, who have presentation along the continuum of medial tibial stress syndrome (MTSS) to stress reactions and stress fracture. Conclusion: The findings of the paper highlight the significance of rehabilitation for individuals suffering from MTSS. Accurate diagnosis with targeted rehabilitation leads to quicker return to sports. The rehabilitation program comprises of identifying and treating the cause of stress fracture, removing any risk factors, biomechanical correction wherever indicated, structured exercise program, training in underwater treadmill, cyclical increase in loading, reducing activity every 3rd week.

Arthroscopic rotator cuff repair in active patients younger than 45 Years: a prospective analysis with a mean 5-year follow-up.

Background: To report clinical and activity-specific outcomes after arthroscopic rotator cuff repair (ARCR) for full-thickness supraspinatus tears in active individuals aged less than or equal to 45 years. The pre hoc hypothesis was that patients in this age group would demonstrate significant improvements in clinical outcomes following ARCR along with a significant improvement of athletic abilities. Methods: Patients were included in this study if they were (1) active individuals aged between 18 and 45 years at the time of surgery, (2) had a full-thickness rotator cuff tear of the supraspinatus tendon with or without anterior or posterior extension, and (3) underwent ARCR. Preoperative and postoperative patient-reported outcomes scores including the American Shoulder and Elbow Surgeons (ASES) score; Disabilities of Arm, Shoulder and Hand; Single Assessment Numeric Evaluation; and Short Form-12 Physical Component Summary were prospectively collected and postoperative patient satisfaction (scale of 1-10) was recorded at a minimum of 2 years postoperatively. Attainment of the minimal clinically important difference and patient acceptable symptom state for the ASES was calculated. Athletic activity-specific outcomes and return to activity were investigated prospectively via a custom-made comprehensive questionnaire. Results: Between November 2005 and June 2020, of 1149 RCRs performed by the senior author, 54 patients (mean age 40.9 years, 13 female; follow-up 69.7 ± 35.2 months in a range of 24.6-179.6 months) were included into the outcomes analysis. Of those, 4 patients (7.4%) had progressed to revision RCR. At a follow-up of 5.8 years, outcome scores had significantly improved compared to preoperative baselines (ASES 55.6 ± 13.8 to 90.1 + 15.8; P < .001; Disabilities of Arm, Shoulder and Hand 38.9 ± 18.4 to 11.9 ± 17.1; P < .001, Single Assessment Numeric Evaluation 60.7 ± 22.7 to 79.3 ± 27.6; P = .001, Short Form-12 Physical Component Summary 41.6 ± 8.3 to 51.9 ± 9.0; P ≤ .001). Ninety three point six percent of the patients reached the minimal clinically important difference and 72.6% reached the patient acceptable symptom state. Median satisfaction was 9.5/10. Eighty six percent of the patients returned to sports, while 67% of the patients returned to a similar level compared to preoperatively. All sport-specific metrics such as shoulder strength and endurance (P < .001), intensity (P < .001), and impairments from pain affecting speed (P = .002), endurance (P = .002), and competition (P < .001) significantly improved postoperatively. Conclusion: ARCR of full-thickness rotator cuff tear in active individuals aged 45 years or less results in a clinically relevant improvement of outcomes, function, and quality of life at a minimum of 2 years and mean 5.8-year follow-up with a low rate of revision. While 86% of patients were able to return to activity and sport-specific outcome metrics significantly and substantially improved compared to preoperatively, a return to preinjury levels was not reliably achieved in all patients, with particular limitations observed in overhead active individuals. The data support the hypothesis that patients in this age group demonstrate significant improvements in clinical outcomes following ARCR along with significant improvements in athletic abilities.

Eight of ten patients return to daily activities, work, and sports after total knee arthroplasty.

BACKGROUND: Besides return to work (RTW) and return to sports (RTS), patients also prefer to return to daily activities (RTA) such as walking, sleeping, grocery shopping, and domestic work following total knee arthroplasty (TKA). However, evidence on the timelines and probability of patients' RTA is sparse. AIM: To assess the percentage of patients able to RTA, RTW, and RTS after TKA, as well as the timeframe and influencing factors of this return. METHODS: A retrospective cohort study with prospectively collected data was conducted at a medium-sized Dutch orthopedic hospital. Assessments of RTA, RTW, and RTS were performed at 3 mo and/or 6 mo following TKA. Investigated factors encompassed patient characteristics, surgical characteristics, and preoperative patient-reported outcomes. RESULTS: TKA patients [n = 2063; 66 years old (interquartile range [IQR]: 7 years); 47% male; 28 kg/m2 (IQR: 4 kg/m2)] showed RTA ranging from 28% for kneeling to 94% for grocery shopping, with 20 d (IQR: 27 d) spent for putting on shoes to 74 d (IQR: 57 d) for kneeling. RTW rates varied from 62% for medium-impact work to 87% for low-impact work, taking 33 d (IQR: 29 d) to 78 d (IQR: 55 d). RTS ranged from 48% for medium-impact sports to 90% for low-impact sports, occurring within 43 d (IQR: 24 d) to 90 d (IQR: 60 d). One or more of the investigated factors influenced the return to each of the 14 activities examined, with R² values ranging from 0.013 to 0.127. CONCLUSION: Approximately 80% of patients can RTA, RTW, and RTS within 6 mo after TKA. Return is not consistently influenced by predictive factors. Results help set realistic pre- and postoperative expectations.

Association of Patient-Surgeon and Patient-Physical Therapist Relationships With Return to Sports After ACL Reconstruction: The Untested Dimension in Outcome Assessments.

Background: The Quality of Patient-Surgeon Relationship (QPASREL) is an 11-item questionnaire developed and validated to assess the relationship between practitioners and patients on recovery and return to work after surgery. Purpose: To evaluate the association of patient-surgeon relationship (PSR) and patient-physical therapist relationship (PPR), as measured by QPASREL, with a patient's return to sports (RTS) after anterior cruciate ligament reconstruction (ACLR). Study Design: Case-control study; Level of evidence, 3. Methods: This study targeted patients who underwent primary ACLR at a specialized sports surgery referral center between January and May 2021. Patients who had revision surgery, multiligamentous knee injury, and sedentary status were excluded from the study. Patients were grouped based on ability to RTS at the preinjury level 1 year postoperatively (RTS group and no-RTS group). The primary outcome was rate of RTS at 1 year postoperatively, and the primary dependent variables were the quality of PSR and PPR as measured by QPASREL scores at 6-month intervals. Secondary outcomes were the correlation and discriminative capacity of the QPASREL compared with the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI) scores (collected at 6-month intervals). Results: The study included 243 patients. Patients in the RTS group exhibited a higher mean PPR QPASREL score (36.6 ± 5.1) compared with no-RTS patients (34.8 ± 5.2; P = .01) as well as a higher mean PSR score (35.7 ± 5.1) compared with no-RTS patients (33.8 ± 5.9; P = .01). Multivariate analysis showed that every 5-point increase in the QPASREL scores for PPR and PSR resulted in a 39% (odds ratio [OR] = 1.39; P = 0.014) and 35% (OR = 1.35, P = 0.021) increased odds of RTS, respectively. A weak yet positive correlation was found between QPASREL and ACL-RSI. The predictive capacity of the QPASREL (area under the curve [AUC] = 0.60 for PPR and 0.61 for PSR), although significant, was less powerful compared with that of the ACL-RSI (AUC = 0.73). Conclusion: The quality of the PPR and PSR, as measured by QPASREL scores, demonstrated a significant association with RTS rates at 1 year after ACLR. A weak yet positive correlation was found between QPASREL and ACL-RSI.

Extracorporeal Shock Wave Therapy and the Handstand-Position Radiography for Proximal Humeral Epiphysiolysis in Elite Gymnasts: A Report of Two Cases.

We report two cases of proximal humeral epiphysiolysis in elite gymnasts. Both patients presented with shoulder pain during weight-bearing movements. The patient in case 1, treated with extracorporeal shock wave therapy (ESWT), exhibited rapid bone repair and pain relief, allowing an early return to competition. In the case 2 patient, humeral shortening was identified. Handstand-position radiography revealed compensatory scapular movements, negating the need for surgical intervention. These findings highlight ESWT's potential in promoting bone repair and the utility of handstand-position radiography in assessing humeral length. Both methods provide innovative treatment approaches for proximal humeral epiphysiolysis in gymnasts.

Mid- to long-term functional outcome and return to sport after elbow dislocation in bouldering: a clinical retrospective cohort study.

INTRODUCTION: Traumatic elbow dislocations are among the most common injuries in sport climbing. They occur most frequently in bouldering (a climbing discipline with strong upward trend often performed indoors) due to the typical low-height backward fall into crashpads. There is still no data about the functional outcome and return to sport of this typical bouldering injury. MATERIALS AND METHODS: All Patients with elbow dislocations due to a bouldering associated fall between 2011 and 2020 were identified retrospectively in our level I trauma centre. Trauma mechanisms, injury types and therapies were obtained. Follow-up was performed with an online questionnaire including sports-related effects, return to sport and the Elbow Self-Assessment Score (ESAS). RESULTS: 30 patients with elbow dislocations after bouldering accidents were identified. In 22 (73.3%) patients the injury was a simple dislocation. The questionnaire was completed by 20 patients. The leading mechanism was a low-height fall into crashpads. Surgical procedures were performed in every second patient. 18 patients (90%) reported return to bouldering after 4.7 ± 2.1 months. 12 patients (66.7%) regained their pre-injury level. Mid-/Long-term follow-up (mean 105 ± 37.5 months) showed excellent results in ESAS score (97.2 ± 3.9 points). Persistent limited range of motion or instability was reported by only 3 patients (15%). CONCLUSION: Most athletes are able to return to bouldering but only two thirds regain their pre-injury performance level in this demanding upper-extremity sport. The unique low-height trauma mechanism may create a false sense of security. Specific awareness and safety features should be placed for climbing athletes to reduce elbow injuries.

Return to sporting activities following long fusions to the pelvis in adult spinal deformity.

BACKGROUND CONTEXT: Returning to recreational sporting activities after adult spinal deformity (ASD) correction may significantly impact the patient's perceived quality of life. PURPOSE: This study sought to characterize participation in sporting activities before and after ASD surgery, and to identify factors associated with impaired return to sports. STUDY DESIGN: Cross-sectional survey and retrospective review of prospectively collected data. PATIENT SAMPLE: Patients who underwent posterior-only thoracolumbar ASD surgery between 2016 and 2021 with ≥1 year follow-up and ≥3 levels of fusion to the pelvis were included. OUTCOME MEASURES: Preoperative and postoperative participation in sports, timing of return to these activities, and reasons for limited sports participation postoperatively were assessed. METHODS: A survey was used to evaluate outcome measures. Differences in demographic, surgical, and perioperative variables between patients who reported improved, unchanged, or worsened activity tolerance were evaluated. RESULTS: Ninety-five patients were included (mean age: 64.3±10.1 years; BMI: 27.3±6.1 kg/m2; median levels fused: 7). The survey was completed at an average of 43.5±15.9 months after surgery. Sixty-eight (72%) patients participated in sports preoperatively. The most common sports were swimming (n=33, 34.7%), yoga (n=23, 24.2%), weightlifting (n=20, 21.1%), elliptical (n=19, 20.0%), and golf (n=11, 11.6%). Fifty-seven (83.8%) returned to at least one sport postoperatively, most commonly 6-12 months after surgery (45%). Elliptical had the highest rate of equal or improved participation (53%). Patients generally returned below their preoperative level to all other sports. Reasons for reduced sporting activities included physical limitation (51.4%), fear (20.0%), pain (17.1%), and surgeon advice (8.6%). There were no differences in the demographic, surgical, or perioperative characteristics between those who returned to sports at the same or better level compared with those who returned at a lower level. CONCLUSIONS: About 84% of patients successfully resumed sporting activities after undergoing fusion to the sacrum/pelvis for ASD. However, this return is typically at a lower level of participation than their preoperative participation, particularly in higher demand sports. Understanding trends in sporting activity may be valuable for counseling patients and setting expectations.

Association of Graft Maturity on MRI With Return to Sports at 9 Months After Primary Single-Bundle ACL Reconstruction With Autologous Hamstring Graft.

Background: The relationship between graft maturity on magnetic resonance imaging (MRI) and return to sports (RTS) after anterior cruciate ligament (ACL) reconstruction is unclear. Purpose: To compare signal-to-noise quotient (SNQ) values and ACL graft T2* (gradient echo) values between patients who did RTS and those who did not RTS (NRTS) after ACL reconstruction and to evaluate the predictive value of T2* mapping for RTS after ACL reconstruction. Study Design: Case-control study; Level of evidence, 3. Methods: At a minimum of 9 months after arthroscopic single-bundle ACL reconstruction with autologous hamstring tendon graft, 82 patients underwent RTS assessment as well as MRI evaluation. The patients were classified into RTS (n = 53) and NRTS (n = 29) groups based on the results of the assessment. The SNQ values in the proximal, middle, and distal regions of the graft and the T2* values of the graft were measured on MRI. The correlation between T2* values and RTS was assessed using Spearman correlation analysis. Receiver operating characteristic curves were constructed to compare the diagnostic performance, and the optimal T2* cutoff value for detecting RTS was determined based on the maximum Youden index. Results: At 9 months after ACL reconstruction, the proximal, middle, and mean SNQ values in the RTS group were significantly lower than those in the NRTS group (proximal: 17.15 ± 4.85 vs 19.55 ± 5.05, P = .038; middle: 13.45 ± 5.15 vs. 17.75 ± 5.75, P = .001; mean: 12.37 ± 2.74 vs 15.07 ± 3.32, P < .001). The T2* values were lower in the RTS group (14.92 ± 2.28 vs 17.69 ± 2.48; P < .001) and were correlated with RTS (r = -0.41; P = .02). The area under the curve of T2* was 0.79 (95% CI, 0.75-0.83), and the optimal cutoff value for T2* was 16.65, with a sensitivity and specificity for predicting failure to RTS of 67.9% and 88.2%, respectively. Conclusion: Study findings indicated that the SNQs (mean, proximal, and middle) and the T2* values of the graft in the RTS group were significantly lower than those in NRTS group. A T2* value of 16.65 was calculated to predict patients who failed RTS tests with a sensitivity of 67.9% and specificity of 88.2%.

Outcomes of Blood Flow Restriction Training After ACL Reconstruction in NCAA Division I Athletes.

Background: Blood flow restriction training (BFRT) is a safe and potentially effective adjunctive therapeutic modality for postoperative rehabilitation related to various knee pathologies. However, there is a paucity of literature surrounding BFRT in high-performance athletes after anterior cruciate ligament reconstruction (ACLR). Purpose: To (1) compare the overall time to return to sports (RTS) in a cohort of National Collegiate Athletic Association (NCAA) Division I athletes who underwent a standardized rehabilitation program either with or without BFRT after ACLR and (2) identify a postoperative time interval for which BFRT has the maximum therapeutic benefit. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 55 student-athletes who underwent ACLR between 2000 and 2023 while participating in NCAA Division I sports at a single institution were included in this study. Athletes were allocated to 1 of 2 groups based on whether they participated in a standardized postoperative rehabilitation program augmented with BFRT (BFRT group; n = 22) or completed the standardized protocol alone (non-BFRT group [control]; n = 33). Our primary outcome measure was time to RTS. The secondary outcome measure was handheld dynamometry quadriceps strength testing at various postoperative time points, converted to a limb symmetry index (LSI). Quadriceps strength was not tested between the BFRT and non-BFRT groups because of the limited amount of data on the control group. Results: The mean age at the date of surgery was 18.59 ± 1.10 years for the BFRT group and 19.45 ± 1.30 years for the non-BFRT group (P = .011), and the mean RTS time was 409 ± 134 days from surgery for the BFRT group and 332 ± 100 days for the non-BFRT cohort (P = .047). For the BFRT group, the mean quadriceps strength LSI increased by 0.67% (95% CI, 0.53%-0.81%) for every week of rehabilitation, and there was a significantly positive rate of change in quadriceps strength in weeks 13-16 compared with weeks 9-12 (ΔLSI, 8.22%; P < .001). Conclusion: In elite NCAA Division I athletes, a statistically significant delay was observed in RTS with BFRT compared with standardized physical therapy alone after undergoing ACLR. There also appeared to be an early window during the rehabilitation period where BFRT had a beneficial impact on quadriceps strength.

Return to Duty in Military Servicemembers After High Tibial Osteotomy Not Associated With Preoperative Radiographic Parameters : A Retrospective Analysis.

Background: Evidence on return to sports/work after high tibial osteotomy (HTO) is limited, especially in a young, high-demand population. Purpose: To (1) identify whether preoperative knee pathology or intraoperative correction was associated with successful return to duty (RTD) and (2) assess whether postoperative complications and reoperation were associated with failure to RTD. Study Design: Case series; Level of Evidence, 4. Methods: We performed a retrospective cohort study of a consecutive series of patients in the Military Health System aged 18 to 55 years with medial compartment osteoarthritis who underwent HTO between 2003 and 2018. Concomitant meniscal and cartilage procedures were included, while cases with concomitant ligamentous procedures were excluded. The inclusion criteria were as follows: active-duty military status, minimum 2-year follow-up, preoperative knee radiographs, and pre- and postoperative long-leg alignment radiographs. Preoperative Kellgren-Lawrence grades and pre- and postoperative hip-knee-ankle angles were measured. The primary outcome was RTD. Failure was defined as knee-related medical separation from the military or conversion to total knee arthroplasty. The secondary outcome was reoperation. Results: A total of 55 HTOs were performed in 50 patients who met the inclusion criteria, with a mean age of 39 years old (range, 22.8-55 years). The mean follow-up was 5 years (range, 2.1-10.7 years). Ten knees (18.2%) failed HTO (1 conversion to total knee arthroplasty, 9 medical separations), 15 additional knees (27.3%) had permanent activity restrictions, and 30 knees (54.5%) returned to duty without restrictions. Reoperation occurred in 36.4% of knees and was associated with medical separation (P = .039). Younger age was associated with medical separation (P = .003) and permanent restrictions (P = .006). Patients with a postoperative varus deformity of >5° were more likely to undergo medical separation (P = .023). Conclusion: In a young, high-demand population, HTO succeeded in returning 54.5% of knees to full duty without restriction despite 36.4% of knees requiring reoperation. Residual varus deformity or reoperation was associated with lower RTD rates. No association was identified between RTD and preoperative osteoarthritis grading or deformity.

Postoperative recreational sports and subjective shoulder function: a comprehensive analysis following intramedullary stabilization of displaced midshaft clavicular fractures.

Introduction Sports-related outcomes and the role of recreational sports activities for shoulder function after intramedullary stabilization (IMS) of displaced midshaft clavicular fractures (DMCFs) in the general population are not well known. In this study, we aimed to determine the sport-related outcomes (return-to-sports [RTS] rate, type of sports, time until RTS, and intensity) and to explore the role of sports after IMS of DMCFs. Materials and Methods This single-center, retrospective, cohort study included patients who underwent IMS of DMCFs between 2009 and 2022 at a Level II trauma center in Germany, experienced no major complications, and had completed at least 1 year of follow-up. Propensity score matching was conducted to obtain a balanced sample of patients who did not engage (cases) and engaged (controls) in postoperative sports activities by adjusting for age and fracture complexity. Groups were compared to assess the impact of regular sports activities on subjective shoulder functioning at follow-up, as evaluated using the Disabilities of the Arm, Shoulder, and Hand and Oxford Shoulder Score (OSS) questionnaires, after controlling for the patient- (i.e., sex and smoking) and treatment- (i.e., surgery duration and physical therapy) factors. Results Among the 199 patients included, the RTS rate was 97.5%, and 160 patients practiced regular postoperative activity, mostly in the same sport and intensity. In the matched cohort (39 cases and 39 controls), practicing regular sports activities postoperatively was the only independent factor associated with a higher OSS in the multiple regression analysis (unstandardized regression coefficient = 2.40; Bias-corrected and accelerated 95% confidence interval [0.28, 4.69]). Conclusions The sport-related outcomes after IMS of DMCFs in our cohort were comparable to those achieved after plate osteosynthesis, and IMS reported in the literature. Recreational sports activities benefitted subjective shoulder function, thereby encouraging further research and potentially influencing management policies. Level of evidence Grade IV - a retrospective observational cohort study.

Return to sports after an ACL reconstruction in 2024 - A glass half full? A narrative review.

A successful return to sports (RTS) after an anterior cruciate ligament reconstruction (ACLR) is multifactorial, and therefore difficult and challenging. Unfortunately, low percentages of patients RTS, and for those who succeed, one-fifth of patients will sustain a second ACL injury. Over the past years, test batteries were developed to assess whether patients can RTS with a low risk for a second ACL injury risk. Low rates of patients who meet RTS criteria were found, coupled with the insufficiency of current RTS test batteries in predicting second ACL injuries suggesting poor sensitivity. The result of an RTS test is likely to reflect the content of a rehabilitation program, raising critical questions regarding what we are offering patients within the rehabilitation programme. Are we preparing our patients well enough for the high demands of complex situations within pivoting team sports? This narrative review offers insights from key lessons of the last 15 years on 1) RTS testing, 2) the content of rehabilitation, and 3) the RTS continuum, all from a "helicopter perspective".

Sex-specific analysis in patients undergoing Talar OsteoPeriostic grafting from the Iliac Crest (TOPIC) for large osteochondral lesions of the talus.

PURPOSE: The purpose of the present study is to assess the gender-specific differences in the presentation and outcomes following Talar OsteoPeriostic grafting from the Iliac Crest (TOPIC) between male and female patients. METHODS: A prospective comparative analysis was performed comparing consecutive female and male patients having been treated by the press-fit TOPIC procedure. Clinical comparative assessment preoperatively and at 12 months of follow-up included determination of the Numeric Rating Scale (NRS) scores for pain during walking (primary outcome), at rest and during stair-climbing. The Foot and Ankle Outcome Score (FAOS) was also assessed. A computed tomography (CT) scan was performed for lesion size, morphology and localization determination preoperatively as well as 10-12 weeks postoperatively to assess the union of the osteotomy site and at 1 year postoperatively to assess consolidation of the graft as well as intra-graft cyst development. RESULTS: A total of 48 patients (30 women, 18 men) were eligible for inclusion. Both men and women demonstrated significant functional improvements postoperatively concerning the clinical outcomes with no significant differences between men and women (n.s.) except for a significantly greater improvement in postoperative FAOS pain scores in women. Men presented with OLTs significantly larger in both surface area (208 mm2 for males versus 155 mm2 for females, p < 0.05) as well as lesion volume (3.0 cm3 for males versus 1.8 cm3 for females, p < 0.05). At 1-year postoperatively, all patients showed graft consolidation. Cyst formation was present in 11 females (37% of the group) and 10 males (59% of the group), respectively (n.s.). CONCLUSION: Both males and females showed clinically relevant improvements in the clinical outcomes after undergoing the TOPIC procedure with significant differences in preoperative lesion size. The TOPIC procedure is a good treatment strategy for large OLTs in both men and women. LEVEL OF EVIDENCE: Level III, comparative prospective clinical cohort.

Reliability and responsiveness of the Swedish short Hip-RSI.

Purpose: The aim of this study was to examine test-retest reliability and responsiveness of the short version (6-item) Hip Return to Sport after Injury (Hip-RSI) scale in patients following hip arthroscopy. Methods: The study included 100 hip arthroscopy patients responding to a digital survey including the short version (6-item) Hip-RSI, International Hip Outcome Tool (short version) (iHOT-12) and RTS status 3, 6 and 9 months following surgery. The Hip-RSI was administered twice at 3-month follow-up. Test-retest reliability was evaluated using intraclass correlation coefficients. Responsiveness was tested by correlations between changes in Hip-RSI and iHOT-12 scores and by comparing change in Hip-RSI scores of patients who progressed on the return to sport (RTS) continuum (from return to any sport to return to performance) to patients who did not, using independent samples t-tests. Results: Hip-RSI was found to have excellent test-retest reliability on the individual (intraclass correlation coefficient, ICC [95% confidence interval, CI]: 0.90 [0.83-0.94]) and group level (ICC [95% CI]: 0.95 [0.91-0.97]) with a standard error of measurement of 5.53 and smallest detectable change of 15.3 on the individual and 2.2 on the group level. Hip-RSI was found responsive to change through positive correlations of changes in scores with changes in iHOT-12 scores from 3 to 6 months (r [95% CI]: 0.51 [0.35-0.65]; p < 0.001) and from 3 to 9 months following arthroscopy (r [95% CI]: 0.61 [0.57-0.79); p < 0.001). Further responsiveness was shown by significant mean changes in scores among patients that progressed on the RTS-continuum (3-6 months: 8.6 [95% CI: 3.8- 13.5); 3-9 months: 12.6 [5.6-19.7]). Conclusion: The short version (6-item) Hip-RSI demonstrated excellent test-retest reliability and responsiveness to change in the evaluation of psychological readiness to RTS following hip arthroscopy. Level of Evidence: Level II.

Unicompartmental knee replacement: controversies and technical considerations.

BACKGROUND: Unicompartmental knee replacement (UKR) is one of the effective interventions for the treatment of symptomatic knee osteoarthritis. Moreover, it has multiple advantages over total knee arthroplasty (TKA), including reduced intraoperative blood loss, decreased risk of transfusion, and faster recovery. This study aimed to discuss critical technical considerations regarding UKR and some of the controversies and updates. METHODS: We conducted a review to provide an overview of the controversies and technical considerations about UKR in several aspects. Only peer-reviewed articles were included, up to December 2023 using PubMed, Google Scholar, ERIC, and Cochrane database for systematic reviews databases. RESULT: UKR is associated with superior patient-reported clinical and functional outcomes, as well as shorter hospital stays, fewer postoperative complications, and revealed favorable outcomes in patients' return to sport. The choice between mobile- and fixed-bearing prostheses depends, in part, on the surgeon's preference. The mobile-bearing UKR is a less constrained prosthesis and can potentially result in less wear, but it is more technically demanding. While no significant difference between mobile-bearing versus fixed-bearing prostheses, cementless is superior to cemented design. Furthermore, UKR can be a good alternative for high tibial osteotomy (HTO) and still can be considered after a failed HTO. Lastly, recent reviews have shown a revision rate comparable to that of TKA. This is probably influenced by Improved comprehension of the best indications, patient selection criteria, as well as of the design, materials, and technological advances. CONCLUSION: UKR treatment for unicompartmental knee osteoarthritis is secure and effective. Based on clinical and functional outcomes, decreased morbidity and mortality, and cost-effectiveness, long-term studies suggest that UKR is superior to TKA. Further investigation in this area is warranted.

Return to Sports and Clinical Results After All-Arthroscopic Biceps Tenodesis Using a 2.7-mm Knotless PEEK Suture Anchor.

Background: The long head of the biceps tendon (LHBT) is a well-known source of pain in the shoulder, especially in active patients. Purpose: To evaluate the outcomes and return-to-sports rate after all-arthroscopic suprapectoral tenodesis of the LHBT using a small knotless anchor. Study Design: Case series; Level of evidence, 4. Methods: In this retrospective study, 27 patients-who underwent all-arthroscopic tenodesis of the LHBT using a 2.7-mm knotless polyether ether ketone anchor-were evaluated. Sports activities, the return-to-sports rate, and other sports-related parameters (eg, pain during sports, level of sports) were examined. Sports-related data, the Constant score with isometric force (at 90° of abduction in the scapular plane), the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST) score, the visual analog scale (VAS) score for satisfaction, range of motion, and the presence of a Popeye deformity were assessed at a mean follow-up of 15.3 ± 8.7 months. The data were initially analyzed using descriptive statistics. Results: The postoperative ASES, Constant, and SST scores were 81.61, 85.74 and 8.85, respectively. Of the 27 patients, 4 patients (14.8%) showed a Popeye deformity. Preoperatively, 25 patients (92.6%) participated regularly in some type of sports activity. All 25 patients (100.0%) were able to return to sports activities after surgery. 24 (96.0%) returned to the same level preoperatively, with 88.0% (22/25) within 6 months. Patient satisfaction with the outcome was high (VAS score: 2.15 ± 2.78). Neither bicipital groove pain nor cramping was reported. There were no signs of osteolytic bone around the anchor or a fracture of the humeral bone. Conclusion: Our clinical results after using a 2.7-mm knotless anchor for LHBT tenodesis as well as the return-to-sports rate were satisfying. Using an anchor this size can lower the risk of cortical bone damage and therefore the risk of fractures of the humeral head while still enabling patients to perform at a high level.
