Minimally Invasive Quadricepsplasty Using the Adolphson-Cerqueira Technique: A Retrospective Study after 1-Year of Follow-up.

Knee stiffness limits activities of daily living with treatment having no gold standard technique currently. We present follow-up data 1-year after quadricepsplasty using the Adolphson-Cerqueira technique for the treatment of knee stiffness in a Brazilian population sample. This retrospective study included patients who underwent a quadricepsplasty using the Adolphson-Cerqueira technique between January 2006 and March 2023 at our institution. The inclusion criteria were: (1) Knee stiffness with a range of motion <70°; (2) Patellar excursion ≥2 mm on physical examination; (3) Available knee radiography in the anteroposterior and lateral views; and (4) A follow-up at 1 year postoperatively. The Judet Classification was used to assess the outcome of the quadricepsplasty. Sixty-seven patients were included. The results were 6% poor, 31.3% fair, 44.8% good, and 17.9% excellent according to the Judet Classification. A correlation was observed between age and the gain in range of motion at the 1-year postoperative follow-up, and between the gain in range of motion intraoperatively and that at the 1-year follow-up. There were five cases of complications (7.46%): one of patellar fracture, three of quadriceps tendon rupture, and one of avulsion fracture in the superior pole of the patella. Quadricepsplasty using the Adolphson-Cerqueira technique produced satisfactory results overall for improving knee joint stiffness and had a complication rate comparable with other currently used techniques. Loss of knee range of motion remains a difficult problem without there being a clear gold standard in treatment. Many different options are described in the literature. We provide a further option with follow-up results. Cerqueira FS, Silva L, Kropf LL, et al.

Rotating Hinge Revision Total Knee Arthroplasty Provides Greater Arc of Motion Gains for Patients Who Have Severe Arthrofibrosis

BackgroundArthrofibrosis is a common postoperative total knee arthroplasty (TKA) complication that results in limited range of motion (ROM). There is limited literature on outcomes after revision TKA (rTKA) for arthrofibrosis based on preoperative ROM restriction. The aims of this study were to: (1) examine ROM trajectory after rTKA for arthrofibrosis patients who have severe versus nonsevere limitations; (2) compare ROM gains and final arc of motion (AOM) between severe and nonsevere cohorts; (2a) compare ROM gain in a severe cohort treated with a rotating hinge (RH) versus a non-RH (NRH) construct; and (3) assess the impact of arthrofibrosis severity on patient-reported outcome measures. MethodsPatients were divided into 2 groups: group A had preoperative ROM < 70° (severe), and group B had preoperative ROM > 70° (non-severe). Patients were assessed clinically using AOM gain, absolute ROM, Knee injury and Osteoarthritis Outcomes Score for Joint Replacement, lower extremity activity scale, and pain scores. Postoperative gains in AOM were compared between both groups. ResultsA total of 56 rTKAs (group A (severe): n = 36, group B (non-severe): n = 20) were performed for patients who have postoperative fibrosis. Group B had better ROM at the 1-year time point (group B: 95.9 ± 22.5 degrees versus group A: 83.2 ± 25.7 degrees). Group A had significantly better improvement in absolute AOM than group B (31.1 ± 20.9 versus 11.4 ± 25.0 degrees, P < 0.01). The RH group demonstrated significantly better absolute AOM gain than the NRH group (41.3 ± 19.4 versus 18.3 ± 15.2 degrees, P < 0.001). However, there were no significant differences in patient-reported outcome measures between groups A and B or between RH and NRH groups at the final follow-up. ConclusionsFinal ROM achieved between severe and nonsevere arthrofibrosis groups was similar, and patients who have severe arthrofibrosis can expect greater absolute ROM gains and similar functional outcomes than nonsevere arthrofibrosis patients. The RH rTKAs provided greater AOM gains for patients who have severe arthrofibrosis, with equivalent functional outcomes to non-RH implants. For severe arthrofibrosis patients, RH designs provided twice the overall ROM gain; however, longer follow-up is necessary to determine whether RH designs have inferior overall implant survivorship.

Glenohumeral Internal Rotation Deficit in Young Asymptomatic Elite Swimmers.

Glenohumeral internal rotation deficit (GIRD) may affect overhead athletes and contribute to shoulder injury. To assess data on passive shoulder range of motion (ROM) in young elite swimmers and to determine the prevalence of anatomical and pure GIRD (aGIRD and pGIRD, respectively) in a large sample size of asymptomatic elite swimmers with a new classification method. Cross-sectional study. Research laboratory. A total of 752 asymptomatic elite swimmers were recruited by voluntary participation (391 males and 361 females; mean age, 15.88 ± 2.31 years). Passive glenohumeral rotational ROM was measured bilaterally to investigate the prevalence of aGIRD and pGIRD. Evaluations were performed with athletes at rest before any training or competition. Glenohumeral internal rotation deficit and associated aGIRD and pGIRD in elite youth swimmers by identifying a standard classification procedure. Glenohumeral internal rotation deficits were found in 136 participants (18.1%). Anatomical GIRD was present in 28 cases (3.7%), whereas pGIRD was observed in 108 cases (14.4%). No significant differences were found regarding GIRD between sex, age, age group, years of training, breathing side, and distance. Swimmers with pGIRD showed significantly less dominant internal rotation, total ROM, and external rotation gain (P < .01) than swimmers with aGIRD; conversely, swimmers with aGIRD showed significantly less nondominant internal rotation, external rotation, and total ROM than swimmers with pGIRD (P < .01). Glenohumeral internal rotation deficit is a relatively common condition in asymptomatic elite youth swimmers; as to not overestimate this condition, aGIRD and pGIRD have to be distinguished. Although they play a role, the respiratory side, dominant limb, and crawl did not have a significant impact on an elite swimmer with GIRD.

Poster 161: Musculoskeletal Adaptations to Baseball Pitching Differ Markedly Between Righthand Dominant Versus Lefthand Dominant Pitchers

Objectives: Musculoskeletal adaptations on the dominant arm of baseball pitchers are typically (1) a gain in glenohumeral external rotation (ER) range of motion (ROM), (2) a loss of glenohumeral internal rotation (IR) ROM, (3) posterior shoulder tightness, (4) weakness in the empty can test, and (5) increased IR strength. The purpose of this study was to determine if these adaptations differed between righthand dominant (RHD) versus lefthand dominant (LHD) pitchers. Based on recent work it was hypothesized that ROM adaptations would be less apparent in LHD pitchers, but strength adaptations would not differ between RHD and LHD pitchers. Methods: Shoulder ROM and strength were measured in 327 baseball pitchers in preseason screening (91 were tested on more than one season, 418 player-seasons, 322 RHD vs. 96 LHD). There were 157 youth pitchers (age 11-15 yr) 146 adolescent pitchers (age 16-17 yr) and 115 adult pitchers (age 18-24 yr). ER ROM, IR ROM and posterior shoulder ROM (Tyler test) were measured with a digital level. Empty can, ER, IR and scapular retraction strength were measured with a hand-held dynamometer. Differences between the dominant and nondominant arms, between RHD and LHD pitchers, and between age groups, were assessed using mixed model analysis of variance (mean and SD reported). Results: ROM Adaptations RHD pitchers had 11±10° more ER ROM on the dominant versus nondominant arm (P&lt;0.001) but LHD pitchers had no ER ROM difference (0±10°, P=0.685). The difference in ER ROM between RHD and LHD pitchers (P&lt;0.001) was unaffected by age (P=0.829). IR ROM loss on the dominant versus nondominant arm for RHD pitchers (10±11°) was greater (P&lt;0.001) than for LHD pitchers (5±10°). This difference was apparent for youth pitchers (RHD 9±9° vs. LHD 1±9°, P&lt;0.001) and adolescent pitchers (RHD 12±10 vs. LHD 5±11°, P&lt;0.001) but not for adult pitchers (RHD 9±14° vs. LHD 8±10°, P=0.863; RHD vs. LHD by Age Group P=0.040). Total ROM (ER+IR ROM) adaptations also differed between RHD and LHD pitchers (P&lt;0.001) and this effect was more apparent in the adult pitchers (Age Group by RHD vs. LHD P=0.027): RHD adult pitchers had a 4±15° gain in total ROM on the dominant side (P=0.007) while LHD adult pitchers had a 7±10° loss in total ROM on the dominant side (P=0.002). Posterior shoulder tightness on the dominant side was affected by arm dominance and age (P=0.038); for youth and adolescent pitchers there was no difference between RHD and LHD pitchers (youth RHD 6±13° vs. LHD 10±11°, P=0.156; adolescent RHD 5±10° vs. LHD 8±15°) but for adult pitchers, posterior shoulder tightness was greater for RHD versus LHD pitchers (6±8° vs. 1±11°, P=0.032). Strength Adaptations For the empty can test, RHD pitchers were weaker on the dominant versus nondominant arm (5±15%, P&lt;0.001) while there was no difference between the dominant and nondominant arms for LHD pitchers (3±16% stronger on dominant side P=0.100; RHD vs. LHD P&lt;0.001). For IR strength, RHD pitchers were stronger on the dominant arm (7±17%, P&lt;0.001) while there was no difference between the dominant and nondominant arms for LHD pitchers (2±21% P=0.360; RHD vs. LHD P=0.032). By contrast, for scapular retraction strength, LHD pitchers were stronger on the dominant arm (6±19%, P=0.007) while there was no difference between the dominant and nondominant arms for RHD pitchers (0±15% P=0.723; RHD vs. LHD P=0.003). Dominant versus nondominant ER strength was not different between RHD and LHD pitchers (P=0.323). Conclusions: The typical strength and ROM adaptations seen in baseball pitchers were mostly absent, or diminished, in LHD pitchers, but with some age dependent effects for ROM. Adult RHD pitchers had IR ROM loss and posterior shoulder tightness, but paradoxically adult LHD pitchers had IR ROM loss without associated posterior shoulder. The opposite was the case for youth and adolescent pitchers, with LHD pitchers having posterior shoulder tightness in the absence of IR ROM loss. Differences in strength adaptations between RHD and LHD pitchers have not been reported previously. Epidemiological studies examining the role of strength and ROM in injury risk for baseball pitchers have not previously accounted for differences between lefthanded and righthanded pitchers.

Arthrofibrosis is a common but poorly defined complication in multiligament knee injuries: a systematic review

PurposeThe purpose of this study is to systematically review multiligament knee injury (MLKI) outcome studies to determine definitions of arthrofibrosis (AF) and provide information about incidence, management as well as potential risk factors.MethodsA systematic literature search was performed (PubMed and Cochrane library) following the PRISMA guidelines of operatively treated MLKI (Schenck II–IV) studies reporting the incidence of AF. Twenty-five studies met the inclusion criteria. Injury pattern, timing of surgery, surgical technique, treatment of AF, rehabilitation programs and PROMS were inquired. Risk of bias and quality of evidence were assessed using the Coleman methodological score.ResultsTwenty-five studies with a total of 709 patients with a mean age of 33.6 ± 4.8 years were included and followed 47.2 ± 32.0 months. The majority of studies (22/25) used imprecise and subjective definitions of AF. A total of 86 patients were treated for AF, resulting in an overall prevalence of 12.1% (range 2.8–57.1). Higher-grade injuries (Schenck III–IV), acute treatment and ROM (range of motion) limiting rehabilitation programs were potential risk factors for AF. The time from index surgery to manipulation anesthesia (MUA) and arthroscopic lysis of adhesions (LOA) averaged at 14.3 ± 8.8 and 27.7 ± 12.8 weeks. Prior to MUA and LOA, the ROM was 51.7° ± 23.5 and 80.2° ± 17.0, resulting in a total ROM gain after intervention of 65.0° ± 19.7 and 48.0° ± 10.6, respectively; with no reports of any complication within the follow-up. The overall methodological quality of the studies was poor as measured by the Coleman score with average 56.3 ± 12.5 (range 31–84) points.ConclusionsAF is a common but poorly defined complication particularly in high-grade MLKI. Early postoperative and intensified physiotherapy is important to reduce the risk of AF. MUA and LOA are very effective treatment options and result in good clinical outcome. Prospective studies with bigger study population are needed to optimize treatment algorithms of further patients after MLKI.The protocol of this systematic review has been prospectively registered with PROSPERO (CRD42021229187, January 4th, 2021).

Complications of First Tarsometatarsal Joint Arthrodesis

Category: Bunion Introduction/Purpose: Hallux valgus, a term introduced by Carl Hueter (1) to define static subluxation of the first metatarsophalangeal joint characterized by lateral deviation of the hallux and medial deviation of the first metatarsal, (1,2) is a disease for which different corrective surgical techniques can be used, depending on its severity. First tarsometatarsal joint (TMTJ) arthrodesis, also known as Lapidus, is one of the surgical procedures used in the treatment of severe hallux valgus, among other alterations (3-5). Despite the high satisfaction rate and high corrective power, this technique is not without complications. The main com- plications include delayed union, malunion, chronic edema, persistent pain, nonunion, joint stiffness, recurrent deformity, and varus deformity (6). However, there is little scientific evidence of these complications after first TMTJ arthrodesis. The purpose of this study was to report the complications of first TMTJ arthrodesis performed by orthopedic surgeons specializing in foot and ankle surgery. Methods: This study was approved by the institutional research ethics committee and registered at Plataforma Brasil. We evaluated 16 patients undergoing first TMTJ arthrodesis, who denied any comorbidities. The procedures were performed by 7 different orthopedic surgeons specializing in foot and ankle surgery with different levels of experience, ranging from 1 to 29 years of experience in the field. All patients underwent arthrodesis with plates and screws. The plate was placed on the plantar aspect of the first tarsometatarsal in 4 patients and on the anteromedial aspect in all other patients. The dorsomedial incision was used, centered on the first TMTJ, for the 12 cases in which the plate was positioned in the dorsomedial region, and the medial incision was used for the 4 cases in which the plate was positioned on the plantar aspect. Also, articular cartilage was resected using a chisel and microperforations. All 16 patients were followed up in an outpatient clinic at 1, 2, 4, 6, 12, and 24 weeks postoperatively. The follow-up visits included the evaluation of anteroposterior, lateral, and oblique radiographs of the foot, clinical alignment of the hallux, and patients' signs and symptoms. For all patients, postoperative care included immobilization in a non-weight-bearing cast for 4 weeks, initiation of physical therapy with range of motion gain at 4 weeks, and partial weight- bearing at 6 weeks Results: We evaluated 16 patients operated on over an 18-month period (from February 2017 to August 2018). We measured preoperative and postoperative hallux valgus and intermetatarsal angles (Table 1). Eight patients had either major or minor complications (Table 2). Three patients had recurrent deformity (1 with associated nonunion), 2 had delayed union, 2 had hardware loosening (Figure 1) - 1 with associated nonunion (Figure 2), and 1 had wound dehiscence. Conclusion: Based on our study, we can conclude that first TMTJ arthrodesis requires greater care in choosing the surgical technique for the treatment of hallux valgus. In addition, some points should be considered to avoid complications as much as possible, such as the use of implants to increase stability, instruments for better articular cartilage resection, and improvement in the correction of the pronation deformity of the hallux. The limitations of our study prevent us from drawing a robust conclusion and defining consistent parameters related to the main factors that may affect the various complications described in the study. Therefore, we believe that data are still scarce to provide a concrete basis, and further studies are needed to make substantiated conclusions.

81. Mobility parameters in two level-lumbar TDR vs hybrid construct: clinical results in 235 patients

<h3>BACKGROUND CONTEXT</h3> Lumbar total disc replacement (TDR) is a treatment option with 30 years experience and extensive publications on clinical results. However, there are few publications on mid- and long-term mobility. There is also sparse literature on the quality of mobility or the difference between L4-S1 2-level TDR vs TDR/ALIF hybrid constructs. <h3>PURPOSE</h3> To measure mobility parameters in flexion-extension for two groups (L4-S1 TDR vs hybrid); compare motion at L4–L5; participation of pelvis mobility; global lumbar motion; and flexion-extension effectiveness by measuring L1 race. Besides determining the difference of mobility between TDR and hybrid, we discussed potential compensations above and below L5-S1 fusion/L4-L5 TDR, as compared to two-level TDR. <h3>STUDY DESIGN/SETTING</h3> Retrospective clinical study. <h3>PATIENT SAMPLE</h3> This study included 235 patients, operated between 2003-2013: 170 patients received 2-level TDR (TDR group) and 65 received L4-L5 TDR and L5-S1 ALIF (hybrid group). <h3>OUTCOME MEASURES</h3> Data collected included radiographic, neurological/physical assessment, self-evaluation using the Oswestry Disability Index (ODI) and visual analog back and leg pain scores (VAS). Complication, reoperation/revision rates, and perioperative data points were also assessed. <h3>METHODS</h3> Both groups were equivalent in age, body habitus and preoperative clinical parameters (ODI, VAS). Patient selection for evaluation was based on presence of clinical success criteria and pre- and postoperative sagittal X-rays and dynamic flexion-extension films at minimum 24-month follow-up. Pelvic parameters (Incidence, Pelvic Tilt, Sacral Slope) were measured. L4-L5 and L5-S1 flexion-extension range of motion (ROM) was measured pre- and postoperatively. Pelvic motion was determined by measuring sacral slope in flexion-extension. The influence on lumbar lordosis (L1-S1) was also analyzed. To show the effect the lumbopelvic complex has on global motion, we measured L1 race (flexion-extension L1 ROM). <h3>RESULTS</h3> The absolute motion and relative gain of 2-level TDR shows its superiority over hybrid constructs in all measured parameters. When L5-S1 is fused, there is no compensation from pelvic motion to overcome the loss of mobility. TDR group shows a pelvi-femoral ROM gain of 16.77°, vs a gain of only 6.11° in the Hybrid group. L5-S1 fusion also reduces L4-L5 TDR mobility in Hybrid group, compared to 2-level TDR, and decreases flexion compared to baseline. There is a mean reduction in ROM of 1.53° in Hybrid group vs 20.02° gain in TDR group. L1 race also reflects the superiority of 2-level TDR vs hybrid with a gain of 32.58° in TDR vs 4.68° in hybrid, demonstrating that reduced global motion is principally due to loss of L5-S1 motion. <h3>CONCLUSIONS</h3> This comparison between 2-level TDR and hybrid demonstrates a lack of compensation through lumbar mobility and pelvic motion when L5-S1 is fused, and debunks these preconceived ideas. Although clinical measures of activity (ODI) and pain (VAS back and leg pain) are equivalent between the groups, functional superiority of 2-level TDR is confirmed. Two new ROM parameters introduced here—pelvic motion and L1 race—must be integrated in all ROM studies as they quantify pelvic participation in mobility and the functional effectiveness of motion preservation. In this first long-term comparison of mobility between 2-level TDR vs L4-S1 hybrid, 2-level TDR demonstrates overall superiority. Consequently, 2-level TDR must be systematically indicated whenever TDR is indicated for both levels, and accepted as the "gold standard" for reimbursement purposes. <h3>FDA DEVICE/DRUG STATUS</h3> Prodisc L 1- and 2-level (Approved for this indication), Prodisc L hybrid constructs (Not approved for this indication)

Incidence and effectiveness of manipulation under anaesthesia for stiffness following primary total knee arthroplasty.

There are various modalities of cor- rection of stiffness following total knee arthro-plasty. Manipulation under anaesthesia (MUA) is generally indicated for people who fail to achieve their pre operative range of motion at 12 weeks. The purpose of this study was to determine: (1) the effect of MUA on Flexion arc (2) the influence of timing of MUA from index procedure and of diabetes mellitus on final flexion achieved. We retrospectively evaluated patients who underwent manipulation following total knee arthroplasty at our institution between January 2016 to December 2018. For the purpose of analysis, we have divided the patients into two groups. Those who underwent manipulation within 12 weeks and later than 12 weeks. We have also compared the effect of MUA between diabetic and non-diabetic patients. All were operated with posterior stabilised (PS) prosthesis by a single senior arthroplasty surgeon. The final flexion achieved during their last clinical follow-up were recorded and compared with the pre MUA flexion. The incidence of MUA after TKA at our institute during this period is about 1.14 %. There was a significant statistical difference between the pre and post manipulation flexion, with p value <0.01. There was no significant statistical difference between those who were manipulated before 12 weeks and after 12 weeks in improving the Flexion of the operated knees. We have found that both the diabetic and non diabetic group had comparable flexion after the manipulation in our study. Manipulation after anaesthesia is a safe first intervention to improve post operative stiffness and gain additional range of motion following TKA in patients who develop stiffness. It can be done even after 12 weeks of surgery with reasonably good gain in range of motion.

The acute effect in performing common range of motion tests in healthy young adults: a prospective study

In the application of range of motion (ROM) tests there is little agreement on the number of repetitions to be measured and the number of preceding warm-up protocols. In stretch training a plateau in ROM gains can be seen after four to five repetitions. With increasing number of repetitions, the gain in ROM is reduced. This study examines the question of whether such an effect occurs in common ROM tests. Twenty-two healthy sport students (10 m/12 f.) with an average age of 25.3 ± 1.94 years (average height 174.1 ± 9.8 cm; weight 66.6 ± 11.3 kg and BMI 21.9 ± 2.0 kg/cm2) volunteered in this study. Each subject performed five ROM tests in a randomized order—measured either via a tape measure or a digital inclinometer: Tape measure was used to evaluate the Fingertip-to-Floor test (FtF) and the Lateral Inclination test (LI). Retroflexion of the trunk modified after Janda (RF), Thomas test (TT) and a Shoulder test modified after Janda (ST) were evaluated with a digital inclinometer. In order to show general acute effects within 20 repetitions we performed ANOVA/Friedman-test with multiple comparisons. A non-linear regression was then performed to identify a plateau formation. Significance level was set at 5%. In seven out of eight ROM tests (five tests in total with three tests measured both left and right sides) significant flexibility gains were observed (FtF: p < 0.001; LI-left/right: p < 0.001/0.001; RF: p = 0.009; ST-left/right: p < 0.001/p = 0.003; TT-left: p < 0.001). A non-linear regression with random effects was successfully applied on FtF, RF, LI-left/right, ST-left and TT-left and thus, indicate a gradual decline in the amount of gained ROM. An acute effect was observed in most ROM tests, which is characterized by a gradual decline of ROM gain. For those tests, we can state that the acute effect described in the stretching literature also applies to the performance of typical ROM tests. Since a non-linear behavior was shown, it is the decision of the practitioner to weigh up between measurement accuracy and expenditure. Researchers and practitioners should consider this when applying ROM assessments to healthy young adults.

Outcome of Cancellous screw vs K wire fixation for management of neglected lateral condyle fracture of humerus in children

Introduction: This study compares the outcome of two treatment modalities of fixing neglected lateral condyle fracture of humerus in children in terms of clinical and radiological outcomes.Materials and Methods: All patients presenting to our institution were screened for eligibility by clinico-radiological evaluation. Patients were randomized into two groups i.e. Cancellous screw (CS) fixation (group I) and K wire fixation (group II). Patients were treated by open reduction and internal fixation using CS or K wires of appropriate size accordingly. (21 patients in group I and 19 patients in group II). Bone graft was used in all patients to promote osteosynthesis. Average follow up of patients was 18 months (range 11-22 months). Final outcome was measured in terms of clinicoradiological union, immobilization time, loss of reduction, gain in range of motion and functional outcome measured by Liverpool elbow score.Result: 21 patients were in group I (CS) and 19 patients were in group II (K wire). Mean age for group I and II was 7.9 and 7.5 years. Mean delay in presentation for group I and II was 14.9 and 13.2 weeks. Mean gain in range of motion (at final follow up as compared preoperatively) for group I and II was 23.5 and 17.8. Mean duration of immobilization for group I and II was 11.3 and 9.6 weeks. Mean LES score was 8.7 and 8.3 in group I and II. Union was seen in 37 cases. Three patients had pre mature physeal closure. Pin tract infection was seen in 4 patients in group II which healed by dressing and antibiotics. No patient had ulnar nerve palsy. Conclusion: Both techniques provide stable fixation, union and good functional outcome and there was no difference in the LES, however less immobilization and improvement in range of motion was seen in Group I (CS)

Comparative Analysis of Neural Mobilization and Rhythmic Stabilization in Range of Motion and Hip Pain

Background: The hip is a structure of the human body in which occurs the junction of bone, articular, muscular and ligament structures. It is in the coxofemoral joint and has the function of supporting the whole-body weight, being one of the main joints responsible for ambulation. Objectives: To analyze the comparison of neural mobilization and rhythmic stabilization techniques in range of motion (ROM) and hip pain. Methods: The sample was composed by 20 patients, with mean age of 54±6 years, were divided into two groups of 10 patients: the patients who received the neural mobilization technique (G1) and the patients who received the rhythmic stabilization technique (G2). Results: The mean age of each group was 56±6 years (G1) and 52±6 years (G2). Among the evaluated, 12 (60%) were female, 14 (70%) were married, predominating the profession of housewife (35%). The great majority of the participants (95%) presented pain to the active movement, mainly to the movements of hip flexion and abduction. Regarding passive mobilization, 70% referred pains, predominating to the movements of hip external rotation and abduction. Conclusion: It was concluded that the neural mobilization and rhythmic stabilization techniques had satisfactory results in relation to ROM and pain in the hip region, but rhythmic stabilization had a greater gain of ROM and decrease of pain.

The acute time course of muscle and tendon tissue changes following one minute of static stretching

The purpose of this study was to investigate the time course of the changes of various muscle and tendon mechanical properties and the function responses of the plantar flexor muscles following 1 min of static stretching.Twenty-five healthy volunteers were assigned into a static stretching group or a control group. The static stretching group was tested with three different rest times (0 min,20 min,40 min) after 2x30s of stretching. Controls were tested before and after a control period (10 min) without stretching. Dorsiflexion range of motion (RoM), passive resistive torque (PRT), and maximum voluntary contraction (MVC) were measured with a dynamometer. Ultrasonography of the medial gastrocnemius (GM) muscle-tendon junction (MTJ) displacement allowed us to determine the length changes in the tendon and muscle, respectively, and hence to calculate their stiffness.Following the stretching, we observed a significant increase in RoM directly following the stretching, 20 min post-stretching, and 40 min post-stretching. However, no changes were found in other functional parameters (PRT, MVC) or structural parameters (muscle and tendon stiffness). No changes were detected in any variable in the control group.We conclude that a static stretching exercise of 2x30s increases the RoM for at least 40 min. However, this gain in RoM is not accompanied with more compliant muscle and/or tendon tissue, suggesting that 60s of static stretching might not be stimulus enough to induce changes in the muscle-tendon structure. Hence, we speculate that other factors, such as increased stretch tolerance, might be responsible for the changes in the RoM observed in the present study.

Unicondylar vs. total knee arthroplasty in medial osteoarthritis: a retrospective analysis of registry data and functional outcome.

It was the aim of our study to compare the functional outcome (WOMAC score, range of motion) achieved with unicondylar knee arthroplasty (UKA) and total knee arthroplasty (TKA). It was hypothesized that UKA and TKA would differ with regard to the WOMAC function scale (hypothesis 1) and the WOMAC total scale (hypothesis 2). It was assumed that the groups would differ with respect to changes in range of motion (ROM) over time (hypothesis 3). A retrospective comparative study was conducted to analyze data available from the federal state's Arthroplasty Registry (WOMAC score) and from clinical routine (ROM). Patients who underwent UKA or TKA between 2008 and 2015 were considered. ANOVAs for repeated measurements were applied, adjusted for age, to test hypotheses 1-3. The UKA group was comprised of 112 patients (age 65, BMI 29). The TKA group included 330 cases (age 69, BMI 29). Regarding hypothesis 1, the amount of improvement in WOMAC function was not influenced by the surgical group (no significant group*time interactions, p = 0.608). Similarly, for hypothesis 2, the amount of improvement in the WOMAC total score was not influenced by the surgical group (no significant group*time interactions, p = 0.392). Regarding hypothesis 3, we found no significant group*time interaction for the ROM data (p = 0.731). On the basis of our findings, it is concluded that whether knee osteoarthritis is treated with either medial UKA or TKA has no influence on the WOMAC total score or any of the WOMAC subscales. It has no effect on early or late ROM gain.

Reproducing the Native Posterior Tibial Slope in Cruciate-Retaining Total Knee Arthroplasty: Technique and Clinical Implications.

Total knee arthroplasty (TKA) profoundly influences knee biomechanics. Using an arbitrary (often 3° to 5°) posterior tibial slope (PTS) in all cases seldom will restore native slope. This study examined whether the native PTS could be reproduced in cruciate-retaining TKA and how this would influence clinical outcome. Radiographic and clinical outcomes of 215 consecutive TKAs using the PFC sigma cruciate-retaining implant were evaluated. The tibial bone cut was planned to be made parallel to the native anatomical slope in the sagittal plane. The PTS was measured with reference to the proximal tibial medullary canal (PTS-M) and the proximal tibial anterior cortex (PTS-C) on true lateral radiographs using a picture achieving and communication system. Knee range of motion (ROM), Knee Society Score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Short Form Health Survey (SF-12) were evaluated. Mean preoperative PTS-M was 6.9°±3.3°, and mean postoperative PTS-M was 7.0°±2.4°. Mean preoperative PTS-C was 12.2°±4.2°, and mean postoperative PTS-C was 12.6°±3.4°. Preoperative and postoperative PTS were not significantly different for both techniques (P>.05). An arbitrary 3° as an acceptable range for PTS-M was achieved in 144 knees (67%) (group 1), and 71 knees (33%) had a difference of more than 3° (group 2). Group 1 had a significantly larger gain in ROM (P=.04) as well as improved Knee Society, WOMAC, and SF-12 physical scores compared with group 2 (P<.01). The modified surgical technique reproduced the native tibial slope in cruciate-retaining TKA. Reproduction of the native PTS within 3° resulted in better clinical outcomes manifested by gain in ROM and knee functional outcome scores. [Orthopedics. 2020; 43(1):e21-e26.].

Efficacy of manipulation under anesthesia beyond three months following total knee arthroplasty

BackgroundStiffness after total knee arthroplasty (TKA) is often treated with manipulation under anesthesia (MUA) to improve range of motion (ROM). However, many authors recommend against MUA beyond 3 months after TKA. This study investigates the timing of MUA for stiffness after TKA, focusing on MUA performed at >12 weeks.MethodsIn total, 142 MUAs were retrospectively reviewed. “Early” MUAs were at <12 weeks after TKA; “Late” MUAs were >12 weeks. MUAs were further subdivided into 4 groups: 83 “Group I” cases at <12 weeks, 34 “Group II” between 12 and 26 weeks, 12 “Group III” between 26 and 52 weeks, and 13 “Group IV” at >52 weeks. Gains in ROM were compared between groups.ResultsGains in flexion and overall ROM were statistically equivalent in Early vs Late MUA when controlling for pre-MUA ROM. ROM gains between the early Group I and the later Groups II-IV were also statistically comparable. Overall ROM gain in Group I was 24.1°, 17.9° in Group II, 20.8° in Group III, and 11.1° in Group IV. There were no significant complications.ConclusionsEarly and late MUA resulted in statistically equivalent gains in ROM, regardless of timing after TKA. All groups showed an average improvement in ROM of ≥11°. MUA performed beyond 3 months, and even beyond 1 year, appears to be safe and may improve ROM and allow select patients to avoid revision surgery.

Hidrodilatación capsular versus cinesiterapia como tratamiento inicial en las capsulitis de dedos

IntroductionTo evaluate the effectiveness of early capsular ultrasound-guided hydrodilatation (HD) of the proximal interphalangeal or metacarpophalangeal joints in reducing joint stiffness and shortening kinesitherapy, as well as in improving hand functionality. Material and methodsWe performed a one-year quasi-experimental pretest-posttest study with a control group in patients with proximal interphalangeal or metacarpophalangeal capsulitis in complex regional pain syndrome stages 2 or 3. Inclusion criteria consisted of age over 18 years, visual analogue scale<4 points and the absence of prior treatment. The control group received only kinesitherapy and the experimental group received capsular HD before kinesitherapy. There were 10 patients per group. The main measures were range of motion, active grip, Spanish validated Michigan Hand Outcomes Questionnaire and the number of kinesitherapy sessions required. ResultsAt baseline, the range of motion of the proximal proximal interphalangeal joint was 20° worse in the experimental group (P=.01). There were no statistically significant differences in the other baseline characteristics. Immediate gain in range of motion after HD was 61.71% (P=.024). No significant improvements were observed in functionality except in active grip after 2 weeks of HD (P=.02) and one month later compared with the control group (P=.014). The number of kinesitherapy sessions required was 19.6±10.42 (95% CI) in the HD group and 29.4±8.11 (95% CI) in the control group (P>.05). ConclusionsCapsular HD could be considered as an initial treatment in finger joint stiffness because of the significant immediate improvement in range of motion. It is also an innovative technique in these joints with a short learning curve. The technique can be safely and effectively performed in a physiatry consulting room.

Clinical and functional evaluation of patients submitted to reverse arthroplasty with minimum one year of follow-up

ObjectiveTo assess the clinical and functional results of patients submitted to reverse arthroplasty with a minimum follow-up of one year. MethodsTwenty-two patients submitted to shoulder reverse arthroplasty by the Surgery and Shoulder Rehabilitation Group were retrospectively evaluated with pre and postoperative imaging analysis, analog pain scale, range of motion, and ASES functional score. ResultsOut of 19 (86.3%) patients with preoperative ASES classified as poor/bad, 11 (57.9%) progress to good/excellent after intervention, showing improvement of function, ranging from a mean preoperative ASES score of 22 (± 18.8) to a postoperative mean of 64.8 (± 27.7) (p=0.031). Regarding the pain, there was an improvement in analog pain scale, presenting a preoperative mean of 7.64 (1–10) and a postoperative mean of 2.09 (0–7; p<0.001). Regarding mobility, of 22 patients, 15 (68.2%) had preoperative pseudoparalysis and, of these, ten (66.7%) had an active anterior elevation greater than 90° after reverse arthroplasty. In turn, patients without pseudoparalysis had no significant gain in range of motion (p=0.002). The authors observed active anterior elevation gain, with a preoperative mean of 76° (0–160°) and a postoperative mean of 111° (0–160°; p=0.002). ConclusionDespite being a relatively new procedure in Brazil, reverse shoulder arthroplasty can be used effectively and safely in patients who were previously without treatment options such as rotator cuff arthropathy and revisions providing pain relief, improvement of function, and mobility of the upper limb.

Management of Neglected Lateral Condyle Fracture of Humerus: A Comparison between Two Modalities of Fixation.

Background:Implant for fixation of neglected fracture lateral condyle humerus remains an issue of controversy. This study compares the clinical and radiological outcome of fixation with Kirschner wire (K-wire) and with cancellous screw (CS) in neglected fracture lateral condyle humerus.Materials and Methods:42 patients of neglected lateral condyle humerus fracture, treated either by open reduction and internal fixation (ORIF) with K-wire or ORIF with CS were included in study. The comparisons were made in term of slab immobilization time, union time, improved range of motion (ROM), final achieved carrying angle, and functional outcome measured by Liverpool Elbow Score (LES).Results:There were 22 patients in Group I with mean age 7.8 years and 20 patients in Group II with mean age 7.3 years. Mean delay in presentation was 12.9 versus 15.6 weeks (P > 0.05). Mean followup was 26.9 versus 26.7 months. Mean duration of immobilization was 11.6 versus 9.4 weeks (P < 0.001). Improved carrying angle was 6.8° versus 9.7° (P < 0.05). Mean gain in ROM was 17.7° versus 27.5° (P < 0.05). Mean LES was 8.15 versus 8.18 (P > 0.05). Premature closure of physis was observed in two patients. Pin tract infection was seen in three of Group I (P > 0.05).Conclusion:There was no difference in LES, irrespective of implant used. Screw was better in terms of duration of slab, improvement in carrying angle and ROM.

Popeye sign: Frequency and functional impact.

There is currently no consensus on the choice between tenotomy and tenodesis of the long head of the biceps tendon in rotator cuff repair. The Popeye sign is often seen as a drawback of tenotomy. The main objective of the present study was to determine the frequency and clinical impact of the Popeye sign. The Popeye sign is rarely found clinically, and shows little functional impact following tenotomy. A single-center non-randomized prospective study was conducted between February and October 2015 in all patients undergoing rotator cuff surgery. Patients without surgery on the long head of the biceps tendon were excluded. The rate of Popeye sign was assessed 6 months postoperatively. Tenotomy patients with and without Popeye sign were compared in terms of pain on visual analog scale≤3, gain in range of motion, improvement in subjective shoulder value, discomfort or cramps and gain in Constant score. Seven of the 55 patients included (15.2%) showed postoperative Popeye sign. There were no differences between the groups with and without Popeye sign on any of the assessment criteria except for a significantly greater improvement in mean Constant range of motion score in the Popeye group: gain of 13.8 versus 3.8 points; p=0.01. The Popeye sign was relatively rarely observed. Functional impact in the present study was slight. Longhead of the biceps tenotomy is a justifiable treatment option in case of associated rotator cuff tear repair. IV, prospective non-randomized.
