Aims. To systematically review the outcomes and complications of cosmetic stature lengthening. Methods. PubMed and Embase were searched on 10 November 2019 by three reviewers independently, and all relevant studies in English published up to that date were considered based on predetermined inclusion/exclusion criteria. The search was done using “cosmetic lengthening” and “stature lengthening” as key terms. The Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement was used to screen the articles. Results. A total of 11 studies including 795 patients were included. The techniques used in the majority of the patients were classic 3- or 4-ring Ilizarov fixator (267 patients; 33.6%) and lengthening over nail (LON) (253 patients; 31.8%), while implantable lengthening nail (ILN) was used in the smallest number of patients (63 patients; 7.9%). Mean end lengthening achieved was 6.7 cm (SD 0.6; 1.5 to 13.0), and the mean follow-up duration was 4.9 years (SD 2.1; 41 days to 7 years). Overall, the mean number of problems, obstacles, and complications per patient was 0.78 (SD 0.5), 0.94 (SD 1.0), and 0.15 (SD 0.2), respectively. The most common problem and obstacle was ankle equinus deformity, while the most common complications were deformation of the regenerate after end of treatment and subtalar joint stiffness/deformity. Conclusion. Cosmetic stature lengthening provides favourable height gain, patient satisfaction, and functional outcomes, with low rate of major complications. Clear indications, contraindications, and guidelines for cosmetic stature lengthening are needed. Cite this article: Bone Joint Res 2020;9(7):341–350

Introduction. Cosmetic lengthening is currently growing, raising Ethical concerns. In cosmetic lengthening, the psychological benefit vs process and risks is not quantified in publications. We designed a prospective longitudinal study for evaluating quantitatively the psychological PROMs of patients with cosmetic lengthening and value its interest. Materials and Methods. Forty five cosmetic patients were operated on with the G-Nail with full weight-bearing, and sports: M/F 34/11, age 29.3±11.5 year-old, Gain 79 mm (range 86–187). All undertook preoperative preparation, psychological tests, post-operating training (lengthening period, twice daily) and a specific psychological program. No patient presented sequels. Questionnaires were provided before and 40.0 month after surgery (scale 0–10) with: Psychological suffering, Happiness in Life (HiL), Quality of Live (QoL), Self-Esteem, Self-Image, Self-Confidence, Professional, Family, Friends and Sexual Relations, Sexual Attraction. Average, SD of changes and T-Test (unequal variances) were computed. Results. Improvements were greater for self-Image (+54%, p 1.21×10. −12. ) raising from an initial value of 5.44 (+/− 1.62) to 8.40 +/− 1.20), Self-esteem, Self-confidence and HiL or over (p between 1.7×10. —7. and 1.8×10. −10. ), QoL (+22%, p 8.1×10. −5. ), Professional relationships (+20%, p 4.2×10. −5. ), Family relationships (+12%, p 0.003), Friendship (+11%, p 0.002), Sexual Attraction (+24%, p 1.0×10. −5. ), Sexual relationships (+19%, p 0.001) and psychological suffering due to the statue decreased by 53% (p 0.0002). Conclusions. Within the protocols used, patients improved strongly their Psychological Health, with +44% of their self-image, self-esteem and self-confidence. With a reliable technique and strong programs for supporting recovery both physically and psychologically, cosmetic surgery can benefit strongly to patients

The Ilizarov method for leg lengthening was used for cosmetic reasons in 54 patients with constitutional short stature. A mean lengthening of 7 cm with a low rate of complications produced an excellent or good outcome in all the patients, including improvement in psychological disturbances related to short stature. Those who undergo the procedure must be highly motivated, fully informed and understand the technique and possible complications. We suggest that the Ilizarov method for cosmetic limb lengthening is a technique without major complications. However, it requires careful follow-up, and the involvement of orthopaedic surgeons who are familiar with use of the circular frame and are experienced in limb lengthening and correction of deformity for pathological conditions

Introduction. The practice of limb lengthening using intramedullary nails has surged in popularity in recent years. Our study explores the relationship between femur lengthening and overall height gain in adults undergoing cosmetic limb lengthening with telescoping magnetic intramedullary lengthening nails (MILNs). Materials & Methods. Demographic information, pre- and postoperative radiographic data, and secondary outcomes, such as mechanical angles and sagittal alignment, were analyzed for 42 adult femurs MILNs (PRECICE 2, NuVasive, Inc.). Height was assessed with a digital stadiometer. Limb lengthening was defined as the amount of nail distraction seen on a calibrated weight bearing X-ray at consolidation. mLDFA, mMPTA, MAD, AMA, and femoral sagittal bow were evaluated as secondary outcomes. Results. Mean starting height was 163.5 cm (SD 10.4, range 137–179) Post -lengthening mean height increased to 171.1 cm (SD 10.1, range 146.7–185.3). Average height gain was 7.5 cm (SD 1.3 cm, range 5.1–9.5). Average femoral lengthening was 7.3 cm (SD 1.14, range 4.1–10.1). There were no statistically significant difference between height gain and femur lengthening. Secondary outcomes showed reductions in femoral sagittal bow and AMA. Conclusions. We conclude that measuring femur lengthening is a reliable and accurate method of measuring gained height in deformity-free patients undergoing limb lengthening. We further reason that straightening of both femoral and spinal sagittal bow counteracts potential lengthening loss over the anatomical axis, versus mechanical axis lengthening

Introduction. Distraction histogenesis is utilised for cosmetic reasons in patients with constitutional short stature, achondroplasias, or height dysphoria. One of the considerations of patients and surgeons alike, is the preservation of aesthetically acceptable body proportions after the lengthening i.e which segment of the lower limb to lengthen and by how much, in order to preserve the patient's proportions within -or as close as possible to- the normal range of human body proportions. Sound anthropometric data on the normal range of the human body proportions is currently lacking. The aim of this study is to calculate the normal range of the ratio between the lengths of the lower limb, upper limb, femur, tibia, stature and trunk. Methods. Data form standardized measurements of the lengths of the tibia, femur, arm, stature, lower limb, upper limb was obtained from a sample population of 6068 healthy men and women servicing in the US Army. The mean, median, range and standard deviation were calculated for the following ratios of lengths: whole lower limb/leg, Stature/leg, Whole lower limb/thigh, Stature/thigh, Siting height/whole lower limb, Stature/Whole lower limb, Arm Span/Stature, Whole upper limb/Whole lower limb. Results. The ratios show normal distribution. Results are presented separately for men and women for the total sample population and for subgroups based on ethnic origin (White, Black, Hispanic and Asian). Discussion. This study is one of the first to provide specific anthropometric data from a large sample population relevant to the evidence-based preoperative planning and patient counselling before cosmetic limb lengthening procedures

Study Design: A prospective study evaluated patients’, orthopaedists’ and not affected children of the same age ratings’ of preoperative and postoperative cosmesis in adolescents undergoing posterior spinal fusion for idiopathic scoliosis. The cosmetic result based on a questionnaire was compared to clinical and radiological parameters. There was no correlation between the SAQ and objective clinical and radiologic parameters at all, whereas clinical and radiological parameters showed good correlation. We recommend to standardly evaluate the cosmetic outcome as after scoliosis correction surgery. Introduction: Improving cosmesis is an important goal in scoliosis surgery. Patients’ satisfaction with the cosmetic outcome is essential in their evaluation of the surgical result. However, only few efforts were made in the past to investigate the cosmetic outcome. We performed a a prospective study evaluated patients’, orthopaedists’ and not affected children of the same age ratings’ of preoperative and postoperative cosmesis in adolescents undergoing posterior spinal fusion for idiopathic scoliosis. The cosmetic result based on a standardized questionnaire (SAQ, spinal appearance questionnaire) was compared to clinical and radiological parameters. Patient sample: Preoperative and postoperative photographs were taken from 32 patients (22 female, 10 male, average age 14.6 years) preoperatively and postoperatively in a standardized manner. Materials: The photographs were assessed by use of a modified SAQ. In addition radiological measurements were performed like the cobb angles of the main curves in the coronal and sagittal plane, plumb line deviation, shoulder inequality and pelvic obliquity. The clinical investigation included the measurements of shoulder asymmetry, pelvic obliquity, rip and lumbar hump, plumb line deviation, breast asymmetry and the postoperative evaluation of the scar. Results: The items general appearance, body shape, rib hump, and shoulder inequality of the SAQ improved most (p< 0.025). The patients judged the cosmetic result better than surgeons and healthy children (on average: 11 out 15 parameters of the SAQ improved) The surgeons came to the worst judgement (only 5 of 15 parameters improved). The interrater correlation of the surgeons was poor (ICC< 0.58). There was no correlation between the SAQ and objective clinical and radiologic parameters at all, whereas clinical and radiological parameters showed good correlation. Conclusion: As shown in our results objective clinical and radiological parameters do not correlate with the evaluation of the cosmetic result. Therefore we recommend to establish the evaluation of the cosmetic outcome as standard investigation after scoliosis correction surgery

1. The details of construction of the Stanmore cosmetic caliper using modern plastic materials have been described. 2. The considerable advantages of this light-weight caliper over the cumbersome traditional appliance are discussed

Background: To assess the cosmetic advantage of costotomy at the angle of the ribs on the convexity of a curve in the management of Adolescent Idiopathic scoliosis. Whilst modem segmental correction produces gratifying improvement in Cobb-angle and, to some extent rotation, rib asymmetry often remains as a concern for patients. Performing costotomy at the angle of the rib at the same time as corrective surgery can improve the cosmetic appearance significantly. It avoids any further scars or surgery, and is associated with minimal complications, the main one being pneumothorax and the requirement of a chest drain. Methods: Retrospective review of 50 patients. This has been a standard practice and this presentation reports on 50 patients treated in Preston with a variety of corrective devices; we have assessed results radiologically, with cosmetic acceptability by the patient and surface topographical analysis. Results: Significant improvement occurs at the time of costotomy as the ribs drop from their arched position after the coronal deformity has been improved. Conclusion: The addition of costotomy at the time of primary surgery for Adolescent Idiopathic Scoliosis leads to minimal complications. Significant improvement occurs at the time of costotomy as the ribs drop from their arched position after the coronal deformity has been improved. This is maintained in the post-operative period by moulding of the brace

It is suggested that the operation of partial costectomy is so beneficial psychologically to some young scoliotic patients that it is worth the very small physiological cost demonstrated here in patients who found their "hump" sufficiently embarrassing to curtail their normal social life.

Introduction: We conducted a prospective study on 29 patients comparing the medium-term outcome between intramedullary nail fixation and plate fixation in paediatric forearm fractures.

Materials and Methods: The criteria were patients who had a nail (10) or plate fixation (19) for a single or both bones forearm fracture between 2004 and 2006. All these patients were recalled following ethical approval for assessment of their grip strength using a hand dynamometer, forearm and elbow range of movements, scar assessment, POSNA outcome questionnaire and new radiographic views of the forearms.

Results: Mean age of 10.4 years for both groups (4–16), All fractures were caused by low velocity falls. Grip strength is reduced in 83% of patients, comparable in both groups. Elbow flexion is more reduced in the plating group but more reduction in extension in the nailing group. The reduction in forearm pronation (69% of patients) and supination (61%) were comparable in both groups. Using the ‘Manchester scar proforma’; the plating group scored worse with 14/21; nail 11/21. ‘POSNA outcome questionnaire’ score showed the nailing group had 90% excellent or good result and plating group 74%. The moderate and poor POSNA outcome (26% plate, 10% nail) were associated with pain, restricted rotation, bad scarring and difficulty lifting heavy objects. Nails were removed after bony healing but all plates were left in situ. Complete remodeling of forearm bones were seen in all radiographs in both groups. One case of non-iatrogenic ulnar nerve injury and two cases of wound infection were noted; all made full recovery.

Conclusion: The medium-term outcome at 2.5 years following either fixation method is generally comparable and good. The obvious differences were; a higher (better) POSNA score in the nailing group, larger scar formation in plating, elbow extension restriction in nailing and elbow flexion restriction in plating group. Factors that were comparable were grip strength, forearm rotation and radiographic remodeling and outcome.

Introduction and Objective. There remains much debate regarding the optimal method for surgical management of patients with long head of biceps pathology. The aim of this study was to compare the outcomes of tenotomy versus tenodesis. Materials and Methods. This systematic review and meta-analysis was registered on PROSPERO (ref: CRD42020198658). Electronic databases searched included EMBASE, Medline, PsycINFO, and Cochrane Library. Randomized controlled trials (RCTs) comparing tenotomy versus tenodesis were included. Risk of bias within studies was assessed using the Cochrane risk of bias v2.0 tool and the Jadad score. The primary outcome included patient reported functional outcome measures pooled using standardized mean difference (SMD) and a random effects model. Secondary outcome measures included visual analogue scale (VAS), rate of cosmetic deformity (Popeye sign), range of motion, operative time, and elbow flexion strength. Results. 751 patients from 10 RCTs demonstrated (369 tenotomy vs 382 tenodesis) were included in the meta-analysis. Pooled analysis of all PROMs data demonstrated comparable outcomes between tenotomy vs tenodesis (SMD 0.17 95% CI −0.02 to 0.36, p=0.09). Sensitivity analysis comparing RCTs involving patients with and without an intact rotator cuff did not change the primary outcome. Secondary outcomes including VAS, shoulder external rotation, and elbow flexion strength did not reveal any significant difference. Tenodesis resulted in a lower rate of Popeye deformity (OR 0.27 95% CI 0.16 to 0.45, p<0.00001). Conclusions. Aside from a lower rate of cosmetic deformity, tenodesis yielded no measurable significant benefit to tenotomy for addressing pathology in the long head of biceps. This finding was irrespective of the whether the rotator cuff was intact

Aims. The management of completely displaced fractures of the distal radius in children remains controversial. This study evaluates the outcomes of surgical and non-surgical management of ‘off-ended’ fractures in children with at least two years of potential growth remaining. Methods. A total of 34 boys and 22 girls aged 0 to ten years with a closed, completely displaced metaphyseal distal radial fracture presented between 1 November 2015 and 1 January 2020. After 2018, children aged ten or under were offered treatment in a straight plaster or manipulation under anaesthesia with Kirschner (K-)wire stabilization. Case notes and radiographs were reviewed to evaluate outcomes. In all, 16 underwent treatment in a straight cast and 40 had manipulation under anaesthesia, including 37 stabilized with K-wires. Results. Of the children treated in a straight cast, all were discharged with good range of mo (ROM). Five children were discharged at six to 12 weeks with no functional limitations at six-month follow-up. A total of 11 children were discharged between 12 and 50 weeks with a normal ROM and radiological evidence of remodelling. One child had a subsequent diaphyseal fracture proximal to the original injury four years after the initial fracture. Re-displacement with angulation greater than 10° occurred for 17 children who had manipulation under anaesthesia. Four had a visible cosmetic deformity at discharge and nine had restriction of movement, with four requiring physiotherapy. One child developed over- granulation at the pin site and one wire became buried, resulting in a difficult retrieval in clinic. No children had pin site infections. Conclusion. Nonoperative management of completely displaced distal radial fractures in appropriately selected cases results in excellent outcomes without exposing the child to the risks of surgery. This study suggests that nonoperative management of these injuries is a viable and potentially underused strategy. Cite this article: Bone Joint J 2021;103-B(5):902–907

Adolescent idiopathic scoliosis (AIS) is a complex 3D deformity of the spine. Its prevalence is between 2% and 3% in the general population, with almost 10% of patients requiring some form of treatment and up to 0.1% undergoing surgery. The cosmetic aspect of the deformity is the biggest concern to the patient and is often accompanied by psychosocial distress. In addition, severe curves can cause cardiopulmonary distress. With proven benefits from surgery, the aims of treatment are to improve the cosmetic and functional outcomes. Obtaining correction in the coronal plane is not the only important endpoint anymore. With better understanding of spinal biomechanics and the long-term effects of multiplanar imbalance, we now know that sagittal balance is equally, if not more, important. Better correction of deformities has also been facilitated by an improvement in the design of implants and a better understanding of metallurgy. Understanding the unique character of each deformity is important. In addition, using the most appropriate implant and applying all the principles of correction in a bespoke manner is important to achieve optimum correction. In this article, we review the current concepts in AIS surgery. Cite this article: Bone Joint J 2018;100-B:415–24

There remains much debate regarding the optimal method for surgical management of patients with long head of biceps pathology. The aim of this study was to compare the outcomes of tenotomy versus tenodesis. This systematic review and meta-analysis was registered on PROSPERO (ref: CRD42020198658). Electronic databases searched included EMBASE, Medline, PsycINFO, and Cochrane Library. Randomized controlled trials (RCTs) comparing tenotomy versus tenodesis were included. Risk of bias within studies was assessed using the Cochrane risk of bias v2.0 tool and the Jadad score. The primary outcome included patient reported functional outcome measures pooled using standardized mean difference (SMD) and a random effects model. Secondary outcome measures included pain (visual analogue scale VAS), rate of Popeye deformity, and operative time. 860 patients from 11 RCTs (426 tenotomy vs 434 tenodesis) were included in the meta-analysis. Pooled analysis of all PROMs data demonstrated comparable outcomes between tenotomy vs tenodesis (SMD 0.14, 95% CI −0.04 to 0.32; p=0.13). Sensitivity analysis comparing RCTs involving patients with and without an intact rotator cuff did not change the primary outcome. There was no significant difference for pain (VAS). Tenodesis resulted in a lower rate of Popeye deformity (OR 0.29, 95% CI 0.19 to 0.45, p < 0.00001). Tenotomy demonstrated a shorter operative time (MD 15.21, 95% CI 1.06 to 29.36, p < 0.00001). Aside from a lower rate of cosmetic deformity, tenodesis yielded no measurable significant benefit to tenotomy for addressing pathology in the long head of biceps. A large multi-centre clinical effectiveness randomised controlled trial is needed to provide clarity in this area

Few surgical techniques to reconstruct the abductor mechanism of the hip have been reported, with outcomes reported only from case reports and small case series from the centres that described the techniques. As in many of our revision THA patients the gluteus maximus was affected by previous repeat posterior approaches, we opted to reconstruct the abductor mechanism using a vastus lateralis to gluteus medius transfer. We report the results of such reconstructions in seven patients, mean age 66 (range, 53–77), five females, presenting with severe abductor deficiency (MRC grade 1–2). Five patients had previous revision THA, two with a proximal femoral replacement, one patient had a primary THA after a failed malunited trochanteric fracture, and one patient had a native hip with idiopathic fatty infiltration of glutei of >90%. All patients had instrumented gait analysis, and surface electromyography (EMG) of the glutei, TFL, and vastus muscles simultaneously before surgery and at each post-op follow-up. Postoperatively, patients were allowed to weight bear as tolerated and were requested to wear an abduction brace for the first six weeks after surgery to protect the transfer. All patients improved after surgery and reached an abductor power of 3 or more. All patients walked without support six months after surgery and were satisfied with the result. Abductor function continued to improve beyond one year of follow-up, and some patients reached an abductor power of 5. EMG demonstrated that the transferred vastus lateralis started firing synchronously with gluteus medius after three months post-surgery, suggesting adaptation to its new function. No knee extension weakness was recorded. One patient complained of lateral thigh numbness and was dissatisfied with the cosmetic look of her thigh after surgery. Our preliminary results are encouraging and comparable with those achieved by the originators of the technique

We undertook a randomised controlled trial to compare the outcomes of skin adhesive and staples for skin closure in total hip replacement. The primary outcome was the cosmetic appearance of the scar at three months using a surgeon-rated visual analogue scale. In all, 90 patients were randomised to skin closure using either skin adhesive (n = 45) or staples (n = 45). Data on demographics, surgical details, infection and oozing were collected during the in-patient stay. Further data on complications, patient satisfaction and evaluation of cosmesis were collected at three-month follow-up, and a photograph of the scar was taken. An orthopaedic and a plastic surgeon independently evaluated the cosmetic appearance of the scars from the photographs. No significant difference was found between groups in the cosmetic appearance of scars at three months (p = 0.172), the occurrence of complications (p = 0.3), or patient satisfaction (p = 0.42). Staples were quicker and easier to use than skin adhesive and also less expensive. Skin adhesive and surgical staples are both effective skin closure methods in total hip replacement

Introduction. Fully implantable distraction nails are frequently used for lengthening of the lower leg. What are the indications for humerus lengthening and which results can be expected?. Materials and Methods. The humerus as the best healing bone in the human body is suitable for lengthening with a nail as well but the indications are rare in comparison with the lower legs. Especially when driving a car or when working on a tablet length discrepancy of the arms of more than 4–5cm may cause severe hardening of the cervical muscles and induce chronical pain in the upper spine. Results. A distraction nail (FITBONE) was used in 5 cases for humerus lengthening. The nail was inserted in all cases from proximal. The mean age of the patients was 34 years. The mean lengthening amount was 58mm (55–100). In one case the system was exchanged to reach the desired length. There was no infection, no radial nerve irritation and no chronical shoulder pain. The system was removed in 4 cases in an average of 15 months the other nail will be removed soon as well. Conclusions. The preliminary results of our 5 cases demonstrate, that the FITBONE device is advantageous for lengthening the humerus, if the initial length is sufficient for implantation. In comparison with the use of external fixators the functional outcome, the comfort of treatment and the cosmetic result is amazing

Introduction. Fully implantable systems are used commonly only after maturity. What are indications to use fully implantable systems at the femur even in children?. Materials and Methods. Implantable lengthening nails (FITBONE) were used retrograde at the femur in minimal invasive technique to correct a limb length discrepancy of >6 cm. In 5 cases a relevant deformity was corrected in the same surgery. In all cases a final step of lengthening was planned at the femur and at the tibia with fully implantable devices at maturity. Results. 18 patients with the medium age of 10,3 years (8–14) were treated. In 17 cases the goal of lengthening was achieved without any complication. In one case of proximal femoral deficiency lengthening had to be stopped because of increasing tendency of knee joint luxation. Bone formation occurred circular around the nail in all cases. Full load bearing was possible in the average after 2,2 days/mm. No technical problems occur. In one case induced deformity in the lateral plane was observed which was corrected at the final step. At the end of treatment functional and cosmetical result was perfect in all cases. Conclusions. Fully implantable motorized distraction nails are a favorable option for lengthening and deformity correction of the femur even for children older than 10 years to correct limb length discrepancy of more than 6 cm. The treatment has a low pain level, is comfortable and nearly no scars are visible

Introduction. Deformations of forearm with different degree of expression and functional restrictions of upper limb in children with hereditary multiple exostosis are formed in almost 80% of the cases. The question of indications for the selection and conduct of surgical procedure remains controversial, existing treatment methods and post-operative recovery methods for children need to be improved. Materials and Methods. The long-term outcomes of surgical treatment of 112 patients diagnosed with “Hereditary Multiple Exostosis” (HME) aged from 2 till 17 years old were researched. Evaluation of surgical treatment results was carried out in accordance with complaints, functional condition of the forearm, radiographs (taking into account reference lines and angles). Depending on the variant of deformation, the following surgical operations were performed: resection of bone-cartilage exostoses (in 20.5%); correction of forearm deformation with external fixator (in 79.5). In 14 cases, for a more accurate correction of deformity a hexapod frame was used. Results. Differentiated approach provided “good” anatomical and functional results in 55.6%; “satisfactory” results in 40.2%; “unsatisfactory” results in 4.2%. Postoperative complications in the form of non-union, pseudoarthrosis, delayed consolidation or neurological disorders were in 6.2%. Conclusions. The choice of surgical treatment is determined by the variant and severity of deformation. This approach allows to improve cosmetic and functional condition of forearm and adjacent joints. The use of hexapod allows to increase accuracy of correction of physiological axis of forearm bones

Introduction. The Patient's Dream is not to stay in hospital even overnight, including in limb lengthening. We developed the ‘Hyper Fast Track Protocol’ (HFTP) in 2015 to fasten recovery and shorten hospital stay. Materials and Methods. The protocol included surgical stab incisions, use of weight bearing lengthening nails (G-Nail), intramedullary saw, a specific anaesthesia care (blood hypo-pressure, tranexamic acid, low hydration), absence of early anticoagulants, systematic vascular US controls, but early motion (hip and knee Ext/Fle, leg raise, horizontal ‘scissors’), walking, stairs, bike, clicking (maneuvers to lengthen), early discharge, along with other patient's parameters. Timing and exercises reps were registered. Protocols improved over time. Means ± SD are computed. Results. Forms were analysed in 112 patients (unilateral 7, dwarfism 2, cosmetic 103). Besides patients operated in the afternoon (18), physio sessions initiated (h:mm) in average 0:46 ± 0:19 after awakening in operative room, for a duration of 2:15 ± 0:46. No DVT was noted on US nor clinically. In 2016, hospitalisation averaged 2.88 nights, decreasing to 2.07 in 2017, then to 1.07 from 2020. In late 2020 and in 2021, we had several patients in Daycare only, even in bilateral lengthening. In late 2021, we could discharge a patient after walking, full motion and exercises 3.5 hours after awakening from bilateral surgery. Conclusions. With continuous result monitoring and constant improvement of Care, walking, stairs, clicks and biking are fully feasible within 3h of surgery awakening, with discharge on the same day, using specific protocols
