RESUMO
PURPOSE: Skin closure disorders in ankle surgery are a recurrent problem not only in traumatology but also in elective surgery. The aim of the study was to describe the anatomical basis of the fasciocutaneous vascularization of the lateral malleolus region to develop a posterior cover flap for the region. METHODS: We dissected ten fresh frozen specimens after arterial injection of an Indian ink preparation and individualized the perforating arteries. Their positions and diameters were collated. Then, the surgical technique was clinically applied for two different cases by transferring the fasciocutaneous flap posterior to the lateral malleolus to cover a loss of skin substance. RESULTS: There were in average 5 fibular perforators over the last 100 mm of the fibula. The average diameter of the first two perforating arteries was 0.6 ± 0.12 mm and 0.9 ± 0.25 mm, respectively, and the consistency of the latter makes it possible to produce a skin flap with anterior translation. This is an axial flap. Two patients were operated on using this technique. There was no necrosis of the posterior fibular flap and healing was achieved by the third post-operative week. CONCLUSION: This study showed the presence of fibular perforating arteries with a high reproducibility of their dissection. This anatomical description served as the basis for the description of a new distal fibular perforating flap.

BACKGROUND: Few data are available about the impact of operative time on outcome of rotator cuff repair. AIM: The aim of this study was to evaluate the impact of operative time on clinical outcome and tendon healing after arthroscopic rotator cuff repair. METHODS: Patients operated on for distal supraspinatus tear in our institution between 2012 and 2018 were included retrospectively. Operative time, from skin incision until skin closure, was extracted from medical files. For statistical analysis, operative time was treated as a quantitative variable. Endpoints were clinical outcome (Constant score, range of motion), tendon healing (on CT or MRI) and complications at 1 year. The significance threshold was set at p = 0.05. RESULTS: A total of 219 Patients, with a mean age of 54.6 years (range 40-70 years), were included. Mean operative time 44.9 min (range 14-140 min). Significant correlations (p < 0.05) were found for Constant score and external rotation at 1 year: increasing operative time by 1 min led to a decrease in Constant score of 0.115 points, or 6.9 points for a 60-min increase (p = 0.0167) and a decrease in external rotation of 0.134°, or 8.04° for a 60-min increase (p = 0.0214). No significant correlations were found for anterior elevation at 1 year (p = 0.2577), tendon healing at 1 year (p = 0.295) or onset of complications during follow-up (p = 0.193). DISCUSSION: The minimal clinically important difference in Constant score in patients undergoing rotator cuff surgery is between 6 and 10 points. An increase of more than 60 min in operative time significantly impacted clinical outcome of arthroscopic distal supraspinatus repair, but not tendon healing. LEVEL OF EVIDENCE: Level III: Retrospective Cohort Design. Therapeutic Study.

BACKGROUND: A pre-existing mood and anxiety disorder (MAD) is often present in patients with rotator cuff pathology, but its presumed negative effect on the outcomes has not been demonstrated. AIM OF STUDY AND HYPOTHESIS: The primary objective of this study was to evaluate how a history of MAD affects the clinical outcomes 1 year after arthroscopic rotator cuff repair (RCR). The secondary objectives were to evaluate how a history of MAD affects tendon healing, analgesic consumption and the occurrence of complications. MATERIALS AND METHODS: The study population consisted of 219 patients (mean age 54.5±6.6 years) who underwent arthroscopic repair for a distal supraspinatus tendon tear, with 17% (38/219) presenting an history of MAD (depression, unspecified mood disorder, anxiety, and bipolar disorder). Using univariate and multivariate analyses, the joint range of motion, Constant score, analgesic consumption, occurrence of complications during the first postoperative year and tendon healing at 1 year (MRI or CT arthrography) were compared between the two groups (with or without MAD). RESULTS: The Constant score was lower preoperatively in patients with history of MAD (-4 points, p=.04) but there were no significant differences between the two groups at the various postoperative follow-up time points (p>.05). No significant difference was found between the two groups of patients in their analgesic consumption at the various postoperative time points (p>.05), tendon healing at 1 year (p=.17) or the occurrence of postoperative complications (p=.59). DISCUSSION/CONCLUSION: Pre-existing MAD had no effect on the clinical outcomes after arthroscopic RCR at 1 year and no effect on tendon healing, analgesic consumption or the occurrence of complications in our study population. LEVEL OF EVIDENCE: III; retrospective case-control study.

Double-layered patella (DLP) is an osseous disorder associated with multiple epiphyseal dysplasia (MED). A thorough investigation should be conducted prior to surgery to assess the role of each layer and their vascularization in order to establish the best surgical strategy. We present the case of a woman in her late 50s with MED, bilateral DLP, and secondary osteoarthritis treated by a left total knee arthroplasty (TKA). To plan the surgical procedure, bilateral knee magnetic resonance imaging was obtained to study the anatomy of the two bony layers and their relationship to the extensor mechanism. In addition, a computed tomography angiography was performed to study the origins of arterial blood supply to the patella layers to avoid postoperative bone necrosis. During a standard TKA procedure, after adjusting the thickness of the posterior layer, we fused both layers using outside-in headless compressive screws. Clinical outcome was satisfactory with no anterior knee pain and radiographs showed signs of bone fusion between layers at last follow-up. No case report was found in the literature in which a full preoperative investigation was made to establish the best surgical management of a DLP during TKA. In such a case, the surgeon should be aware of the distinct roles of both layers (whether in the case of trauma or scheduled surgery) and make sure that the reconstruction plan will provide a favorable outcome.

INTRODUCTION: In situ contouring is one of the surgical techniques used for scoliosis reduction. The initial correction could change over time, with deterioration of the sagittal balance. The purpose of this study was to analyze the loss of correction after degenerative lumbar scoliosis surgery using in situ contouring. MATERIALS AND METHODS: Full spine radiographs of 73 patients (mean age 63.3 years, mean follow-up 27 months) were analyzed before surgery, after surgery, and at the final follow-up. The following radiographic parameters were measured: C2-C7 lordosis, T4-T12 kyphosis, L1-S1 lordosis, pelvic tilt, pelvic incidence, sacral slope, SVA C7, SVA C2, Cobb angle. Bayesian inference was used to compare the changes in these parameters. A probability>0.95 was considered as a significant change. RESULTS: After surgery, lumbar lordosis increased from -28.4° to -37.8° (probability 0.999), then decreased to -32.1° at the final follow-up (probability 0.953). Thoracic kyphosis increased from 29.6° to 37.4° after surgery (probability 1.00) and continued to increase to 41.6° at the final follow-up (probability 0.999). SVA C7 increased from 38.5mm to 62.3mm (probability 0.999) and pelvic tilt from 19.4° to 25.1° (probability 1.00) during the follow-up period. Ten patients had to be reoperated because of a surgical site infection. Infection (14%) was associated with an increase of SVA C7 (probability 0.989) and thoracic kyphosis (probability 0.987). Nonunion (16%) was associated with a decrease in lumbar lordosis (probability 0.756). CONCLUSION: Correction of degenerative lumbar scoliosis by in situ contouring resulted in sagittal balance correction; however, some of this correction was lost during the follow-up period. The main risk factors were deep wound infection and nonunion. LEVEL OF EVIDENCE: IV, Retrospective study.

BACKGROUND: One of the treatment options for comminuted radial head fractures is radial head arthroplasty (RHA), especially when the elbow is also dislocated. While the clinical outcomes of RHA have been well documented, the incidence of post-traumatic osteoarthritis after RHA and its risk factors are not well known. OBJECTIVE: To determine the incidence of post-traumatic elbow osteoarthritis (humeroulnar and humeroradial joints) after RHA and identify its risk factors. METHODS: All patients who underwent RHA at our hospital between 2008 and 2016 were included retrospectively. The inclusion criteria were primary RHA, recent radial head fracture (isolated or associated with elbow dislocation), minimum 1 year of follow-up, clinical and radiographic examination at final assessment. The exclusion criteria were pre-existing elbow osteoarthritis, RHA revision, multiple fractures of the ipsilateral upper limb or polytrauma. The final assessment consisted of a clinical examination [joint range of motion (ROM) and Mayo Elbow Performance Score (MEPS)] and standard radiographs. The correlation between the incidence and severity of osteoarthritis and various risk factors was determined. RESULTS: Seventy-three patients were included in the analysis with a mean age of 56 years (21-85). The injuries consisted of 41 terrible triad, 15 isolated radial head fractures, 11 Monteggia fractures and 6 transolecranon fracture-dislocations. The mean follow-up was 3.4 years (1-10.9). At the final assessment, osteoarthritis was visible in the humeroulnar compartment in 56% of cases and in the humeroradial compartment in 72% of cases. There was a statistical correlation between the presence of humeroulnar osteoarthritis at the final assessment and ROM in flexion-extension (p=0.003), MEPS (p<0.001), duration of immobilization (p=0.03) and presence of posterior subluxation on immediate postoperative radiographs (p=0.012). The correlation between humeroradial osteoarthritis at the final assessment and ROM in flexion-extension (p=0.0054), RHA implant position (p<0.01), and unipolar configuration (p=0.027) was statistically significant. CONCLUSION: In our study, elbow osteoarthritis incidence after RHA was 56% in the humeroulnar joint and 72% in the humeroradial joint. RHA implant placement, posterior subluxation immediately postoperative and the duration of immobilization were significantly corelated with osteoarthritis. LEVEL OF EVIDENCE: IV; case series without control group.

BACKGROUND: Trunnionosis of large diameter (LDH) metal-on-metal total hip arthroplasty (THA) was linked to high systemic chromium (Cr) and cobalt (Co) ion levels and local adverse reactions to metal debris (ARMD). The safety of CoC LDH THA is not yet available at mid-term. Measuring whole blood Ti level of ceramic on ceramic (CoC) LDH THA with a titanium (Ti) stem is an indirect way to assess the performance of its head-neck taper modular junction. Therefore, we wanted to determine: (1) if the whole blood Ti ion levels in patients with LDH CoC THA after a minimum of 5 years of implantation is within the expected values for similar well performing Ti THA, (2) if Ti level scientifically increases over time, which would suggest the presence of a progressive modular head/neck junction wear process, (3) if clinical or radiographical manifestations of implant dysfunction are present? HYPOTHESIS: Ti blood levels of LDH CoC THA will indirectly reflect the expected levels due to passive corrosion of the implants and will be stable over time. PATIENTS AND METHODS: We report the whole blood Ti, Cr, and Co levels at 5years minimum for 57 patients with unilateral primary LDH CoC THA with head sizes ranging from 36 to 48mm using Ti stem and acetabular component. To compare Ti ion levels modification over time, in 25 patients were a previous measurement (1-3years) was available, we compared it to their last follow-up results (>5 years). Mean Ti level in well performing Ti THAs is recognized to be around 2.0 ug/L. Although, there are no universally accepted Ti levels associated with problematic implant, we used safety threshold of 10 ug/L. Clinical and radiological outcomes were recorded at last follow-up. RESULTS: At 79 months mean follow-up, all mean Ti levels were 1.9µg/L (min 1.2, max 4.4) and all subject had values below the safety threshold of 10ug/L. In the subgroup of 25 cases with a previous measurement, there was a decrease in mean Ti levels between 20 months and 78 months follow-up (2.2µg/L (1.6-3.9) versus 2.0µg/L (1.4-2.8), p=0.007). No statistically significant relation was observed between Ti level at last FU and bearing diameter (rho=0.046, p=0.0734) or the presence or absence of a Ti adaptor sleeve (p=0.454): 1.94ug/L (min 1.20, max 2.80) versus 1.90ug/L (min 1.20, max 4.40). At last follow up, no patients presented osteolysis signs on radiographs, clinical signs of ARMD or were reoperated. Most patients had excellent clinical with 98% of them reporting minor (29%) or no functional limitation (69%) and 44% perceive their THA as a natural hip joint. However, 3/57patients (5%) temporarily experienced hip squeaking and 18/57 (31%) reported clicking sound. CONCLUSION: With the tested LDH CoC THA, Ti levels were low and related the uneventful and unavoidable passive corrosion of implant surfaces. Mid-term measurement of Ti in subjects with LDH CoC did not reveal any indirect signs of trunnionosis, which should already be observable by this time. LEVEL OF EVIDENCE: IV, retrospective study.

BACKGROUND: The current management of displaced capitellum fractures is traditionally surgical. Most authors perform open reduction and internal fixation. The working hypothesis was that closed reduction and internal fixation of capitellum fractures is achievable by arthroscopy. METHODS: We carried out a cadaveric study on six fresh frozen elbows. We performed two Bryan and Morrey type I fractures of the capitellum, three type II and one type IV using a 15 mm osteotome. Fracture reduction was performed under arthroscopy using a probe hook and an aiming femoral instrument set. Fixation with a lag screw was performed under arthroscopy and radioscopic control. We reviewed, two patients who had been operated on for a type I and type II capitellum fracture and osteosynthesized under arthroscopy with a 7.5 years follow-up. RESULTS: In our cadaveric study, we obtained anatomical reduction and stable osteosynthesis in four cases. We had two failures (2 type II fractures) due to a fracture of the fragment during screwing. In our clinical study, range of motion was very satisfactory with only a 5° extension deficit. The x-rays did not reveal any signs of osteoarthritis or periarticular ossification. One patient had minimal signs of osteonecrosis. CONCLUSIONS: Arthroscopic osteosynthesis of capitellum fractures is feasible and reproducible. We recommend cannulated lag screws for Bryan and Morrey type I and IV fractures and adjustable lock pins for type II fractures. We have shown that this technique gives good results on two patients with a 7.5-year follow-up. LEVEL OF EVIDENCE: IV.

INTRODUCTION: Medial valgus-producing tibial osteotomy (MVTO) is classically used to treat early medial femorotibial osteoarthritis. Long-term results depend on the mechanical femorotibial angle (HKA) obtained at the end of the procedure. A correction goal between 3 and 6° valgus is commonly accepted. Several planning methods are described to achieve this goal, but none is superior to the other. OBJECTIVE: The main objective was to compare the accuracy of the correction obtained using either the Hernigou table (HT) or a so-called conventional method (CM) for which 1° of correction corresponds to 1° of osteotomy opening. The secondary objective was to analyze the variations observed in the sagittal plane on the tibial slope and on the patellar height. The working hypothesis was that the HT allowed a more accurate correction and that the tibial slope and patellar height were modified in both groups. MATERIAL AND METHOD: In this monocentric and retrospective study, two senior surgeons operated on 39 knees (18 in the CM group, 21 in the HT group) between January 1, 2009 and December 31, 2014. The operator was unique for each group and expert in the technique used. The correction objective chosen for each patient, and written in the operative report, was considered as the one to be achieved. The surgical correction was the difference between the pre-operative and immediate post-operative data (< 5 J) for the mechanical tibial angle (MTA) and the hip-knee-ankle (HKA) angle. Surgical accuracy, where a value close to 0 is optimal, was the absolute value of the difference between the surgical correction performed and the goal set by the surgeon. RESULTS: The median surgical accuracy on the MTA was 3.5° [0.2-7.4] versus 1.4° [0-4.1] in the CM and HT groups, respectively (p = 0.006). In multivariate analysis, with the same objective, the CM had a significantly lower accuracy of 1.9° ± 0.8 (p = 0.02). For HKA, the median accuracy was 3.1° [0.3-7.3] versus 0.8° [0-5] in the CM and HT groups, respectively (p = 0.006). Five (5/18, 28%) and 16 (16/21, 76%) knees were within 3° of the target in the CM and HT groups, respectively (p = 0.004). The median tibial slope increased in both groups. This increase was significantly greater in the CM group compared with the HT group, with 5.5° [- 0.3-13] versus 0.5 [- 5.2-5.6], respectively (p < 0.001). The median Caton-Deschamps index decreased (patella lowered) in both groups after surgery, by - 0.21 [- 1.03; - 0.05] and - 0.14 [- 0.4-0.16], but without significant difference (p = 0.19). In univariate analysis, changes in tibial slope and patellar height were not significantly related to frontal surgical correction performed according to ΔMTA (R2 = 0.07; p = 0.055) and (R2 = - 0.02; p = 0.54) respectively. DISCUSSION: The correction set by the surgeons was achieved with greater accuracy and more frequently in the HT group, confirming the working hypothesis. The HT is therefore recommended as a simple way of achieving the set objective; the tibial slope and patellar height were modified unaffected by the frontal correction performed.

INTRODUCTION: Working hypothesis: The distal humeral bone density influences supracondylar fracture threshold. The aim of this study was first to develop a reproducible model of intra-articular distal humeral fractures and second to establish a relationship between bone mineral density (BMD) and the fracture threshold of the humerus. MATERIALS AND METHODS: An original model of the fracture was developed using ten sawbones. After obtaining a reproducible and clinically relevant fracture model, we tested 21 cadaveric distal humeri for which the BMD was known with a stainless-steel custom-made proximal ulna jig. Fractures were created using a servo hydraulic-testing machine in axial compression to simulate a fall onto an outstretched hand. Fracture lines, load to failure, and rigidity of the bone were recorded based on the stress-strain curves. RESULTS: The fracture generation was reliable, reproducible, and clinically relevant (type B2). A significant correlation between the BMD and the fracture threshold was found. Mean threshold was 901.86 N/m2. Mean distal humerus BMD was 0.9097 g/cm2 (r = 0.7321). CONCLUSIONS: We developed a reproducible articular fracture of the distal humerus model and found a correlation between the fracture threshold and bone mineral density.

BACKGROUND: Metal ion blood concentrations evaluation can be useful in monitoring wear and corrosion of orthopedic implants. Elevated metal ion level may help detecting defective hip arthroplasty implants and serve as an indicator for revision surgery. Our objective was to evaluate the reproducibility of titanium metal ion level measurements by two different laboratories. METHODS: Seventy-one whole blood samples were collected from 64 patients with unilateral ceramic-on-ceramic hip arthroplasty. For each patient, two whole blood samples were collected and analyzed in two different laboratories. RESULTS: For each case, laboratory 1 had significantly higher values than laboratory 2. There was a clinically significant absolute difference between the two laboratories, above the predetermined threshold, for 90% of samples. A mean variation ratio of 410% between the two laboratories was found. CONCLUSION: Not all laboratories use the same techniques and calibrations to perform these measurements. Therefore, their results should be interpreted with caution and clinical decision should rely on metal ion trends provided by the same laboratory.
RESUMO
INTRODUCTION: Results of iterative ACL reconstructions are lower than after primary reconstructions. Our aim was to report the results of a retrospective series of revision using pedicled quadruple hamstring autograft. The hypothesis was that the results were satisfactory and comparable to the literature. METHODS: The study period was from January 2012 to December 2014. Fourteen patients (average age 26) were included. A fascia lata graft was used 12 times for primary reconstruction. Trauma was the cause of failure 12 times. The time interval between primary reconstruction and revision was 6.2 years. Preoperative scores used were LYSHOLM, TEGNER and IKDC. Sagittal stability was measured using the KT-1000 device. X-rays and MRI were performed to confirm the diagnosis, look for preoperative osteoarthritis and evaluate the position of the bony tunnels (Bernard and Hertel). Bone tunnels were in a proper position 14 times. RESULTS: At 45-month follow-up, improvement of objective IKDC score was significant (85.7% A/B, p < 0.0002) as well as subjective IKDC score (85.5, p < 0.0004). A significant improvement was established for the LYSHOLM score (91.8, p = 0.001) using the Wilcoxon test. The average LYSHOLM score was 92% (p > 0.5), and the average TEGNER score was 5.5 (p = 0.003). The Lachman test found a hard stop in all patients. The pivot shift test was negative for 78.5% of the cases. The laxity measurement found 12 cases with less than 3 mm. One persistent distal hypoesthesia at 2-year follow-up was observed. CONCLUSION: The hypothesis was confirmed. This series differs by the cause of failure, which was essentially traumatic, and the initial predominance of a fascia lata graft. These results remain to be confirmed. LEVEL OF EVIDENCE: Retrospective case series, level IV.

INTRODUCTION: Meniscal cysts are rare in Stoller grade II horizontal lesions. Several techniques are described in the literature for their management, without any real gold standard. The objective of this work was to report a series of meniscal sutures associated with cyst resection by arthrotomy. The hypothesis was that the results were satisfactory and comparable with the data in the literature regardless of the technique reported without morbidity added by arthrotomy. MATERIALS AND METHODS: This was a monocentric retrospective study on 13 patients, aged 33 on average with a grade II meniscus lesion associated with a cyst (9 lateral and 4 medial menisci). Pre-operative data available was the VAS (5.7/10) and the Lysholm score (61/100). Primary endpoints were as follows: pain (visual analogue scale), global satisfaction, Lysholm functional score, and return to sports and professional activities at a minimum of two years. Secondary endpoints were complications, possible recurrence, and/or surgical revision. Recurrences, complications, and surgical recovery were gathered. RESULTS: Patients were evaluated with an average follow-up of 32 months. All patients were satisfied or very satisfied. The VAS significantly improved (0.2/10, p < 0.05) as well as the Lysholm score (97/100, p < 0.05). All patients returned to their professional activity: 11 within two months, one within six weeks, and one in the first post-operative week (this patient being a student). Only one patient did not resume pre-operative sport level due to a femoropatellar syndrome, not linked to the meniscal surgery performed. However, only 11 patients resumed their previous sport level (84.6%). No recurrence or surgical revision occurred. DISCUSSION: The results are good and similar to the literature, confirming the working hypothesis. These results are equivalent to partial meniscectomies and arthroscopic sutures associated with a procedure on the cyst by arthroscopy or arthrotomy. The literature is in favour of a procedure on the cyst. CONCLUSION: The results confirm the effectiveness of a direct approach suture of non-transfixing meniscal lesions associated with a cyst resection with a good functional recovery, without additional morbidity. The hypothesis was confirmed.

Proximal femur fractures have significant functional repercussions in both older adults (sometimes life-threatening) and younger adults (socioeconomic). This study will review the early mechanical complications (EMC) associated with the fixation of femoral neck (FNF) and trochanteric (TF) fractures. What is the nature of these complications? They consist of incorrect fracture fixation, secondary displacement and/or fixation failure (FNF: 3-10%; TF: 5-7%), and more rarely, secondary fractures distal to the implant. What are the risk factors and how can they be controlled? They are related to the patient (osteoporosis), to the type of fracture (FNF: posterior comminution, magnitude of displacement, vertical fracture line, fracture of calcar/TF: comminution of calcar, lesser trochanter fracture, metaphyseal comminution, lateral cortex fracture, greater trochanter comminution), to the chosen treatment (FNF: triple screw fixation or screw-plate are preferable/TF: all implants suitable for simple fractures, cervicomedullary implants for complex fractures), and to the surgical technique (quality of reduction, implant positioning). How should they be treated? Early revision of internal fixation can be difficult and increases the infection risk. Inter- or subtrochanteric valgus osteotomy leads to satisfactory results but is difficult to carry out. Secondary arthroplasty, which is the preferred option in older adults, leads to good outcomes but is technically more difficult, and has a higher complication rate in EMC of trochanteric fractures. LEVEL OF EVIDENCE: V.

PURPOSE: The objective was to evaluate clinical and radiological outcomes, survival rate and complications of primary contemporary rotating hinged total knee arthroplasty (CRH-TKA). METHODS: Through a national multicenter retrospective study (14 centers), 112 primary CRH-TKA performed between 2006 and 2011 were included. Indications were: severe frontal plane deformity (55%), inflammatory, constitutional, congenital or post-trauma arthritis (26%), ligament laxity (10%), primary osteoarthritis (9%). Population was elderly (68 ± 13), sedentary (37.5% with a Devane score ≥ 3) and with important comorbidities (87% with ASA score ≥ 2). A clinical (KSS, Oxford scores) and radiological evaluation (implant loosening), as well as survival and reoperation rates assessment, were performed. RESULTS: At last follow-up (7 ± 3 years), KSS and Oxford scores were 64 ± 43 and 33 ± 10 each with a significant improvement of both scores overtime (respectively, p = 0.047 and p < 0.001). Twenty-eight complications (25%) were reported: 12 infections, 6 stiffness, 5 aseptic loosening and 5 patellofemoral instabilities. All in all, 91% (n = 102) of implants were still sealed and in place, 6% (n = 7) required revision and 3% (n = 3) were loose but could not undergo revision due to weak general health status. Mortality rate (18%, n = 20), linked to comorbidities, was high. CONCLUSION: Clinical outcomes and survival of primary CRH-TKA are acceptable given the difficult and complex clinical situations it faced, but with high infection rate. In primary surgery, for patients with severe deformity, bone loss or ligament laxity, the use of CRH-TKA can be recommended. The choice of these implants must remain cautious and limited to situations not allowing the use of less constrained implants. LEVEL OF EVIDENCE: Retrospective therapeutic and cohort study, Level III; retrospective case series, Level IV.

BACKGROUND: Assessing patients' functional outcomes following total knee arthroplasty (TKA) with traditional scoring systems is limited by their ceiling effects. Patient's Joint Perception (PJP) question of the reconstructed joint is also of significant interest. Forgotten Joint Score (FJS) was created as a more discriminating option. The actual score constituting a "forgotten joint" has not yet been defined. The primary objective of this study is to compare the PJP and the FJS in TKA patients to determine the FJS score that corresponds to the patient's perception of a natural joint. METHODS: One hundred TKAs were assessed at a mean of 40.6 months of follow-up using the PJP question, FJS, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Correlation between the 3 scores and their ceiling effects were analyzed. RESULTS: With PJP question, 39% of the patients perceived a natural joint (FJS: 92.9; 95% confidence interval [CI], 89.4-96.4), 12% an artificial joint with no restriction (FJS: 79.5; 95% CI, 65.7-93.3), 36% an artificial joint with minor restrictions (FJS: 70.0; 95% CI, 63.2-76.9), and 13% had major restrictions (FJS: 47.3; 95% CI. 32.8-61.7). PJP has a high correlation with FJS and WOMAC (Spearman's rho, -0.705 and -0.680, respectively). FJS and WOMAC had a significant ceiling effect with both reaching the best possible score in >15%. CONCLUSION: Patients perceiving their TKA as a natural knee based on PJP have a FJS ≥89. PJP has a good correlation with FJS and may be a shorter, simple, and acceptable alternative.

BACKGROUND: During the surgical treatment of terrible triad elbow injury (TTEI), the usefulness of re-attaching the anterior joint capsule when the coronoid tip is fractured remains unclear. The primary objective of this study was to assess potential benefits during surgery for TTEI of re-attaching the joint capsule when the coronoid tip is fractured. HYPOTHESIS: Re-attaching the anterior joint capsule in TTEI with a fractured coronoid tip improves clinical and radiological outcomes and decreases the complication and revision rates. MATERIALS AND METHODS: This single-centre retrospective study included patients who underwent surgery at the acute phase of TTEI with a fractured coronoid tip. In all patients, a physical examination and elbow radiographs were performed at least 1year after surgery. A statistical analysis was done to compare the groups with vs. without re-attachment of the anterior capsule and coronoid tip. RESULTS: The study included 30 patients, 16 females and 14 males, with a mean age of 51years (range: 21-84years). Among them, 11 did and 19 did not undergo re-attachment. The two groups were comparable regarding demographic features and follow-up duration. No significant differences were found at last follow-up for flexion-extension motion arc (p=0.75), pronation-supination motion arc (p=0.3051), or the Mayo Elbow Performance Score (p=0.19). Radiographic evidence of humero-radial osteoarthritis was significantly more common in the absence of re-attachment (p=0.04), whereas no differences were evidenced regarding humero-ulnar osteoarthritis (p=0.73), the occurrence of subluxation or dislocation (p=0.43), or loosening of the radial head implant (p=0.47). The complication and revision rates were similar in the two groups. CONCLUSION: In our experience, re-attaching the anterior capsule during the surgical treatment of TTEI with a coronoid tip fracture did not improve the clinical or radiographic outcomes after a mean follow-up of 54months. LEVEL OF EVIDENCE: IV, retrospective study.

PURPOSE: Few studies describe the specific results of anterior cruciate ligament reconstruction with pedicled hamstring graft (HG). Our goal was to report the isokinetic, clinical, and functional outcomes over the post-operative year following pedicled hamstring ligamentoplasty. METHODS: Twenty-four patients with ACL rupture (mean age 27.4 years) were included prospectively. The technique used a four-stranded HG transplant pedicled to the tibia. The functional result (Lysholm knee score and subjective IKDC score), clinical result (KT-1000, Lachman test, joint amplitudes, objective IKDC score), and isokinetic complication occurrence were analyzed at six months and 12 months follow-up. The functional results, clinical parameters, and complications were analyzed at 30 months follow-up. The comparison of the variables with the various regressions was carried out by a Wilcoxon sign test. RESULTS: Twenty-one patients were reviewed at six, nine, 12, and 30 months. The mean Lysholm knee score was 90/100 at six months, 96/100 at one year, and 95/100 at 30 months. The mean subjective IKDC score was 77/100 and 89/100 at six and 12 months, and 91/100 at 30 months. The mean difference in laxity compared with the healthy knee was 1.4 mm at six months, 1.9 mm at 12 months, and 2 mm at 30 months. The objective IKDC score was A or B for all patients at 12 and 30 months. The average quadriceps strength deficit decreased from 27 to 16% between six and 12 months post-operative (p = 0.0091) and the average flexor deficit from 23 to 12% (p = 0.0084). No complications were identified. CONCLUSION: The abovementioned technique allows reaching functional, clinical, and isokinetic results comparable with the standard techniques while preserving the mechanical and biological interest of tibial insertion.

INTRODUCTION: Total knee arthoplasty (TKA) is a secure procedure with more than 90% survival at ten years. The purpose of this study was to report both clinical and radiological outcomes of TKA with a varus > 10°. The second objective was to identify risk factors for failure or bad clinical results. Our hypothesis was that results and survey are comparable to TKA with lesser deformities. METHODS: Eighty-two TKA (69 patients) between January 2004 and December 2008 with a varus > 10° were reviewed retrospectively. The endpoints were clinical (range of motion, IKS knee score, Oxford, and SF-12) and radiological (HKA post-operative and the existence of radiolucent lines or loosening at last follow-up). RESULTS: Sixty-three TKA (55 patients) were assessed with a mean follow-up of 10.9 years. The global IKS score significantly increased (p = 0.04). Seven TKA needed a revision: two for sepsis, four for aseptic loosening, and one for polyethylene wear, with an overall survival of 91.6% at ten years. For aseptic loosening, the survival rate was 94.7% at ten years. Risk factors for failure were age (p = 0.001), weight (p = 0.04), and a post-operative HKA lesser than 175° (p = 0.05) for aseptic loosening. DISCUSSION: The hypothesis was confirmed: the results showed a significant improvement of function and quality of life with a survival rate comparable to those found in the literature for greater varus but also inferior to 10°. Three risk factors have been identified suggesting increased surveillance in these cases. CONCLUSION: The results of this survey confirm the work hypothesis. Total knee arthroplasty in patients with important axial deformities is a confirmed, reliable, patient-friendly and predictable good outcome procedure.

PURPOSE: This retrospective study investigates sagittal alignment after pedicle subtraction osteotomy (PSO). The purpose was to investigate factors associated with malalignment recurrence. METHODS: Full spine radiographs were analyzed in 66 patients (average age 54.5 years, follow-up 3.8 years). Measurements were taken preoperatively, 3 months postoperatively, at follow-up: SVA C2 and C7, C2-C7 lordosis, T4-T12 kyphosis, L1-S1 lordosis, PSO lordosis, pelvic incidence, pelvic tilt, sacral slope. Follow-up CTs were screened for pseudarthrosis and gas in sacroiliac joints. RESULTS: PSO lordosis increased from 11.8° to 40.8° (p < 0.0001) and kept stable. Lumbar lordosis increased from 28.6° to 57.7° (p < 0.0001) and decreased to 49.7° (p = 0.0008). Pelvic tilt decreased from 29.2° to 16.5° (p < 0.0001) and increased to 22.5° (p < 0.0001). SVA C7 decreased from 105.1 to 35.5 mm (p < 0.0001) and increased to 64.8 mm (p = 0.0005). Twenty-eight patients (42%) had an SVA C7 increase of more than 70 mm in the postoperative course: recurrence group. These patients were older: 62.8 years versus 52.3 years (p = 0.0031). Loss of lordosis was 11.9° (recurrence group) versus 5.0° (non-recurrence group). Eleven patients (17%) had pseudarthrosis. Pelvic incidence increased by 9.3° (recurrence group) versus 3.8° (non-recurrence group). In 23 patients (35%), pelvic incidence increased > 10°. Gas was evidenced in sacroiliac joints in 22 patients (33%). CONCLUSION: Postoperative anterior malalignment recurrence may occur after PSO. Elderly patients were at risk of recurrence. Loss of lumbar lordosis linked to pseudarthrosis represented another factor. With malalignment recurrence, anterior trunk rotation and pelvic retroversion might additionally have augmented moments across sacroiliac joints with subsequent ligament laxity and pelvic incidence increase.
