A predictive score of high tibial osteotomy survivorship to help in surgical decision-making: the SKOOP score.

Introduction: The high tibial osteotomy (HTO) survival rate is strongly correlated with surgical indications and predictive factors. This study aims to assess HTO survival in the long term, to determine the main predictive factors of this survival, to propose a predictive score for HTO based on those factors.

Methods: This multicentric study included 481 HTO between 2004 and 2015.

Incidence and Risk Factors for Residual High-Grade Pivot Shift After ACL Reconstruction With or Without a Lateral Extra-articular Tenodesis.

Background: Residual rotatory knee laxity at midterm follow-up after isolated anterior cruciate ligament reconstruction (ACLR) versus ACLR with lateral extra-articular tenodesis (LET) remains an issue.

Purpose/hypothesis: To evaluate the outcomes of ACLR with or without additional LET at a minimum 2-year follow-up in patients with preoperative high-grade pivot shift (PS). Our hypothesis was that the addition of LET would decrease the risk of secondary meniscal injury and the presence of residual high-grade PS at follow-up.

Functional outcome of osteochondral autograft is equivalent in stable knee and in anterior cruciate ligament reconstruction.

Introduction: Anterior cruciate ligament (ACL) tears are associated in 10% to 20% of cases with extensive traumatic focal osteochondral damage. Ligament reconstruction may require osteochondral autograft for symptomatic osteochondral lesions. Combined ACL and chondral or osteochondral reconstruction is poorly evaluated in the literature; osteochondral reconstruction in stable knee better documented.

Is patient-specific instrumentation more precise than conventional techniques and navigation in achieving planned correction in high tibial osteotomy?

Introduction: Preoperative planning in high tibial osteotomy (HTO) is a critical step for achieving the desired correction and a clinically satisfactory outcome. Conventional radiography, navigation assistance and patient-specific instrumentation (PSI) are the 3 means of planning, but no prospective studies have compared precision between the 3. The aims of the present study were: (1) to analyze and compare correction precision between the 3 planning approaches at 1 year's follow-up; (2) to compare results to those reported in the literature; and (3) to analyze factors influencing the achievement of planned correction.

Evaluation of the "Minimal Clinically Important Difference" (MCID) of the KOOS, KSS and SF-12 scores after open-wedge high tibial osteotomy.

Purpose: Defining a Minimal Clinically Important Difference (MCID) value for Patient-Reported Outcome Measures (PROMs) is crucial for determining the effectiveness of a procedure and calculating the sample size for trial planning. The purpose of this study was to determine the MCID of several PROMs (Knee injury and Osteoarthritis Outcome Score (KOOS), Knee Society Score (KSS) and the SF-12) in patients who underwent medial opening-wedge High-Tibial Osteotomy (owHTO) with Patient-Specific Cutting Guides (PSCGs), using anchor-based methods.

Methods: Patients undergoing isolated medial owHTO with PSCGs between January 2013 and January 2017 were enrolled in this single-center, prospective, observational study.

Very long-term osteoarthritis rate after anterior cruciate ligament reconstruction: 182 cases with 22-year' follow-up.

Background: Few data are available on the 20-year outcomes of anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to assess the prevalence and risk factors of knee osteoarthritis at least 20 years after ACL reconstruction.

Hypothesis: Factors associated with progression to knee osteoarthritis include meniscal lesions, level of physical activity, injury-to-surgery time, body mass index, residual laxity, tunnel position and cartilage injury.

Multiligament knee injuries treated by one-stage reconstruction using allograft: Postoperative laxity assessment using stress radiography and clinical outcomes.

Background: Surgical treatment of multiligament knee injuries (MLKIs) leads to better outcomes but there are controversies about optimal surgical strategies. Debates remain about timing of surgery: acute, staged or delayed and about graft choice: autograft, allograft or a combination of both. Therefore, we performed a retrospective study aiming to evaluate postoperative laxity using stress radiographs and clinical outcomes after one-stage reconstructions of injured ligaments using non-irradiated, fresh-frozen allografts.

Long-Term Results for Treatment of Chronic Ankle Instability With Fibular Periosteum Ligamentoplasty and Extensor Retinaculum Flap.

Long-term results of anatomic reconstruction for chronic ankle instability are good, but no study has shown the results of fibular periosteum ligamentoplasty associated with extensor retinaculum flap at long-term follow-up. To demonstrate the efficacy of fibular periosteum ligamentoplasty and extensor retinaculum flap in chronic lateral instability, 40 patients underwent surgery for ankle instability. Thirty-three (82.

Prospective comparative study of knee laxity with four different methods in anterior cruciate ligament tears.

Background And Purpose: Anterior knee laxity can be evaluated using different devices, the most commonly used being the Telos®, KT1000®, Rolimeter®, and GNRB®. However, the laxity values obtained with these devices have never been compared to one another. As such, the outcomes of studies using these different knee laxity measurement devices may not be comparable.

Endoscopic fibular groove deepening for stabilisation of recurrent peroneal tendons instability in a patient with open physes.

This is a report of a rare case of recurrent traumatic peroneal tendon dislocation in a patient with open physes. Through fibular tendon endoscopy, an intramuscular needle was introduced under direct visualisation and implanted inferiorly to the growth plate while reclining the tendons posteriorly. A fibular groove deepening was performed in order to stabilize the tendons.

Minimally invasive trans-mediastinal endoscopic approach to insert phrenic stimulation electrodes in the human diaphragm: a preliminary description in cadavers.

Objective: Diaphragm pacing by phrenic nerve (PN) stimulation is currently used for patients with central respiratory paralysis to be weaned from mechanical ventilation. Electrodes are inserted either through bilateral thoracotomy or through four ports laparoscopy. The aim of this experimental work is to demonstrate the feasibility of trans-mediastinal bilateral implantation of PN electrodes using a flexible gastroscope introduced through a cervical incision in human cadavers.

Cervical incision thoracic endoscopic surgery: a minimally invasive endoscopic approach in thoracic surgery.

Cervical incision thoracic surgery has recently been described. Currently, there is a move to increase the role of flexible endoscopy in surgery. The use of a flexible endoscope through a natural orifice into the thoracic cavity still remains ethically doubtful.

Isolated rib metastases from renal cell carcinoma.

Osseous metastases of renal cell carcinoma (RCC) are the second most frequent location after lung metastases. They rarely present as isolated location. When isolated, resection may offer five-year survival rates of 30-60%.
