Arthroscopy with partial meniscectomy for degenerative tear does not increase the risk of total knee arthroplasty at five year follow up; however, this population undergoes total knee arthroplasty with a lower threshold of osteoarthritis.

PURPOSE: Degenerative meniscus tears can cause discomfort in some patients, and when medical treatments fail to provide relief, arthroscopy may be considered before resorting to knee prosthesis. However, the benefits of arthroscopy over nonsurgical treatments in patients over 60 years old are limited, and the evidence regarding its overall efficiency and drawbacks remains scarce. Furthermore, there has been no investigation into whether those patients treated with partial meniscectomy, undergo the knee operation at an earlier stage of osteoarthritis. METHODS: This study focused on data from a single Belgian hospital, involving patients over 60 years old with internal meniscal tears. The participants were categorized into two groups based on the treatment they received: arthroscopic partial meniscectomy (APM) or conservative management. The primary outcome assessed was the occurrence of knee arthroplasty within a five year period. Secondary outcomes included evaluating the ICRS cartilage grade and the time taken until total knee arthroplasty (TKA). RESULTS: A total of 194 patients with internal meniscal tears were included in the study. At the 5-year mark, the overall rate of knee arthroplasty was found to be 16.5%, with 11.9% of cases occurring within two years. After the 5-year follow-up, it was observed that 19.2% (24 patients) of the APM group and 11.6% (8 patients) of the conservative management group underwent knee arthroplasty. Notably, patients over 70 years old who underwent APM had a higher risk of eventually requiring TKA compared to those who received conservative management. Additionally, patients who underwent meniscectomy and later underwent TKA showed less wear in the internal compartment of the knee compared to patients in the conservative treatment group who underwent TKA. CONCLUSION: The study suggests that patients who underwent arthroscopy faced a similar risk of knee arthroplasty compared to those who underwent conservative management, excepted for patients over 70 years old. Despite this similar risk of arthroplasty for the whole population, they exhibited lower osteoarthritis severity when compared to the conservative group.

The posterior cruciate ligament-posterior femoral cortex angle (PCL-PCA) and the lateral collateral ligament (LCL) sign are useful parameters to indicate the progression of knee decompensation over time after an ACL injury.

PURPOSE: The posterior cruciate ligament-posterior cortex angle (angle between the most vertical part of the anterolateral PCL bundle and the posterior diaphyseal cortex of the femur; PCL-PCA) is the most accurate approach to describe the PCL buckling phenomenon observed in anterior cruciate ligament (ACL)-deficient knees. The aim of this study was to determine whether the PCL-PCA is associated with chronicity of the ACL rupture, the meniscal status, preoperative knee laxity or imaging signs such as the lateral collateral ligament (LCL) sign or the posterior tibial slope (PTS) in ACL-injured knees. METHODS: Patients with a primary ACL reconstruction (ACLR) after physeal closure were selected retrospectively from a hospital-based ACL registry from 2015 to 2021. Exclusion criteria were: previous ipsilateral/contralateral knee surgery, previous ipsilateral ACL or meniscal tear, ipsilateral PCL and/or collateral ligament injuries or tibial plateau fracture. The ACL deficiency was defined as chronic if time from injury to MRI was > 6 months. The meniscal status was assessed during ACLR, separately for the medial and lateral meniscus, and classified into no tear, minor or major unstable tear. The MRI analyses included the assessment of the PCL-PCA and the LCL sign. PTS was assessed from the lateral plain radiographs of the injured knee. The side-to-side difference in anterior tibial translation (ATT) at 200N was obtained with the GNRB. RESULTS: Eighty-two patients (forty-eight males/thirty-four females) were included in this study. The median PCL-PCA was 16.2° (Q1-Q3: 10.6-24.7) and differed between acute (18.4°) and chronic (10.7°) injuries (p < 0.01). The median PCL-PCA was significantly lower (- 4.6°) in patients with a positive LCL sign (p = 0.03) No significant association could be found between PCL-PCA and meniscal status, PTS or preoperative anterior knee laxity (Lachman, pivot shift and ATT in millimetres). CONCLUSION: The PCL-PCA was significantly lower in chronic ACL injuries and in patients with a positive LCL sign, indicating a higher buckling phenomenon of the PCL in these patients. These results support the fact that PCL-PCA and the LCL sign may be useful parameters to indicate the progression of knee decompensation over time after an ACL injury, and therefore may constitute a helpful tool to optimise treatment choice and timing of ACL reconstruction if necessary. LEVEL OF EVIDENCE: III.

Hip fractures re-operation compared with death at two year in elderly patients: lowest risk of revision with dual mobility total hip arthroplasty than with bipolar hemiarthroplasty or internal fixation of Garden I and II.

PURPOSE: This study determined at two year follow-up the lifetime risk of re-operation for elderly patients with hip fractures undergoing internal fixation, dual mobility total hip arthroplasty, or bipolar hemiarthroplasty, using death of the patient as a competing risk. MATERIALS AND METHODS: With the hypothesis that arthroplasties may have less complications without increasing mortality even for Garden I and Garden II fractures, we retrospectively reviewed 317 hips with femoral neck fractures operated between January 2015 and August 2019. The mean age at time of surgical intervention was 82.4 years (range 65 to 105). Sixty patients presented a nondisplaced hip fracture (Garden I or II) treated by internal fixtion (I-F), and 257 were treated by hip arthroplasty: 118 dual mobility total hip arthroplasty (DM-THA) and 139 with a bipolar hemiarthroplaty (B-H). Demographics, surgical and complications data, and mortality were collected and compared for each group. RESULTS: The overall mortality rate was 22.4% at two years, and similar (p = 0.98) in all groups, respectively 22%, 22%, and 23% for DM-THA, B-H, and I-F groups. With dual mobility THA, the cumulative incidence of re-operations for any reason was (lower (9%) than with internal fixation (22%) or bipolar hemiarthroplasties (19%). CONCLUSION: Using a double mobility total prosthesis does not increase the post-operative mortality of the patients, nor does it increase their survival. But, reducing the risk of complications certainly improves their quality of life during the little time they have left .

Adverse local tissue reaction after ceramic-on-ceramic total hip arthroplasty.

We report a rare case of symptomatic adverse local tissue reaction in a patient with a ceramic-on-ceramic total hip bearing surface and review the literature. Probably, ceramic wear debris is not entirely inert and may lead to adverse local tissue reactions.

Long-term follow-up of the incisional hernia rate after single-incision laparoscopic cholecystectomy: a prospective observational study.

PURPOSE: To evaluate the long-term occurrence rate of incisional hernias following single-incision laparoscopic cholecystectomy (SILC). BACKGROUND: Since the 90 s, SILC has emerged as a less invasive alternative to standard laparoscopic cholecystectomy in selected patients. But concerns over port-incisional hernias have not been addressed. METHODS: Between February 2009 and February 2011, 142 patients referred for gallstones who agreed to undergo SILC were included in a monocenter prospective observational study. All of the procedures were carried out using a single-port access technique. The occurrence rates of incisional hernias were analyzed with the Kaplan-Meier actuarial method. Statistical significance was set at p < .05. RESULTS: A total of 142 patients with gallbladder pathology were included in the study; 138 of them underwent SILC and 4 were converted to standard multiport cholecystectomy. Twelve patients (8%) were found to have developed a port-site incisional hernia (PSH) by physical examination or by imaging. The Kaplan-Meier curve showed that the rate of PSH development was 83% in the first 2 years after surgery. After 2 years, this risk becomes quite low. CONCLUSIONS: Our results indicate that the SILC procedure is a safe option for treatment of benign gallbladder diseases for selected patients, albeit with a high incisional hernia rate.

Post-COVID-19 return to elective orthopaedic surgery-is rescheduling just a reboot process? Which timing for tests? Is chest CT scan still useful? Safety of the first hundred elective cases? How to explain the "new normality health organization" to patients?

PURPOSE: The long incubation period and asymptomatic spread of COVID-19 present considerable challenges for health care institutions when patients return to elective surgery. METHODS: A retrospective review of the first adult elective cases performed between May 18, 2020 and June 14, 2020, after the end of lockdown was analysed in Belgium to answer the following questions: (1) for the 236 cancelled patients during the outbreak, how easy was rescheduling? (2) How useful was universal RT-PCR testing and chest CT scan for the 211 orthopaedic and trauma admissions? (3) How were surgical difficulty category, number of operations and complications different when compared to the pre-COVID period? (4) How would patients balance the benefit of surgery against the unknown risk of developing COVID-19? RESULTS: Before surgery, blood tests for anaesthesiology and imaging related to the surgical procedure were scheduled prior to universal testing (COVID-19 PCR and chest CT) performed 72-120 hours before surgery. Among the 211 asymptomatic patients who were tested before surgery, six had positive PCR, while no abnormality was found on the chest CT scan of all the patients. With this timing for tests, the 104 patients included in the current study for elective surgery were free of disease before undergoing surgery and remained without COVID-19 after surgery. Among the 366 cancelled patients during the outbreak, only 12% of the patients accepted to proceed with rescheduling immediately. Therefore, this resulted in a 70% reduction for elective surgery and in a 50% reduction for arthroplasties as compared to pre-COVID period. The rate of complications was not increased during the post-COVID period. A portion of patients have confused idea of screening and have difficulty to perceive the new rules of health organization. CONCLUSIONS: Resumption of elective surgical procedures appears more difficult for patients than for surgeons with a low percentage of cancelled patients accepting to reschedule surgery. Universal testing allowed securing patients; however, surgeons must explore better patient perceptions regarding COVID-19 to facilitate a fully informed decision in the current period.

Nonanatomic Posteromedial Bundle Augmentation of the Posterior Cruciate Ligament after Hyperextension Trauma.

The surgical management of posterior cruciate ligament (PCL) injuries can be challenging. As most PCL injuries occur in a flexed knee position, the anterolateral bundle is thought to be more commonly injured than the posteromedial bundle (PMB); however, in hyperextension, the PMB plays a more significant role. The smaller size of the PMB compared with the anterolateral bundle and its lower strength may explain why isolated hyperextension PMB injuries can be easily overlooked. In this Technical Note, a surgical technique to perform a nonanatomic PMB augmentation of the PCL using a gracilis tendon autograft or allograft is reported. These technical features aim to overcome current limitations in existing techniques to address the symptoms after partial PCL hyperextension injuries.

Case report: unusual posteromedial capsular lesion with posterior lateral meniscus root tear in two patients with constitutional genu recurvatum presenting after an acute ACL injury.

Ramp lesions of the medial meniscus and posterior lateral meniscus root tears (LMPRT) can be present simultaneously in up to 8% of patients undergoing anterior cruciate ligament (ACL) reconstruction. The prevalence of these complex and highly unstable meniscal tears increases exponentially with the severity of the injury. The posteromedial capsule (PMC) has often been disregarded in the past when discussing ligamentous and meniscal injuries, but the recent interest in ramp lesions has drawn surgeons' attention to the posteromedial structures of the ACL injured knee. While the meniscocapsular junction is commonly repaired in unstable ramp lesions, in the current literature there is no report regarding proximal PMC lesions, be they in isolation or associated with complex meniscal injuries.We report here two cases of proximal posteromedial capsular lesions associated with medial meniscus instability and posterior lateral root tears after ACL injury. The first case involves a meniscus ramp lesion associated with a proximal PMC tear and a posteromedial fluid collection in the muscle plane on magnetic resonance in a 22-year-old male soccer player. The second case involves a 21-year-old female soccer player who presented with a PMC lesion after hyperextension/valgus knee injury. The capsular lesions were repaired to restore capsular tension and improve medial meniscus posterior horn stability.

Acute total hip replacement by direct anterior approach combined with intrapelvic fixation for geriatric acetabular fracture of the anterior column.

Management of anterior column acetabular fracture in the elderly is challenging. Open reduction and internal fixation do not allow early weight bearing and are associated with a high risk of failure compared to younger patients. Therefore, acute fixation and total hip arthroplasty may be an option. This technical note describes a combined procedure: anterior intrapelvic approach for fracture fixation and a direct anterior approach to the hip for THR. Fracture reduction and arthroplasty were achievable in all five patients. The mean operative time was 289min, and the mean blood loss was 2120mL. At short term, no complication was noticed. Combining these two "muscle-sparing" approaches could help manage anterior column fractures in elderly patients. Level of evidence: IV.

Meniscal Ramp Repair: Double-Row Anatomic Repair in Acute Anterior Cruciate Ligament Tears.

The surgical management of medial meniscus ramp lesions can be challenging. Currently, repairs are performed via a trans-notch view, combined with a single posteromedial working portal. This technique, however, does not allow for a direct and complete visualization of the structures being injured, making a precise appreciation of the injured structures, as well as an anatomical repair, difficult. To overcome this limitation, a 2-portal posteromedial approach has recently been described. It allows better visualization of the mediolateral extent of the tear and a precise identification of the injured structures. In this Technical Note, an anatomic repair technique using this approach is presented. It consists of a double-row of sutures to repair individually both the meniscotibial and meniscocapsular ligament, thus restoring the 2 main components of the posterior horn of the medial meniscus to their natural insertion site.

A systematic approach to managing complications after proximal tibial osteotomies of the knee.

Proximal tibial osteotomy (PTO) is an effective procedure for active and young adult patients with symptomatic unicompartmental osteoarthritis and malalignment. They were considered technically demanding and prone to various complications related to the surgical technique, biomechanical or biological origin. Among the most important are hinge fractures and delayed or non-healing, neurovascular complications, loss of correction, implant-related problems, patellofemoral complaints, biological complications and changes in limb length. Being aware of these problems can help minimizing their prevalence and improve the results of the procedure.The aim of this narrative review is to discuss the potential complications that may occur during and after proximal tibial osteotomies, their origin and ways to prevent them.

Effects of humeral shortening on the three-dimensional configuration of the brachial plexus: a cadaveric study.

This study reports the gains in length of nerves after three different humeral shortenings. Ten brachial plexuses were dissected. The lengths of the different parts of the brachial plexus were measured using a three-dimensional digitizing system after humeral shaft shortenings of 2, 4 and 6 cm and after a standardized force of 0.588 N was used to apply tension to the plexus. The feasibility of nerve suturing was studied. Humeral shortening allowed for significant gains in lengths of the musculocutaneous (42 mm), median (41 mm), ulnar (29 mm) and radial nerves (15 mm). A 2 cm humeral shortening allowed a 2 cm nerve gap to be directly sutured in 70% to 90% of cases. This study suggests that humeral shortening could allow direct suture of nerve defects, or shorten the length of nerve grafts required to bridge a gap.
