A biopsychosocial approach to phenotyping people with knee osteoarthritis awaiting total knee arthroplasty: A secondary cohort analysis.

Background: Previous research showed chronic post-total knee arthroplasty (TKA) pain in 20% of people with knee osteoarthritis (KOA). Various preoperative biopsychosocial-related factors have been described, but phenotyping people with KOA awaiting TKA based on these factors is still lacking. This could be relevant to understanding differences in TKA surgery responses.

Preoperative glycaemic control, number of pain locations, structural knee damage, self-reported central sensitisation, satisfaction and personal control are predictive of 1-year postoperative pain, and change in pain from pre- to 1-year posttotal knee arthroplasty.

Purpose: The aim of this study was to identify preoperative predictors for 1-year posttotal knee arthroplasty (TKA) pain and pre- to post-TKA pain difference in knee osteoarthritis (KOA) patients.

Methods: From March 2018 to July 2023, this prospective longitudinal cohort study enrolled KOA patients awaiting TKA from four hospitals in Belgium and the Netherlands. Different biopsychosocial predictors were assessed preoperatively by questionnaires and physical examinations (input variables).

Prehabilitation before total knee arthroplasty: A systematic review on the use and efficacy of stratified care.

Background: Preoperative rehabilitation (hereafter called "prehabilitation") has been proposed as a potentially effective treatment to target preoperative risk factors to prevent insufficient outcome after total knee arthroplasty (TKA).

Purpose: We aimed to assess whether previous clinical trials of non-surgical, non-pharmacological prehabilitation in individuals with knee osteoarthritis (KOA) awaiting TKA focused on specific clinical phenotypes or specific individual characteristics and whether the content of the prehabilitation was stratified accordingly. Second, we aimed to summarize and compare the long-term effects of stratified and non-stratified care on pain, satisfaction, function and quality of life.

Long-term results after ulnar collateral ligament reconstruction of the elbow in European athletes with interference screw technique and triceps fascia autograft.

Background: In the last decade, there has been increasing interest in medial ulnar collateral ligament (MUCL) reconstruction techniques for MUCL insufficiency of the elbow. All case series are based on American and Asian Athletes and use primarily a palmaris longus tendon or gracilis tendon as an autograft in reconstructions. A new technique is the interference screw fixation.

The posterior transtriceps approach for intra-articular elbow diagnostics, definitely not forgotten.

Background/aims: The elbow is among the most common joints that are aspirated and/or injected. An intra-articular approach should be a convenient and a safe procedure with minimal risk of complications. Several approaches to access the elbow joint have been outlined in the literature, but a comparative study is lacking.

Arthroscopic treatment of posterior impingement of the elbow in athletes: a medium-term follow-up in sixteen cases.

Hypothesis: Evaluate the effectiveness of arthroscopic treatment of posterior impingement in the athletes elbow.

Materials And Methods: 16 elbows were included. An arthroscopic debridement of the posterior fossa of the elbow was performed.

Results of arthroscopic debridement for osteochondritis dissecans of the elbow.

Objective: To determine the clinical outcome of arthroscopic debridement for osteochondritis dissecans of the elbow.

Methods: A prospective cohort study was started in 2000; between 2000 and 2005, 15 patients (six male, nine female, mean age 28 years (range 16-49)) were treated for osteochondritis dissecans of the elbow with arthroscopic debridement. The lesion was graded during surgery using the classification of Baumgarten.

Treatment of sequelae of radial head fractures with a bipolar radial head prosthesis: good outcome after 1-4 years follow-up in 11 patients.

Background: In the presence of additional disruption of the distal radioulnar ligaments, the interosseous membrane, or the lateral- and/or medial collateral ligament, radial head fractures treated by resection will result in valgus elbow instability, proximal radial migration and/or posterolateral rotatory instability. Radial head replacement has been used to treat or prevent this. We report our experience with the Judet CRF II radial head prosthesis.

Nonsteroidal anti-inflammatory drugs and acetaminophen in the treatment of an acute muscle injury.

Background: Nonsteroidal anti-inflammatory drugs are frequently used to treat muscle injuries in athletes. It is not known whether the anti-inflammatory effects of these drugs are important or whether their effectiveness is a result of their central analgesic effect.

Hypothesis: The effects of nonsteroidal anti-inflammatory drugs are no different than the effects of an analgesic (acetaminophen) without anti-inflammatory action in an experimental, acute muscle contusion model.

Knee stability following anterior cruciate ligament rupture and surgery. The contribution of irreducible tibial subluxation.

Background: Knee stability after anterior cruciate ligament reconstruction is generally determined by measuring total anteroposterior tibial motion. In spite of a decrease in excessive anteroposterior tibial motion after anterior cruciate ligament reconstruction, problems can still develop. In the present study, we sought to define the tibiofemoral relationship more accurately with use of stress radiographs of human knees after anterior cruciate ligament rupture and after anterior cruciate ligament reconstruction.

Sentinel node biopsy for nonpalpable breast tumors requires a preoperative diagnosis of invasive breast cancer.

A sentinel node biopsy done at the time of initial tumor resection allows for a one-stage surgical procedure. In addition, sentinel node identification may be impaired when done after a previous tumor excision. This study evaluates the sentinel node biopsy in patients with nonpalpable breast cancer and assesses whether a sentinel node biopsy for mammographically suspect breast lesions is justified when preoperative needle biopsy is inconclusive for invasive malignancy.

Ultrasound-guided lumpectomy of nonpalpable breast cancer versus wire-guided resection: a randomized clinical trial.

Background: The wire-guided excision of nonpalpable breast cancer often results in tumor resections with inadequate margins. This prospective, randomized trial was undertaken to investigate whether intraoperative ultrasound (US) guidance enables a better margin clearance than the wire-guided technique in the breast-conserving treatment of nonpalpable breast cancers.

Methods: Patients with a preoperative histological diagnosis of nonpalpable breast cancer that could be visualized both with US and mammography were included.

Multiple fibroadenomas harbouring carcinoma in situ in a woman with a family history of breast/ovarian cancer.

A 46 year old woman with a family history of breast and ovarian cancer presented with multiple fibroadenomas in both breasts. From three fibroadenomas removed from the left breast carcinoma in situ (CIS) had developed. One fibroadenoma gave rise to ductal CIS, whereas the other two harboured lobular CIS.

Predictive factors for metastatic involvement of nonsentinel nodes in patients with breast cancer.

Background: The potential morbidity of an axillary lymph node dissection in patients with breast cancer can be avoided in patients with a negative sentinel node (SN).

Hypothesis: It may be possible to identify a subset of patients with a positive SN and without metastases in the remaining axillary lymph nodes.

Design: Case-control study.

Sentinel node investigation in breast cancer: detailed analysis of the yield from step sectioning and immunohistochemistry.

Aims: To evaluate in detail the extent to which step sectioning and immunohistochemical examination of sentinel lymph nodes (SNs) in patients with breast cancer reveal additional node positive patients, to arrive at a sensitive yet workable protocol for histopathological SN examination.

Methods: This study comprised 86 women with one or more positive SN after a successful SN procedure for clinical stage T1-T2 invasive breast cancer. SNs were lamellated into pieces of approximately 0.

The implementation of the sentinel node biopsy as a routine procedure for patients with breast cancer.

Background: The sentinel node procedure for breast cancer allows for accurate staging of the axilla while the axillary node dissection can be avoided in patients with no sentinel node metastasis. This study describes those patients in whom an axillary dissection is performed, depending on the outcome of the sentinel node procedure, with particular emphasis on the use of strict criteria for the procedure and its practical limitations.

Methods: Preoperative lymphoscintigraphy was performed in 115 consecutive patients.

"Dog ear" formation after double-stapled low anterior resection as a risk factor for anastomotic disruption.

Purpose: The aim of this study was to investigate the possible deleterious effect of the lateral intersecting margins (so-called dog ears) on anastomotic disruption after experimentally performed double-stapled anastomoses.

Methods: Two groups of double-stapled side-to-end anastomoses were performed using pig small intestines. Group A consisted of 35 circular anastomoses and Group B of 32 double-stapled anastomoses with a bilateral dog ear.

Ultrasound-guided lumpectomy of nonpalpable breast cancers: A feasibility study looking at the accuracy of obtained margins.

Background And Objectives: Complete excision of a nonpalpable breast cancer after wire localization is a difficult procedure. Often, adequate margins are not obtained, and a second procedure is then required. Prospectively, we studied the feasibility of ultrasound-guided excisions of nonpalpable breast cancers, with particular attention to the accuracy of the procedure in obtaining adequate margins.

Palliative cryosurgery for rectal carcinoma.

Cryosurgery is one of the palliative treatment options to decrease local symptoms due to rectal carcinoma. A total of 106 patients (aged 45-92 years) underwent palliative cryosurgery for primary rectal cancer. Inclusion criteria were prohibitive surgical risk, unresectability, distant metastases, patient refusal of surgical intervention, and old age.

Selection of patients for resection of colorectal metastases to the liver using diagnostic laparoscopy and laparoscopic ultrasonography.

Objective: To assess the value of diagnostic laparoscopy (DL) and laparoscopic ultrasonography (LUS) in the staging and selection of patients with colorectal liver metastasis.

Summary Background Data: Preoperative imaging modalities such as ultrasound, computed tomography, and magnetic resonance imaging are limited in the assessment of the number and exact location of hepatic metastases and in the detection of extrahepatic metastatic disease. Consequently, the surgeon is often faced with a discrepancy between preoperative imaging results and perioperative findings, resulting in either a different resection than planned or no resection at all.

Reliability of intraoperative frozen section and imprint cytological investigation of sentinel lymph nodes in breast cancer.

Aims: The sentinel lymph node procedure enables selective targeting of the first draining lymph node, where the initial metastases will form. A negative sentinel node (SN) predicts the absence of tumour metastases in the other regional lymph nodes with high accuracy. This means that in the case of a negative SN, regional lymph node dissection is no longer necessary.
