Purpose: Because of the concerns regarding residency process during the pandemic, this study aimed to investigate the volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room.

Methods: This retrospective chart study evaluated variables such as volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room, from an orthopaedic department in a tertiary trauma center throughout the COVID-19 pandemic era. Comparing these measures was an indirect evaluation tool for measuring the amount of work completed and clinical exposure gained by the residents.

Background: Transmetatarsal amputation (TMA) is a well-recognized limb-salvage procedure, often indicated for the treatment of diabetic foot infections. Currently, there is no widespread agreement in the literature with regard to the factors associated with failure of TMA. This study aimed to define risk factors for the failure of TMA, defined as below-the-knee or above-the-knee amputation, in patients with diabetes.

Complex statistical approaches are increasingly being used in the orthopaedic literature, and this is especially true in the field of sports medicine. Tools such as machine learning provide the opportunity to analyze certain research areas that would often require the complex assessment of large amounts of data. Generally, decision making is multifactorial and based upon experience, personal capabilities, available utilities, and literature.

Purpose: To identify radiographic measurements and demographics that are predictive of acetabular cartilage damage in patients with femoroacetabular impingement syndrome (FAIS) undergoing hip arthroscopy. More specifically, to compare the predictive value of alpha angle and femoral head-neck offset, as measured on Dunn view radiographs, in determining the preoperative likelihood and severity of acetabular cartilage damage.

Methods: Patients were included if they underwent primary hip arthroscopy for FAIS between February 2008 and June 2020.

Over the years total hip arthroplasty had turned from a procedure indicated for elderly, low functioning patients, into a procedure indicated also for younger patients who are interested in a well-functioning hip joint to maintain their active lifestyle. Previously, posterior approach was most commonly utilized, however in recent years, due to the accumulating evidence regarding the advantages of the anterior approach, an increase in the prevalence of the anterior approach is noted. In contrast to other surgical approaches, the anterior approach "respects" inter-muscular and inter-nervous planes and therefore is perceived as associates with less pain, faster rehabilitation, and a good stability relative to other approaches.

Osteoarthritis is characterized by marked pain, stiffness and reduced range of motion and is one of the most common causes of disability and reduced quality of life. The disease is diagnosed in 20% of the adult population; the prevalence rises to 50% of adults over 65 years of age. There are various treatment options in the early stages of knee osteoarthritis which are intended to postpone the need for arthroplasty, which is the gold standard treatment at the end-stage level of the disease.

Reverse shoulder arthroplasty (RSA) in its modern design was first introduced over 25 years ago and approved by the American FDA over ten years ago. This type of prosthesis allows treatment of glenohumeral joint disease among patients with severe rotator cuff deficiency once thought to be inoperable. Modifications to the prosthesis design, along with improved surgical technique, led to better clinical outcomes and lower complication rates, which subsequently led to an increase in the usage of this implant device.

Background: Spontaneous osteonecrosis of the knee is usually verified by magnetic resonance imaging accompanied by clinical questionnaires to assess the level of pain and functional limitation. There is a lack however, in an objective functional test that will reflect the functional severity of spontaneous osteonecrosis of the knee. The purpose of the current study was to examine the correlation between spatiotemporal gait parameters and clinical questionnaires in patients with spontaneous osteonecrosis of the knee.

The meniscus has an important biomechanical role in the normal function of the knee including load bearing, shock absorption and joint stability. Tears of the meniscus are one of the common sports injuries. The knowledge that total meniscectomy causes early development of degenerative changes has raised the prevalence of meniscal tear repair in order to preserve as much as possible of the meniscal tissue.

Current pain treatment guidelines advise against providing analgesics for postoperative pain using intramuscular injections, as this generally provides poor pain relief. However, this route remains the most prevalent treatment method. Intravenous or epidural patient-controlled-analgesia methods reduce pain effectively but are expensive, labor intensive, and available to only a limited number of patients.

The blood supply of one femoral head of 6-month-old rats was severed by incising the periosteum of the neck and cutting the ligamentum teres. The rats were killed on the 30th postoperative day and the femoral bones were obtained for semiquantification of the reparative processes in the necrotic heads. Fourteen rats were treated with enoxaparin and 14 untreated animals served as controls.
