Role of nonoperative treatment in managing degenerative tears of the medial meniscus posterior root
BACKGROUND: Tears of the medial meniscus posterior root can lead to progressive arthritis, and its management has no consensus. The aim of our study was to evaluate the effect of supervised exercise therapy on patients with medial meniscus posterior root tears. MATERIALS AND METHODS: Between January 2005 and May 2007, 37 patients with this tear verified by magnetic resonance imaging (MRI) and osteoarthritis grade 1–2 by radiographic examination were treated by a short course of analgesics daily for up to 6 weeks and then as required during follow-up, as well as a 12-week supervised exercise program followed by a home exercise program. Final analysis was performed for 33 patients, average age 55.8 (range 50–62) years and average follow-up of 35 (range 26–49) months. Patients were followed up at 3, 6, and 12 months and yearly thereafter using the Lysholm Knee Scoring Scale, Tegner Activity Scale (TAS), and visual analog scale (VAS). The analysis was performed using one-way analysis of variance (ANOVA) and Pearson’s correlation coefficient to determine the relationship between Lysholm score and body mass index (BMI). RESULTS: Patients showed an improvement in Lysholm score, TAS, and VAS, which reached maximum in 6 months and later was accompanied by a decline. However, scores at the final follow-up were significantly better than the pretherapy scores. There was also a progression in arthritis as per Kellgren and Lawrence radiographic classification from median 1 preintervention to median 2 at the final follow-up. A correlation between BMI and Lysholm scores was seen (r = 0.47). CONCLUSION: Supervised physical therapy with a short course of analgesics followed by a home-based program results in symptomatic and functional improvement over a short-term follow-up; however, osteoarthritis progression continues and is related to BMI
Application of monorail fixator for femoral gap nonunion
【Abstract】Difficult femoral nonunion takes
account of infective nonunion and aseptic gap nonunion. Limb length discrepancy and nonunion need to be tackled
simultaneously. Conventionally Ilizarov ring fixator is in vogue but it has some limitations. To overcome these,
monorail fixator is an effective alternative. Persistent good results can be obtained if we can get a perfect anatomical alignment and good regeneration.

An unusual cause of radial nerve palsy
Neurapraxia frequently occurs following
traction injury to the nerve intraoperatively, leading to radial nerve palsy which usually recovers in 5-30 weeks. In our case, we had operated a distal one-third of humeral
shaft fracture and fixed it with 4.5 mm limited contact dynamic compression plate. The distal neurovascular status of the limb was assessed postoperatively in the recovery room and was found to be intact and all the sensory-motor functions of the radial nerve were normal.
On the second postoperative day, following the suction drain removal and dressing, patient developed immediate
radial nerve palsy along with wrist drop. We reviewed theliterature and found no obvious cause for the nerve palsy
and concluded that it was due to traction injury to the radial nerve while removing the suction drain in negative pressure.

Common musculoskeletal disorders in chronic liver disease patients
Chronic liver disease (CLD) is the commonest ailment affecting the hepatobiliary system. Six significant pathologies related to CLD include hepatic osteodystrophy (HO), increased infection susceptibility, sarcopenia, osteonecrosis of the femoral head (OFH), increased risk of periprosthetic complications and fracture. Hepatic osteodystrophy, which comprises osteopenia, osteoporosis, and osteomalacia, refers to alterations in bone mineral metabolism found in patients with CLD. The HO prevalence ranges from 13 to 95%. Low complement levels, poor opsonization capacity, portosystemic shunting, decreased albumin levels, and impaired reticuloendothelial system make the cirrhotic patients more susceptible to developing infectious diseases. Septic arthritis, osteomyelitis, prosthetic joint infection, and cellulitis were common types of CLD-associated infectious conditions. The incidence of septic arthritis is 1.5 to 2-fold higher in patients with cirrhosis. Sarcopenia, also known as muscle wasting, is one of the frequently overlooked manifestations of CLD. Sarcopenia has been shown to be independent predictor of longer mechanical ventilation, hospital stay, and 12-month mortality of post-transplantation. Alcohol and steroid abuse commonly associated with CLD are the two most important contributory factors for non-traumatic osteonecrosis. However, many studies have identified cirrhosis alone to be an independent cause of atraumatic osteonecrosis. The risk of developing OFH in cirrhosis patients increases by 2.4 folds and the need for total hip arthroplasty increases by 10 folds. Liver disease has been associated with worse outcomes and higher costs after arthroplasty. Cirrhosis is a risk factor for arthroplasty complications and is associated with a prolonged hospital stay, higher costs, readmission rates, and increased mortality after arthroplasty. Greater physician awareness of risk factors associated with musculoskeletal complications of CLD patients would yield earlier interventions, lower healthcare costs, and better overall clinical outcomes for this group of patients
A review of the efficacy of intraarticular hip injection for patients with hip osteoarthritis: to inject or not to inject in hip osteoarthritis?
Hip injection (HI) for osteoarthritis (OA) are in vogue nowadays. Corticosteroids (CSs) and hyaluronic acid (HA) gel are the two most common agents injected into the hip. Off late, platelet-rich plasma (PRP), mesenchymal stem cell (MSC), bone marrow aspirate concentrate (BMAC), local anesthetic (LA) agents, non-steroidal anti-inflammatory drugs (NSAIDs) and their different combinations have also been injected in hips to provide desired pain relief. However, there is a group of clinicians who vary of these injections. A search of the literature was performed on PubMed, Cochrane Library, and DOAJ using the keywords “hip osteoarthritis injection”. Data were analyzed and compiled. Intraarticular CSs are effective in providing the desired pain relief in OA hip, but repeated injections should be avoided and the interval between HI and hip arthroplasty must be kept for more than three months. Methylprednisolone or triamcinolone are combined with 1% lidocaine or 0.5% bupivacaine. Chondrotoxic effects of LA is a concern. Although national guidelines do not favor the use of HA for hip OA, numerous publications have favored its usage for a moderate grade of OA. The PRP, MSC, and BMAC are treatment options with great potential; however, currently, the evidence is conflicting on their role in hip OA. There is always a risk of septic arthritis, particularly when aseptic precautions are not followed, and clinicians must vary of this complication.
The use of hip injection (HI) in the treatment of osteoarthritis (OA) has gained wide popularity. The relatively low cost, fast and simple method of pain relief are amongst its many advantages. Over time, the content of the injection has also evolved from local anesthetic (LA) agents to corticosteroids (CSs), hyaluronic acid (HA) and platelet-rich plasma (PRP).[1] The scope of use of injections in the hip region has grown from traditional aspiration to therapeutic injections. The two main substances used in recent times for pain relief are CSs and HA gel. For decades, low doses of CS were given to surgically unfit patients and to those who are not keen on joint replacement surgery.[2]
The recent surge in the use of high-molecularweight HA for knee OA has been expanded as a treatment option for hip OA. The popularity of the administration of HA has been mounting with very little outcome data to support its use. Administration of HA injections has shown some promise in a selected subset of patients suffering from early OA of the hip.[3,4] Most papers report insufficient sample size and had a varied follow-up period which results in difficulty formulating and implementing national guidelines and clinical recommendations. Current literature advocates the safe use of CS injections for early hip OA.[5] Although there is no concrete evidence supporting HA injections, this has not dissuaded researchers from injecting PRP, mesenchymal stem cells (MSCs), LA agents, NSAIDS and many different combinations into the hip. The true extent of their benefits is still being debated.[6] In this review, we outline recent trends, discuss the role of HIs, and summarize complications of the technique
Risk factors for dislocation after bipolar hemiarthroplasty: a retrospective case–control study of patients with CT data
Purpose!#!Bipolar hemiarthroplasty has been shown to have a lower rate of dislocation than total hip arthroplasty. However, as the influencing risk factors for bipolar hemiarthroplasty dislocation remain unclear, we aimed to analyse patient and surgeon-specific influencing risk factors for bipolar hemiarthroplasty dislocation.!##!Methods!#!We retrospectively analysed patients who were operated between 2012 and 2018 and had dislocated bipolar hemiarthroplasty and matched them to patients without a dislocated bipolar hemiarthroplasty, operated between 2018 and 2019. The study was limited to patients who received either a pre- or postoperative pelvic computed tomography. Besides demographic, morphologic, and physiologic data, we analysed duration of surgery; ASA score; Charlson Comorbidity Index; Almelo Hip Fracture Score; Parker Score; and acetabular morphology angles including acetabular anteversion angle, posterior acetabular sector angle, posterior wall angle, and acetabular roofing.!##!Results!#!We included nine patients with a dislocated bipolar hemiarthroplasty and 30 with a non-dislocated bipolar hemiarthroplasty. Patient-specific factors prompting a higher risk for dislocated bipolar hemiarthroplasty were longer duration of surgery (min) (115 ± 50 vs. 80 ± 27, p = 0.01); dementia (56% vs. 13%, p < 0.01); smaller posterior acetabular sector angle (°) (96 ± 6 vs. 109 ± 10, p < 0.01); and smaller posterior wall angle (°) (67 ± 6 vs. 77 ± 10, p = 0.02).!##!Conclusion!#!Dementia and insufficient posterior wall angle were associated with higher risk of dislocation in bipolar hemiarthroplasty
