Lesions of the rotator cuff (RC) are a common occurrence affecting millions of people across all parts of the globe. RC tears are also rampantly prevalent with an age-dependent increase in numbers. Other associated factors include a history of trauma, limb dominance, contralateral shoulder, smoking-status, hypercholesterolemia, posture and occupational dispositions. The challenge lies in early diagnosis since a high proportion of patients are asymptomatic. Pain and decreasing shoulder power and function should alert the heedful practitioner in recognizing promptly the onset or aggravation of existing RC tears. Partial-thickness tears (PTT) can be bursal-sided or articular-sided tears. Over the course of time, PTT enlarge and propagate into full-thickness tears (FTT) and develop distinct chronic pathological changes due to muscle retraction, fatty infiltration and muscle atrophy. These lead to a reduction in tendon elasticity and viability. Eventually, the glenohumeral joint experiences a series of degenerative alterations - cuff tear arthropathy. To avert this, a vigilant clinician must utilize and corroborate clinical skill and radiological findings to identify tear progression. Modern radio-diagnostic means of ultrasonography and magnetic resonance imaging provide excellent visualization of structural details and are crucial in determining further course of action for these patients. Physical therapy along with activity modifications, anti-inflammatory and analgesic medications form the pillars of nonoperative treatment. Elderly patients with minimal functional demands can be managed conservatively and reassessed at frequent intervals. Regular monitoring helps in isolating patients who require surgical interventions. Early surgery should be considered in younger, active and symptomatic, healthy patients. In addition to being cost-effective, this helps in providing a functional shoulder with a stable cuff. An easily reproducible technique of maximal strength and sturdiness should by chosen among the armamentarium of the shoulder surgeon. Grade 1 PTTs do well with debridement while more severe lesions mandate repair either by trans-tendon technique or repair following conversion into FTT. Early repair of repairable FTT can avoid appearance and progression of disability and weakness. The choice of surgery varies from surgeon-to-surgeon with arthroscopy taking the lead in the current scenario. The double-row repairs have an edge over the single-row technique in some patients especially those with massive tears. Stronger, cost-effective and improved functional scores can be obtained by the former. Both early and delayed postoperative rehabilitation programmes have led to comparable outcomes. Guarded results may be anticipated in patients in extremes of age, presence of comorbidities and severe tear patters. Overall, satisfactory results are obtained with timely diagnosis and execution of the appropriate treatment modality.

Smartphones have emerged as essential tools providing assistance in patient care, monitoring, rehabilitation, communication, diagnosis, teaching, research and reference. Among innumerable communication apps, WhatsApp has been widely popular and cost effective. The aim of our study was to report the impact of introduction of a smartphone app "WhatsApp" as an intradepartmental communication tool on (1) awareness of patient-related information, (2) efficiency of the handover process and (3) duration of traditional morning handovers among orthopedic residents in a 300-bedded tertiary care teaching center. Written handovers and paging used for communication at our center led to occasional inefficiencies among residents. Widespread use, low cost, availability and double password protection (phone lock and WhatsApp lock) made WhatsApp's group conversation feature an ideal tool for intradepartmental patient-related communication. Twenty-five consecutive admissions before and after WhatsApp (BW, AW) were included in the study. Eight orthopedic residents attempted fifty randomly arranged questions based on the twenty-five patients in each study period. A null hypothesis that introduction of WhatsApp group would neither increase the awareness of patient-related information nor improve the efficiency of the handovers among residents was assumed. A significant improvement observed in scores obtained by residents in the AW group led to rejection of the null hypothesis. The residents also reported swifter and efficient handovers after the introduction of WhatsApp. Our results indicate that the introduction of a smartphone app "WhatsApp" as an intradepartmental communication tool can bring about an improvement in patient-related awareness, communication and handovers among orthopedic residents.

Clinicians and researchers are confounded by the various outcome measures used for the assessment of carpal tunnel syndrome (CTS). In this study, we critically analysed the conceptual framework, validity, reliability, responsiveness and appropriateness of some of the commonly used CTS outcome measures. Initially, we conducted an extensive literature search to identify all of the outcome measures used in the assessment of CTS patients, which revealed six different carpal tunnel outcome measures [Boston Carpal Tunnel Questionnaire (BCTQ), Michigan Hand Outcome Questionnaire (MHQ), Disability of Arm, Shoulder and Hand (DASH), Patient Evaluation Measure (PEM), clinical rating scale (Historical-Objective (Hi-Ob) scale) and Upper Extremity Functional Scale (UEFS)]. We analysed the construction framework, development process, validation process, reliability, internal consistency (IC), responsiveness and limitations of each of these outcome measures. Our analysis reveals that BCTQ, MHQ and PEM have comprehensive frameworks, good validity, reliability and responsiveness both in the hands of the developers, as well as independent researchers. The UEFS and Hi-Ob scale need validation and reliability testing by independent researchers. Region-specific measures like DASH have good frameworks and, hence, a potential role in the assessment of CTS but they require more validation in exclusive carpal tunnel patients.

Background One of the rare complications of primary total knee arthroplasty is intra-operative fracture. Intra-operative fracture during revision knee arthroplasty has been well-documented but there is limited literature on fractures occurring during primary knee arthroplasty. We conducted a systematic review of the literature to compare and contrast the various studies to clearly define the predisposing factors, incidence, and characteristics of the fracture itself and to arrive at a consensus on the management and prevention of intra-operative fractures during primary knee arthroplasty. Methods The PubMed/Medline, Cochrane, Scopus and Embase databases were searched using keywords “intra-operative fracture”, “distal femoral fracture”, “tibial fracture”, “patella fracture” and “primary total knee arthroplasty”. A total of 158 articles were retrieved and after further filtration and exclusion processing, 10 articles that evaluated intra-operative fractures in primary total knee arthroplasty were included for the review. Results The reported incidence of intra-operative fractures varied from 0.2% to 4.4%. A higher incidence in female patients with a male to female ratio of 0.4 was reported. Posterior stabilized (PS) total knee arthroplasty was associated with higher risk of intra-operative femoral fractures by many authors in this review. Timing of occurrence and location of the intra-operative fractures can vary widely, with femoral fractures occurring more commonly during bone preparation, trialing and impaction of the final implant and tibial fractures occurring during preparation for the tibial keel and impaction of the tibial component. Conclusions Intra-operative fractures during primary total knee arthroplasty are rare with higher risk associated with osteoporosis, rheumatoid arthritis, advanced age, female gender, chronic steroid use, metabolic bone disorders, PS type of femoral implant and difficult surgical exposure of the knee joint due to severe deformities. A plethora of management options have been utilized according to surgeon preference. Standard principles of fracture fixation and arthroplasty principles should be followed to achieve stable internal fixation and any unstable fracture site should be bypassed with the utilization of stemmed components. Satisfactory radiographic and functional outcome can be expected with appropriate treatment.

Unexpected positive intraoperative culture (UPIC) in revision hip and knee arthroplasty has a prevalence of 10.5%, there is no consensus in the literature on how to interpret them and how to treat them. Our literature review showed that most authors would consider two or more positive cultures as significant and usually treat them with culture specific antibiotics for 4-6 weeks. A single positive intraoperative culture can or cannot be significant depending on the virulence of the organism, hence taking multiple tissue samples in and around the joint is recommended. All failed arthroplasty cases must be evaluated preoperatively according to musculoskeletal infection society criteria (MSIS) to rule out the possibility of infection as an etiology for failure of the arthroplasty. Most authors reported that large majority of these UPIC were from a low virulence organism. Our review showed that the implant survival is more than 85% with 4-6 weeks of antibiotic treatment.
