Non-operative management of shoulder osteoarthritis: Current concepts.

Glenohumeral osteoarthritis (OA) is one of the most common causes of shoulder pain. Conservative treatment options include physical therapy, pharmacological therapy, and biological therapy. Patients with glenohumeral OA present shoulder pain and decreased shoulder range of motion (ROM). Abnormal scapular motion is also seen in patients as adaptation to the restricted glenohumeral motion. Physical therapy is performed to (1) decrease pain, (2) increase shoulder ROM, and (3) protect the glenohumeral joint. To decrease pain, it should be assessed whether the pain appears at rest or during shoulder motion. Physical therapy may be effective for motion pain rather than rest pain. To increase shoulder ROM, the soft tissues responsible for the ROM loss need to be identified and targeted for intervention. To protect the glenohumeral joint, rotator cuff strengthening exercises are recommended. Administration of pharmacological agents is the major part next to physical therapy in the conservative treatment. The main aim of pharmacological treatment is the reduction of pain and diminution of inflammation in the joint. To achieve this aim, non-steroidal anti-inflammatory drugs are recommended as first-line therapy. Additionally, the supplementation of oral vitamin C and vitamin D can help to slow down cartilage degeneration. Depending on the individual comorbidities and contraindications, sufficient medication with good pain reduction is thus possible for each patient. This interrupts the chronic inflammatory state in the joint and, in turn, enables pain-free physical therapy. Biologics such as platelet-rich plasma, bone marrow aspirate concentrate, and mesenchymal stem cells have gathered increased attention. Good clinical outcomes have been reported, but we need to be aware that these options are helpful in decreasing shoulder pain but neither stopping the progression nor improving OA. Further evidence of biologics needs to be obtained to determine their effectiveness. In athletes, a combined approach of activity modification and physical therapy can be effective. Oral medications can provide patients with transient pain relief. Intra-articular corticosteroid injection, which provides longer-term effects, must be used cautiously in athletes. There is mixed evidence for the efficacy of hyaluronic acid injections. There is still limited evidence regarding the use of biologics.

Allopathic and Osteopathic Residents Perform Similarly on the Orthopedic In-Training Examination (OITE).

INTRODUCTION: There is a bias in the medical community that allopathic training is superior to osteopathic training, despite the lack of substantiation. The orthopedic in-training examination (OITE) is a yearly exam evaluating educational advancement and orthopedic surgery resident's scope of knowledge. The purpose of this study was to compare OITE scores between doctor of osteopathic medicine (DO) and medical doctor (MD) orthopedic surgery residents to determine whether any appreciable differences exist in the achievement levels between the 2 groups. METHODS: The American Academy of Orthopedic Surgeons 2019 OITE technical report, which reports the scores from the 2019 OITE for MDs and DOs, was evaluated to determine OITE scores for MD and DO residents. The progression of scores obtained during various postgraduate years (PGY) for both groups was also analyzed. MD and DO scores throughout PGY 1-5 were compared with independent t-tests. RESULTS: PGY-1 DO residents outperformed MD residents on the OITE (145.8 vs 138.8, p < 0.001). The mean scores achieved by DO and MD residents during PGY-2 (153.2 vs 153.2), 3 (176.2 vs 175.2), and 4 (182.0 vs 183.7) did not differ (p = 0.997, 0.440, and 0.149, respectively). However, for PGY-5, the mean scores for MD residents (188.6) were higher than those of DO residents (183.5, p < 0.001). Both groups had trends of improvement seen throughout PGY 1 to 5 years, with both groups showing an increase in average PGY scores when compared to each preceding PGY. CONCLUSION: This study provides evidence that DO and MD orthopedic surgery residents perform similarly on the OITE within PGY 2 to 4, thus displaying equivalencies in orthopedic knowledge within the majority of PGYs. Program directors at allopathic and osteopathic orthopedic residency programs should take this into account when considering applicants for residency.

Psychosocial interventions help facilitate recovery following musculoskeletal sports injuries: a systematic review.

Context: Recent research demonstrates a connection between psychological factors and return to play following a musculoskeletal sports injury. Although it has been shown that psychological factors can influence when and if an athlete returns to play, it is unclear if the implementation of psychosocial interventions during the recovery process can address these factors and potentially increase the likelihood of return to play after physical recovery from injury. Objective: To examine the efficacy of interventions designed to address psychosocial factors that influence return to play after sports injuries. Methods: A systematic review was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Pubmed, Embase, and Google Scholar databases were searched from the earliest entry through May 2018. Search terms included 'psychology,' 'sports injury,' 'anterior cruciate ligament injury,' 'anterior cruciate ligament reconstruction,' 'intervention,' 'return to play,' and 'return to sport.' Studies were included and reviewed if they reported on the efficacy of a psychosocial intervention program in injured athletes. Results: Initial searches of Pubmed, Embase, and Google Scholar databases identified 560 articles, 329 articles, and 34,400 hits, respectively. After inclusion and exclusion criteria were applied, eight articles remained that met inclusion criteria. Interventions of relaxation/guided imagery, positive self-talk, goal setting, counseling, emotional/written disclosure, and modeling videos were found to be effective interventions for promoting recovery after a musculoskeletal sports injury. These interventions facilitated positive mood changes, pain management, exercise compliance, and rehabilitation adherence. No study examined the effect of psychosocial interventions on return to play. Conclusion: This systematic review demonstrates that psychosocial interventions can facilitate post-injury recovery in athletes by promoting a positive emotional state and rehabilitation adherence. Further research is necessary to determine the most effective psychosocial interventions for specific psychological factors, the ideal duration of interventions, the best method of implementation following a sports injury, and the impact of these interventions on return to play.

Women's Sports Medicine Programs in the United States: an interdisciplinary approach to the care of girls and women.

Objectives: Multiple studies have shown that women are more susceptible to certain musculoskeletal (MSK) injuries than their male counterparts. In response to these identified differences, several institutions have established Women's Sports Medicine Programs (WSMPs). The purpose of this study was to determine the number of WSMPs and explore program characteristics such as geographic location, specialties represented, common conditions treated, program history, and patient population.Methods: An extensive internet search was conducted to identify WSMPs in the United States. The second part of this study involved a 13-question, anonymous, electronic survey that was distributed to the directors of identified WSMPs to gather further data. Descriptive statistics were used to analyze the data.Results: Nineteen WSMPs were identified and the majority have been in existence for 6 to 10 years (44.4%). The survey was delivered to 18 programs and 9 WSMP directors responded (50% response rate). The most commonly reported number of physicians, across all specialties, comprising the core network was two physicians (4 programs, 44.4%). Health care providers with fourteen different areas of specialization were identified across all programs. The most common conditions treated were patellofemoral pain syndrome (33.3%), stress fracture (33.3%), and ACL tear (22.2%). In 5 programs (55.5%), patients < 18 years of age accounted for less than 25% of total patients. Only 2 programs (22.2%) reported that >51% of patients were actively participating in sports.Conclusion: This study demonstrates that nineteen Women's Sports Medicine Programs have been established in the United States. These programs address conditions known to have a higher incidence in the active female population, however the WSMPs are not solely geared towards the treatment of active female athletes. The information provided in this study can serve as a guide for the development of future WSMPs, as well as, future research studies regarding WSMPs.

Biomimetic proteoglycans can molecularly engineer early osteoarthritic cartilage in vivo.

Biomimetic proteoglycans (BPGs) have the potential to treat osteoarthritis (OA) given that these molecules mimic the structure and properties of natural proteoglycans, which are significantly reduced in OA. We examined the effects of BPGs injected into the intra-articular space in an in vivo OA rabbit knee model and evaluated the effect on histological response, joint friction, and BPG distribution and retention. Rabbits underwent ACL transection to create an arthritic state after 5 weeks. OA rabbits were treated with BPGs or Euflexxa® (hyaluronic acid) intra-articular injections. Non-OA rabbits were injected similarly with BPGs; contralateral joints served as controls. The progression of OA and response to injections were evaluated using Mankin and gross grading systems indicating that mild OA was achieved in operated joints. The coefficient of friction (COF) of the intact knee joints were measured using a custom pendulum friction apparatus, showing that OA joints and OA + Euflexxa® joints demonstrated increased COF than non-operated controls, while BPG-injected non-OA and OA + BPGs were not significantly different from non-OA controls. Injected fluorescently labeled BPGs demonstrated that BPGs diffused into cartilage with localization in the pericellular region. © 2018 Orthopaedic Research Society.
