Introduction: Knee osteoarthritis (KOA), the most common chronic degenerative condition in an older population, accounts for many disabilities around the world. One of the most popular treatments is intra-articular injection of hyaluronic acid (HA) and platelet-rich plasma (PRP).

Objective: Prior studies have found that both HA and PRP had a therapeutic effect on KOA. This study aims to perform a systematic review regarding whether PRP is superior to HA for KOA.

Method: We conducted a comprehensive literature search using Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines for prospective randomized control trials (pRCTs) in three international databases PubMed, Google Scholar, and ScienceDirect from 2019-2022. Two researchers independently searched the reviews, extracted, and cross-checked the data. The disparity when choosing the literature was resolved by discussion. The modified Jadad was scale used to assess the quality of the included studies. Cochrane risk of bias 2 tool (RoB-2) was used for determininzg risk of bias.

Results: Twenty three studies were eligible for inclusion. Four pRCT with the highest Jadad score were selected as best evidence. Risk of bias assesment concluded two studies having a low risk of bias, one is high risk of bias, and the other possesses some concerns.. Three studies found no difference in patient-reported outcomes between PRP and HA group and one study concluded that PRP is more effective than HA in treating KOA.

Conclusion: Intra-articular injections of PRP and HA are effective interventions for KOA. However, there is not enough evidence of PRP superiority over HA.

Ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH) are bone-forming spinal conditions which inherently increase spine rigidity and place patients at a higher risk for thoracolumbar fractures. Due to the long lever-arm associated with their pathology, these fractures are frequently unstable and may significantly displace leading to catastrophic neurologic consequences. Operative and non-operative management are considerations in these fractures. However conservative measures including immobilization and bracing are typically reserved for non-displaced or incomplete fractures, or in patients for whom surgery poses a high risk. Thus, first line treatment is often surgery which has historically been an open posterior spinal fusion. Recent techniques such as minimally invasive surgery (MIS) and robotic surgery have shown promising lower complication rates as compared to open techniques, however these methods need to be further validated.

Osteopetrosis, a rare condition arising from osteoclast dysfunction, is characterised by increased bony density and obliteration of the intramedullary canal. While total knee arthroplasty (TKA) is preferred for osteoarthritic patients with osteopetrosis, inherent disease characteristics pose surgical challenges. This article presents a patient with osteopetrosis treated with robotic arm-assisted TKA (RA-TKA). This approach provided precise bone resection, obviates the need for intramedullary guides, minimizes saw disposal, and reduces surgical duration, with satisfactory short-term outcomes. RA-TKA may be an effective treatment for osteoarthritis in patients with osteopetrosis.

Since the recognition of MPFL as the primary soft-tissue restraint to lateral displacement of the patella, its reconstruction gained popularity either alone or in combination with other procedures. Today, although there are plenty of techniques described in the literature, there is no consensus regarding which one is better. MPFL reconstruction using an endobutton device has been proved to be a reliable option with satisfying clinical results. Single or dual tunnel can be done depending on surgeon's preference. For safer outcomes more randomized controlled trials should be done while authors should be more meticulous when it comes to surgical technique.

Background: Irrecoverable radial nerve palsy (RNP) leads to the inability to extend the wrist and fingers and significant reduction in grip strength. The aim was to assess the outcomes of treating non-recovering motor RNP using the modified Merle d'Aubigné tendon transfer method.

Materials and methods: A descriptive prospective study involved 33 patients between January 2017 and March 2019.

Results: Males constituted the majority (32/33 cases, 97%). The ratio of radial nerve and posterior interosseous nerve injuries was nearly equivalent (16/17). The mean extension range of the wrist was 48.6° ± 14.9° during finger extension and 30.9° ± 14.4° during finger flexion. The mean flexion range of the wrist was 34.8° ± 15.8° during finger extension and 42.6° ± 14.8° during finger flexion. 93.9% of patients achieved full finger extension when the wrist joint was extended beyond 10°. The mean angulation range of the index finger was 55.3° ± 7.4°. The Kapanji score achieved was 8.4 ± 1.2. The achieved grip strength was 65.4% compared to the unaffected side. The surgery did not induce radial deviation deformities of the wrist joint. 32/33 patients were satisfied with the surgical outcomes. 31/33 patients returned to their previous professions. 93.9% of patients achieved very good and good results, while 6.1% achieved fair results.

Conclusion: Treating irrecoverable radial nerve palsy using the modified Merle d'Aubigné tendon transfer method yields very good results. The utilization of the pronator teres for wrist extensor transfer and the flexor carpi radialis for finger extensor transfer is appropriate and contributes to limiting wrist joint radial deviation deformities. This modified technique has been researched and recommended by various authors worldwide.

In this article, we present an uptodate outline of acromioclavicular (AC) joint separation. A clear understanding of acromioclavicular joint injury in terms of the mechanism of injury, clinical picture, diagnostic imaging, and most updated surgical techniques used for the treatment can provide the best care for those patients. This article describes updated treatment strategies for AC separation, including type III AC separation which is known most controversial. Finally, we present a proposed treatment algorithm that can aid in the treatment of AC separation from the most updated evidence.

Background: Replacement arthroplasty surgery is a surgical procedure that is needed to restore the activity of a joint. Patient satisfaction regarding arthroplasty surgery is influenced by post-operative complication rate, ability to afford care, and quality of interaction. In this study, we assessed patients' postoperative complications, mobility, and pain management as proxies for their overall satisfaction with total joint replacement (TJR).

Methods: An anonymous web-based survey was conducted for patients who had undergone any total joint replacement surgery in the US. Respondents were adults living in the United States.

Results: 180 individuals met the inclusion criteria and responded to the survey. Age, education, gender, and race were fitted against the patient satisfaction level with the surgeon. While education [P=0.4720], gender [P=0.5097 ], and race [P=0.8183] were not significant, age in years [P=0.02340] was predictive of overall satisfaction levels [R2=0.0213]. When controlling for BMI, infection [P=0.0164], nerve damage [P=0.0250], delayed healing [P=0.0024], hematoma [P=0.0497], were more likely to occur in participants who have had a knee replacement, as compared to shoulder and hip replacement surgery. When controlling for mobility before surgery vs. mobility after surgery [P=0.0114], patients who selected the highest level of mobility before surgery were likely to select the highest level of mobility after surgery. Medicaid, Medicare, private insurance, employer-based insurance, and no insurance were fitted against the patient's self-reported difficulty in paying for their treatment/care. Although employer-based insurance [P=0.0790] was not significant in predicting difficulty in paying for the surgery, patients with Medicaid [P=0.0280], Medicare [P=0.0200], or private insurance [P=0.0343] did.

Conclusion: In this cohort, older patients were associated with having improved satisfaction with the surgeon who performed their joint replacement. Complications were higher in patients who underwent a knee arthroplasty compared to a shoulder or hip arthroplasty.

Introduction: Partial patellar tendon tears (PPTTs) are overuse injuries in sports with frequent jumping, such as basketball and volleyball. There are several treatment options, including both operative and non-operative modalities. Current literature is largely focused broadly on patellar tendinopathy; however, there are few studies which specifically evaluate treatment outcomes for PPTTs.

Objective: To systematically review the literature on treatment options, clinical outcomes, and return to sport (RTS) in athletes with a PPTT.

Methods: PubMed, Embase, and Cochrane were searched through May 1^st, 2023 for studies reporting treatment outcomes in athletes with partial patellar tendon tears. Data was extracted on the following topics: treatment modalities, surgical failures/reoperations, surgical complications, RTS, and postoperative time to RTS.

Results: The review covers 11 studies with 454 athletes: 343 males (86.2%) and 55 females (13.8%). The average age was 25.8 years, ranging from 15 to 55 years. 169 patients (37.2%) received only non-operative treatments, while 295 (65.0%) underwent surgery. 267 patients (92.1%) returned to sports after 3.9 months of treatment. The average follow-up was 55.8 months.

Conclusion: Our review of current literature on PPTTs in athletes illustrates over 90% return to sport following either conservative or surgical treatment. There is currently little data that directly compares the treatment options to establish an evidence-based "gold-standard" treatment plan. The data we present suggests that current treatment options are satisfactory but would benefit from future study.

While the role and benefit of perioperative intravenous (IV) antibiotics in patients undergoing total joint arthroplasty (TJA) is well-established, oral antibiotic use in TJA remains a controversial topic with wide variations in practice patterns. With this review, we aimed to better educate the orthopedic surgeon on when and how oral antibiotics may be used most effectively in TJA patients, and to identify gaps in the literature that could be clarified with targeted research. Extended oral antibiotic prophylaxis (EOAP) use in high-risk primary, aseptic revision, and exchange TJA for infection may be useful in decreasing periprosthetic joint infection (PJI) rates. When prescribing oral antibiotics either as EOAP or for draining wounds, patient factors, type of surgery, and type of infectious organisms should be considered in order to optimally prevent and treat PJI. It is important to maintain antibiotic stewardship by administering the proper duration, dose, and type of antibiotics and by consulting infectious disease when necessary.

Purpose: The number of total knee replacements (TKRs) performed per year has been increasing annually and it is estimated that by 2030 demand would reach 3.48 million procedures per year in the United States Of America. The prevalence of periprosthetic fractures (PPFs) around TKRs has followed this trend with incidences ranging from 0.3% to 3.5%. Distal femoral PPFs are associated with significant morbidity and mortality. When there is sufficient bone stock in the distal femur and a fracture pattern conducive to fixation, locking compression plating (LCP) and retrograde intramedullary nailing (RIMN) are commonly used fixation strategies. Conversely, in situations with loosening and deficient bone stock, a salvage procedure such as a distal femoral replacement is recognized as an alternative. This meta-analysis investigates the rates of non-union, re-operation, infection, and mortality for LCPs and RIMNs when performed for distal femoral PPFs fractures around TKRs.

Method: A search was conducted to identify articles relevant to the management of distal femoral PPFs around TKRs in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Articles meeting the inclusion criteria were then assessed for methodological quality using the methodological items for non-randomised studies (MINORS) criteria. Articles were reviewed, and data were compiled into tables for analysis.

Results: 10 articles met the inclusion criteria, reporting on 528 PPFs. The overall incidence of complications was: non-union 9.4%, re-operation 12.9%, infection 2.4%, and mortality 5.5%. This meta-analysis found no significant differences between RIMN and LCP in rates of non-union (9.2% vs 9.6%) re-operation (15.1% vs 11.3%), infection (2.1% vs 2.6%), and mortality (6.0% vs 5.2%), respectively.

Conclusion: This meta-analysis demonstrated no significant difference in rates of non-union, re-operation, infection, and mortality between RIMN and LCP and both remain valid surgical treatment options.
