RESUMEN
PURPOSE: To evaluate the functional and graft survivorship outcomes of the three most common autograft options for primary anterior cruciate ligament reconstruction (ACLR)-hamstring tendon (HT), bone-patella-tendon-bone (BPTB), and quadriceps tendon (QT). METHODS: Patients captured by the New Zealand ACL registry who underwent a primary ACLR from 2014 to 2020 were considered for the study. Patients with associated knee injury (including meniscus, chondral, osseous, and additional ligamentous injury) and previous knee surgery were excluded. Comparison was made between HT, BPTB, and QT autografts with respect to Marx and KOOS (Knee Osteoarthritis Outcome Score) scores at minimum 2 years follow-up. In addition, graft survivorship was evaluated by comparing all-cause revision per 100 graft years and revision-free proportion at 2 years post-surgery. RESULTS: 2,582 patients (1,921 HT, 558 BPTB, 107 QT) were included in the study. Differences in adjusted functional outcomes between HT and BPTB were found at 12 months (mean Marx; HT 6.2; BPTB 7.1; P < 0.001) (mean KOOS Sport and Recreation; HT 75.1; BPTB 70.5; n.s.) and 24 months (mean KOOS Sports and Recreation; HT 79.2; BPTB 73.9; P < 0.001). QT was comparable to HT and BPTB in all functional scores at 12 months and 2 years. No statistically significant differences were found in revision rate between all three autograft groups up to 2 years post-surgery (revision rate per 100 graft years; HT 1.05; BPTB 0.80; QT 1.68; n.s. HT vs. BPTB; n.s. HT vs. QT; n.s. QT vs. BPTB). CONCLUSIONS: QT was found to be comparable to both HT and BPTB in all functional scores and revision rates up to 2 years post-surgery. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: Reverse total shoulder arthroplasty (RTSA) was traditionally reserved for the patient with rotator cuff tear arthropathy. As the indications for RTSA continue to expand, the role of RTSA in patients aged >70 years with glenohumeral arthritis and an intact rotator cuff remains unclear. AIM: To study the New Zealand Joint Registry (NZJR) and compare the outcomes of a primary Total Shoulder Arthroplasty (TSA), a primary RSA and an RSA performed for revision of a failed TSA in patients aged >70 years, to determine if there is clear evidence to support a primary RSA in those aged >70 years instead of a primary TSA METHOD: This is a retrospective study of the NZJR from 2000 to 2018. We included all primary TSAs, primary RTSAs, and those RTSAs that were performed for the revision of a failed TSA. We excluded those RTSAs that were performed for the revision of an RTSA or hemiarthroplasty. The primary outcome was the Oxford Shoulder Score (OSS) at 6 months and 5 years, with a secondary outcome being the subsequent revision rate. RESULTS: A total of 3449 primary TSAs, 4681 primary RTSAs, and 104 revision RTSAs were identified. The mean OSSs at 6 months for a primary TSA, a primary RTSA, and a revision RTSA were 39.5 ± 9.0, 35.5 ± 9.4, and 32.5 ± 9.7, respectively (P < .001, primary TSA vs. primary RSTA; P <.001, primary TSA vs. revision RTSA; P = .0252 primary RTSA vs. revision RTSA). The mean OSSs at 5 years for a primary TSA and a primary RTSA were 42.1 ± 7.5 vs. 39.8 ± 8.4, respectively (P < .001), with no results available for revision RTSA. The secondary outcome was the revision rate for those aged >70 years with osteoarthritis as their primary indication for surgery. The revision rates for a primary TSA and a primary RTSA were 0.53/100 component-years (95% confidence interval [CI] 0.38-0.72) and 0.51/100 component-years (95% CI 0.31-0.79), respectively (P = .193), which was not statistically significant. CONCLUSION: The TSA remains the gold standard for primary shoulder arthroplasty. For those individuals aged >70 years with osteoarthritis as their primary diagnosis, a primary TSA is associated with a higher OSS than and similar revision rates to a primary RTSA's. However, these patients must be counseled regarding the risk of subsequent cuff failure, as the outcomes from a revision RTSA are significantly inferior than those from a primary RTSA.

OBJECTIVE: This study was conducted to determine the prevalence of hazardous, harmful and dependent drinking among hostel-dwelling students on the main campus of the University of the Free State (UFS), and the influence of sex and academic year on the habit. METHOD: A quarter of all hostel-dwelling students of UFS were selected by systematic random sampling. Willing participants completed a questionnaire comprising a demographic section and the Alcohol Use Disorders Identification Test (AUDIT). RESULTS: Of the 339 participants with total AUDIT scores, 15.6% exhibited hazardous drinking, 4.1% harmful drinking and 5.6% alcohol dependence. Male students had a statistically significant higher prevalence (32.8%) of hazardous, harmful or dependent drinking than female students (18.9%). Women, however, are biologically more vulnerable to the ill effects of alcohol due to altered pharmacokinetics and pharmacodynamics of alcohol. In addition, intoxicated women suffer more biological and social risks. When the cut-off point for hazardous drinking was adapted to account for the increased biological vulnerability of women, the difference between female and male participants was no longer significant. First year male students were less likely to engage in unsafe drinking than senior students. Female students in the alcohol dependent category showed an increasing trend over advancing academic year. CONCLUSIONS: Follow-up studies are needed to confirm whether a significant difference in hazardous drinking of first year male students compared to seniors reflects the influence of university policy or merely precedes drinking acculturation.

Compartment syndrome complicating a ruptured Achilles tendon has previously been reported in a surgically treated patient. However--to our knowledge--this is the first report of compartment syndrome following conservative treatment. A 45-year-old man ruptured his Achilles tendon and elected to have treatment in an equinus cast. Three weeks later, he developed compartment syndrome and despite fasciotomy, required surgical debridement of his anterior compartment. Delay in both diagnosis and subsequent fasciotomy resulted in a poor outcome. Any suspicion of compartment syndrome mandates early compartmental pressure monitoring. The exact aetiology is uncertain but we speculate that the equinus position of his ankle combined with weight-bearing, was a major contributing factor.
