Results support the proposition that ACL injury predisposes knees to osteoarthritis, while ACL reconstruction surgery has a role in reducing the risk of developing degenerative changes at 10 years. However, returning to sports activities after ligament reconstruction may exacerbate the development of arthritis.

The pattern and type of inflammation seen in periprosthetic tissues obtained from hips with metal-on-metal and metal-on-polyethylene implants are very different. At the present time, we do not know the prevalence or clinical implications of these histologic findings, but we suggest that they may represent a novel mode of failure for some metal-on-metal joint replacements.

People experiencing homelessness have multiple complex health conditions yet are typically disengaged from primary health care services and place a significant burden on the acute health system. Barriers preventing people who are homeless from accessing primary care can be both personal and practical and include competing needs and priorities, illness and poor health, physical access to health services, difficulty in contacting services, medication security, and the affordability of health care. Differences in social status and perceptions of being judged can lead to relationship barriers to accessing primary care. Key solutions include prioritising access to stable housing, continuity of health care, specialised homeless general practice, hospital inreach, discharge planning and coordinated care, general practice outreach, and medical recovery centres.

IntroductionThe aim of the study was to compare short- and medium-term outcomes of transanal haemorrhoidal dearterialisation (THD) versus stapled haemorrhoidopexy (SH) for the treatment of second- and third-degree haemorrhoids.MethodsPatients with second- or third-degree haemorrhoids who failed conservative treatment were randomly allocated to THD or SH. Preoperative and postoperative symptoms, postoperative pain, time until return to normal activities, complications, patient satisfaction and recurrence rates were all assessed prospectively. Patients were followed up at 2, 8 months and when the study was completed.ResultsTwenty-eight patients (43% third degree) underwent THD and 24 (38% third degree) underwent SH. There were no significant differences in terms of postoperative pain, expected pain and analgesia requirements, but more THD patients returned to work within 4 days (P < 0.05). One THD patient developed a sub-mucosal haematoma after surgery, one SH patient occlusion of the rectal lumen and two rectal bleeding. At 8-month follow-up, two SH patients complained of faecal urgency. At 38-month follow-up (range 33–48 months), all short-term complications resolved. Patient satisfaction (“excellent/good outcome”, THD 89 vs. SH 87%) and recurrence rate (THD 14 vs. SH 13%) were similar in the two groups.ConclusionsShort-term results although similar seem to suggest SH may result in increased morbidity while return to work is quicker after THD. Medium-term results demonstrate that THD and SH have similar effectiveness.
