Orthopaedics Current Research

This study will compare two different ways, to help people with their recovery from a broken shoulder. Patients with this injury are usually referred for physiotherapy appointments for advice on how to get their arm and shoulder working again

In this study, patients will be asked to follow one of two rehabilitation programmes. They will either be offered:  Outpatient physiotherapy appointments to be shown what exercises to do or advice and information about a self-directed exercise programme that can be done at home. Advice will be given by a health professional in the hospital clinic, and you will also be given a high-quality workbook to help guide your recovery.

Evaluation of safety and efficacy of a resorbable collagan IMplant in treatment of High Grade PArtical thiCkness Tear; A prosepctive, mulitcentre, randomized, control trial.

Patients who are 18 years and over, with a partial rotator cuff injury who’s symptoms persist following 3-6 months of conservative treatment are eligible for this study.

Impact study compares two types of surgery:

The rotator cuff is a group of muscles and their tendons that act to stabilize (hold in place) the shoulder. Torn rotator cuff tendons are common injuries that result in shoulder weakness and pain. These injuries can be treated with medications, injections, and physical therapy. However, when symptoms continue despite these treatments, surgery is often recommended to repair the injured tendon. An alternative to standard surgical procedures for repairing torn rotator cuff tendons involves applying a protective layer of collagen over the injured tendons to aid in healing and stop disease progression. Collagen is the most commonly found protein in the body and is present in the skin, bones, tendons and ligaments. The collagen is extracted from bovine Achilles tendons (from cows).  

The purpose of this study is to find out if the marketed REGENETEN™ Bioinductive Implant is better than standard repair techniques for surgically treating partial-thickness rotator cuff tears. Smith+Nephew is the company paying for the study and REGENETEN is one of their products.

Peri-Op Iron and Erythropoietin (EPO) Intervention Study 

Anaemia after major emergency surgery in older people with hip fractures is common and is associated with increased mortality, longer length of hospital stay and poorer quality of health. The POP-I trial aims to recruit patients 60 and over, who are anaemic in the postoperative period following either hip fractures. Participants who give their consent will be assigned randomly into one of three study groups: Usual care, Iron Infusion, or iron infusion and an injection that will stimulate red blood cell production.

This study will explore if additional exercise advice for people aged 50 and over who have broken their wrist helps with recovery.

After breaking their wrist, people are often provided with basic advice by the person who is treating them about how to get their wrist working again. WISE would like to find out if more detailed exercise advice given by a Physiotherapist will improve how quickly and how well they recover from a broken wrist.

This study compares surgery to sling immobilisation in the management of adults with a displaced fracture of the distal clavicle (Collarbone) in patients over the age of 18 years old with 21 days of injury. 

When the outer end of the collarbone has broken, parts of the bone may separate and not line up. This can rupture the ligaments connecting the collarbone to the shoulder blade. Doctors commonly treat this type of injury that have had with: A sling, to help support the shoulder while the bone heals naturally; or surgery that uses metal work to try the separated bone while they knit together naturally.  Both treatments work but we do not know which one works the best. The aim of this study is to find this out.

Following surgery for a hip fracture (broken hip) hospitals aim to help patients out of bed within 48 hours of surgery. Patients should also receive a minimum of 2 hours of rehabilitation per week. Patients who receive more than this seem to recover quicker and return home sooner. This study aims to find out if increasing the level of ward-based mobilisation activities for patients following hip fractures allows them to return home sooner.

Distal Radius Acute Fracture 3: Cast verus Splint; a randomised non-inferiority trial comparing clinical and cost-effectiveness of a standard cast versus removable splint in Adults with a distal fracture tat does not require Manipulation.

When a person breaks their wrist, the treatment usually involves a support for the injured wrist. This support provides pain relief. It also protects the fracture (the break) whilst it heals.

In most hospitals in the UK, people with a broken wrist are given a plaster cast. After 4 to 6 weeks, they go back to hospital to have the cast taken off.

The results of a recent research study show that a removable wrist splint might provide the wrist with the same amount of support as a cast.

The benefit of this is that you can take it off yourself at home, so you don’t need to have it removed at a hospital. This could be more convenient for you. Providing people with a splint instead of a cast might also save money for the NHS.

At the moment, doctors, physiotherapists and other healthcare professionals are not completely sure if having a splint gives the same level of pain relief and support as a cast.

In this study, we will directly compare people receiving a cast with people receiving a splint for treating broken wrists. We want to find out if levels of pain and the ability to do everyday tasks are similar between the two groups. We will also have a look at the cost of both treatment options to the NHS, and society as a whole.

Lidocaine Intravenous Trial

A broken hip is a very serious injury that requires surgery to repair or replace the broken bone followed by a period of recovery in hospital. Around a quarter of patients who have a hip fracture have an episode of ‘delirium’ following surgery. Delirium is a condition where the patient loses awareness of themselves and the environment, and has difficulty thinking clearly. Inflammation, caused by the hip fracture and by the surgery to repair the hip, is thought to be the root cause of delirium. 
This study investigates the use of a drug called ‘lidocaine’ to see if it reduces the risk of delirium during surgery for a hip fracture.

Randomised Controlled Trial of Specialist Vocational Rehabilitation and Psychological Support to Enhance Return to Work after Trauma.

Getting back to work, voluntary work or education after an injury can be difficult. Many patients with serious injuries can have difficulties returning to work because of the physical and psychologists’ effects of problems. This can lead to financial and other problems. Overall, being in work is better for health than unemployment or prolonged sick leave. We therefore want to find out the best of healing patients make a successful return voluntary work or education. The Rowtate study aims to test the return-to-work programme support versus the standard trauma care at people returning to work after traumatic injury.

PROximal Fracture of the Humerus: Evaluation by Randomisation Trial no. 2.

This study is investigating the best way to treat patients aged 65 and over who have broken the top end of the upper arm bone (humerus) near the shoulder where the bone is broken into more than two parts.

There are currently three commonly used treatment options for fractures of this kind, which are two types of joint replacement surgery or structured non-surgical treatment. It is currently not known what the ‘best’ treatment is so this study is comparing non-surgical treatment and two types of joint replacement; ‘hemiarthroplasty’ which involves replacing only the broken ‘ball’ of the joint (top end of the arm bone), or ‘Reverse Shoulder Arthroplasty’ which replaces both the ball and socket, but replaces the ball with a socket and the socket with a ball (hence ‘reverse’).

The clinical and cost-effectiveness of elective primary total knee replacement with PAtellar Resurfacing compared to selective patellar resurfacing. A pragmatic multicentre randomised controlled Trial with blinding.

Total knee replacement (TKR) is commonly used for treating severe arthritis, with over 100,000 performed annually in the UK. During TKR, surgeons can resurface the patella (replace the under surface of the kneecap with a plastic prosthesis) or leave the native patella to articulate with the femoral implant. Resurfacing the patella is initially more expensive (longer theatre time, higher implant cost, risk of additional post-operative complications), but in the long-term it can reduce the risk of on-going pain which can result in further surgery to resurface the patella. NICE recommends always resurfacing the patella rather than never doing so. NICE did not find sufficient evidence on selective resurfacing (intraoperative decision based on the state of the patellar surface and the patients' symptoms) to make a recommendation on that strategy, but did recommend specific research was conducted on this question. If effective, selective resurfacing could result in optimal individualised patient care. This study evaluates the clinical and cost-effectiveness of elective primary TKR with always patellar resurfacing compared to selective patellar resurfacing.

Hip Implant Prosthesis Programme for the Younger total hip replacement patient.

Over 100,000 hip replacements are performed each year in the UK. Around 90% of patients report good pain relief and mobility after surgery, and most implants last 25 years or more.

Primary hip replacement involves replacing a damaged hip joint with an artificial implant that has two main parts. One part goes into the leg bone and ends in a ball which fits into a socket or cup attached to the pelvis, making a ball-and-socket joint. Implants can be fixed to bone with cement (cemented), without cement (uncemented), or partially cemented (hybrid). Cost ranges from £500 for some cemented to £2,000 for some uncemented implants.

When an implant fails, for example due to loosening or wear, it has to be re-done. Revision is a major operation, typically costing the NHS over £10,000. Cemented hip implants are safe, inexpensive, have a long track-record, and offer the best value-for-money for men aged over 75 and women aged over 65 years. There is no high-quality evidence to suggest more expensive uncemented or hybrid implants are any better than cemented implants for younger patients. Yet three quarters of NHS patients aged under 70 years receive uncemented or hybrid implants.

This Programme of research aims to find out which hip implants are best for patients under 70 years of age.

This study aims to compare two different plates currently used in knee realignment surgery (high tibial osteotomy). The purpose of the metal plates is to maintain the correct realignment achieved at surgery whilst the bone heals. The two plates, TomoFix and ActivMotion are both used in current practice and comply safety regulations.

Once the knee correction has healed (approx. 12 months) the plate can be left in. Some patients may however experience discomfort that related to the plate and benefit from plate removal ,  about a year after their initial operation. The ActivMotion plate design is a smaller than the Tomofix and it is therefore potentially less likely to cause discomfort . It is anticipated that second operations for plate removal will be less frequent than for the Tomofix plate.

In this study we would like to compare the number of plates that need removal following surgery, assess pain levels in patients in the first two years following surgery and compare the amount of pain relief used in the immediate post-operative recovery period.

Participants will be asked to complete a questionnaire before they have their operation and twelve months after the operation to assess their pain and function. This information will be used to compare the outcome of the plates.

This study is a prospective, post-market, global, multi-center, non-controlled, observational clinical evaluation of the commercially available Persona® Partial knee implant. The primary objective of the study is to obtain survivorship data and assess clinical performance (outcomes) using outcome measurement tools (e.g. patient questionnaires), radiographic assessments and adverse event data.

In total, there will be 30 global sites in the US and Europe. In the UK, the multi-centre study is being conducted at four sites in England with a maximum of 40 patients at each centre. Male and female individuals aged 18 years and over, with a confirmed diagnosis of osteoarthritis and who qualify for unicompartmental (partial) knee surgery will be potentially eligible to take part. Each Investigator will offer study participation to each consecutive eligible patient who satisfies the Inclusion/Exclusion criteria for partial knee arthroplasty using the commercially available Partial Persona Knee.

Following completion of the informed consent process, participants will undergo preoperative clinical evaluations prior to their partial knee arthroplasty. Patients will then be asked to attend post-operative follow-up clinic visits at 3 months, 1 year, 2 year, 5 year and 10 year. At these follow-up visits, clinical and radiographic evaluations will be conducted.

Hip replacements are a very common operation for people with painful arthritis. However, sometimes these hip replacements need to be done again because of pain and loosening.  We think that similar things may lead to loss of bone density (thinning of the bones) and loosening of joint replacements.  Because of this there is concern that loss of bone density may increase the need for further surgery to correct the loose joint replacement.

The study aims to see if there are differences in bone density and other factors that may explain why some people need their hip replacements done again (revised) and some do not.

 Reverse or Anatomical replacement for Painful Shoulder Osteoarthritis, Differences between Interventions (RAPSODI): a multi-centre, pragmatic, parallel group, superiority randomised controlled trial. 

Patient aged 60 years or over with painful OA of the shoulder and an intact rotator cuff presenting to secondary care and through shared making, having completed non-surgical treatments, proceeding to shoulder replacement. In shoulder replacement surgery, doctors remove the damaged parts of the shoulder and replace them with plastic or metal parts. 

The RAPSODI-UK study compares two types of shoulder replacement: the Total shoulder  replacement, and the Reverse Shoulder replacement.  These are the two types of shoulder replacement that NHS doctors use most often for patients with arthritis who need a shoulder replacement.  

They both help to reduce pain, and maintain or improve movement. However, doctors genuinely don’t know yet which one works best.
