Revision shoulder replacement is a procedure used to treat problems that can develop after a previous shoulder replacement. This involves removing and replacing some or all of the existing implanted components, and addressing any changes in the surrounding bone and soft tissues.
Over time, a shoulder replacement may no longer function as expected. This can occur due to wear of the implant, loosening, instability, infection, or changes in the rotator cuff or bone. When this happens, revision surgery may be considered to improve comfort and restore function.
Revision procedures are often more complex than the initial (primary) shoulder replacement. This is due to factors such as bone loss, scar tissue, muscle weakness, or well-fixed previous implants which need to be removed.
The condition of the bone and soft tissues is an important consideration, as this can influence both the type of revision required and expected outcomes. General health, activity level, and recovery goals are also taken into account when considering whether revision surgery may be appropriate.
Not all patients with adverse symptoms after shoulder replacement will require revision surgery.
In some cases, non-surgical management or monitoring alone may be more suitable, depending on the nature and severity of the problem.
Your shoulder is assessed to understand how it is functioning and where the main issues are.
This includes evaluating:
Imaging is used to assess both the implant and the underlying bone and soft tissues.
This may include:
Revision shoulder replacement is tailored to the underlying problem and the condition of the implant, bone, and surrounding soft tissues. The procedure may involve removing and replacing some or all of the existing components and reconstructing the joint to restore stability and function.
Removal of existing well-fixed metallic components can be difficult and sometimes involves creating a controlled split in bone, for example in the humeral shaft to remove the stem part of an existing replacement.
Bone loss is frequently encountered and requires bone grafting or other techniques to rectify.
Existing parts of the shoulder replacement may be removed and replaced with new components.
Occasionally a worn part can be exchanged for a new one with a relatively simple procedure.
An anatomic shoulder replacement may be revised to a reverse shoulder replacement if it has worn out, come loose, or the rotator cuff has torn. A torn rotator cuff cannot be repaired like it can be in a normal shoulder when a shoulder replacement has been performed.
A failed anatomic replacement can only very rarely be replaced with another of the same, and most often is revised to a reverse replacement.
This is usually revised to another reverse replacement with restoration of lost bone stock on the glenoid side, humeral side, or both. It is more complex than revising an anatomic replacement to a reverse.
In most cases the ball (glenosphere) has loosened from bone while the stem has remained sound. A new one can be implanted usually with bone grafting behind it on the socket.
In some cases, it is not possible to reimplant a reverse replacement and a salvage option is to convert it to a hemiarthroplasty (half replacement). This is where a ball is replaced on the top of the humeral stem only, and moves on the residual bone left in the socket. Pain relief is usually reasonable, but movement is generally limited.
Bone loss around the joint during revision surgery is commonly encountered and may be addressed using specialised implants, metallic augments, or bone grafting techniques to support implant fixation.
Revision surgery often involves replacing lost bone on the glenoid side of the shoulder. This can be harvested from the hip (iliac crest) through a 3 cm incision during the same procedure. Donated bone or artificial bone substitutes can be used in some circumstances, usually when less structural demand is placed on the graft.
If the defect is too large a custom-made component made from printed titanium can be created to any size and shape to fill the defect
Techniques may be used to improve joint stability where instability or dislocation has occurred. This is usually in the context of reverse replacement and initially involves swapping out the existing plastic liner for a thicker one, and exchanging the ball (glenosphere) for a larger one. This is a relatively simple type of revision with a quick recovery.
In cases of infection, revision may involve staged procedures, including removal of the implant, treatment of infection, and later re-implantation. A temporary spacer filled with antibiotics may need to be left in the shoulder for a period of months in between removal of the original prosthesis and implantation of a new one once the infection has been fully treated.
Your arm will usually be supported in a sling for several weeks, usually 6, to protect the repair. Gentle, guided movement begins early, with exercises focused on maintaining basic mobility while allowing healing.
Physiotherapy plays an important role and progresses in stages, depending on the type of revision performed.
Over time, exercises are introduced to improve:
The pace of progression varies between individuals and depends on factors such as bone quality, soft tissue condition, and the complexity of the surgery.
Most patients are able to return to light daily activities within the first few weeks, with gradual improvement over time.
As a general guide:
Full recovery can take up to 12 months
The aim of revision surgery is to improve pain and function. Outcomes can vary depending on the reason for revision and the condition of the shoulder. In many cases, meaningful improvement in comfort and function can be achieved, although movement and strength may not return to the same level as a primary shoulder replacement.
Your rehabilitation plan will be tailored to your procedure.
Risks associated with most surgical procedures may include:
Steps are taken before, during, and after surgery to help reduce these risks.
The likelihood of these risks varies depending on the reason for revision, bone quality, and overall health.
The aim of revision shoulder replacement is to improve pain and restore function.
Outcomes can vary depending on:
Many patients experience meaningful improvement in comfort and daily function. Outcomes may not be the same as a primary shoulder replacement, particularly in more complex cases.
The decision to proceed with revision surgery is individual. It involves weighing the potential benefits of improved pain and function against the risks of surgery. Revision shoulder replacement is a more complex procedure, and careful assessment and planning are important when considering treatment options. As part of this process, patients may also wish to consider factors such as a surgeon’s training, experience in managing complex shoulder conditions, communication style, and the level of support provided throughout the surgical journey.
Dr Richard Dallalana will discuss these considerations with you in the context of your specific shoulder condition, previous surgery, and treatment goals to support informed decision-making. He has particular expertise in revision surgery and complex reconstruction techniques.
Non-surgical treatments are almost always utilised before considering joint replacement and may include:
These treatments aim to manage symptoms but do not reverse advanced joint degeneration.
Suitability depends on symptom severity and level of arthritis.
Some patients choose to delay surgery while managing symptoms with non-operative treatment. In certain situations, progressive joint damage, stiffness, or muscle changes may influence future treatment options.
It is sometimes safe to delay surgery, particularly when young, and at other times it is best to undergo replacement before advanced changes such as bone erosion occur limiting options. Regular review allows symptoms, function, and imaging findings to be monitored so that treatment decisions can be adjusted when needed.
Some discomfort is expected after surgery, particularly in the early stages. Pain is managed using a structured, multimodal approach and typically improves steadily as healing progresses. Pain control in the first day is greatly assisted by a nerve block which will be offered. Beyond the first day tablets alone are adequate to control pain, and strong medication such as opiates like endone or palexia are not needed for more than a few days. Pain is well controlled by the second week after surgery, Most patients are surprised at how quickly pain settles and this relates somewhat to the painful arthritic bone being removed during the surgery.
Hospital stay is usually short: 2 days in 95% of cases.
Discharge planning focuses on ensuring you feel safe, comfortable, and supported before returning home.
Inpatient rehabilitation is required on some occasions particularly if there are no supports around the home and this is arranged during your hospital stay.
Physiotherapy begins day 1 after surgery, initially focusing on gentle, protected movement.
You will be seen by the physiotherapy team in the hospital and shown how to do the exercises, and a printed instruction sheet is provided to keep these going at home. These instructions will cover the first 6 weeks, and beyond that exercise progression and finalising all aspects of your rehabilitation will be coordinated by a community physio. This can be with your own chosen practitioner, or one recommended by Mr. Dallalana.
Driving is generally resumed once the sling is no longer required and you can safely control the vehicle. This varies between individuals but is at the 6 week point in most cases.
Return-to-work timing depends on the physical demands of your job. Sedentary roles may be possible earlier, while physically demanding work often requires a longer recovery period and a graded return. Office work can commence within days if needed and the sling can be removed to use a keyboard.
In most cases movement is very close to that of a normal shoulder, but not at 100%. Pre-operative stiffness, muscle health, and adherence to rehabilitation all influence outcomes. It is rare to not have a high range of motion or to have a limitation enough to impair activities.
Almost everything is permitted after anatomic shoulder replacement.
Some very high-load or dangerous activities may be discouraged to help protect the joint over time. Guidance on allowed activities is tailored to your shoulder, implant configuration, and lifestyle goals.
Barring any major complication, a meaningful improvement in pain and shoulder function following surgery is expected. Specific outcomes vary depending on individual shoulder condition, rotator cuff health, rehabilitation participation, and overall health factors.
During consultation, Dr Richard Dallalana discusses expected benefits and limitations of surgery based on individual clinical findings.
Shoulder replacement surgery is commonly performed to improve comfort, movement, and ability to perform daily activities when shoulder arthritis or joint damage significantly affects function.
Modern shoulder replacement implants are designed for long-term use. Longevity varies depending on factors such as implant positioning, bone quality, activity level, and overall shoulder health.
It is rare to require repeat surgery within 10 years (<4%), and most will last for 15 to 20 years.
