Key features
Why TEAs fail
PatternASEPTIC LOOSENING (commonest late cause), polyethylene BUSHING WEAR (in linked implants, generating osteolysis), PERIPROSTHETIC FRACTURE, INFECTION, and instability/component failure - the elbow's small bones, thin cortices and high loads make these common.
Treatment
Central problem
PatternPERIPROSTHETIC BONE LOSS dictates the reconstruction: from simple BUSHING EXCHANGE for isolated wear, through re-cementing/LONGER STEMS and IMPACTION GRAFTING for cavitary loss, to ALLOGRAFT-PROSTHETIC COMPOSITE (APC) for MASSIVE segmental bone loss.
Treatment
Reality
PatternRevision TEA is COMPLICATION-HEAVY (periprosthetic fracture, ulnar neuropathy, wound problems, re-loosening, infection) with a real re-revision rate - so careful patient selection, planning and counselling are essential; the INFECTED TEA usually needs a STAGED revision.
Treatment
Critical Must-Knows
- Primary total elbow arthroplasty fails by several modes that the revision must address: ASEPTIC LOOSENING (the commonest late indication), polyethylene BUSHING WEAR in linked (semi-constrained) implants - which generates particulate debris, osteolysis and progressive loosening - PERIPROSTHETIC FRACTURE, deep INFECTION, and instability or mechanical component failure (e.g. fractured stems); the elbow's small bones, thin cortices and high lever-arm loads make these problems common.
- PERIPROSTHETIC BONE LOSS is the central reconstructive problem and largely dictates the strategy: isolated polyethylene wear with well-fixed stems can be treated by BUSHING EXCHANGE; cavitary/contained loss around a loose stem is managed by re-cementing with LONGER (revision) STEMS and IMPACTION (cancellous) GRAFTING; and MASSIVE SEGMENTAL bone loss is reconstructed with an ALLOGRAFT-PROSTHETIC COMPOSITE (APC) as a salvage.
- The ALLOGRAFT-PROSTHETIC COMPOSITE is a salvage option for massive bone loss about the elbow, typically using a semi-constrained (Coonrad-Morrey-type) prosthesis cemented into a structural allograft; midterm series report satisfactory function with allograft incorporation in most, but a HIGH complication rate (periprosthetic fracture, ulnar neuropathy, wound problems) - so it is reserved for severe deficiency and counselled accordingly.
- Even primary linked TEA has a HIGH COMPLICATION rate with a comparatively low revision rate, and the concerning long-term signals are INCREASING radiolucent lines around the ulnar component and polyethylene BUSHING WEAR - so revision surgery, performed in already-compromised bone and soft tissues, carries an even higher complication burden including periprosthetic fracture, ULNAR NEUROPATHY, wound healing problems, re-loosening and re-revision.
- INFECTION must be actively excluded before any revision (it is a not-uncommon cause of a painful loose TEA): work up with inflammatory markers, aspiration and intra-operative samples; the INFECTED TEA is generally managed by a STAGED protocol - debridement and component removal with an antibiotic spacer, organism-directed antibiotics, and delayed re-implantation once the infection is controlled (with resection arthroplasty as a fallback when re-implantation is not feasible).
- Outcomes of revision TEA are MODEST and the risks substantial, so SELECTION and PLANNING matter: define the failure mode and bone loss (CT), exclude infection, plan the implant and graft strategy, protect the ulnar nerve and triceps, and counsel the patient realistically about function and the elevated complication and re-revision rates - with permanent activity restrictions (typically a low lifting limit) to protect the reconstruction.
Clinical Pearls
- “Primary TEA fails by ASEPTIC LOOSENING (commonest late), BUSHING WEAR (linked implants -> osteolysis), PERIPROSTHETIC FRACTURE, INFECTION, instability.
- “PERIPROSTHETIC BONE LOSS dictates revision: bushing exchange -> longer stems + impaction grafting -> allograft-prosthetic composite (APC) for massive loss.
- “ALWAYS exclude infection first (staged revision if infected); revision TEA is complication-heavy (periprosthetic fracture, ulnar neuropathy, re-revision) - select and counsel carefully.

Modes of Failure & the Bone-loss Problem
Failure Modes and Why Bone Loss Decides the Revision
Total elbow arthroplasty fails by aseptic loosening (the commonest late cause), polyethylene bushing wear in linked implants (driving osteolysis and loosening), periprosthetic fracture, deep infection, and instability/component failure - all made common by the elbow's small bones, thin cortices and high loads. The revision strategy is dictated by periprosthetic bone loss: isolated wear with well-fixed stems needs only a bushing exchange; contained/cavitary loss around a loose stem needs longer revision stems with impaction grafting; and massive segmental loss needs an allograft-prosthetic composite (APC). Even primary linked TEA carries a high complication rate, and increasing ulnar radiolucent lines and bushing wear are the worrying long-term signals - so revision in compromised bone and soft tissues is complication- heavy, and infection must be excluded first.
Reconstruction Options & the Infected TEA
From Bushing Exchange to Allograft-Prosthetic Composite
- Bushing exchange. For isolated polyethylene wear with well-fixed stems - exchange the bushings (and treat any osteolysis), the least invasive revision.
- Re-stemming with impaction grafting. For a loose stem with contained/cavitary bone loss - re-cement longer revision stems with impaction (cancellous) grafting to restore the canal.
- Allograft-prosthetic composite (APC). For massive segmental bone loss - a semi-constrained prosthesis cemented into a structural allograft; satisfactory midterm function with allograft incorporation in most, but a high complication rate.
- The infected TEA - staged revision. Exclude infection in every painful/loose TEA (markers, aspiration, intra-operative samples); manage infection by debridement and component removal with an antibiotic spacer, organism-directed antibiotics, and delayed re-implantation once controlled (resection arthroplasty as fallback).
- Protect nerve and triceps. Identify/protect the ulnar nerve and preserve the triceps mechanism throughout.
Exclude Infection and Map the Bone Loss Before You Operate
The two errors that wreck a revision TEA are operating without excluding infection and operating without knowing the bone loss. Infection is a not-uncommon cause of a painful, loose TEA, and revising an unrecognised infected implant as if it were aseptic loosening will fail - so every painful/loose TEA needs inflammatory markers, aspiration and intra-operative samples, with a STAGED revision if infected. Equally, the reconstruction is chosen by the periprosthetic bone loss, so define it (usually on CT) before surgery to plan whether a bushing exchange, longer cemented stems with impaction grafting, or an allograft-prosthetic composite is needed and to have the implants and graft available. Throughout, protect the ulnar nerve and triceps, counsel the patient that revision TEA is complication-heavy with a real re-revision rate, and impose a permanent lifting restriction to protect the construct.
Evidence & Key Studies
Evidence
Coonrad-Morrey total elbow arthroplasty: 78 elbows at mean 5 years (failure signals)
Mansat P, Bonnevialle N, Rongieres M, Mansat M, Bonnevialle P • Journal of Shoulder and Elbow Surgery (2013)
Key Findings:
- Linked (Coonrad-Morrey) TEA treated a broad spectrum (inflammatory arthritis and trauma) with better results in rheumatoid than traumatic cases; survivorship was 97.7% at 5 years and 91.0% at 10 years with aseptic loosening as the endpoint.
- Despite a low revision rate, the complication rate was high (27 complications; 9 revised).
- Increasing radiolucent lines around the ulnar component over time and polyethylene bushing wear were specific concerns - the signals that precede revision.
Evidence
Allograft-prosthetic composite reconstruction for massive bone loss at the elbow
Laumonerie P, Granjou J, Tibbo ME, Massin V, Bonnevialle N, Mansat P • Orthopaedics & Traumatology: Surgery & Research (2022)
Key Findings:
- Revision of a loose TEA with massive bone loss is challenging; an allograft-prosthetic composite (with a semi-constrained Coonrad-Morrey prosthesis) is a salvage option - here aseptic loosening was the indication in all cases.
- Midterm functional outcomes were satisfactory with allograft incorporation in most (83%) and all prostheses well-fixed, and no further revisions were required.
- Complications were frequent (periprosthetic fracture, ulnar neuropathy, aseptic loosening, wound dehiscence), underlining the high complication burden of elbow revision for massive bone loss.
Evidence Attribution
According to PubMed, the failure signals of linked TEA - aseptic loosening as the survivorship endpoint, the high complication rate despite a low revision rate, and the specific concerns of increasing ulnar radiolucent lines and bushing wear - come from the cited Mansat series; the allograft-prosthetic composite as a salvage for massive bone loss, with satisfactory midterm function but frequent complications (periprosthetic fracture, ulnar neuropathy), from the cited Laumonerie series. The reconstruction ladder (bushing exchange, longer stems with impaction grafting, APC) and the staged management of the infected TEA are standard, well-established teaching.

Clinical Decision Scenarios
Practise clinical reasoning and management decisions out loud
Viva scenarioStandard
Clinical prompt
“Why do total elbow arthroplasties fail, and how do you work up a painful TEA before revision?”
Practical approach
Total elbow arthroplasties fail by several modes. The commonest late cause is aseptic loosening, and in linked, semi-constrained implants polyethylene bushing wear generates particulate debris, osteolysis and progressive loosening; other modes are periprosthetic fracture, deep infection, and instability or mechanical component failure such as a fractured stem. The elbow's small bones, thin cortices and high lever-arm loads make these common, and the worrying long-term radiographic signals are increasing radiolucent lines around the ulnar component and bushing wear. Before any revision I would define the failure mode and, critically, exclude infection, because infection is a not-uncommon cause of a painful loose TEA and revising an infected implant as if it were aseptic loosening will fail. So I would take a history and examination, inflammatory markers, and joint aspiration for culture, plan intra-operative samples, and obtain imaging - radiographs and a CT - to map the periprosthetic bone loss, because the bone loss dictates the reconstruction. I would also assess the ulnar nerve and triceps. Only once I have defined the mode of failure, excluded or confirmed infection, and mapped the bone loss would I plan the revision implant and graft strategy.
Key clinical points
Failure modes: aseptic loosening (commonest late), bushing wear/osteolysis (linked), periprosthetic fracture, infection, instability
Worrying signals: increasing ulnar radiolucent lines, bushing wear
Always exclude infection (markers, aspiration, intra-operative samples) before revision
CT to map periprosthetic bone loss (dictates reconstruction); assess ulnar nerve/triceps
Common pitfalls
Revising a missed infection as 'aseptic loosening'
Not mapping bone loss before surgery
Forgetting the ulnar nerve/triceps assessment

Viva scenarioStandard
Clinical prompt
“How does periprosthetic bone loss guide your revision TEA reconstruction?”
Practical approach
Periprosthetic bone loss is the central problem and largely dictates the reconstruction. If there is isolated polyethylene wear with well-fixed stems and minimal bone loss, the least invasive revision is a bushing exchange, treating any osteolysis at the same time. If a stem is loose with contained or cavitary bone loss, I would re-cement longer revision stems and use impaction grafting with cancellous bone to restore the canal and support the new stems. If there is massive segmental bone loss - for example a deficient distal humerus or proximal ulna - I would consider an allograft-prosthetic composite as a salvage, cementing a semi-constrained prosthesis into a structural allograft; midterm series show satisfactory function with allograft incorporation in most cases, but a high complication rate including periprosthetic fracture and ulnar neuropathy, so I would counsel accordingly. Throughout I would protect the ulnar nerve and the triceps mechanism, plan the implants and graft in advance from the CT, and, if infection is present, treat it first with a staged protocol before any definitive reconstruction. I would counsel the patient that revision elbow surgery is complication-heavy with a real re-revision rate and would impose a permanent lifting restriction to protect the construct.
Key clinical points
Isolated wear, well-fixed stems -> bushing exchange
Loose stem with cavitary loss -> longer cemented revision stems + impaction grafting
Massive segmental loss -> allograft-prosthetic composite (salvage; high complications)
Protect ulnar nerve/triceps; treat infection first (staged); permanent lifting restriction
Common pitfalls
Using a short stem in a deficient canal
Attempting APC without counselling the high complication rate
Operating before treating an established infection
