“…This titanium implant has shown excellent osseous integration in animal models and has been used successfully in revision hip surgery. 1,3,16,[30][31][32][33] It is composed of a 3D hexagonal lattice of titanium with high porosity (Figure 4a), manufactured using electron beam melting and designed to mimic cancellous bone. The highly porous titanium optimizes press-fit in bone due to high friction.…”

AimsReverse total shoulder arthroplasty (rTSA) can be used in complex cases when the glenoid requires reconstruction. In this study, a baseplate with composite bone autograft and a central trabecular titanium peg was implanted, and its migration was assessed for two years postoperatively using radiostereometric analysis (RSA).MethodsA total of 14 patients who underwent a rTSA with an autograft consented to participate. Of these, 11 had a primary rTSA using humeral head autograft and three had a revision rTSA with autograft harvested from the iliac crest. The mean age of the patients was 66 years (39 to 81). Tantalum beads were implanted in the scapula around the glenoid. RSA imaging (stereographic radiographs) was undertaken immediately postoperatively and at three, six, 12, and 24 months. Analysis was completed using model-based RSA software. Outcomes were collected preoperatively and at two years postoperatively, including the Oxford Shoulder Score, the American Shoulder and Elbow Score, and a visual analogue score for pain. A Constant score was also obtained for the assessment of strength and range of motion.ResultsRSA analysis showed a small increase in all translation and rotational values up to six months postoperatively, consistent with settling of the implant. The mean values plateaued by 12 months, with no evidence of further migration. In four patients, there was significant variation outside the mean, which corresponded to postoperative complications. There was a significant improvement in the clinical and patient-reported outcomes from the preoperative values to those at two years postoperatively (p < 0.001).ConclusionThese findings show, using RSA, that a glenoid baseplate composite of a trabecular titanium peg with autograft stabilizes within the glenoid about 12 months after surgery, and reinforce findings from a previous study of this implant/graft with CT scans at two years postoperatively, indicating that this type of structural composite results in sound early fixation.Cite this article: Bone Joint J 2023;105-B(8):912–919.

“…The patient received spinal-epidural anesthesia in the lumbar spine. We used a lateral parapatellar approach to facilitate access to both the fracture and knee joint surface; this helps release tight lateral structures in the valgus knee [ 13 ]. We performed a mid-line incision and arthrotomy lateral to the quadriceps tendon, patella, and the patellar ligament, respectively, preserving the subpatellar pyramid-shaped fat pad flap to help closure of the wound.…”

Knee Rheumatoid Arthritis With Lateral Tibial Plateau and Tibial Stress Fractures Managed With One-Stage Knee Joint Replacement

Rheumatoid arthritis (RA) is a chronic systemic disease that causes progressive joint damage, bony defects, and ligament imbalance. These sequelae of RA present major difficulties to surgeons during hip or knee arthroplasty. The presence of coexistent periarticular fractures adds to these difficulties and represents a surgical dilemma. No guidance exists within the literature for the medical and surgical management of complicated cases of RA with coexistent fractures. So far, the evidence has focused on fixation techniques, arthroplasty, and conservative management for periarticular fractures of osteoarthritic joints without significant degeneration of anatomical structures. We report a case of advanced knee RA with associated ipsilateral tibial plateau fracture and a tibial shaft stress fracture that was treated successfully with a single-stage joint replacement procedure. The case study presents a well-planned, single-stage arthroplasty with a lateral parapatellar approach as a management option that allows for early weight-bearing and restoration of function and provides a detailed guide for surgeons when managing similar cases.
