Long-term (ten- to 15-year) outcome of arthroscopically assisted Elmslie-Trillat tibial tubercle osteotomy.

Naveed MA, Ackroyd CE, Porteous AJ.Author information Royal Liverpool University Hospital, Prescot Road, Liverpool L7 8XP, UK. navemas@gmail.comAbstractWe present the ten- to 15-year follow-up of 31 patients (34 knees), who underwent an Elmslie-Trillat tibial tubercle osteotomy for chronic, severe patellar instability, unresponsive to non-operative treatment. The mean age of the patients at the time of surgery was 31 years (18 to 46) and they were reviewed post-operatively, at four years (2 to 8) and then at 12 years (10 to 15). All patients had pre-operative knee radiographs and Cox and Insall knee scores. Superolateral portal arthroscopy was performed per-operatively to document chondral damage and after the osteotomy to assess the stability of the patellofemoral joint. A total of 28 knees (82%) had a varying degree of damage to the articular surface. At final follow-up 25 patients (28 knees) were available for review and underwent clinical examination, radiographs of the knee, and Cox and Insall scoring. Six patients who had no arthroscopic chondral abnormality showed no or only early signs of osteoarthritis on final radiographs; while 12 patients with lower grade chondral damage (grade 1 to 2) showed early to moderate signs of osteoarthritis and six out of ten knees with higher grade chondral damage (grade 3 to 4) showed marked evidence of osteoarthritis; four of these had undergone a knee replacement. In the 22 patients (24 knees) with complete follow-up, 19 knees (79.2%) were reported to have a good or excellent outcome at four years, while 15 knees (62.5%) were reported to have the same at long-term follow-up. The functional and radiological results show that the extent of pre-operatively sustained chondral damage is directly related to the subsequent development of patellofemoral osteoarthritis.

[Reconstruction of medial patellofemoral ligament for recurrent patellar dislocation].

Zhang H, Hong L, Geng X, Wang X, Feng H.Author information Sports Medicine Service, Jishuitan Hospital, Beijing 100035, PR China.AbstractOBJECTIVE: To investigate the procedure and effectiveness of medial patellofemoral ligament (MPFL) reconstruction for the treatment of recurrent patellar dislocation. METHODS; Between June 2005 and September 2007, 29 patients with recurrent patellar dislocation underwent MPFL reconstruction with allograft semitendinosus or allograft anterior tibialis tendon. There were 6 males and 23 females with an average age of 20.3 years (range, 13-45 years). The patients suffered from 2-10 times patellar dislocation preoperatively. The average time between last dislocation and surgery was 43.9 months (range, 1-144 months). CT scan was performed to measure the tibial tuberosity-trochlear groove distance (TT-TG). The femoral tunnel was made at the origin of MPFL insertion, just inferior to the medial epicondyle. The double L-shape patellar tunnels were made on the medial rim of patella with 4.5 mm in diameter. The loop side of the graft was fixed with a bioabsorbable interference screw in the femoral tunnel both ends of the graft. For the TT-TG was more than 20 mm, a modified Elmslie-Trillat osteotomy was performed to correct the distal alignment of patella. The arthroscopic examination was also performed for loose body and lateral retinacular release.

… to Ficat, they were classified as follows, 1) recurrent dislocation: 5 cases 2) recurrent subluxation: 4 cases 3) permanent dislocation: 1 case.Their ages ranged from 15 to 43 years (average 20 years).There were 2 males and 8 females.The interaval between onset and operation averaged 64 months (1 month to 312 months).The diagnosis was determined by the clinical findings the hypermobility of the patella-Q angle, and the findings of the tangencial views of the patella, arthrography and arthroscopy.The operative procedures were used as follows, a): …
