“…In total knee arthroplasty, some authors suggest that the eversion of the patella leads to ischaemia and trauma of the tendon and, hence, to a postoperative patella infera [17]. On the other hand, a patella alta may be idiopathic [27], associated with neurological disorders [22] and be the cause of or a complication after patellar dislocations [28].…”

Purpose The aim of this prospective study was to evaluate the patellar height in 90°knee flexion. Methods A total of 85 patients with 95 knee joints were included in the study. Patellar height was measured according to the Blackburne-Peel, Labelle-Laurin, InsallSalvati, Linclau, and Caton-Deschamps methods in the whole group and in subgroups based on age, gender, and side.Results The BP-ratio showed a patella norma in 45 cases, and in 25 cases a patella alta and infera, respectively. The Labelle-Laurin method determined a patella norma in eight knees, in 35 a patella alta and in 52 a patella infera. The ISratio revealed a patella norma in 52 patients, a patella alta in six and in 37 a patella infera. The Linclau method demonstrated in 52 cases a patella norma, in 17 a patella alta and in 26 a patella infera. The CD-ratio showed the highest values of a patella norma among all tested methods in 67 knees, whereas a patella alta was evident in 13 and a patella infera in 15 cases. In the subgroups, discrepancies depended on the subgroup and method used. Conclusions Our results demonstrate a method-dependent discrepancy in the measurement of patellar height. A future study should evaluate this effect in a direct comparison between 30°and 90°knee flexion.

“…Tightening the MPFL graft may create an overload of patellofemoral cartilage, restrict the range of motion and result in a postoperative loss of knee flexion [5,6]. With a loose reconstruction, in contrast, patellar instability can exist continuously, and patellar dislocation can even recur [5,7].…”

“…This may change the patellofemoral joint forces and may lead to pain, restricted range of motion, redislocation and articular cartilage deterioration over time [15,16,42]. Therefore, individual MPFL reconstruction with anatomical footprint reconstruction at the patella and femur is fundamental.…”

The standard approach to reconstruct the medial patellofemoral ligament (MPFL) is by mini-open incision at its patellar insertion and femoral origin. At the medial patella rim, the MPFL insertion may be visualized in most cases by dissection during surgery. On the femur, it is more difficult to localize the MPFL remnants by a mini-open incision due to soft tissue covering the anatomical origin. Therefore, the femoral MPFL origin is usually identified by intraoperative lateral fluoroscopy. However, the insertion and origin of the MPFL at the patella and femur might be directly visualized using an arthroscopic extraarticular approach from the knee joint through a window of the synovial layer. This is especially helpful on the femoral side but also at the patella to find the individual anatomical MPFL footprints. Arthroscopic extraarticular reconstruction may then be performed using one additional medial mid-parapatellar portal. The major advantages of this technique are an individualized anatomical procedure, which is minimal invasive and cosmetically appealing. The aim of this study was to describe the arthroscopic extraarticular approach to the MPFL insertion at the patella and origin at the femur through synovial windows and to explain the procedure of arthroscopic MPFL reconstruction with a gracilis tendon autograft. Level of evidence Expert opinion, surgical technique, Level V.
