The serum levels of calcium, phosphorus, ALP and iPTH before and one year after PTX were measured to evaluate the control of SHPT. Changes in bone mineral density (BMD) was determined by comparing x-ray images at pre-PTX and the final follow-up.
We attempted to have all patients return to assess the functional outcomes of the knee. Patients who returned fulfilled a Lysholm score and Tegner activity score. The results of QT repair were evaluated with particular attention to the knee ROMs measured using a goniometer (0°corresponding to full extension). The quadriceps muscle strength was reported based on the Kendall scale (12 (link)). In cases where the patient agreed, isokinetic muscle strength (IMS) tests were performed (IsoMed-2000; D&R Ferstl, Hemau, Germany). Also, the ability to walk without crutches and the occurrence of new ruptures after the procedure were recorded.
Anteroposterior (AP) and lateral radiographs with the knee flexed at 30° were taken. The patella height was measured according to Insall and Salvati index (the ratio of the longest patellar diagonal length to tendon length with the knee in 30° of flexion. A value of ≤0.8 indicated that the patella baja was present.
