The importance of the mediopatellar synovial plica for chondromalacia patellae.

In 60 autopsy knee joints findings on morphology and topography of medio- and suprapatellar plicae and level of insertion of the medial vastus muscle in relation to localization and degree of severity of chondromalacia were determined. The middle fields were affected most frequently and severely with 70% (chondromalacia class II and III). Thirty specimen with mediopatellar plica could be identified out of which 29 (97%) had class II or III chondromalacia; out of 30 specimen without a plica 18 (60%) showed chondromalacia. Accordingly a significant correlation could be detected between the incidence of chondromalacia and that of a mediopatellar synovial plica. When measuring the level of insertion of the medial vastus muscle class III chondromalacia showed an average level of insertion of 11%, class II of 22%, and class O or I of 30%. These differences are statistically significant. Patellar index, patellar facet angle, and patellar depth angle did not show any direct correlation to chondromalacia. The question arises whether the involution anomaly of the genicular septa and the muscular changes are not a manifestation of the same developmental disorder, thus creating the basis for an imbalance of the dynamic functional structure.

Prospective long-term results of operative treatment in primary dislocation of the patella.

Among 53 prospectively studied patients who had undergone operative treatment of primary patellar dislocation, 9 (17%) suffered recurrence within an average follow-up of 6.5 years. All the redislocations occurred in female patients. The patients with recurrence also suffered first-time patellar dislocation in their unoperated knee during the follow-up significantly more often (P < 0.01) than the patients with stable knees. Patients with redislocations were more often dissatisfied with their outcome than the stable group, mainly because of annoying anterior knee pain (P < 0.05). Preoperatively the patients with redislocation had had more pronounced pathological patellofemoral congruity (Laurin's projections) in both the operated knee (P < 0.05) and the, at the time uninjured, control knee (P < 0.05). To improve the results of operative treatment for acute patellar dislocation, surgery should be aimed at correcting the underlying pathology. In grossly and symmetrically pathological cases of patellofemoral articulation, a distal realignment procedure should be considered. Otherwise conservative treatment may be justified.

Tuberculosis of the patella.

The case of an 8-year-old boy with tuberculous arthritis of the right knee in whom patellar disease was the only radiological abnormality is presented. The patellar findings were a large lytic area with sclerotic borders containing a dense image corresponding to a sequestrum. Open biopsy was necessary for diagnosis, since the radiological abnormalities are consistent with other chronic infectious diseases.

[Joint surface replacement of the lateral tibial plateau using patella transplantation].

A case of surgical reconstruction of the lateral tibial plateau after impression fracture (Type 41-B3.1) of an 47-year-old female is presented. Joint reconstruction was performed by using a free patellar graft. The 16-year follow-up shows a very good functional outcome without subjective complaints. This case underlines that performing patellar autografting for surgical reconstruction of severe injury of the tibial plateau seems to be a promising alternative especially considering young patients in spite of avoiding total knee replacement.
