The purpose of this study was to investigate the outcome after surgical therapy of patients suffering from HO of the hip after treatment in ICU.

We retrospectively examined 39 patients with heterotopic ossification of the hip (18 bilateral and 21 unilateral). All patients have had history of ICU treatment for several reasons, such as craniocerebral injury (35 patients-90%), 2 patients with Guillain-Barre syndrome (5%), 1 patient with pulmonary druse (2.5%), and 1 patient with inflammatory bowel disease (2.5%). They all underwent surgical removal of HO and postoperative irradiation therapy. On the basis of plain radiographic findings, we evaluated the recurrent ossification after an 18-month follow-up period.

The evaluation of the average 18-months follow-up period showed relief of pain and clear improvement of range of motion in most of our patients. Specifically, improvement in the range of movement was observed in 41 hip joints (71.93%) in contrast to 16 hip joints (28.07%) that did not show any alteration post-operatively. No lesion re-occurrence was observed. There was only one complication of peroneal nerve paresis following HO excision.

The majority of our patients that were treated with surgical excision of the ectopic bone around the hip joint significantly improved their range of joint movement and were relieved from pain. Surgical excision seems to provide a superior quality of life in these patients, as they have a high risk for major complications due to their poor level of mobility.

Introduction: Osteochondral lesions of the talus may cause persistent joint pain requiring surgical treatment, which today can be performed arthroscopically. The purpose of this study is to evaluate the effectiveness of arthroscopic treatment of these lesions.

Material and Method: Seventeen patients (7 males and 10 females) underwent ankle arthroscopy from 1998 through June 2002 for treatment of osteochondral lesions of the talus. Their age ranged from 11 – 68 years. The right talus was affected in 12 and the left in 5 patients. All but one had a history of previous trauma, for which they had been treated conservatively for at least 6 months.

Bone scanning, CT and MRI were performed for lesion staging according to Brent and Harty. One patient was stage I, 2 were stage II, 7 were stage III, and 7 were stage IV.

The patients underwent ankle arthroscopy without use of a distractor. Inspection of the joint was followed by shaving and debridement of the lesion with or without drilling.

Results: Follow-up had a mean duration of 15 months (range 8 – 24 months). Outcome was evaluated with the Ogilvie-Harris score for pain, swelling, stiffness, limp and patient activity level. All patients had excellent or good results. In all cases there was a reduction in lesion size.

Conclusions: Arthroscopy is effective for treatment of osteochondral lesions of the talus. It causes less morbidity than open surgery and patients are able to follow an early mobilization and rehabilitation protocol. However, specialized surgical tools, as well as an in-depth knowledge of joint anatomy are required to avoid iatrogenic damage.

Introduction: High tibial osteotomy is an established procedure for the mid-term treatment of unicompartmental osteoarthritis of the knee. Nevertheless, it produces anatomic alterations of the proximal part of tibia, which might affect the later performance of TKR. These anatomic changes are basically patella infera and medialization of the tibial medullary canal with respect to the tibial plateau (tibial condilar offset).

Material and Method: The purpose of the present retrospective study is the evaluation of the above mentioned anatomic changes, caused by high tibial valgus osteotomy (Mittelmeier’s technique). For this purpose we studied the X-rays of 44 kness (pre-op, p-op and 1 year p-op) that had under gone the above procedure.

Results: We didn’t find any statistically significant difference of the postoperative position of the patella with respect to the preoperative one, whereas there was definite medialization of the tibial anatomic axis with respect to the preoperative situation. The latter change was directly correlated with the degree of valgus correction. The mean change of the tibial anatomic axis (as estimated by the value of the tibial condylar offset ratio) was 15%.

Conclusions: Although Mittelmeier’s high tibial valgus osteotomy does not cause any significant alteration of the position of the patella, it does alter the relationship of the tibial medullary canal with respect to the tibial plateau in direct correlation with the degree of valgus correction. Thus, the performance of TKR after proximal tibial osteotomy necessitates a thorough preoperative plan and the selection of the appropriate implant.
