[Diagnostic arthroscopy and mini-open lateral retinacular release in the treatment of excessive lateral compression syndrome].

OBJECTIVES: We investigated the efficacy of diagnostic arthroscopy and mini-open lateral retinacular release in the treatment of excessive lateral compression syndrome. METHODS: Twenty patients (21 knees) with excessive lateral compression syndrome underwent diagnostic arthroscopy and longitudinal mini-open lateral retinacular release. The patients were comprised of four men and 16 women (mean age 48.6 years; range 21 to 60 years). The results were evaluated according to the Lysholm scoring system. Preoperative and postoperative congruence angles were compared on the tangential patella roentgenograms. Statistical analysis was made using the Wilcoxon signed rank test. The mean follow-up was 10.5 months (range 3 to 18 months). RESULTS: The mean preoperative Lysholm score increased from 61.28 (range 29 to 76) to 85.57 (range 59 to 99) postoperatively. Only two patients (9%) exhibited decreases in the postoperative Lysholm scores. The mean preoperative congruence angle was +14.94 degrees. In all but two patients, the congruence angle was within normal ranges, with a mean correction of 12.42 degrees. None of the patients developed hemarthrosis postoperatively. Pain relief and functional recovery were achieved in 91% of patients. CONCLUSION: Lateral retinacular release and proper patellofemoral realignment may provide a successful outcome in patients presenting with anterior knee pain due to excessive lateral compression syndrome.

[Suprascapular nerve entrapment at the spinoglenoid notch secondary to a ganglion cyst].

Suprascapular neuropathy may occur as a result of traction, direct trauma, repetitive microtraumas, and extrinsic compression. A thirty-one-year-old man presented with non-traumatic complaints of right shoulder pain and stiffness. After exclusion of other causes associated with shoulder pain, a diagnosis of suprascapular nerve entrapment was considered. Electromyographic activity of the right shoulder was compared with that of the left side and involvement of the infraspinatus muscle was detected, with the supraspinatus muscle appearing normal. Magnetic resonance imaging revealed a ganglion cyst around the spinoglenoid notch. The patient underwent arthroscopic examination and open cyst excision. Arthroscopy did not show any labral tears. Pathological diagnosis was made as a cystic ganglion. On follow-up examinations, the patient's complaints disappeared and only minimal infraspinatus muscle atrophy was observed. Suprascapular nerve entrapment should be considered in the differential diagnosis of posterior shoulder pain.

[Arthroscopic treatment of rotator cuff calcifying tendinitis].

OBJECTIVES: We evaluated the effectiveness of arthroscopic treatment in patients with rotator cuff calcifying tendinitis unresponsive to conservative treatment. METHODS: Arthroscopic treatment was performed in 10 patients (6 females, 4 males; mean age 46 years; range 34 to 53 years) in whom pain and functional disability persisted for more than a year despite conservative therapy for rotator cuff calcifying tendinitis. Arthroscopic bursectomy was also carried out. One patient underwent repair for rotator cuff tear. The patients were evaluated before and after surgery with the use of Constant scores and direct radiographs. The mean follow-up period was 12 months (range 6 to 19 months). RESULTS: The mean Constant scores were 66 (range 45 to 70) and 93 (range 89 to 96) before surgery and on final examinations, respectively. Postoperative radiographs demonstrated incomplete removal of calcifications in four patients; however, complaints of pain disappeared in these patients and radiologic controls showed that residual deposits underwent spontaneous resorption. CONCLUSION: Arthroscopic removal of calcium deposits together with bursectomy seems to be effective and reliable in patients with chronic calcifying tendinitis unresponsive to conservative treatment.

Effects of methylprednisolone and betamethasone injections on the rotator cuff: an experimental study in rats.

Thirty-one female Sprague-Dawley rats were used to determine the effects of subacromial corticosteroid injections on the rotator cuff. The injection technique was tested in 6 animals, which were excluded from the study. The remaining 25 rats were randomly divided into three groups of 8 animals each; a single rat received no injections. Every other week for 8 weeks, one shoulder in each rat was injected with methylprednisolone, betamethasone, or saline in a dosage equivalent to that used in humans. The supraspinatus and infraspinatus tendons were removed 10 days after the last injection and evaluated. There were no pathologic changes in the tendons injected with saline. In 43% of the methylprednisolone-treated rats and 29% of the betamethasone-treated rats, the tendons were abnormally soft and light-colored. In 43% of the methylprednisolone group and 71% of the betamethasone group, fragmentation of collagen bundles and inflammatory cell infiltration were evident. Subacromial injections of methylprednisolone or betamethasone repeated frequently can cause deleterious changes in the normal structure of the rat rotator cuff. In light of these findings, therapy for subacromial impingement syndrome of the shoulder with frequent, repeated steroid injections is potentially harmful.

Tunnel enlargement after arthroscopic anterior cruciate ligament reconstruction: comparison of bone-patellar tendon-bone and hamstring autografts.

Bone tunnel enlargement associated with anterior cruciate ligament (ACL) reconstruction has recently become a topic of interest in the literature. This association was examined, along with the effect of femoral and tibial tunnel enlargement on the clinical results of ACL reconstruction performed with either bone-patellar tendon-bone (BPTB) or hamstring (HST) autografts. Forty-six patients underwent arthroscopic ACL reconstruction (23 receiving BPTB autograft and 23 HST) between March 1999 and July 2001. Thirty patients (13 receiving BPTB autograft and 17 HST) completed the last clinical and radiologic evaluations and were included in the study. The mean age of patients in the HST group was 29.8 years (range 18-39) and that in the BPTB group was 27.6 years (range 20-37). The mean follow-up period was 24.6 months (range 12-36) in HST group and 18.5 months (range 12-40) in BPTB group. The effect of tunnel enlargement on the clinical results was evaluated by comparing preoperative and postoperative Lysholm, Tegner, and International Knee Documentation Committee scores and ligament laxity measurements between and within the groups. Postoperative femoral and tibial tunnel diameters in both groups were significantly larger than their corresponding preoperative tunnel diameters. In an intergroup evaluation, the enlargement of the tibial tunnel was similar in both groups (P=.556), but the femoral tunnel diameter was significantly larger in the HST group than in the BPTB group (P>.001). Preoperative laxity of the knees significantly improved after the operations in both groups, but no difference between the groups was evident at the final follow-up visit. No correlation between tunnel widening and the clinical results of the BPTB and HST procedures was observed.

Hallucal sesamoid osteonecrosis: an overlooked cause of forefoot pain.

Four cases of osteonecrosis of hallucal sesamoids are reported here. Surgical excision of necrotic sesamoid tissue yielded satisfactory results, with the patients reporting no residual pain. Although it has not been frequently addressed in the literature, avascular necrosis of the sesamoid bones should be considered in the differential diagnosis of persistent forefoot pain.
