Arthroscopic treatment of solitary benign intra-articular lesions of the knee that cause mechanical symptoms.

PURPOSE: Most cases of knee locking and giving-way are caused by meniscal tears, loose bodies, or chondral lesions. Intra-articular benign tumors or tumor-like lesions can present with symptoms that resemble acute mechanical derangement. From a database of 2,200 arthroscopic interventions, 19 cases of intra-articular masses that presented with catching and locking symptoms in the knee were retrospectively analyzed. TYPE OF STUDY: Case series. METHODS: Our review revealed 33 patients with benign intra-articular masses in the knee joint. Nineteen of these individuals had sought medical attention for mechanical symptoms of catching or locking. The other 14 patients had a variety of symptoms including pain, swelling, and limitation of knee motion, but did not have mechanical symptoms. Age, sex, history of trauma, knee pain and effusion, medical illnesses, physical examination, arthroscopic findings, and pathologic findings were noted. RESULTS: The average age of the 6 male and 13 female patients was 37.5 years (range, 18 to 58 years). Preoperative magnetic resonance imaging confirmed the diagnosis in 7 cases and 12 cases were diagnosed during knee arthroscopy. The mean follow-up time after surgery was 52.5 months (range, 6 to 120 months). Pathologic examination of the lesions revealed 15 cases of localized pigmented villonodular synovitis (79%), 1 lipoma arborescens (5%), 1 pseudocyst (5%), and 2 nonspecific synovial masses (11%). None of the lesions showed malignant transformation. CONCLUSIONS: Solitary benign intra-articular lesions should be considered a rare cause of mechanical knee symptoms. Localized pigmented villonodular synovitis originating from the extensor mechanism or fat pad is the most common solitary intra-articular mass lesion in the knee and usually arises in the patellofemoral compartment. Recurrence has not occurred in our series, which includes 14 of 19 patients with greater than 24 months follow-up. LEVEL OF EVIDENCE: Level IV.

Iatrogenic medial dislocation of hallucal sesamoids with hallux varus in an adolescent.

BACKGROUND: Iatrogenic hallux varus is a rare deformity linked to bunion surgery at late adult age. Here reported is the first adolescent case of acquired hallux varus and medial dislocation of both sesamoid bones. CASE REPORT: The patient had had a surgical intervention under his first metatarsophalangeal joint when he was 10 years old. Correction of the deformity with a tendon transfer and medial capsular release alone-as was recommended for adults-was impossible in this adolescent, 8 years after the index surgery. Excision of the contracted medial structures and repair of the lateral retinaculum of the fibular sesamoid obtained a perfect correction of the dislocated sesamoid bones.

[A comparison between single- and two-staged bilateral total knee arthroplasty operations in terms of the amount of blood loss and transfusion, perioperative complications, hospital stay, and cost-effectiveness].

OBJECTIVES: We compared bilateral total knee arthroplasty (TKA) operations performed at a single session or at two separate sessions with respect to perioperative complications, the amount of blood loss and transfusion, the length of hospital stay, and the overall cost. METHODS: The study included 39 patients (34 females, 5 males; mean age 68.1 years; range 52 to 88 years) and 16 patients (13 females, 3 males; mean age 66.8 years; range 52 to 83 years) who underwent bilateral TKA for osteoarthritis at a single session and at two separate sessions, respectively. Staged operations were interspersed with a mean interval of 8.3 months (range 2 to 24 months). The two groups were compared with respect to perioperative complications, the amount of blood loss and transfusion, the length of hospitalization, and the overall cost. RESULTS: The amount of blood loss and transfusion, the length of intensive care unit stay, and the occurrence of perioperative complications did not differ significantly between single- and two-staged operations (p>0.05). However, the mean length of hospital stay (10.48 days versus 17.19 days; p=0.01) and the mean overall cost (p=0.03) were significantly less in single-staged operations. Perioperative complications accounted for 12.8% (n=5) and 25% (n=4) in single- and two-staged operations, respectively, all of which developed in patients who had a preexisting cardiologic disease. CONCLUSION: In view of its advantages, single-staged bilateral TKA seems to be an appropriate alternative in selected patients.

Benign noninfectious subcutaneous emphysema of the hand.

A 17-year-old girl presented pain and subcutaneous crepitation in the left hand. Because of lack of systemic symptoms, non-infectious cause was considered. Radiographic and magnetic resonance imaging revealed subcutaneous emphysema. A chest x-ray was reported as normal but chest computerised tomography revealed pneumomediastinum. On the third day of the hospitalisation, subcutaneous emphysema spread to arm, shoulder, head, left hemithorax, back, bilateral supraclavicular, cervical, submandibular and periorbital regions. Pneumomediastinum and subcutaneous emphysema disappeared during 6 weeks of follow up with conservative methods. This might have prevented unnecessary surgical intervention. This report demonstrates that benign non-infectious subcutaneous emphysema of the hand due to pneumomediastinum should be kept in mind in hand surgery.

[Arthroscopic assisted biceps tenodesis].

OBJECTIVES: Functional results of arthroscopic assisted biceps tenodesis were evaluated in patients with chronic biceps tendinitis. METHODS: The study included six patients (4 women, 2 men, mean age 55 years, range 47 to 60 years) who underwent arthroscopic assisted biceps tenodesis with a diagnosis of chronic biceps tendinitis. During tenodesis, the biceps tendon was secured with the use of key-hole technique in one patient, and with suture anchors in five patients. The patients were evaluated by the Constant shoulder scoring system. The mean follow-up was 12 months (range 6 to 36 months). RESULTS: All the patients had shoulder impingement syndrome, five patients had rotator cuff lesions, and one patient had os acromiale. The mean preoperative and postoperative Constant scores were 62 (range 60 to 65) and 84.2 (range 82 to 87), respectively. All patients returned to work within a mean of six weeks. No complications were observed during follow-up. CONCLUSION: Arthroscopic assisted biceps tenodesis may give successful results in patients with chronic biceps tendinitis with coexistent shoulder impingement syndrome or rotator cuff lesions.

[Arthroscopic capsular release for frozen shoulder].

OBJECTIVES: This study was designed to evaluate the results and technical considerations of arthroscopic capsular release of the glenohumeral joint in frozen shoulder disease. METHODS: Arthroscopic capsular release was performed in 16 patients (11 women, 5 men; mean age 51 years; range 40 to 60 years) unresponsive to physical therapy. The affected shoulder was on the right in 10 patients, and on the left in six, being on the dominant side in 12 patients. The duration of the patients' complaints ranged from six to 24 months. Preoperatively, the mean forward flexion was 92 degrees, external rotation was 14 degrees; the ranges of internal rotation were the trochanter in four patients, the gluteal region in seven patients, the lumbosacral region in one patient, the L3 level in one patient, and T12 level in three patients. Functional evaluations were made according to the Constant scoring system. The mean follow-up was 17.3 months (range 12 to 30 months). RESULTS: Postoperatively, the mean forward flexion and external rotation increased to 135 and 27 degrees, respectively. Internal rotation reached the gluteal region in two patients, the lumbosacral region in two patients, the L3 level in two patients, T12 level in nine patients, and the interscapular region in one patient. The mean Constant score improved by 47 points. CONCLUSION: Arthroscopic capsular release is a safe and effective surgical procedure in the management of frozen shoulder disease unresponsive to conservative treatment.

[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.

[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.
