- The Os centrale carpi is a relatively rare accessory carpal bone of the wrist that infrequently has been reported to cause symptoms. This report describes 2 cases where an apparently mobile Os centrale carpi caused painful clicking and crepitus and where the symptoms disappeared after arthroscopic removal of the ossicles.

- Purpose: The purpose of this study was to compare the clinical and radiographic outcome of arthroscopic partial and total meniscectomy.Type of Study: Retrospective outcome study.Methods: Thirty-six male patients with stable knees, no previous knee injury, and arthroscopic meniscectomy were matched into 2 groups: partial or total. In addition, a group of individuals with no known history of knee injury was matched to each patient with meniscectomy. All patients were re-examined by a clinical and radiographic examination 14 years after surgery.Results: At follow-up, radiographic changes, including Fairbank changes and joint space narrowing, were seen in 6 of 18 patients (33%) after partial meniscectomy and in 13 of 18 patients (72%) after total meniscectomy (P < .05). Joint space narrowing >50% of the joint space was seen in 1 patient after partial meniscectomy but was present in 7 patients after total meniscectomy. In the healthy controls, 4 of 36 patients (11%) had radiographic changes but none had joint space narrowing. Fourteen years after surgery almost 70% of patients had a Lysholm score >94 (i.e., normal). Only 5 of 36 patients (14%) in the total meniscectomy group had knee symptoms during activities of daily living. A similar decline in activity levels according to Tegner was seen over time in the control group and in the 2 meniscectomy groups. Conclusions: The frequency of radiographic changes 14 years after meniscectomy is related to the size of the meniscus removed, but the grades of these changes are low and have little influence on activity and knee function.

- PURPOSE: The objective of this study was to examine clinical presentation and medium-term outcome of patients with septic arthritis of the knee after anterior cruciate ligament (ACL) reconstruction. TYPE OF STUDY: Matched case control study. METHODS: From a consecutive case series of 575 patients who underwent ACL reconstruction from 1996 through 1999, we report on 10 patients (1.7%) with postoperative septic arthritis. These patients were compared with individually matched patients without infection, on average, 3 years after surgery. The examination included physical and radiographic evaluation, functional testing, KT-1000, Lysholm and Tegner scales, and the International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) form. RESULTS: The predominant clinical presentation among patients with septic arthritis was modest classic signs of local infection. However, all had fever and elevated sedimentation rate or high C-reactive protein. Bacterial cultures showed coagulase-negative Staphylococcus species in 6, Staphylococcus aureus in 1, and Propionibacteriaceae species in 1 patient. The diagnosis was established with a delay of approximately 5 days. All patients underwent arthroscopic debridement and lavage (2 cases) or continuous irrigation (8 cases), as well as antibiotic treatment. One experienced graft rupture caused by the infection. At the end of the follow-up evaluation, the infected patients reported significantly lower activity levels than the control subjects (mean Tegner score, 5.3 v 7.2, P =.03). No statistically significant differences were noted in mean Lysholm, IKDC, or KOOS scores, or in KT-1000 difference. Two infected patients scored lower on the Tegner and Lysholm scales postoperatively than they did preoperatively. When examining the causes of infection, we found contamination by coagulase-negative Staphylococcus on supposedly sterile suture clamps on 3 graft preparation boards. CONCLUSIONS: In cases of suspected septic arthritis after ACL reconstruction, laboratory studies and aspiration followed by culture testing should be performed liberally to avoid the otherwise frequently delayed diagnosis. The inferior postoperative activity level noted in infected patients appeared not to be secondary to graft failure but may be related to arthrofibrosis, cartilage damage, or recurring postinfectious meniscal tears.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: The goal of this study was to evaluate the effect of anterior cruciate ligament (ACL) reconstruction on the bone mineral area mass (BMA) in the calcaneus on the injured and noninjured sides. TYPE OF STUDY: A prospective cohort study with sequential assessments of bone mineral in the calcaneus before and after ACL reconstruction. METHODS: Thirty-four consecutive patients with a unilateral ACL rupture underwent arthroscopic reconstruction using patellar tendon autografts. The BMA was assessed bilaterally in the calcaneus using a gamma camera according to the dual-energy photon absorptiometry technique, before surgery and after 6 and 26 months. RESULTS: Thirty-one of 34 patients (20 men and 11 women) underwent all BMA measurements. The median age at index surgery was 27 (16 to 50) years, and the reconstruction was performed 12 (2 to 192) months after the injury. The median preoperative Tegner activity level increased from 3 (2 to 8) to 7 (2 to 9) at 26 months (P <.0001). The BMA in the calcaneus on both the injured and noninjured side decreased by 16% and 17% respectively from the preoperative measurement to the 26-month control (P =.0014; P =.0006). On all occasions, the BMA was lower on the injured side than on the noninjured side (P =.012). CONCLUSIONS: Patients with a unilateral ACL rupture had a lower BMA in the calcaneus on the injured side compared with the noninjured side. Although patients increased activity levels after reconstruction, the BMA in the calcaneus decreased on both the injured and the noninjured side up to 2 years after surgery. LEVEL OF EVIDENCE: Level II-1, prospective cohort study.

Substantial disability 3 months after arthroscopic partial meniscectomy: : A prospective study of patient-relevant outcomes
- 2000

Tidskriftsartikel (refereegranskat)abstract
- To our knowledge, this is the first prospective study using validated questionnaires to assess patient-relevant outcomes after arthroscopic partial meniscectomy. Data from the Knee Injury and Osteoarthritis Outcome Score (KOOS), the SF-36 Medical Outcomes Study Short-Form Health Survey, and the Lysholm Knee Scoring Scale were available for 74 consecutive patients (50 males, 24 females; mean age, 45 years) with isolated meniscus tear (n = 47) or meniscus tear combined with cartilage damage (n = 27). At postoperative follow-up (mean, 14.4 weeks) significant improvement was seen, but despite only minor pain and other symptoms postoperatively, significant physical disability and handicap were reported. Postoperatively, 30% of patients were active in sports compared with 63% before injury. A sedentary lifestyle was reported by 38% compared with 9% before injury. We conclude that patient-relevant outcomes provide additional information and should be assessed after arthroscopic partial meniscectomy. We further suggest that preoperative information for the meniscectomy patient should include a realistic expected functional outcome.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: The purpose of this study was to analyze and compare knee laxity in a group of patients with a unilateral right anterior cruciate ligament (ACL) rupture and a group of patients with a unilateral left ACL rupture. Another goal was to analyze and compare the knee laxity of the right and left knees in a group of persons without any known knee problems. TYPE OF STUDY: Prospective examination of the same patients preoperatively and 2 years after the reconstruction with examination of the healthy controls at 2 different occasions. METHODS: Group A was composed of 41 patients with a right-sided chronic ACL rupture, and group B was composed of 44 patients with a left-sided chronic ACL rupture. All patients underwent an arthroscopic ACL reconstruction using patellar tendon autograft. Group C was composed of 35 persons without any known knee problems. One experienced physiotherapist performed all the KT-1000 measurements and the clinical examinations. RESULTS: Group A displayed an increased difference in side-to-side laxity between the injured and non-injured side compared with group B in terms of both anterior and total knee laxity. This difference was found to be statistically significant preoperatively (P =.01, anterior; P =.001, total) and at follow-up evaluation 2 years after the index surgery (P =.008, anterior; P =.006, total). In group C, a significant increase was seen in absolute anterior and total laxity in the right knee compared with the left knee when 2 repeated measurements were performed (P <.0001 and P =.003, anterior; P <.0001 and P =.001, total). CONCLUSIONS: The KT-1000 arthrometer revealed a significant increase in laxity measurements in right knees compared with left knees. This difference was found both preoperatively and postoperatively in patients undergoing ACL reconstruction. The same thing was found in a group of persons without any known knee problems. LEVEL OF EVIDENCE: Level II.

- Purpose: The purpose of this study was 2-fold: to document the accuracy of a new measuring device and to intraoperatively compare the subacromial distance between controls and patients with impingement syndrome before and after arthroscopic subacromial decompression (ASD). Type of Study: Clinical study. Methods: When performing an ASD, it is important that bone resection is adequate. Today the correct subacromial distance after bone resection is only assessed by eye, directly or indirectly. The subacromial distance was measured between the anterolateral corner of the acromion and the supraspinatus tendon in the lateral decubitus position. The device was inserted 2 to 3 cm below the anterolateral acromion. There was no subacromial pathology among the controls (n = 15, mean age, 28 years). In 30 patients with impingement syndrome (average age, 53 years) an ASD was performed. The subacromial distance was measured after bursectomy and then after bone resection. Intraindividual and interindividual assessment was performed. Results: The mean value of the subacromial distance in controls was 16 mm, the 95% confidence limits between 14 and 18 mm. The mean value in the group of patients with impingement syndrome was 8 mm before and 16 mm after the decompression. Due to the pressure within the subacromial space, the subacromial distance increased 1 mm. Intraindividual measurements never varied more than 1 mm (n = 5). The correlation coefficient between the measurements by both authors was 0.99. Conclusions: In this study, we assessed and described the use of a measuring device that enables the surgeon to quantify the subacromial distance before and after bone resection. After bone resection, the mean value of the subacromial distance was well within the control values. The amount of bone resected varied from 5 to 13 mm. This new device enables documentation in clinical work as well as in research.
