Arthroscopic repair of isolated meniscal tears in patients 18 years and younger.

BACKGROUND: Isolated meniscal tears in the skeletally immature patient are infrequent but well-recognized injuries. Although few studies have evaluated the pediatric and adolescent population, arthroscopic surgical repair remains the standard of care for patients in this age group with unstable meniscal tears. PURPOSE: To review our results of arthroscopic repair of isolated meniscal tears in pediatric and adolescent patients to further define future management of these injuries. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The records of all patients 18 years old or younger who underwent isolated meniscal repair between 1990 and 2005 were retrospectively reviewed. Forty-four patients (6 girls, 38 boys) with an average age of 15.8 years (range, 9.9-18.7 years) were included in this study, for a total of 45 isolated meniscal tears. Clinical examinations were performed, International Knee Documentation Committee forms were administered, and Tegner scores were determined at an average of 5.8 years (range, 2.5 months-13.8 years) postoperative follow-up. Three patients were lost to follow-up. RESULTS: The clinical success rate of arthroscopic meniscal repair was 80% for simple tears, 68% for displaced bucket-handle tears, and 13% for complex tears. Seventeen menisci (38% overall) failed initial repair at a mean of 17 months (range, 3-61 months) postoperatively and underwent repeat arthroscopic surgery (15 partial meniscectomies, 2 rerepair). The average Tegner and International Knee Documentation Committee scores were 8 (range, 5-9) and 89.4 (range, 79-99), respectively, at the time of final follow-up. Risk factors for failure included complex tears and rim width greater than 3 mm. CONCLUSION: Clinically successful repair of an isolated meniscal tear in patients 18 years or younger was variable depending on tear type, with complex tears and rim width 3 mm or greater being negative prognostic factors.

Improving limb salvage in critical ischemia with intermittent pneumatic compression: a controlled study with 18-month follow-up.

BACKGROUND: Intermittent pneumatic compression (IPC) is an effective method of leg inflow enhancement and amelioration of claudication in patients with peripheral arterial disease. This study evaluated the clinical efficacy of IPC in patients with chronic critical limb ischemia, tissue loss, and nonhealing wounds of the foot after limited foot surgery (toe or transmetatarsal amputation) on whom additional arterial revascularization had been exhausted. METHODS: Performed in a community and multidisciplinary health care clinic (1998 through 2004), this retrospective study comprises 2 groups. Group 1 (IPC group) consisted of 24 consecutive patients, median age 70 years (interquartile range [IQR], 68.7-71.3) years, who received IPC for tissue loss and nonhealing amputation wounds of the foot attributable to critical limb ischemia in addition to wound care. Group 2 (control group) consisted of 24 consecutive patients, median age 69 years (IQR, 65.7-70.3 years), who received wound care for tissue loss and nonhealing amputation wounds of the foot due to critical limb ischemia, without use of IPC. Stringent exclusion criteria applied. Group allocation of patients depended solely on their willingness to undergo IPC therapy. Vascular assessment included determination of the resting ankle-brachial pressure index, transcutaneous oximetry (TcPO(2)), duplex graft surveillance, and foot radiography. Outcome was considered favorable if complete healing and limb salvage occurred, and adverse if the patient had to undergo a below knee amputation subsequent to failure of wound healing. Follow-up was 18 months. Wound care consisted of weekly débridement and biologic dressings. IPC was delivered at an inflation pressure of 85 to 95 mm Hg, applied for 2 seconds with rapid rise (0.2 seconds), 3 cycles per minute; three 2-hourly sessions per day were requested. Compliance was closely monitored. RESULTS: Baseline differences in demography, cardiovascular risk factors (diabetes mellitus, smoking, hypertension, dyslipidemia, renal impairment), and severity of peripheral arterial disease (ankle-brachial indices, TcPO(2), prior arterial reconstruction) were not significant. The types of local foot amputation that occurred in the two groups were not significantly different. In the control group, foot wounds failed to heal in 20 patients (83%) and they underwent a below knee amputation; the remaining four (17%, 95% confidence interval [CI], 0.59%-32.7%) had complete healing and limb salvage. In the IPC group, 14 patients (58%, 95% CI, 37.1%-79.6%) had complete foot wound healing and limb salvage, and 10 (42%) underwent below knee amputation for nonhealing foot wounds. Wound healing and limb salvage were significantly better in the IPC group (P < .01, chi(2)). Compared with the IPC group, the odds ratio of limb loss in the control group was 7.0. On study completion, TcPO(2) on sitting was higher in the IPC group than in the control group (P = .0038). CONCLUSION: IPC used as an adjunct to wound care in patients with chronic critical limb ischemia and nonhealing amputation wounds/tissue loss improves the likelihood of wound healing and limb salvage when established treatment alternatives in current practice are lacking. This controlled study adds to the momentum of IPC clinical efficacy in critical limb ischemia set by previously published case series, compelling the pursuit of large scale multicentric level 1 studies to substantiate its actual clinical role, relative indications, and to enhance our insight into the pertinent physiologic mechanisms.

Wound complications after open Achilles tendon repair: an analysis of risk factors.

Operative treatment of Achilles tendon ruptures has the risk of wound complications. The purpose of this study is to determine the risk ratio for specific risk factors associated with wound related complications in patients with operatively treated Achilles tendon ruptures. Between 1978 and 2001, 167 open Achilles tendon repairs were done at our institution. Clinical data were retrospectively reviewed. Tobacco use, diabetes, age, gender, timing of surgery, body mass index and steroid use were evaluated as potential risk factors for wound healing complications. One patient was lost to follow-up and two patients had nonsimultaneous ruptures and only the first repair was included; the remaining patients were followed up until complete wound healing. There were 17 wound complications in 164 patients (10.4%). Significant risk factors for development of wound complications included tobacco use (p < 0.0001), steroid use (p = 0.0005), and female sex (p = 0.0400). For those patients who had one or more of the following risk factors: diabetes, tobacco use, or steroid use; eight of 19 (42.1%) had a complication, compared with nine of 145 (6.2%) for those without risk factors present (p < 0.0001). Surgeons doing open Achilles tendon repairs should be cognizant of the specific risk factors identifled in this study, because they might impact decision making with regard to operative versus nonoperative treatment.
